Divisional Performance Measurement: formula sheet
Key formulas
- Cost centre measure
- Variance = Actual cost − Budgeted (standard) cost for actual output
- Used for cost centres. Compare on a flexed basis where output differs from budget.
- Profit centre measure
- Divisional profit = Divisional revenue − Divisional costs
- Check which costs the manager controls before judging the manager.
- Investment centre measure (link)
- Return on capital employed = Divisional profit ÷ Capital employed × 100
- Basic form of ROI. Detailed treatment sits in the ROI and Residual Income topics.
- Controllability rule
- Manager performance = Results from controllable items only
- Division performance (as an investment) may include non-controllable items; manager performance should not.
- Return on Investment
- ROI = (Divisional profit ÷ Capital employed) × 100
- Use the profit and capital definition given in the question. If none is given, state your assumption.
- Profit margin
- Profit margin = (Divisional profit ÷ Sales) × 100
- Uses the same profit figure as in ROI.
- Capital turnover
- Capital turnover = Sales ÷ Capital employed
- Expressed in times. Uses the same capital figure as in ROI.
- DuPont breakdown
- ROI = Profit margin × Capital turnover = (Profit ÷ Sales) × (Sales ÷ Capital employed)
- Sales cancels out. Use it to check your answer.
- Capital employed (asset approach)
- Capital employed = Fixed assets + Current assets − Current liabilities
- Equals net assets. Check whether the question wants total assets instead.
- Average capital employed
- Average capital employed = (Opening + Closing) ÷ 2
- Use only if the question asks for it or gives both figures.
- Residual income
- RI = Divisional profit − (Capital employed × Required rate of return)
- Use the profit measure the question gives. The product in brackets is the capital charge.
- Capital charge
- Capital charge = Capital employed × Required rate of return
- Use the capital figure stated in the question, such as opening, closing or average.
- Return on investment
- ROI = (Divisional profit ÷ Capital employed) × 100
- Compare with the required rate to judge the division.
- Decision rule
- Accept a project or division if RI > 0
- Equivalent to ROI of the project exceeding the required rate of return.
- EVA
- EVA = NOPAT − Capital charge
- Positive EVA means value creation; negative means value erosion.
- NOPAT
- NOPAT = EBIT × (1 − tax rate)
- EBIT is operating profit before interest. Do not deduct interest again.
- Capital charge
- Capital charge = WACC × Capital employed
- Use the capital employed the question specifies, opening or average, and adjust it if profit is adjusted.
- WACC
- WACC = (E ÷ V) × Ke + (D ÷ V) × Kd × (1 − t)
- E and D are equity and debt, V = E + D. Kd is the pre-tax cost of debt. Use market or stated weights as the question directs.
- Alternative EVA form
- EVA = (ROCE after tax − WACC) × Capital employed
- ROCE after tax = NOPAT ÷ Capital employed. Useful as a quick check.
- Minimum transfer price (seller)
- Minimum price = Variable (marginal) cost per unit + Opportunity cost per unit
- Opportunity cost is the contribution the seller loses by selling internally. It is nil if the seller has spare capacity.
- Opportunity cost with full capacity
- Opportunity cost = Contribution lost per unit on the external sale given up
- So, with no spare capacity and a market for all output, minimum price = external selling price less any cost saved on internal sales.
- Maximum transfer price (buyer)
- Maximum price = Lower of (net realisable value to the buyer, external purchase price of the same input)
- Net realisable value = buyer's selling price less its further processing costs, other than the transferred input.
- Acceptable negotiation range
- Minimum price ≤ Transfer price ≤ Maximum price
- If the minimum exceeds the maximum, the transfer should not happen from the company's viewpoint.
- Cost plus price
- Transfer price = Cost per unit + Mark-up
- Cost may be variable, full or standard. State which basis you use.
- Market price less savings
- Transfer price = Market price − Costs saved on internal sale
- Savings include selling expenses, bad debts and packing the seller avoids.
- Four perspectives
- Financial + Customer + Internal business process + Learning and growth
- Learn the four names in this order. Always give at least one measure under each.
- Cause-and-effect chain
- Learning and growth → Internal process → Customer → Financial
- Use this to show how strategy links to results. Lower perspectives drive the upper ones.
- Scorecard structure
- Objective → Measure → Target → Action (initiative)
- Each perspective is built from these four columns.
- Customer retention rate
- Customers retained ÷ Customers at start of period × 100
- Count only existing customers at the start. Exclude new customers gained in the period.
- Defect rate
- Defective units ÷ Total units produced × 100
- A process measure. Lower is better.
Quick revision
- ROI = Profit ÷ Capital employed × 100; state which profit and capital you use.
- RI = Divisional profit − (Capital employed × Required rate of return).
- A positive RI means the division earns more than the required return.
- ROI can make a manager reject a project that is above the cost of capital but below current ROI.
- RI favours accepting any project earning more than the required rate, so it aligns better with company interest.
- EVA = Net operating profit after tax − (Capital employed × Cost of capital).
- EVA uses adjusted figures, for example treating some spending as investment, so it is closer to economic profit.
- Transfer price should motivate divisions toward decisions good for the whole company.
- With spare capacity, the minimum transfer price is the selling division's marginal cost; without it, add the opportunity cost.
- Market price is a good transfer price when an active external market exists.
- The balanced scorecard has four perspectives: financial, customer, internal business process, and learning and growth.
- Use controllable profit to judge the manager and a fuller profit to judge the division.
Common mistakes
- Calling any department with a budget a profit centre. Fix: A profit centre needs control over both revenue and costs. Apply the control test first.
- Treating division performance and manager performance as the same. Fix: State clearly that the manager is judged on controllable items only, while the division's economic viability is judged on full traceable results.
- Using different profit or capital definitions in margin, turnover and ROI. Fix: Decide profit and capital once at the start and use them in all three ratios. Margin × turnover must equal ROI.
- Forgetting to deduct current liabilities when finding capital employed. Fix: Read the question for the capital definition. If capital employed means net assets, use fixed assets plus current assets minus current liabilities.
- Subtracting the required rate percentage from ROI and calling it RI. Fix: RI is always in rupees. Convert the rate into a capital charge and subtract it from profit.
- Using the wrong capital figure, such as closing capital when average is asked. Fix: Underline the capital basis in the question before calculating.
- Deducting interest before finding NOPAT Fix: Start from operating profit (EBIT). The cost of debt is already inside WACC, so deducting interest double counts it.
- Using pre-tax cost of debt in WACC Fix: Always use Kd × (1 − t) for debt unless the question says the given cost is already after tax.
- Using full cost as the minimum price when the seller has spare capacity. Fix: With spare capacity, fixed cost is incurred whether or not the transfer happens. The minimum is variable cost only.
- Ignoring opportunity cost when the seller is at full capacity. Fix: Always ask whether each internal unit displaces an external sale. If yes, add the lost contribution.
Exam tips
- Section A often tests classification of centres: apply the control test (costs, revenue, investment) and you can answer in seconds.
- In descriptive answers, give balanced points with a one-line reason each. Marks go to explained points, not headings.
- Always say that managers should be judged on controllable items; this single line is often what examiners look for.
- If a case gives figures, link the topic to the right measure (cost variance, profit, ROI or Residual Income) and state your choice before calculating.
- Quote the formula first, then substitute. Even if arithmetic slips, you still earn method marks.
- In MCQs, check which profit and which capital base the options assume. Wrong options often come from using the other base.
- For theory questions on limitations, always include the dysfunctional decision example with numbers if you can.
- When asked to compare divisions, give the ranking and one reason using margin or turnover, not only ROI.
