Find out whether a company actually creates value. Enter operating income (EBIT), the tax rate and invested capital to get return on invested capital — the number to compare against the cost of capital.
Answer first: return on invested capital measures the after-tax operating profit a company earns for every dollar of capital put to work in the business. This ROIC calculator converts operating income (EBIT) into NOPAT by removing taxes, divides it by invested capital, and — if you supply a WACC — tells you whether the company is creating or destroying value.
ROIC = NOPAT ÷ Invested capital, where NOPAT = EBIT × (1 − tax rate)
Example: $120M of EBIT taxed at 21% gives NOPAT of $120M × 0.79 = $94.8M. On $800M of invested capital that is a ROIC of 94.8 ÷ 800 = 11.85%. Against a 7% cost of capital, the company earns a healthy 4.85-point spread — genuine value creation.
ROIC is the metric many great investors watch above all others, because it captures the essence of a good business: taking capital and turning it into more capital at a high rate. Unlike return on equity, it counts both debt and equity capital, so leverage cannot fake it. And unlike raw growth, it tells you whether that growth is worth having — a company can grow revenue for years and still destroy value if each new dollar invested earns less than it costs.
ROIC only means something next to the cost of that capital. If a company earns 12% on capital that costs 7%, every dollar reinvested makes shareholders richer — that 5-point spread, compounded over years, is what builds enormous wealth. If ROIC sits below WACC, the opposite happens: growth actively burns money, and the business would create more value by returning cash to shareholders than by expanding. This spread, not the headline ROIC, is the real signal.
Invested capital is the total money financing the operating business: broadly, total debt plus shareholders' equity, minus any excess cash that is not needed to run day-to-day operations. Some analysts build it from the asset side instead — net working capital plus net fixed assets. Definitions vary, so when you compare two companies make sure you calculate invested capital the same way for both. This calculator takes your invested-capital figure directly so you can apply whichever convention you trust.
ROIC deliberately uses NOPAT — net operating profit after tax — rather than bottom-line net income. NOPAT strips out interest expense so the return reflects the operating business alone, independent of the financing mix. That makes ROIC comparable across companies with very different debt loads, which is exactly why it pairs so well with WACC: both are financing-neutral, so putting them side by side is a fair fight. A durable moat usually shows up as a high ROIC that stays high year after year while competitors' returns erode toward the cost of capital.
Reality check: ROIC depends on how you define invested capital and on one year's operating profit, which can be lumpy. This is an educational tool, not investment advice. For financial-statement basics, see the U.S. SEC at investor.gov.
Compare the return with the WACC calculator, cross-check profitability with the ROA and ROE calculators, and value the cash flows with the DCF calculator.

Broadly, a ROIC that consistently exceeds the company's WACC creates value. Many high-quality businesses earn 12%–20% or more, while a ROIC below the cost of capital signals value destruction. The spread over WACC matters more than the absolute level.
ROE measures return on shareholders' equity only and can be inflated by debt. ROIC measures return on all invested capital — debt plus equity — using after-tax operating profit, so leverage cannot distort it.
NOPAT is net operating profit after tax: EBIT multiplied by (1 minus the tax rate). It reflects the operating business's profit before financing costs, making it comparable across companies with different debt levels.
A common approach is total debt plus shareholders' equity minus excess cash. Some analysts build it from net working capital plus net fixed assets. Use one consistent definition when comparing companies.
