6.1 Accounting for Labour, Remuneration Systems & Labour Ratios
Key Takeaways Explain This Topic AI
Direct labour costs are directly traceable to specific cost units and charged to Work-in-Progress (WIP), whereas indirect labour costs are debited to the Production Overhead Control account.
Basic pay for overtime worked by direct workers is always classified as direct labour, but overtime premium is treated as an indirect production overhead unless the overtime was specifically requested by a customer to expedite their order.
Idle time is paid non-productive time: normal idle time is charged to production overhead rather than WIP, while exceptional abnormal idle time may be written off as an abnormal loss.
Straight piecework pays purely on output, differential piecework increases the rate per unit at higher output tiers, and incentive schemes like Halsey (50% bonus on time saved) and Rowan (bonus proportional to time saved over time allowed) reward production speed.
Labour turnover rate is calculated strictly as (Replacements / Average Workforce) × 100%, and the three labour operational ratios link through the governing identity: Activity Ratio = Efficiency Ratio × Capacity Ratio.

Accounting for Labour, Remuneration Systems & Labour Ratios
Core Principle: Labour costs represent a major element of prime cost and operational expenditure in both manufacturing and service organisations. Effective management accounting requires classifying labour effort into direct and indirect categories, accurately accounting for overtime and idle time in ledger accounts, selecting appropriate remuneration and incentive schemes, and monitoring workforce productivity through standardised performance ratios.
1. Direct vs. Indirect Labour Costs
Labour cost is the total financial consideration paid to employees in exchange for their time, skill, and physical or intellectual output. In cost and management accounting, labour is divided into two primary categories:
Direct Labour Costs
Direct labour consists of the wages paid to operational employees who are directly engaged in transforming raw materials into finished goods, or who deliver the core revenue-generating service. The key characteristic of direct labour is that it can be directly, economically, and unambiguously traced to a specific cost unit (job, batch, product, or service contract).
Examples: Assembly line workers in an automobile factory, machinists cutting fabric in a garment workshop, bricklayers on a construction site, and software programmers billing client-specific software modules.
Cost Classification: Direct labour forms an essential component of Prime Cost (alongside direct materials and direct expenses) and is debited directly to the Work-in-Progress (WIP) Control Account .
Indirect Labour Costs
Indirect labour comprises the remuneration paid to employees who support the operational infrastructure, maintain facilities, or manage operations, but whose effort cannot be traced directly or economically to individual finished units.
Examples: Factory supervisors, quality assurance inspectors, preventative maintenance technicians, fork-lift drivers and storekeepers, factory cleaners, security personnel, and administrative and sales personnel.
Cost Classification: Indirect labour forms part of Overheads . Factory-related indirect labour is debited to the Production Overhead Control Account , while administrative and sales staff salaries are charged to period overhead accounts (Administration Overhead and Selling & Distribution Overhead).
Dimension Direct Labour Indirect Labour
Traceability Traceable directly to specific cost units Cannot be traced to individual units without arbitrary allocation
Cost Category Prime Cost (Product Cost) Overhead Cost (Production or Non-Production Overhead)
Ledger Destination Work-in-Progress (WIP) Control Account Production Overhead Control Account (or Period Expense Accounts)
Inventory Valuation Capitalised into inventory under IAS 2 Factory indirect labour is absorbed into inventory; admin/selling is expensed
Behaviour with Output Typically varies directly with production volume Often fixed or stepped-fixed relative to production volume
2. Accounting Treatment of Overtime, Shift Premiums & Idle Time
One of the most frequently tested areas in ACCA Management Accounting is the distinction between basic wages and wage enhancements (premiums), and their respective accounting treatments.
Basic Pay vs. Overtime Premium
When an employee works hours in excess of their standard contractual working week (for example, exceeding 40 hours per week), they are typically compensated at an enhanced rate, such as "time-and-a-half" (1.5 × basic rate) or "double-time" (2.0 × basic rate).
Total earnings for overtime hours are split into two distinct elements:
Basic Pay for Overtime Hours: The standard contractual hourly rate multiplied by the overtime hours worked.
