Free ROIC Calculator
Calculate return on invested capital from operating income, tax rate, and invested capital. Compare ROIC to the cost of capital to see whether a business creates or destroys value.
NOPAT $750 ÷ invested capital $5,000
That is 6.0 points above the cost of capital. The business is creating economic value on the capital it deploys.
What ROIC tells you
Return on invested capital answers one question: for every dollar this business puts to work, how much after-tax operating profit does it earn? A business that earns 20% on its capital in a world where capital costs 9% is creating real economic value. A business that earns 8% in the same world is on a treadmill. It reports profits and may even grow, but it returns less than the capital it consumes. Over a decade that gap compounds, in one direction or the other.
How the calculation works
- Start with operating income (EBIT) and apply the effective tax rate to get NOPAT, the net operating profit after tax.
- Divide NOPAT by invested capital, which is equity plus net debt (gross debt minus excess cash), excluding non-operating assets.
- Compare the result to the cost of capital. The spread between them is where value is created or destroyed.
ROIC as evidence of a moat
In a competitive market, high returns on capital attract competition, and returns drift back toward the cost of capital over time. A business that holds a high ROIC for many years, through a full cycle, is telling you something structural is protecting it. ROIC sustained above 15% across a decade is one of the clearest quantitative signatures of a durable competitive advantage. The trend matters as much as the level: a rising ROIC suggests a widening moat, a falling one is an early warning that the advantage is eroding.
Assumptions and limits
Compare ROIC within an industry rather than across industries. Asset-light businesses such as software and payment networks naturally run higher returns than capital-heavy manufacturers. Goodwill treatment is a judgment call: include it to measure the return on all the capital management has deployed, or exclude it to see the return on the underlying operating assets. Whichever you choose, be consistent, and read several years together rather than a single one.

Frequently asked questions
- What is return on invested capital (ROIC)?
- ROIC measures how much after-tax operating profit a business generates for every dollar of capital invested in it. The formula is Net Operating Profit After Tax (NOPAT) divided by invested capital. It is the most complete single measure of business quality, because it captures both profitability and how much capital was needed to produce it.
- How do I calculate ROIC?
- Start with operating income (EBIT) and multiply by one minus the effective tax rate to get NOPAT. Then divide NOPAT by invested capital, which is equity plus net debt (gross debt minus excess cash), excluding non-operating assets. This calculator does both steps for you once you enter the figures.
- What is a good ROIC?
- What matters is ROIC relative to the cost of capital. A business earning 20 percent ROIC where capital costs 9 percent is creating substantial value. A business earning 8 percent in the same world is destroying value despite reporting profits. As a rough guide, ROIC sustained above 15 percent over a full cycle is a strong signal of a durable competitive advantage.
- Why does ROIC matter more than profit margin?
- Margin ignores the capital required to generate the profit. Two businesses with identical margins can have very different ROIC if one needs three times the capital to produce the same revenue. ROIC is also capital-structure neutral, so it measures the return on the business itself rather than the effect of leverage.
