ROIC vs. ROE: Which Ratio Should Investors Use?

For most nonfinancial companies, ROIC is the better starting point for judging how well the business uses capital. ROE measures the accounting profit earned on common shareholders’ book equity. Banks are the main exception: because deposits and borrowing are part of their operating model, ROE is generally more informative.

The difference becomes useful when a company reports an unusually high return on equity. Borrowing more money or buying back stock can push ROE higher without improving operations. A stronger percentage may reflect a smaller equity base rather than better products, margins, or operating efficiency, as the DuPont breakdown of ROE helps explain.

What ROIC and ROE Actually Measure

A business needs capital to operate. Shareholders supply some of it, and lenders may provide the rest. That money supports the assets and investment needed to generate profits.

ROIC measures after-tax operating profit relative to invested capital. ROE narrows the calculation to the profit available to common shareholders relative to their book equity. Different earnings belong in the two formulas because the profits are being compared with different pools of capital.

These differences reflect the different capital claims being measured. CFA Institute’s capital-allocation framework treats ROIC as a company-wide return measure, while ROE focuses specifically on shareholders’ accounting equity.

For ROIC, the earnings figure is usually called NOPAT, or net operating profit after tax:

NOPAT ≈ Operating profit × (1 − operating tax rate)

A common starting point for invested capital is interest-bearing debt plus shareholders’ equity, minus excess cash. More complicated businesses require adjustments for non-operating investments, leases, and other ownership interests.

ROE’s denominator is book equity, not market capitalization. It is an accounting balance, not the price investors currently pay for the shares. A company earning 20% ROE therefore does not promise someone buying its stock a 20% annual return.

Both calculations normally use average capital balances. Annual profits are earned throughout the year, so using the average of beginning and ending capital generally provides a more useful comparison than dividing by the final balance alone.

Why Debt Can Raise ROE Without Improving the Business

Consider the same hypothetical business financed in two different ways. Its operations stay the same; only the mix of debt and equity changes.

Here is how the financing affects the numbers:

All dollar figures are in millions.

The business earns the same operating profit and uses the same total capital, so its ROIC is unchanged.

ROE rises because net income is divided by a much smaller equity base, even though net income fell. Shareholders now supply only half the capital, with lenders supplying the rest. Nothing about the underlying operations has improved.

Borrowing raises ROE here because the business earns more on its capital than the after-tax cost of the debt. But interest still has to be paid when operating profits weaken. The higher equity return comes with greater financial risk.

This simplified example assumes stable capital balances throughout the year and no non-operating income.

Apple: Why ROE Can Exceed 170%

Buybacks can also make the equity denominator unusually small. Repurchasing shares reduces shareholders’ equity, and years of repurchases can leave a large earnings stream supported by relatively little book equity.

Using Apple’s fiscal 2025 Form 10-K, the following illustrative calculations produce very different returns:

Calculations use beginning/end averages. NOPAT applies Apple’s reported effective tax rate to operating income. Invested capital is equity plus borrowings minus cash and cash equivalents; it retains marketable securities and makes no R&D or lease adjustments. These are illustrative calculations, not Apple-reported ratios.

Apple’s cash-flow statement shows $90.711 billion spent on share repurchases during that fiscal year. Book equity actually increased over the year, but the repurchases left it substantially below what it would have been had those funds remained in the company.

Both return calculations indicate high profitability relative to their respective accounting capital bases. Reading the 171.4% figure as evidence that Apple’s operating business is twice as productive as its ROIC suggests would confuse those capital bases. Neither percentage forecasts the return someone will earn buying Apple shares.

The value created by the buybacks is a separate question. It depends on the price paid relative to the value of the shares, not whether ROE increased afterward.

What Counts as a Good ROIC or ROE?

A return does not become attractive simply because it exceeds 15% or 20%. The business needs to earn more than the return required to justify its capital and risk.

ROIC should be compared with WACC, the weighted required return of lenders and shareholders. ROE belongs with the cost of equity, the return shareholders require for taking the equity risk. Matching WACC or the cost of equity to the analysis is also central to choosing an appropriate discount rate.

In a simplified example, a company earning 12% ROIC on $100 million of capital produces $12 million of after-tax operating profit. At an 8% cost of capital, it exceeds its annual capital charge by $4 million. Raise the cost of capital to 14%, and those same operating results fall short by $2 million.

Industry comparisons provide context, too. Damodaran’s January 2026 U.S. industry data showed return on capital of approximately 2.6% for Auto & Truck, 8.1% for Air Transport, and 29.7% for Soft Beverages. These are industry aggregates, not median-company results or definitions of what investors should consider good.