Overtime Premium: The additional bonus or enhancement paid per hour above the basic contractual rate. Total Overtime Pay = ( Overtime Hours × Basic Rate ) + ( Overtime Hours × Overtime Premium Rate ) \text{Total Overtime Pay} = (\text{Overtime Hours} \times \text{Basic Rate}) + (\text{Overtime Hours} \times \text{Overtime Premium Rate}) Total Overtime Pay = ( Overtime Hours × Basic Rate ) + ( Overtime Hours × Overtime Premium Rate ) Example: Standard rate = $12/hour. Overtime rate = Time-and-a-half ($18/hour).
For 1 hour of overtime:
- Basic wage element = $12.00
- Overtime premium element = $6.00 ($18.00 - $12.00)
- Accounting Classification of Overtime
The accounting treatment depends on the underlying reason why overtime was worked:
General / Routine Overtime (Normal Practice):
Circumstance: Overtime worked on a regular, recurring basis because the factory operates near capacity, or to meet general production schedules across all customer orders.
Treatment: The basic pay for all hours worked by direct workers is charged to Direct Labour (WIP Control) . The overtime premium is classified as an Indirect Cost and debited to the Production Overhead Control Account .
Rationale: It would be arbitrary and unfair to penalise a customer whose order happened to be produced on a Saturday shift by charging them an extra 50% labour cost, while a customer whose order ran on Tuesday morning paid standard rates. Overtime worked to maintain general factory output benefits the business as a whole, so the premium is shared across all output as an indirect production overhead.
Specific Customer Request Overtime:
Circumstance: Overtime worked at the express request of a specific customer who needs an urgent delivery expedited and has agreed to bear the enhanced labour rate.
Treatment: Both the basic pay AND the overtime premium are treated as Direct Labour and charged directly to that specific customer's job in the Work-in-Progress (WIP) Control Account .
Overtime Arising from Internal Operational Inefficiencies:
Circumstance: Overtime required because of machine breakdowns, material delays, or operational mismanagement earlier in the week.
Treatment: The overtime premium is debited to the Production Overhead Control Account (or written off directly to the Statement of Profit or Loss as an abnormal operating loss if severe).
Shift Premiums
A shift premium (or shift allowance) is an extra rate paid to workers to compensate for working unsociable hours (such as night shifts, rotating evening shifts, or weekend rosters). Like routine overtime premiums, shift allowances are classified as Indirect Production Overheads and debited to the Production Overhead Control Account, unless a specific customer contract explicitly required dedicated off-hours production.
Idle Time Accounting
Idle time is paid operational time during which employees are available to work but cannot produce output due to factors beyond their immediate control:
- Machine breakdowns or scheduled retooling delays
- Stockouts of raw materials or components
- Power outages or compressed air pressure failures
- Delays in receiving instructions or blueprints from supervisors
Accounting Treatment: Idle time wages are calculated as: Idle Hours × Basic Hourly Rate \text{Idle Hours} \times \text{Basic Hourly Rate} Idle Hours × Basic Hourly Rate .
Idle time pay is NEVER charged to Work-in-Progress (WIP) .
It is debited to an Idle Time Account , which is closed out into the Production Overhead Control Account (for normal, expected operational downtime) or charged directly to the Statement of Profit or Loss as an abnormal loss (for catastrophic, non-routine disruptions).
3. Systems to Record Labour Effort & Time Tracking
Organisations deploy distinct systems to capture labour attendance and measure specific task execution. Reconciling these records provides the data needed for payroll computation and cost control.
Attendance Recording vs. Activity Recording
Recording System Primary Purpose Common Instruments Typical Data Captured
Attendance Recording Establishes the total time an employee spends on site for payroll calculations (gross wages due). Electronic swipe cards, biometric scanners, optical turnstiles, digital clock cards. Clock-in time, clock-out time, meal break durations, total shift hours on site.
Activity (Job) Recording Tracks the specific jobs, batches, operations, or overhead tasks performed during the shift. Daily/weekly timesheets, job cards, route cards, piecework tickets, barcode scanners at work cells. Job number, machine operation code, units produced, setup hours, downtime codes.
