The return on capital employed formula
Return on capital employed is EBIT divided by capital employed: return on capital employed = EBIT ÷ capital employed × 100. EBIT is earnings before interest and tax — the operating profit. Capital employed is total assets minus current liabilities — the long-term money tied up in the business: the equity plus the long-term borrowing. The answer is a percentage: 20.00% means each dollar of capital employed generates 20 cents of operating profit in the year. Try the numbers on the return on capital employed calculator and it does the division for you.
Step 1: find the EBIT and the capital employed
Start with the income statement. EBIT sits near the bottom of the trading account — the operating profit after the cost of sales and the running costs, before interest and tax are taken off. Then find the capital employed on the balance sheet — total assets minus current liabilities. Total assets are everything the business owns, less the bills due within the year. If the balance sheet shows total assets of $2,000,000 and current liabilities of $800,000, the capital employed is $1,200,000. Use the same year for both numbers: a year of profit against a year of capital.
Step 2: work out the return
Divide the EBIT by the capital employed and multiply by 100. Here is the worked example: $240,000 of EBIT divided by $1,200,000 of capital employed is 20.00%. The arithmetic is $240,000 ÷ $1,200,000 × 100 = 20.00, so each dollar of capital employed generates $0.20 of operating profit. The answer is a percentage, not a multiple.
Step 3: check the result against what is normal
A return of 20.00% means the business turns each dollar of long-term money into 20 cents of operating profit a year. Whether that is good depends on the industry: a return above 15% is generally seen as strong, 10–15% is middling, and below 10% is weak — but the bar moves. Capital-heavy businesses such as utilities and airlines run lower; asset-light businesses such as software run higher. A 20.00% return sits above the strong line. Compare within the same industry, never across industries.
Three worked examples
Example one — the headline numbers. A business has $240,000 of EBIT and $1,200,000 of capital employed. The return is $240,000 ÷ $1,200,000 × 100 = 20.00%. Each dollar of capital employed generates $0.20 of operating profit.
Example two — averaging the capital employed. A business began the year with $1,100,000 of capital employed and ended it with $1,300,000. The average capital employed is ($1,100,000 + $1,300,000) ÷ 2 = $1,200,000. With $240,000 of EBIT, the return is $240,000 ÷ $1,200,000 × 100 = 20.00%.
Example three — how much profit must I make? A business has $1,200,000 of capital employed and wants a 25.00% return. The EBIT needed is 25.00% × $1,200,000 = $300,000.00 — the profit target on the long-term money it already holds.
One reverse to check your answer
Work the numbers backwards to check them. A business has $1,200,000 of capital employed and wants a 22.50% return. The smallest whole-dollar EBIT for the return to reach 22.50% is $270,000 — $270,000 ÷ $1,200,000 × 100 = 22.50%, exactly. A dollar less, and the return falls short of the line. The return on capital employed calculator runs the reverses for you.
Why average capital employed, not ending capital employed
The denominator is the average of the beginning and ending capital employed, not the ending balance alone. The reason is timing: profits accrue through the year while the balance sheet is a snapshot. A business that buys a machine in December shows a fat capital employed at year end and a thin one in January. Averaging the two ends of the year smooths the timing out.
What a high return means
A high return means the business generates a lot of operating profit from a little long-term money: prices that hold, costs under control, assets that work hard. But it is not always good. It can come from a business that owns almost nothing and rents everything, so the denominator is small. A return that climbs because the business stopped investing is a warning, not a win.
What a low return means
A low return means the business generates little operating profit from a lot of long-term money: heavy plant, slow stock, receivables unpaid for months. But it is not always bad. A business investing heavily for future growth looks inefficient on paper until the investment pays off. A business that just launched a new line will look weak for a year or two, then the sales catch up.
Return on capital employed vs return on assets
Return on capital employed and return on assets measure the same idea on different denominators. Return on assets divides EBIT by ALL assets — everything the business owns, including the current assets. Return on capital employed divides EBIT by capital employed only — total assets minus current liabilities. The same business shows both numbers at once: with $240,000 of EBIT, $2,000,000 of total assets and $1,200,000 of capital employed, the return on assets is 12.00% and the return on capital employed is 20.00%. The gap is the current liabilities: the short-term bills that fund part of the assets without counting as long-term money. Use the return on assets calculator for the whole balance sheet, and read the guide to return on equity for the shareholder side.
What to do when the return is low
Three moves lift a low return. Raise the operating profit — higher prices where the market allows, lower costs where the waste sits. Use the capital better — sell idle assets, collect receivables faster, hold less stock. And avoid over-investing in low-return projects — a new machine that earns less than the money costs drags the return down.
How return on capital employed differs from margin
Return on capital employed is not profitability per sale. Margin is profit per dollar of sales; return on capital employed is profit per dollar of capital. A supermarket has a tiny margin and a modest return; a software firm has a fat margin and a high return. Both can be fine businesses — they just make their money in different ways. Never judge a business on the return alone: pair it with the margin.