The differences are explored further in what constitutes a good ROIC across sectors and industries. For an individual company, the useful comparison combines its risks, peers, capital requirements, and ability to sustain the return.

Why ROE Is Usually More Useful for Banks

A manufacturer borrows to finance its operations. For a bank, gathering deposits and other funding is part of producing its financial services. Removing the cost of that funding would remove an important operating expense, which makes an industrial-style ROIC less useful.

ROE is a more natural starting point. Banks also commonly report return on tangible common equity, or ROTCE, which excludes goodwill and certain intangible assets from the equity base under the stated methodology.

JPMorgan Chase reported 17% ROE and 20% ROTCE for full-year 2025 in its earnings release. Those are company-reported measures, unlike the illustrative Apple calculations above.

Credit losses, funding stability, and capital strength still need to be examined alongside the return. A bank can report higher ROE while taking more risk or operating with less equity support.

ROIC Still Depends on How You Calculate It

Separating operating performance from financing decisions makes ROIC useful, but doesn’t make every figure labeled “ROIC” directly comparable.

Home Depot’s fiscal 2025 filing reported 25.7% ROIC, calculated from $15.897 billion of NOPAT divided by $61.914 billion of average debt and equity.

Its denominator uses long-term debt, including current installments, plus equity. Cash is not subtracted as it was in the Apple example. Home Depot explicitly identifies the measure as non-GAAP.

Before comparing two reported returns, check what went into them. A few choices can materially change the interpretation.

Including goodwill helps evaluate whether management earned an adequate return on the price paid for acquisitions. Excluding it can help compare underlying operating assets, but also removes part of the acquisition price from the calculation. The appropriate treatment depends on whether the investor is examining operating efficiency or management’s capital-allocation record.

Write-offs create a related problem. Once a failed acquisition is written down, future ROIC can improve because the accounting capital base is smaller. A stronger ratio afterward does not undo the money lost on the purchase. These acquisition effects are among the limitations of interpreting ROIC without examining its capital base.

Research-heavy businesses have a different accounting issue. Much R&D spending is expensed rather than recorded as a long-lived asset. Current earnings absorb the cost, while invested capital may omit years of spending that helped create the company’s technology. Capitalizing R&D analytically changes both earnings and capital, so the adjustment does not necessarily move the return in one predictable direction.

Consistency matters with lease adjustments, too. Adding lease obligations to invested capital without the corresponding operating-profit adjustment can distort the ratio. Subtracting cash needed to run the business as though it were entirely surplus can also make ROIC look stronger than it should.

Look at the numerator as carefully as the capital base. An unusual tax benefit may not recur. And stock-based compensation remains compensation, even though it is non-cash. Removing that expense without accounting for its economic cost makes profitability look better than it is.

Focus on the accounting choices large enough to change the investment conclusion rather than adjusting every line item just because an alternative calculation is possible.

How to Use Both Ratios When Evaluating a Stock

For a nonfinancial company, start with several years of ROIC and compare it with similar businesses using the same calculation method. ROE then helps identify how financing and the equity balance affect reported profitability. A list of high-ROE stocks can provide research candidates, but each unusually high result still needs an explanation.

Check the denominators before relying on a ranking. Equity or invested capital close to zero can produce extreme ratios, while negative balances can make the comparison meaningless. Those companies need a different analysis rather than an automatic “best” or “worst” label.

Historical returns also leave open how much the business can earn on new investment. A mature company may have excellent ROIC but few opportunities to reinvest. Another could earn a lower percentage while putting far more capital to work above its cost, creating more absolute value.

Consider a simplified example. Producing an additional $5 million of annual after-tax operating profit requires $20 million of new investment at a 25% return, compared with $50 million at a 10% return, once that investment is fully productive. The same profit increase requires $30 million less capital in the first case.

That difference affects how much cash can remain available to shareholders. Growth assumptions therefore need to be connected to reinvestment requirements and returns on new capital, rather than treated as something a business gets for free.

Stock Unlock’s stock screener can help narrow companies by profitability, growth, and financial-health criteria. After evaluating the business, the DCF calculator provides a separate place to test valuation assumptions. An attractive operating return does not settle what the stock is worth.

For most nonfinancial stocks, put ROIC first and use ROE to investigate the equity side of the result. Banks require the reverse emphasis. The investment case then depends on whether the returns can last, how much new capital the business can put to work, and what investors are paying for those economics.