Reconciling Attendance and Job Time: Detecting Idle Time
Attendance records measure the gross time paid , while job records measure the productive time utilized . Management accountants perform periodic reconciliations to isolate non-productive time: Total Attendance Hours (Clock Cards) − Total Productive Job Hours (Job Tickets) = Idle Time Hours \text{Total Attendance Hours (Clock Cards)} - \text{Total Productive Job Hours (Job Tickets)} = \text{Idle Time Hours} Total Attendance Hours (Clock Cards) − Total Productive Job Hours (Job Tickets) = Idle Time Hours
If clock cards show an employee was present and paid for 42 hours, but job tickets account for only 37.5 hours of productive work on customer orders, the difference of 4.5 hours represents unallocated idle time that must be investigated and charged to production overheads.
4. Labour Cost Accounting & Ledger Entries (Wages Control)
The Wages Control Account functions as a central clearing account through which all payroll transactions pass before being distributed to inventory or overhead ledgers.
The Sequence of Ledger Entries
Recording Gross Wages Earned & Payroll Deductions:
- Debit: Wages Control Account (Gross Wages)
- Credit: Bank Account (Net Wages paid to employees)
- Credit: PAYE / Income Tax Payable (Withholding tax due to tax authorities)
- Credit: Social Security / National Insurance Payable (Employee statutory contributions)
- Credit: Pension Contributions Payable (Employee pension deductions)
Recording Employer Payroll Taxes & Contributions:
- Debit: Wages Control Account (Employer pension contributions and social security taxes)
- Credit: Social Security / Pension Authorities Payable
Distributing Labour Costs to Functional Cost Ledgers:
Debit: Work-in-Progress (WIP) Control Account (Direct labour basic wages + customer-specific overtime)
Debit: Production Overhead Control Account (Indirect factory wages + normal overtime premiums + shift premiums + normal idle time)
- Debit: Administration Overhead Control Account (Executive, accounting, and HR salaries)
- Debit: Selling & Distribution Overhead Control Account (Sales commissions, showroom staff, delivery drivers)
- Credit: Wages Control Account (Clears the account to a zero balance) Wages Control Account

- Worked Example: Comprehensive Labour Cost Allocation
Scenario: Apex Engineering employs 5 direct machine operators and 2 factory maintenance technicians. During Week 24, payroll data reveals the following:
Standard contractual week: 40 hours per worker.
Basic hourly pay rate: $15.00 for direct operators; $18.00 for maintenance technicians.
Overtime rate: Time-and-a-half (1.5 × basic rate) for all weekend hours.
Actual hours worked in Week 24:
Direct operators: 230 hours total (200 standard hours + 30 overtime hours). Of the 30 overtime hours, 10 hours were worked at the specific urgent request of Customer Beta; the remaining 20 hours were worked to maintain general production schedules.
During the week, direct operators recorded 12 hours of idle time due to a central compressor breakdown.
Maintenance technicians: 90 hours total (80 standard hours + 10 general overtime hours). No idle time.
Step 1: Calculate Gross Wages for Direct Operators
Total hours = 230 hours.
Basic pay = 230 hours × $15.00 = $3,450.
Overtime premium = 30 overtime hours × ($15.00 × 0.5) = 30 × $7.50 = $225.
Gross wages for direct operators = $3,450 + $225 = $3,675 .
Step 2: Allocate Direct Operators' Pay
Specific Customer Overtime: Customer Beta requested 10 overtime hours. Both basic pay and premium are charged directly to WIP: Customer Beta WIP = 10 hours × $ 22.50 = $ 225.00 \text{Customer Beta WIP} = 10 \text{ hours} \times \$22.50 = \$225.00 Customer Beta WIP = 10 hours × $22.50 = $225.00
Idle Time: 12 hours debited to Production Overhead at basic rate: Idle Time Overhead = 12 hours × $ 15.00 = $ 180.00 \text{Idle Time Overhead} = 12 \text{ hours} \times \$15.00 = \$180.00 Idle Time Overhead = 12 hours × $15.00 = $180.00
General Overtime Premium: 20 hours debited to Production Overhead: General Overtime Premium = 20 hours × $ 7.50 = $ 150.00 \text{General Overtime Premium} = 20 \text{ hours} \times \$7.50 = \$150.00 General Overtime Premium = 20 hours × $7.50 = $150.00
Direct Productive Labour (General WIP):
Total hours paid = 230.
