What it measures
Return on invested capital is the after-tax operating profit a company earns for every dollar of capital put into the business, from both shareholders and lenders.
ROIC = net operating profit after tax (NOPAT) / (debt + equity - excess cash)
A company with 20% ROIC turns $100 of invested capital into $20 of yearly operating profit.
Why it matters
Growth only creates value when the money reinvested earns more than it costs. The cost of capital for most companies is around 8 to 10% a year.
- ROIC well above the cost of capital: every dollar reinvested creates value. Growth is good.
- ROIC near the cost of capital: growth adds size, not value.
- ROIC below it: growth destroys value.
A high ROIC sustained for many years is one of the strongest signs of an economic moat. Without a moat, competitors would copy the business and push returns down.
ROIC versus ROE
Return on equity (net income / shareholders' equity) is easier to find but can be flattered by debt: a company that borrows heavily and buys back shares shrinks its equity and inflates ROE. ROIC counts debt as invested capital too, so it is harder to game. See Debt-to-equity ratio.
Readings
| ROIC | Reading |
|---|---|
| Above 20% | Exceptional |
| 15% to 20% | Strong |
| 8% to 15% | Around the cost of capital |
| Below 8% | Weak |
Caveats
- Large acquisitions add goodwill to invested capital and lower ROIC for years.
- Asset-light businesses (software) naturally show high ROIC; compare within an industry.
- Definitions vary between data providers.
