What Is NOPAT?
NOPAT — Net Operating Profit After Tax — measures a company's potential cash earnings from core operations if it had no debt. It strips out the effects of financing and capital structure by taxing operating income (EBIT) directly, making it a cleaner profitability metric than net income. Analysts use NOPAT to compute free cash flow, economic value added (EVA), and return on invested capital (ROIC).
How to Use This Calculator
Enter your Operating Income, also called EBIT (Earnings Before Interest and Taxes), and your effective or marginal tax rate as a percentage. The calculator instantly returns NOPAT along with the tax amount applied to operating income.
The Formula Explained
$$\text{NOPAT} = \text{EBIT} \times \left(1 - \frac{\text{Tax Rate (\%)}}{100}\right)$$ For example, if a firm has EBIT of $100,000 and a tax rate of 21%, the tax decimal is \(0.21\). $$\text{NOPAT} = 100{,}000 \times (1 - 0.21) = 100{,}000 \times 0.79 = \$79{,}000$$ The tax on operating income is \(100{,}000 \times 0.21 = \$21{,}000\).
Worked Example
Suppose a business reports EBIT of $250,000 and faces a 25% tax rate. $$\text{NOPAT} = 250{,}000 \times (1 - 0.25) = 250{,}000 \times 0.75 = \$187{,}500$$ This $187,500 represents the after-tax profit the operations generated, independent of how the business is financed.
FAQ
How is NOPAT different from net income? Net income includes interest expense and the tax shield from debt. NOPAT ignores financing entirely, taxing operating income as if the company were debt-free.
Which tax rate should I use? Most analysts use the company's effective tax rate or a marginal/statutory rate, depending on whether they want historical or normalized figures.
Can NOPAT be negative? Yes — if operating income (EBIT) is negative, NOPAT will also be negative, signaling operating losses.