Less: Customer Beta overtime hours (10), Idle hours (12), leaving 208 general productive hours. General WIP Direct Labour = 208 hours × $ 15.00 = $ 3 , 120.00 \text{General WIP Direct Labour} = 208 \text{ hours} \times \$15.00 = \$3,120.00 General WIP Direct Labour = 208 hours × $15.00 = $3 , 120.00
Summary for Direct Operators:
- Total WIP Control = $3,120 + $225 = $3,345
- Total Production Overhead = $180 (idle time) + $150 (overtime premium) = $330
Check: $3,345 + $330 = $3,675.
Step 3: Calculate & Allocate Maintenance Technicians' Pay Maintenance technicians are indirect labour; all their remuneration is charged to Production Overhead.
Basic pay = 90 hours × $18.00 = $1,620.
Overtime premium = 10 hours × ($18.00 × 0.5) = 10 × $9.00 = $90.
Total Maintenance Pay = $1,620 + $90 = $1,710 (100% debited to Production Overhead Control).
- Step 4: Summary Journal Entry
- Debit: Work-in-Progress (WIP) Control Account = $3,345
- Debit: Production Overhead Control Account = $330 + $1,710 = $2,040
- Credit: Wages Control Account = $5,385
- 5. Labour Remuneration Systems
Remuneration methods govern how employee earnings are computed. Management must balance the goals of incentivising worker productivity against maintaining product quality and controlling unit costs.
1. Time-Based Wage Schemes
Under time-based systems (day-rate or hourly rate), earnings are tied directly to the duration of time spent on the employer's premises, irrespective of output volume. Total Earnings = Hours Worked × Rate per Hour \text{Total Earnings} = \text{Hours Worked} \times \text{Rate per Hour} Total Earnings = Hours Worked × Rate per Hour
Advantages: Simple to administer and understand; provides wage security for employees; avoids incentivising rushed work, which protects craftsmanship and quality.
Disadvantages: Provides no financial incentive to increase productivity or output; requires close and costly managerial supervision; direct labour costs per unit fluctuate with worker speed.
2. Piecework Schemes
Under piecework systems, earnings depend directly on the number of completed, acceptable units produced.
Straight Piecework
Workers are paid a uniform fixed rate for every unit completed: Total Earnings = Units Produced × Piece Rate per Unit \text{Total Earnings} = \text{Units Produced} \times \text{Piece Rate per Unit} Total Earnings = Units Produced × Piece Rate per Unit
Direct labour cost per unit remains perfectly constant, but output increases directly reduce fixed overhead per unit.
Differential Piecework Schemes
Taylor and Merrick introduced differential piecework schemes where the piece rate increases as production breaches specified volume thresholds. This heavily incentivises high performers:
- Units 1 to 80: $1.20 per unit
- Units 81 to 110: $1.50 per unit
- Units 111 and above: $1.90 per unit
- Piecework with a Guaranteed Minimum Wage
Pure piecework exposes workers to financial loss during machine breakdowns or material shortages. To comply with statutory national minimum wage legislation and preserve morale, employers implement a guaranteed day-rate safety net : Total Earnings = max ( Piecework Earnings , Guaranteed Minimum Time Wage ) \text{Total Earnings} = \max(\text{Piecework Earnings}, \text{Guaranteed Minimum Time Wage}) Total Earnings = max ( Piecework Earnings , Guaranteed Minimum Time Wage )
If a worker's piecework earnings fall below the contractual minimum, the employer pays the guaranteed minimum wage. The difference between the minimum wage paid and the piecework earned during downtime is treated as Idle Time (Production Overhead) .
