Input Data
Results
At a glance:NOPAT is operating profit after tax, ignoring interest and financing. NOPAT = operating income × (1 − effective tax rate); tax on operating profit = operating income × effective tax rate. It reflects the business's earning power from operations.
Formula
NOPAT = operating income × (1 − effective tax rate).
Tax on operating profit = operating income × effective tax rate.
How to Use
- Enter the operating income (EBIT).
- Enter the effective tax rate.
- Read the NOPAT and the tax amount.
FAQ
What is the difference between NOPAT and net income?
Net income deducts interest expense and after-tax non-operating items, so it is affected by capital structure; NOPAT removes interest to show the profit of operations themselves. Roughly, NOPAT = (EBIT or operating profit) × (1 − tax rate), without the tax shield from interest.
Why is the tax rate not the actual rate paid?
NOPAT assumes the tax on operating profit without interest, so a theoretical tax rate is used — such as the statutory rate, or the effective rate excluding the interest tax shield. Use a consistent rate to make the figure comparable across companies; do not confuse it with the company's reported actual tax rate.
What is NOPAT used for?
NOPAT feeds return on net operating assets (RNOA = NOPAT ÷ NOA) and free cash flow (FCF = NOPAT − investment in net operating assets), and is a core input to enterprise-value and residual-income valuation. It strips out financing so the business's true earning power can be compared.
How do I derive NOPAT from EBIT and the tax rate?
The direct formula is NOPAT = EBIT × (1 − tax rate). EBIT (earnings before interest and tax) is operating profit before interest is deducted; multiplying by (1 − tax rate) gives the after-tax operating profit as if there were no debt. If you start from net income, add back after-tax interest: NOPAT = net income + interest × (1 − tax rate). In practice, if a company has no large non-operating items, using EBIT is the cleanest approach.
How does NOPAT differ from EBIT and EBIAT, and why use it for valuation?
EBIT is profit before interest and tax (the pre-tax operating profit), NOPAT is the after-tax version (EBIT × (1 − tax rate)), and EBIAT is essentially a synonym for NOPAT (earnings before interest after tax). The reason valuation uses NOPAT is that it isolates the earning power of core operations from the effects of financing and tax shields. Enterprise-value and residual-income models care about the cash the business itself generates, net of tax but independent of how it is funded (debt or equity). Because NOPAT strips out the interest tax shield, it pairs cleanly with net operating assets (NOA) to give RNOA and with capital investment to give free cash flow (FCF), avoiding the distortion that leverage imposes on net income. So use NOPAT to value the 'business' and net income to see the bottom line attributable to shareholders.
