Plain definition
Return on capital employed (ROCE) divides earnings before interest and tax (EBIT) by average capital employed. It measures operating profit against the longer-term capital supporting the business, before the split between lenders and owners.
A common capital-employed definition is total assets less current liabilities, equivalent to equity plus non-current liabilities. Other definitions exist; they can treat cash and financing differently. Choose one and use it consistently.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
A manufacturer earns EBIT of on average capital employed of , giving ROCE of 20%. After a plant expansion, average capital employed reaches while EBIT initially remains . ROCE falls to 15%.
To restore 20% on that capital base, EBIT would need to reach . Management can now ask whether the expansion plan credibly produces the additional , and how long the ramp-up will take.
Why it matters
ROCE makes the capital cost of growth visible: higher sales alone may not justify a larger asset base. It is an accounting return, however, and can be affected by depreciation and asset age. A pre-tax ROCE should not be compared directly with an after-tax financing hurdle.
Practical consequence
Document the capital definition and average, then explain earnings and capital movements separately. Compare returns on a consistent tax and risk basis. For a new project, assess timed cash flows and net present value as well as its effect on reported ROCE.
