NOPAT Calculator — Net Operating Profit After Tax
Compute Net Operating Profit After Tax (NOPAT) — the after-tax operating earnings a business generates regardless of its financing structure. Enter EBIT and the effective corporate tax rate; add invested capital to derive Return on Invested Capital (ROIC).

How does this calculator work?
NOPAT = EBIT × (1 − tax rate) — the after-tax operating earnings independent of financing. ROIC = NOPAT / Invested Capital; when ROIC exceeds the cost of capital the business creates value. Use the effective tax rate (actual taxes / pre-tax income) for best accuracy.
Formula
How this is calculated
NOPAT strips out the effect of capital structure — interest is excluded from EBIT, so NOPAT represents how profitable the core business operations are on an after-tax basis, whether the company is funded by debt or equity. It is the numerator in ROIC and a key input in Economic Value Added (EVA) and discounted cash flow (DCF) valuation: a business creates value only when its ROIC exceeds its weighted average cost of capital (WACC).
The formula is simple: NOPAT = EBIT × (1 − t), where t is the effective blended corporate tax rate. Analysts sometimes compute it bottom-up from net income: NOPAT ≈ Net Income + After-tax interest expense = Net Income + Interest × (1 − t), which should give the same result when the full income statement is available.
Return on invested capital (ROIC) = NOPAT / Invested Capital, where invested capital is typically net debt plus total equity minus non-operating assets. ROIC above the WACC (commonly 8–12 % for large companies) signals value creation; below it signals destruction. The tax rate used here is the effective rate on operating income — it may differ from the statutory rate if the company has deferred taxes, tax credits, or losses carried forward.
Frequently asked questions
Net income deducts interest expense (a financing cost) and may include non-operating items. NOPAT removes both: it starts from EBIT (before interest) and taxes it at the operating rate, giving the profit attributable purely to operations — independent of how the business is financed.
Use the effective blended corporate tax rate — total income taxes paid divided by pre-tax income from the income statement. The statutory rate (e.g. 21 % in the US, 25 % in the EU on average) is a common approximation, but the effective rate reflects real tax credits, incentives and deferred items.
ROIC above the company's WACC (usually 7–12 % for large developed-market businesses) indicates value creation. High-quality businesses commonly achieve 15–25 % ROIC. Compare within the same industry — capital-light businesses (software) naturally post higher ROIC than capital-heavy ones (utilities).
