Illustrative defaults, not a real company. Invested capital is measured from the financing side (debt plus equity minus excess cash); the operating side should give the same figure. To screen thousands of companies on return on capital with their own filed numbers, use the screener.
The ROIC formula the calculator uses
ROIC = NOPAT ÷ invested capital
NOPAT = operating income (EBIT) × (1 − tax rate)
Invested capital = debt + shareholders' equity − excess cash
Return on invested capital measures the after-tax operating profit a business earns on every dollar lenders and shareholders have tied up in it. Interest is left out on purpose: the question is how well the operations use capital, whoever supplied it, so two identical businesses with different debt levels show the same ROIC. The calculator measures invested capital from the financing side of the balance sheet because those lines are the easiest to find. The operating side, meaning working capital plus net fixed assets plus goodwill and intangibles, should add up to the same figure; the what is ROIC article shows both routes on the same company.
Two more outputs put the ratio to work. The spread is ROIC minus the weighted average cost of capital (WACC), the return lenders and shareholders require. Economic profit is NOPAT − WACC × invested capital: the dollars earned above the cost of all the capital used. A business can report a healthy operating margin and still have a negative economic profit if it needs a great deal of capital to earn it.
Where to find each input in a 10-K
| Input | Where it is | What to watch |
|---|---|---|
| Operating income (EBIT) | Income statement, "operating income" or "income from operations" | Remove gains, impairments and restructuring charges that will not recur |
| Tax rate | Income tax note, the effective rate, or the statutory rate if the year was distorted | A one-off tax benefit makes a normal year look unusually profitable |
| Debt, including leases | Balance sheet: short-term and long-term debt plus operating lease liabilities | Treat leases the same way for every company you compare |
| Shareholders' equity | Balance sheet, total equity including minority interests | Large buybacks can shrink book equity without changing the business |
| Excess cash | Cash and marketable securities beyond what operations need | Many analysts keep 2% of revenue as operating cash and treat the rest as excess |
| Cost of capital | Your own estimate; 8% to 10% is a common range for a large, stable company | Riskier or smaller companies warrant a higher rate |
Capital is a balance-sheet snapshot while profit is earned over a year, so for a careful figure average the opening and closing invested capital, or use the opening balance, and apply the same convention to every company. VALYSTR's company pages pull these line items from SEC filings, and the screener can rank thousands of companies on a return-on-capital rule without any hand entry.
Worked example: the default inputs (illustrative)
The defaults describe PackCo, a fictional packaging maker. It earned $300 million of operating income last year and pays tax at 25%, so NOPAT = 300 × 0.75 = $225 million. Its balance sheet shows $600 million of debt including leases, $1,150 million of shareholders' equity and $200 million of cash that the business does not need, so invested capital = 600 + 1,150 − 200 = $1,550 million.
- ROIC = 225 ÷ 1,550 = 14.5%.
- Spread at a 9% cost of capital = 14.5% − 9% = +5.5 percentage points.
- Economic profit = 225 − 0.09 × 1,550 = $85.5 million a year.
Now change one input. Raise the cost of capital to 16% and the spread turns to −1.5 points: the same business, the same profit, but growth would now destroy value because every reinvested dollar earns less than it costs. Set excess cash to $2,000 million and the calculator refuses to answer, because invested capital has gone negative. That is not a bug in the arithmetic; it is a sign that the cash estimate is wrong, or that the business genuinely runs on its customers' money, in which case ROIC is the wrong lens and the trend in operating profit says more.
How to read the result
A single ROIC figure is a starting point, not a verdict. Four questions turn it into one:
- Is it above the cost of capital? A spread near zero means growth adds revenue but no value; a comfortably positive one, sustained for years, is the signature of a business with some durable advantage.
- Is it stable? Compute it for five or more years. A cyclical business posts a high ROIC at the peak and a poor one at the trough; average through the cycle before comparing it with a steadier company.
- What is the return on new capital? The average return on everything ever invested matters less than what the next dollar earns. Estimate it as the change in NOPAT divided by the change in invested capital over several years.
- Does the price already know? A high-ROIC company is often priced as one. The reverse DCF guide shows how to work out the growth a price assumes, and the DCF example shows how ROIC and reinvestment together set the growth rate a model can honestly use.
In a stock screen, ROIC separates good businesses from merely cheap ones. Pair a return-on-capital floor with a valuation rule such as free cash flow yield, so the screen rewards quality at a reasonable price rather than quality at any price.
Common mistakes the calculator cannot catch
- Mixing conventions. Including leases in debt for one company and not another, or counting goodwill for one and not the other, makes the comparison meaningless. Decide once and apply it everywhere.
- Using net income instead of NOPAT. Net income is after interest, so leverage distorts it. That is the difference between ROIC and ROE, and it is why a debt-funded buyback can lift ROE while ROIC does not move.
- Counting all cash as excess. Treating every dollar of cash as surplus shrinks invested capital and flatters ROIC. Keep the cash the operations need.
- One distorted year. A gain on a disposal in operating income, or a tax benefit, produces a ROIC the business cannot repeat. Normalise first.
- Applying it to banks and insurers. For them debt is raw material rather than financing, so return on equity is the sensible measure.

Frequently asked questions
What is the formula for ROIC?
ROIC = NOPAT ÷ invested capital. NOPAT is operating income multiplied by (1 − tax rate). Invested capital is debt (including leases) plus shareholders' equity minus excess cash, or equivalently operating working capital plus net fixed assets plus goodwill and intangibles. Both routes should give the same number.
What is a good ROIC?
One that sits comfortably and consistently above the company's cost of capital. Many investors use a floor of 10% to 12% for a screen, but the right bar depends on the industry, the cost of capital and the conventions used. Consistency over a full cycle matters more than any single year.
What is the difference between ROIC and ROE?
ROIC divides after-tax operating profit by all the capital in the business, debt and equity alike, so it ignores how the company is financed. ROE divides net income by shareholders' equity only, so borrowing to buy back shares can raise ROE without improving the business. ROIC is the better gauge of operating quality outside banks and insurers.
How do I calculate invested capital?
From the financing side, add debt including lease liabilities to shareholders' equity and subtract excess cash and other non-operating assets. From the operating side, add operating working capital, net property and equipment, and goodwill and intangibles. If the two disagree, something has been classified inconsistently, usually cash, leases or deferred taxes.
Why does the calculator refuse to compute when invested capital is negative?
Because ROIC is undefined when the denominator is zero or negative. That happens when excess cash is estimated too high, or when a business genuinely collects cash from customers before paying suppliers. In the second case the business may be excellent, but the ratio says little; look at the trend in operating profit and the return on incremental capital instead.
