NOPAT Calculator
Calculate net operating profit after tax for any stock. Enter a ticker for live data, or type EBIT and a tax rate — get NOPAT and NOPAT margin, the numbers that drive ROIC and EVA.
Enter a ticker to calculate NOPAT
Try AAPL, MSFT, or any US-listed company. The calculator pulls operating income (EBIT) and the effective tax rate from live filings, then computes NOPAT — net operating profit after tax — along with the NOPAT margin.

What NOPAT Measures
Operating profit, financing-neutral
NOPAT — net operating profit after tax — is what the core business earns after tax but before any effect of how it is financed. It takes operating income (EBIT) and applies the tax the business would pay if it carried no debt. The result is a clean measure of operating profitability that two companies with different capital structures can be compared on fairly.
That financing-neutrality is the whole point. Net income mixes operating performance with interest expense and the debt tax shield; NOPAT strips those out so you are looking at the operations alone.
The numerator behind ROIC
Return on invested capital is NOPAT ÷ invested capital. Every ROIC figure you have ever read starts with a NOPAT calculation. If you want to understand whether a company creates value, NOPAT is step one and the cost of capital is step two.
When NOPAT-based ROIC clears WACC, growth compounds shareholder value; when it doesn't, growth destroys it. The ROIC guide walks through the full chain.
The starting point for EVA
Economic Value Added = NOPAT − (invested capital × WACC). EVA asks whether a company earned more than the dollar cost of the capital it tied up. Because it begins with NOPAT, a reliable NOPAT number is a prerequisite for any economic-profit analysis.
Use the effective tax rate
The 21% US statutory rate rarely equals what a company actually pays. Credits, deferrals, and foreign income shift the effective rate — income tax expense ÷ pre-tax income — sometimes by ten points or more. This calculator uses the effective rate from filings in ticker mode, and lets you set it (or pick a sector preset) in manual mode.
NOPAT vs Net Income vs EBITDA
Operating profit, after tax, no financing
EBIT × (1 − tax rate). Capital-structure neutral. The right profit figure for ROIC, EVA, and unlevered comparisons across peers with different debt loads.
Bottom line, after interest
Reflects actual capital structure — interest expense and the debt tax shield are baked in. Good for EPS and equity returns; misleading when comparing operations across different leverage.
Operating profit, before tax and D&A
Adds back depreciation and amortization and ignores taxes entirely. A cash-flow proxy, but it flatters capital-intensive businesses. NOPAT keeps the tax and the real cost of the asset base.
Pair NOPAT with invested capital
NOPAT on its own is a size figure. Divide it by invested capital to get ROIC, or subtract a capital charge to get EVA — that is where the value-creation signal lives.
Frequently asked questions
What is NOPAT?
NOPAT (Net Operating Profit After Tax) is a company's operating profit after subtracting taxes, but before the effect of financing. It answers: how much after-tax profit does the core business generate, ignoring how it is funded? Because it strips out interest and the debt tax shield, NOPAT is capital-structure neutral — which is exactly why it is the numerator in ROIC and the starting point for EVA.
What is the NOPAT formula?
NOPAT = EBIT × (1 − Tax Rate). EBIT is earnings before interest and taxes (operating income). The tax rate is the company's effective tax rate — income tax expense divided by pre-tax income — not the 21% statutory rate. For example, EBIT of $100M at a 21% effective rate gives NOPAT of $100M × (1 − 0.21) = $79M.
How is NOPAT different from net income?
Net income is after interest expense and reflects the company's actual capital structure. NOPAT deliberately ignores interest and the tax shield on debt, so it measures the profitability of the operations alone. Two companies with identical operations but different debt loads will show different net income yet the same NOPAT — which makes NOPAT the fairer number for comparing operating performance and computing returns on capital.
What is a good NOPAT margin?
NOPAT margin (NOPAT ÷ revenue) varies widely by industry, but as a rough guide: above 20% signals exceptional pricing power or a light cost base; 10–20% is healthy; below 10% is thin for a capital-light business but can be normal in high-volume, low-margin industries. What matters most is the trend and the comparison to peers — a rising NOPAT margin usually precedes rising ROIC.
Why is NOPAT used in ROIC and EVA?
ROIC = NOPAT ÷ invested capital, and EVA = NOPAT − (invested capital × WACC). Both use NOPAT because it isolates the after-tax cash return of the operations from financing choices. When NOPAT-based ROIC exceeds the cost of capital (WACC), each dollar reinvested creates value; when it falls below, growth destroys value even as revenue rises.
Should I use the statutory or effective tax rate for NOPAT?
Use the effective tax rate — the actual income tax expense divided by pre-tax income — because it reflects credits, deferrals, and geographic mix that the 21% US statutory rate ignores. This calculator pulls the effective rate from filings in ticker mode, and lets you type it or pick a sector preset in manual mode.
