What Is ROIC and How Do You Calculate It?
ROIC, return on invested capital, is a company's after-tax operating profit divided by the capital invested in running the business. It shows how many cents of profit each dollar of capital earns, whoever supplied the dollar, lenders or shareholders.
That is why it beats ROE for comparing businesses: Altria's ROE is about 150%, but its ROIC on this site's data is about 59%. The gap is financing, not performance.
How do you calculate ROIC step by step?
The formula is ROIC = NOPAT ÷ invested capital, where NOPAT is net operating profit after tax.
- Find operating profit. Take operating profit (EBIT) from the income statement. It is profit before interest and tax, so it is the same whether the company is funded by debt or equity.
- Tax it to get NOPAT. Multiply operating profit by one minus the tax rate. NOPAT is the profit the business would earn with no debt. The worked examples here use a flat 21% US rate.
- Add up invested capital. Add operating working capital and net property, plant and equipment. For a full-cost view, add goodwill and acquired intangibles. Leave out cash, which does not run the business.
- Divide and compare. Divide NOPAT by invested capital. Compare the result across several years and with the company's cost of capital, since a return below that cost does not pay for the money invested.
Analysts also build invested capital from the other side, as debt plus equity minus cash. See the discount rate for the hurdle a return is compared with.
What does ROIC look like for real companies?
Using the capital figures this site takes from each company's latest 10-K, for the capital-light analysis, the full-cost version gives:
| Company | Operating profit | NOPAT (21% tax) | Invested capital | ROIC | ROE |
|---|---|---|---|---|---|
| Altria (MO) | $9.9B | $7.8B | $13.2B | 59% | 150% |
| AutoZone (AZO) | $3.6B | $2.9B | $6.3B | 45% | 249% |
| Coca-Cola (KO) | $13.8B | $10.9B | $24.6B | 44% | 43% |
| Kimberly-Clark (KMB) | $2.4B | $1.9B | $7.0B | 26% | 123% |
| Home Depot (HD) | $20.9B | $16.5B | $72.4B | 23% | 103% |
| Procter & Gamble (PG) | $19.7B | $15.6B | $87.1B | 18% | 30% |
| Exxon Mobil (XOM) | $41.9B | $33.1B | $311.0B | 11% | 13% |
| AT&T (T) | $24.2B | $19.1B | $184.5B | 10% | 12% |
Operating profit and capital are from the filings in this site's capital-efficiency data (fiscal years ended between August 2025 and June 2026). ROE is the trailing figure in the screener data, as of October 24, 2026. The 21% rate is an assumption, so treat the ROIC column as an estimate.
ROIC (after tax, full-cost capital) against trailing ROE. Where debt and buybacks have shrunk equity, ROE runs far above ROIC; where equity is large, the two nearly agree.
How does ROIC differ from ROE and ROA?
| Measure | Numerator | Denominator | What distorts it |
|---|---|---|---|
| ROIC | Operating profit after tax | Invested capital (working capital, equipment, optionally goodwill) | The tax rate used and how capital is counted |
| ROE | Net income | Shareholders' equity | Debt and buybacks, which shrink equity (see ROE) |
| ROA | Net income | Total assets | Cash and other non-operating assets in the denominator |
AutoZone shows the problem with ROE: 249%, against a 45% ROIC. Years of buybacks left little equity, so a modest profit looks enormous on it. The same thing shows in price-to-book, where equity is the denominator too.
How does ROIC connect to the capital-light test?
The capital-light analysis uses the same ingredients: operating profit, operating working capital and net property, plant and equipment, with goodwill in the full-cost view. Instead of a one-year level it asks how much capital a company added for each dollar of profit it added over 10 and 15 years, as in the See's Candies test. The method page gives the exact definition.
A high ROIC says the existing capital earns a lot. A low capital-per-dollar-of-profit ratio says growth did not need much more. The two usually travel together, but they are different questions. See what a capital-light business is.
What are the limits of ROIC?
- Negative capital. Apple's operating working capital plus equipment is about negative $0.1 billion on this basis, so its ROIC is not meaningful, and Visa and AutoZone's net working capital is negative too.
- Invisible assets. Research, brands and software are expensed, not counted as capital, so asset-light firms look better than the figure shows.
- One year. A cyclical company's ROIC swings with the cycle; look at several years.
- Banks and insurers. Capital is their raw material, so the measure does not apply.

ROIC FAQ
What is a good ROIC?
One that stays above the company's cost of capital for years. Among the eight examples in this post, ROIC runs from 10% to 59%, with Exxon Mobil and AT&T near 10% and Altria, AutoZone and Coca-Cola above 40%.
What is the difference between ROIC and ROE?
ROE divides net income by shareholders' equity, so debt and buybacks can inflate it. ROIC divides operating profit after tax by all the capital the business uses, so financing choices matter less.
What is the difference between ROIC and ROA?
ROA divides net income by total assets, which include cash and every other asset. ROIC leaves out cash and non-interest liabilities such as payables, so it measures the capital that actually runs operations.
Can ROIC be negative or meaningless?
Yes. It is negative when operating profit is negative, and it is not meaningful when invested capital is zero or below, which happens to firms with large negative working capital. Apple's operating capital on this site's basis is about negative $0.1 billion.
Does this site publish ROIC?
Not as a ranking. The capital-light analysis uses a related measure, the profit added for each dollar of capital added over 10 and 15 years, rather than a one-year level.
