Labour Efficiency, Productivity and Employee Cost Reporting

Updated 4 October 2026 · Fact-checked

Labour efficiency measures how well workers use time compared with a standard. Productivity measures output per unit of labour input. You solve questions by finding standard hours for actual output, comparing with actual hours and available hours, then applying the ratio formulas and interpreting the result.

Understand Labour Efficiency, Productivity and Employee Cost Reporting

Labour cost is not only about what you pay. It is also about what you get for it. Two factories can pay the same wages and still have very different costs per unit, because workers produce different amounts in the same time. Efficiency and productivity measures show this gap.

Labour efficiency compares the standard time allowed for the actual output with the actual time taken. If workers produce 500 units that should take 400 standard hours and they take 500 hours, they are working below standard. Activity ratios (efficiency, capacity utilisation and activity) compare hours or output against a budget or standard. Labour productivity is a broader idea: output per worker, per hour or per rupee of labour cost.

Four personnel and work-study tools sit beside these measures. Job evaluation rates the job, not the person. It decides the relative worth of jobs so that a fair wage structure can be set. Merit rating rates the person. It assesses how well an employee performs on the job, and is used for increments, promotions and bonus.

Time study measures how long a job should take by observing and timing the work, then adding allowances to get a standard time. Motion study studies the movements of the worker and machine to remove wasteful ones and find the best method. Motion study usually comes first to fix the method. Time study then sets the time for that method.

Key rules to remember

Efficiency ratio: Efficiency ratio = Standard hours for actual output ÷ Actual hours worked × 100; Above 100% means workers took less time than standard.
Capacity utilisation ratio: Capacity utilisation ratio = Actual hours worked ÷ Budgeted hours × 100; Shows how much of the planned hours were actually worked.
Activity ratio: Activity ratio = Standard hours for actual output ÷ Budgeted hours × 100; Compares actual output, in standard hours, with the budgeted output.
Link between the three: Activity ratio = Efficiency ratio × Capacity utilisation ratio ÷ 100; Use it to find a missing ratio. In decimals: Activity = Efficiency × Capacity utilisation.
Labour productivity: Productivity = Output ÷ Labour input (hours, workers or labour cost); Choose the input the question names. State the unit in your answer.
Standard time: Standard time = Basic (normal) time + Allowances; Basic time = Observed time × Rating ÷ 100. Allowances cover fatigue, personal needs and delays.

How to solve Labour Efficiency, Productivity and Employee Cost Reporting questions

Use this order for any numerical or theory question on this topic.

1Identify what is asked: a ratio, a productivity figure, or a theory distinction.
2List the data: output, standard time per unit, actual hours, budgeted hours.
3Compute standard hours for actual output = Actual output × Standard hours per unit.
4Apply the formula: efficiency uses actual hours, capacity uses budgeted hours, activity uses standard hours over budgeted hours.
5Check with Activity = Efficiency × Capacity utilisation.
6Give each answer as a percentage, and say if it is above or below 100%.
7For theory, state the object rated (job or person), the purpose and the use, then give an example.

Quickest way: Three hour figures, three ratios

When to use it: Use this in the MCQ section and as the first line of any written ratio answer.

Write three numbers in a row: Standard hours for actual output (S), Actual hours (A), Budgeted hours (B).
Efficiency = S ÷ A. Capacity = A ÷ B. Activity = S ÷ B.
The common term A or S cancels, so Activity always equals Efficiency × Capacity.
In MCQs, eliminate options where activity is not the product of the other two.
In written answers, show S, A and B first. Step marks go to the working, then the interpretation.

Common mistakes in Labour Efficiency, Productivity and Employee Cost Reporting

Using budgeted hours in the efficiency ratio.
All three ratios look alike and the denominators get mixed up.
Fix: Efficiency compares standard hours with actual hours. Budgeted hours appear only in capacity and activity.
Taking standard hours as hours per unit without multiplying by actual output.
The question gives the time per unit, and students use it directly.
Fix: Always find standard hours for actual output = units produced × standard hours per unit.
Saying job evaluation rates employees.
Both techniques sound like rating people.
Fix: Job evaluation rates the job. Merit rating rates the person doing it.
Treating time study and motion study as the same.
Both are part of work study.
Fix: Motion study improves the method by removing wasteful movements. Time study sets the time for the chosen method.
Forgetting allowances when finding standard time.
Students stop at observed time or basic time.
Fix: Add allowances to basic time. Apply the rating factor to observed time before that.
Not interpreting the ratio.
Students stop once the percentage is calculated.
Fix: Add one line: above 100% is favourable, below 100% is adverse, with a likely reason.

Worked examples

Example 1

A department has budgeted 2,000 hours for the month. Standard time is 4 hours per unit. Actual output is 450 units and actual hours worked are 1,800. Calculate the efficiency ratio, capacity utilisation ratio and activity ratio.

Show the solution

Standard hours for actual output = 450 × 4 = 1,800 hours.
Efficiency ratio = 1,800 ÷ 1,800 × 100 = 100%.
Capacity utilisation ratio = 1,800 ÷ 2,000 × 100 = 90%.
Activity ratio = 1,800 ÷ 2,000 × 100 = 90%.
Check: 100% × 90% = 90%.

Answer: Efficiency ratio 100%, capacity utilisation ratio 90%, activity ratio 90%. Workers are exactly on standard, but 10% of budgeted hours were not used.

Example 2

Budgeted hours are 1,000. Actual hours are 1,100. Standard hours for actual output are 990. Find the three ratios and comment.

Show the solution

Efficiency ratio = 990 ÷ 1,100 × 100 = 90%.
Capacity utilisation ratio = 1,100 ÷ 1,000 × 100 = 110%.
Activity ratio = 990 ÷ 1,000 × 100 = 99%.
Check: 0.90 × 1.10 = 0.99, which is 99%.

Answer: Efficiency 90%, capacity utilisation 110%, activity 99%. Workers used more hours than planned but were slow, so output was 1% below the budget.

Exam tips

Short notes and difference questions often ask for job evaluation versus merit rating. Answer in a two-column style with points on object, purpose, basis, and use.
In numericals, show standard hours, actual hours and budgeted hours as the first working lines.
For time and motion study, link them: motion study fixes the method, time study sets the time.
In MCQs, check whether the question asks for a ratio or a variance. The two topics are related but the formulas differ.
Write one line of interpretation after each ratio. Examiners often reward it.

Labour Efficiency, Productivity and Employee Cost Reporting: frequently asked questions

What is the difference between job evaluation and merit rating?

Job evaluation rates the job to decide its relative worth and set a wage structure. Merit rating rates the individual employee's performance on the job. Job evaluation is used for basic pay grades. Merit rating is used for increments, promotion and bonus.

What is the difference between time study and motion study?

Time study measures the time a job should take, with rating and allowances. Motion study examines the movements involved to find the easiest and least wasteful method. Motion study is done first, then time study sets the standard time.

How are efficiency, capacity utilisation and activity ratios related?

Activity ratio equals efficiency ratio multiplied by capacity utilisation ratio, when each is taken as a decimal or divided by 100. This lets you find a missing ratio from the other two.

What are common measures of labour productivity?

Common measures are output per labour hour, output per worker and output per rupee of labour cost. Use the measure that matches the data in the question and state the unit of your answer.