3. Individual Incentive & Premium Bonus Schemes
Premium bonus schemes establish an allowed standard time for completing an operation. If an employee completes the task in less time, they receive their basic hourly wage for the actual hours worked, plus a financial bonus based on the time saved . Time Saved = Standard Time Allowed − Actual Time Taken \text{Time Saved} = \text{Standard Time Allowed} - \text{Actual Time Taken} Time Saved = Standard Time Allowed − Actual Time Taken
Two classical bonus schemes are tested in the ACCA syllabus:
The Halsey Premium Scheme
Developed by F.A. Halsey, this scheme awards the worker a fixed 50% of the time saved , paid at their basic hourly wage rate: Halsey Bonus = 0.50 × Time Saved × Basic Hourly Rate \text{Halsey Bonus} = 0.50 \times \text{Time Saved} \times \text{Basic Hourly Rate} Halsey Bonus = 0.50 × Time Saved × Basic Hourly Rate Total Halsey Earnings = ( Actual Time Taken × Hourly Rate ) + Halsey Bonus \text{Total Halsey Earnings} = (\text{Actual Time Taken} \times \text{Hourly Rate}) + \text{Halsey Bonus} Total Halsey Earnings = ( Actual Time Taken × Hourly Rate ) + Halsey Bonus
The Rowan Premium Scheme
Developed by James Rowan, this scheme calculates the bonus as the proportion of time saved relative to the standard time allowed, applied to the employee's basic pay for actual time taken: Rowan Bonus = ( Time Saved Standard Time Allowed ) × ( Actual Time Taken × Basic Hourly Rate ) \text{Rowan Bonus} = \left(\frac{\text{Time Saved}}{\text{Standard Time Allowed}}\right) \times (\text{Actual Time Taken} \times \text{Basic Hourly Rate}) Rowan Bonus = ( Standard Time Allowed Time Saved ) × ( Actual Time Taken × Basic Hourly Rate ) Total Rowan Earnings = ( Actual Time Taken × Hourly Rate ) + Rowan Bonus \text{Total Rowan Earnings} = (\text{Actual Time Taken} \times \text{Hourly Rate}) + \text{Rowan Bonus} Total Rowan Earnings = ( Actual Time Taken × Hourly Rate ) + Rowan Bonus
Comparative Analysis: Halsey vs. Rowan
Feature Halsey Scheme Rowan Scheme
Bonus Sharing Fixed 50/50 split between employee and employer Proportional sharing: ( Time Saved / Time Allowed ) (\text{Time Saved} / \text{Time Allowed}) ( Time Saved / Time Allowed )
Modest Time Savings (< 50%) Pays a smaller bonus than Rowan Pays a higher bonus than Halsey
Extreme Time Savings (> 50%) Bonus continues to increase linearly without limit Bonus percentage peaks and decreases; protects against loose standard times
Risk to Employer High cost if standard times are set too generously Natural ceiling on total payout; protects against inaccurate time-and-motion studies
Worked Example: Halsey vs. Rowan Bonus Calculation
Scenario: A machine operator has a basic rate of $16.00 per hour. The standard time allowed to produce one precision valve is 1.5 hours. In a 45-hour working week, the operator completes 40 precision valves.
Preliminary Data:
Actual time taken ( A A A ) = 45 hours.
Standard time allowed ( S S S ) = 40 units × 1.5 hours = 60 hours.
Time saved ( T s T_s T s ) = 60 hours - 45 hours = 15 hours.
Basic pay for actual hours = 45 hours × $16.00 = $720.00 .
