Operating profit as if the company had no debt.
Net operating profit after tax
Estimates for planning only, not financial advice.
NOPAT is the profit a company's operations would earn if it had zero debt: earnings before interest and tax, with tax applied as if interest did not exist. It strips out financing so you can judge the business on its own merits. Two identical operations, one debt-free and one heavily borrowed, have the same NOPAT and very different net income, which is exactly the point.
How to Use This Calculator
Enter EBIT, which is operating income before interest and tax. You can find it on the income statement or compute it as gross profit minus operating expenses. Enter the corporate tax rate; 21 percent is the US federal rate, though the effective rate a company actually pays often differs. Add depreciation and amortization if you want the rough operating cash figure too.
Start from EBIT, not net income. If you only have net income, add back interest and the tax shield: NOPAT equals net income plus interest times (1 minus tax rate).
Apply the tax rate to get NOPAT. This is the unlevered profit the whole enterprise earned for all its capital providers.
Use it as the numerator for RNOA or economic profit. Our net operating assets calculator provides the denominator.
The NOPAT Formula
The second form shows the logic: net income was reduced by the full interest expense, but interest carries a tax shield, since interest is deductible. Adding back only the after-tax interest removes the financing effect cleanly. What remains is what the operations earned for both lenders and owners combined.
Worked Example
A company reports EBIT of $400,000 and faces a 21 percent tax rate. NOPAT is $400,000 times 0.79, which is $316,000. If the same company carried debt with $50,000 of annual interest, its net income would be lower by $39,500 after the tax shield, but NOPAT stays $316,000 either way. Add back $60,000 of depreciation and you get $376,000 as a rough proxy for operating cash before working capital changes.
Reading Your Result
NOPAT is the starting point for serious valuation. Free cash flow builds on it by adding back non-cash charges and subtracting investment. Economic profit subtracts a capital charge from it. Return on net operating assets divides by it. If your NOPAT is growing but free cash flow is not, the business is reinvesting heavily, and the next question is whether those investments earn their keep.
My rule: always pair NOPAT with the capital that produced it. A $316,000 NOPAT is excellent on $1 million of operating assets and mediocre on $10 million. Profit without the capital base is half a story. For the cash-flow view that follows from here, our operating cash flow calculator continues the build.

Frequently Asked Questions
What is NOPAT?
NOPAT stands for net operating profit after tax. It is EBIT with tax applied as if the company had no debt. It measures what the core operations earned for all capital providers, lenders and owners together, without letting financing choices distort the picture.
How do you calculate NOPAT?
Multiply EBIT by one minus the tax rate: NOPAT = EBIT x (1 - tax rate). If you only have net income, use the equivalent form: net income plus interest expense times (1 - tax rate), which adds back the after-tax cost of debt.
What is the difference between NOPAT and net income?
Net income subtracts interest and reflects the actual tax paid, so it belongs to shareholders only. NOPAT ignores debt, so it belongs to the whole enterprise. The gap between them is the after-tax interest: the return that went to lenders instead of owners.
Why do valuation models use NOPAT instead of net income?
Because enterprise value prices the whole company, debt included, so the profit measure must also cover the whole company. Discounting net income, which is equity-only, against enterprise value would mismatch the numerator and denominator. NOPAT keeps both sides consistent. This is also why DCF uses unlevered free cash flow: the valuation must stay capital-structure neutral.
Should I use the statutory or effective tax rate?
For a clean theoretical NOPAT, the statutory rate (21 percent federal in the US) is standard. For what the company actually earned, the effective rate from its tax footnote is more honest, since credits and foreign rates change the real burden. State which one you used.
What is the difference between NOPAT and EBIT?
EBIT is before tax; NOPAT is after tax. EBIT shows operating earning power ignoring both financing and tax, while NOPAT answers what the operations keep after the government is paid. Most return and valuation ratios want the after-tax version. In practice, NOPAT = EBIT x (1 - tax rate), the single line you will compute most often.
How does NOPAT relate to free cash flow?
Free cash flow starts from NOPAT, adds back non-cash charges like depreciation, then subtracts capital expenditures and increases in working capital. NOPAT is the profit; free cash flow is the cash left after funding the growth that produced it. Memorize the bridge: NOPAT, plus D&A, minus capex, minus change in NOWC, equals free cash flow.
What is NOPAT margin?
NOPAT divided by revenue. It shows how much after-tax operating profit each sales dollar produces, ignoring financing. Rising NOPAT margin with flat revenue means improving efficiency; falling margin means costs or taxes are outpacing sales. Compare it to peers on the same tax basis, since different effective tax rates can flatter or punish the margin.
Can NOPAT be negative?
Yes, when EBIT is negative the business lost money on operations before financing even enters. A negative NOPAT means the core business destroys value, and no clever capital structure fixes that. Turnaround has to happen in operations first. Persistent negative NOPAT with positive operating cash flow usually means heavy non-cash charges masking real losses.
Is NOPAT a GAAP measure?
No. GAAP does not define NOPAT, EBIT, or EBITDA; they are non-GAAP measures analysts compute from GAAP statements. Companies sometimes publish their own versions with adjustments, so rebuild it from the statements yourself when comparability matters. EBITDA is even further from GAAP, which is why lenders define it precisely in every credit agreement.
