ROIC (return on invested capital) measures how much a company earns for every dollar of capital it actually puts to work in the business. It is the best antidote to an inflated ROE: where ROE is fooled by buybacks, ROIC isn't.
How it's calculated
ROIC divides after-tax operating profit by invested capital:
- ROIC = Operating profit × (1 − tax rate) ÷ Invested capital × 100
- Invested capital = Financial debt + Equity − Cash
The logic of the denominator is the key: you add up all the money funding the business, whether it came from shareholders or from lenders, and subtract idle cash, because money parked at the bank isn't producing anything. What's left is the capital the company actually has working. And the numerator uses operating profit, before interest, because the point is to measure the business, not how it is financed.
The difference with ROE is in the denominator
ROE divides profit by shareholders' equity. ROIC divides it by all the capital employed. It sounds like a technical nuance, but it changes the answer completely when a company buys back stock aggressively.
When shares are repurchased and retired, book equity falls. Profit is unchanged, but the denominator of ROE shrinks, so the ratio rises. Nothing about the business has improved: it's pure arithmetic. Because ROIC doesn't use equity as its denominator but total capital employed, that effect disappears.
The example that makes it obvious
These are real figures from our coverage, computed from the reports each company files with the SEC. Look at the distance between the two columns:
- Las Vegas Sands: 154% ROE against a 19% ROIC.
- Kimberly-Clark: 118% ROE against a 21% ROIC.
- Home Depot: 101% ROE against a 25% ROIC.
- Mastercard: 232% ROE against an 89% ROIC.
A 154% ROE sounds like a once-in-a-generation business. A 19% ROIC sounds like a good, ordinary company. The second figure describes the business; the first mostly describes the balance sheet. Careful with the easy reading, though: an inflated ROE does not mean the company is bad, nor that buybacks are a swindle — they are often a sound way to return cash to shareholders. What it means is that this ROE can't be used to compare the quality of two businesses.
Mastercard is interesting precisely because, even corrected, its 89% ROIC is still extraordinary. There, buybacks inflate a figure that was outstanding to begin with.
What counts as a good ROIC
A ROIC sustained above 15% usually betrays a real competitive advantage: a brand, a network, a position rivals can't copy cheaply. Above 20%, an excellent business. But the benchmark that really matters isn't a round number — it's the cost of capital: a company earning 6% on the capital it employs, when that capital costs it 8%, is destroying value even though the income statement shows a profit. Growing like that means getting bigger and poorer at once.
As with every ratio, consistency matters more than the peak. A high ROIC over five or ten years says far more than an exceptional one in a single year.
When ROIC doesn't work
It isn't a universal metric, and it's worth knowing where it breaks down:
- Banks and insurers: their debt doesn't fund the business, it is the business. "Invested capital" loses its meaning and they have to be judged on other metrics.
- Deeply negative equity: when a company has bought back so much stock that its invested capital is near zero, the ratio explodes into absurd figures. That's broken arithmetic, not profitability — which is why we would rather show no figure than a meaningless one.
- Loss-making companies: with no positive operating profit, ROIC tells you nothing useful.
How to use it well
The most useful way to read ROIC is alongside ROE, not instead of it. If the two are close, the returns are clean and come from the business. If ROE doubles or triples ROIC, you know the gap is explained by buybacks or debt — and that the number to use when comparing against other companies is the second one.