Halsey Calculation: Bonus = 0.50 × 15 hours saved × $ 16.00 = $ 120.00 \text{Bonus} = 0.50 \times 15 \text{ hours saved} \times \$16.00 = \$120.00 Bonus = 0.50 × 15 hours saved × $16.00 = $120.00 Total Halsey Earnings = $ 720.00 + $ 120.00 = $ 840.00 \text{Total Halsey Earnings} = \$720.00 + \$120.00 = \mathbf{\$840.00} Total Halsey Earnings = $720.00 + $120.00 = $840.00 Effective Hourly Rate = $ 840.00 45 hours = $ 18.67 per hour \text{Effective Hourly Rate} = \frac{\$840.00}{45 \text{ hours}} = \mathbf{\$18.67 \text{ per hour}} Effective Hourly Rate = 45 hours $840.00 = $18.67 per hour
Rowan Calculation: Bonus = ( 15 hours saved 60 hours allowed ) × ( 45 hours × $ 16.00 ) = 0.25 × $ 720.00 = $ 180.00 \text{Bonus} = \left(\frac{15 \text{ hours saved}}{60 \text{ hours allowed}}\right) \times (45 \text{ hours} \times \$16.00) = 0.25 \times \$720.00 = \$180.00 Bonus = ( 60 hours allowed 15 hours saved ) × ( 45 hours × $16.00 ) = 0.25 × $720.00 = $180.00 Total Rowan Earnings = $ 720.00 + $ 180.00 = $ 900.00 \text{Total Rowan Earnings} = \$720.00 + \$180.00 = \mathbf{\$900.00} Total Rowan Earnings = $720.00 + $180.00 = $900.00 Effective Hourly Rate = $ 900.00 45 hours = $ 20.00 per hour \text{Effective Hourly Rate} = \frac{\$900.00}{45 \text{ hours}} = \mathbf{\$20.00 \text{ per hour}} Effective Hourly Rate = 45 hours $900.00 = $20.00 per hour
Notice: Because the time saved (15 hours) represents 25% of the time allowed (less than 50%), the Rowan scheme pays a higher bonus ($180 vs $120) than the Halsey scheme.
Group Bonus Schemes
In automated or team-based manufacturing cells, individual output cannot be isolated because workers are mutually dependent. Organisations use group bonus schemes where a collective bonus pool is calculated based on total group output, defect reduction, or team hours saved. The bonus pool is shared among team members in proportion to their basic pay, hours worked, or seniority.
Advantage: Promotes team cooperation, mutual assistance, and peer mentoring.
Disadvantage: Risk of the "free-rider" effect, where less productive workers benefit from the efforts of highly productive peers, leading to interpersonal friction.
6. Labour Turnover: Measurement, Costs & Causes
Labour turnover measures the proportion of an organisation's workforce that leaves and must be replaced during a specific accounting period.
Calculating the Labour Turnover Rate
The standard formula required by the ACCA syllabus is: Labour Turnover Rate = ( Number of Replacements Recruited Average Number of Employees in Period ) × 100 % \text{Labour Turnover Rate} = \left(\frac{\text{Number of Replacements Recruited}}{\text{Average Number of Employees in Period}}\right) \times 100\% Labour Turnover Rate = ( Average Number of Employees in Period Number of Replacements Recruited ) × 100%
Where: Average Number of Employees = Employees at Start of Period + Employees at End of Period 2 \text{Average Number of Employees} = \frac{\text{Employees at Start of Period} + \text{Employees at End of Period}}{2} Average Number of Employees = 2 Employees at Start of Period + Employees at End of Period
Warning
Critical ACCA Exam Trap: The numerator must contain the number of replacements actually recruited to fill vacancies left by leavers , NOT the total number of leavers! If 50 employees leave, but 20 positions are permanently eliminated due to automation or downsizing and only 30 replacements are hired, you must use 30 in the numerator. Redundancies are not turnover replacements.
Worked Example: Labour Turnover Calculation
Scenario: On 1 January 20X6, Orion Ltd employed 480 personnel. On 31 December 20X6, the workforce stood at 520 personnel. During the year, 65 employees left the company (35 resigned for higher pay, 15 retired, and 15 were made redundant following office automation). The company recruited 105 employees during the year. Of these, 42 were classified as replacements for leavers; the remaining 63 filled new posts created by expansion. The workforce therefore reconciles: 480 − 65 + 105 = 520 480 - 65 + 105 = 520 480 − 65 + 105 = 520 employees.
