ROIC
Return on invested capital — efficiency of the capital base
ROIC asks how much after-tax operating profit the business earns on the capital tied up to run it. Higher durable ROIC often supports compounding — if reinvestment opportunities exist.
What it is
A common teaching form: ROIC = NOPAT ÷ invested capital.
NOPAT is operating profit after tax. Invested capital is the capital required to operate (definitions vary by data provider).
ROIC is about capital efficiency, not stock cheapness. A high-ROIC business can still be priced aggressively.
Interactive lab: NOPAT ÷ invested capital
Change profit or capital and watch efficiency respond. Same profit on less capital raises ROIC; bloated capital lowers it.
What the result means
ROIC rises when NOPAT rises or when invested capital falls (all else equal).
Compare ROIC to your required return mindset: earning above the opportunity cost of capital is the economic idea behind value creation — still separate from today’s market price.
One-year ROIC can be noisy. Durability matters more than a single snapshot.
ROIC vs growth
High ROIC with no reinvestment runway may return cash but grow slowly. High growth with low ROIC can destroy value if returns stay below the cost of capital.
The Discount Rate / DCF lesson connects required return to present value; ROIC helps you think about whether reinvestment is economically attractive.

Extreme efficiency figures are possible for asset-light models, but definitions and one-offs can exaggerate the ratio. Use ROIC as a quality lens, then verify cash conversion.

- Comparing ROIC across providers without matching definitions of invested capital.
- Treating a high ROIC print as proof the stock is a buy.
- Ignoring how goodwill, leases, and buybacks distort capital bases.
- Confusing ROIC with ROE (leverage can inflate ROE).