Step 1: Calculate Average Workforce Average Workforce = 480 + 520 2 = 500 employees \text{Average Workforce} = \frac{480 + 520}{2} = 500 \text{ employees} Average Workforce = 2 480 + 520 = 500 employees
- Step 2: Determine Replacements
- Total leavers = 65
- Redundancies = 15 (not replaced)
- Actual replacements recruited = 42
Step 3: Calculate Labour Turnover Rate Labour Turnover Rate = ( 42 500 ) × 100 % = 8.40 % \text{Labour Turnover Rate} = \left(\frac{42}{500}\right) \times 100\% = \mathbf{8.40\%} Labour Turnover Rate = ( 500 42 ) × 100% = 8.40%
(Note: 65 / 500 = 13.0 % 65/500 = 13.0\% 65/500 = 13.0% is the separation rate, not ACCA's replacement-based labour turnover rate. The required numerator is the 42 leavers whose positions were replaced.)
Costs of Labour Turnover
Management accountants divide turnover costs into two categories:
Preventative Costs: Expenditure incurred intentionally to keep staff satisfied, motivated, and engaged to prevent turnover:
- Providing competitive remuneration packages, pensions, and performance bonuses
- Ergonomic and safe working environments
- Staff training, personal development programs, and career progression planning
- Employee welfare amenities, medical coverage, and wellness initiatives
Replacement Costs: Costs incurred as a direct consequence of employees leaving and needing replacement:
- Advertising vacancies, agency finder fees, and interview management time
- Pre-employment background checks and induction training
- Learning curve inefficiencies and lower initial productivity of new hires
- Increased scrap, rework, and tool breakage during training periods
Machine downtime and lost sales while positions remain vacant Total Cost of Turnover = Preventative Costs + Replacement Costs \text{Total Cost of Turnover} = \text{Preventative Costs} + \text{Replacement Costs} Total Cost of Turnover = Preventative Costs + Replacement Costs
Optimal Policy: Management should invest in preventative measures up to the point where the marginal cost of prevention equals the marginal saving in replacement costs.
Causes of Labour Turnover
Avoidable Causes: Poor compensation, inadequate supervision, bullying or toxic culture, lack of training/advancement opportunities, unsafe conditions, and unreasonable workloads.
Unavoidable Causes: Retirement, critical illness or death, family relocation, and pregnancy or family caregiving obligations.
7. Labour Performance & Operating Ratios
Management accountants monitor labour force efficiency, capacity utilisation, and overall production volume using three interrelated standard hours ratios.
Definitions and Standard Hours
A standard hour is the hypothetical amount of work that an average, fully trained worker should complete in one hour when working at normal efficiency under standard operating conditions. Standard Hours for Actual Output = Actual Units Produced × Standard Time Allowed per Unit \text{Standard Hours for Actual Output} = \text{Actual Units Produced} \times \text{Standard Time Allowed per Unit} Standard Hours for Actual Output = Actual Units Produced × Standard Time Allowed per Unit
The Three Core Ratios
Efficiency (Productivity) Ratio: Measures whether the workforce completed the actual volume of production faster or slower than standard expected time. A ratio above 100% indicates superior efficiency (working faster than standard): Efficiency Ratio = ( Standard Hours for Actual Output Actual Hours Worked ) × 100 % \text{Efficiency Ratio} = \left(\frac{\text{Standard Hours for Actual Output}}{\text{Actual Hours Worked}}\right) \times 100\% Efficiency Ratio = ( Actual Hours Worked Standard Hours for Actual Output ) × 100%
Capacity (Utilisation) Ratio: Measures whether total hours worked were higher or lower than planned budgeted hours. It reflects overtime, absenteeism, and plant operating schedule variations. A ratio above 100% indicates the workforce worked more hours than budgeted: Capacity Ratio = ( Actual Hours Worked Budgeted Direct Labour Hours ) × 100 % \text{Capacity Ratio} = \left(\frac{\text{Actual Hours Worked}}{\text{Budgeted Direct Labour Hours}}\right) \times 100\% Capacity Ratio = ( Budgeted Direct Labour Hours Actual Hours Worked ) × 100%
Production Volume (Activity) Ratio: Measures overall output achieved (expressed in standard hours) relative to the original budgeted production commitment: Activity Ratio = ( Standard Hours for Actual Output Budgeted Direct Labour Hours ) × 100 % \text{Activity Ratio} = \left(\frac{\text{Standard Hours for Actual Output}}{\text{Budgeted Direct Labour Hours}}\right) \times 100\% Activity Ratio = ( Budgeted Direct Labour Hours Standard Hours for Actual Output ) × 100%
The Mathematical Identity
The three ratios are mathematically linked by a strict multiplicative relationship: Activity Ratio = Efficiency Ratio × Capacity Ratio \text{Activity Ratio} = \text{Efficiency Ratio} \times \text{Capacity Ratio} Activity Ratio = Efficiency Ratio × Capacity Ratio Standard Hours Budgeted Hours = ( Standard Hours Actual Hours ) × ( Actual Hours Budgeted Hours ) \frac{\text{Standard Hours}}{\text{Budgeted Hours}} = \left(\frac{\text{Standard Hours}}{\text{Actual Hours}}\right) \times \left(\frac{\text{Actual Hours}}{\text{Budgeted Hours}}\right) Budgeted Hours Standard Hours = ( Actual Hours Standard Hours ) × ( Budgeted Hours Actual Hours )
(When using percentages: Activity Ratio % = (Efficiency % × Capacity %) / 100).
Worked Example: Comprehensive Labour Performance Ratios
Scenario: Zenith Manufacturing prepares an annual operational budget for Department Q:
- Budgeted monthly production = 2,500 units
- Standard labour time allowed per unit = 3.0 direct labour hours
- Budgeted direct labour hours = 2,500 units × 3.0 hours = 7,500 hours
Actual operational results for March:
- Actual production achieved = 2,700 units
- Actual direct labour hours worked = 7,776 hours
Step 1: Calculate Standard Hours for Actual Output Standard Hours = 2 , 700 units × 3.0 hours = 8 , 100 standard hours \text{Standard Hours} = 2,700 \text{ units} \times 3.0 \text{ hours} = \mathbf{8,100 \text{ standard hours}} Standard Hours = 2 , 700 units × 3.0 hours = 8 , 100 standard hours
Step 2: Calculate Efficiency Ratio Efficiency Ratio = ( 8 , 100 standard hours 7 , 776 actual hours ) × 100 % = 104.167 % \text{Efficiency Ratio} = \left(\frac{8,100 \text{ standard hours}}{7,776 \text{ actual hours}}\right) \times 100\% = \mathbf{104.167\%} Efficiency Ratio = ( 7 , 776 actual hours 8 , 100 standard hours ) × 100% = 104.167%
Interpretation: Workers took 7,776 hours to complete 8,100 hours of standard work. They were ~4.17% more efficient than standard.
Step 3: Calculate Capacity Ratio Capacity Ratio = ( 7 , 776 actual hours 7 , 500 budgeted hours ) × 100 % = 103.680 % \text{Capacity Ratio} = \left(\frac{7,776 \text{ actual hours}}{7,500 \text{ budgeted hours}}\right) \times 100\% = \mathbf{103.680\%} Capacity Ratio = ( 7 , 500 budgeted hours 7 , 776 actual hours ) × 100% = 103.680%
Interpretation: The department worked 276 hours more than budgeted (e.g. through overtime or lower absenteeism), operating at 103.68% of budgeted capacity.
Step 4: Calculate Activity (Production Volume) Ratio Activity Ratio = ( 8 , 100 standard hours 7 , 500 budgeted hours ) × 100 % = 108.000 % \text{Activity Ratio} = \left(\frac{8,100 \text{ standard hours}}{7,500 \text{ budgeted hours}}\right) \times 100\% = \mathbf{108.000\%} Activity Ratio = ( 7 , 500 budgeted hours 8 , 100 standard hours ) × 100% = 108.000%
Interpretation: Overall production output was 8% above the original budget target.
Step 5: Verify the Multiplicative Check Activity Ratio = 104.167 % × 103.680 % 100 = 10 , 800 100 = 108.000 % \text{Activity Ratio} = \frac{104.167\% \times 103.680\%}{100} = \frac{10,800}{100} = \mathbf{108.000\%} Activity Ratio = 100 104.167% × 103.680% = 100 10 , 800 = 108.000%
The identity holds true.
