Formulas

Core Formulas

1. From EBIT (Operating Income)

2. From Net Income

Where:

3. From EBITDA

Step 1 — Convert EBITDA → EBIT:

Then apply standard NOPAT formula:

4. From Revenue & Expenses (direct method)

Then:


NOPAT Margin

If revenue is provided:

Example

Inputs:

  • EBIT = $240,000
  • Tax Rate = 25%
  • Revenue = $1,000,000

Step 1 — Calculate NOPAT


Step 2 — NOPAT Margin

How to Use the NOPAT Calculator

Start from EBIT, net income, EBITDA, or detailed revenues and expenses, and get a clean NOPAT figure plus NOPAT margin in a few clicks:

  1. Choose your method

    • From EBIT (Operating Income) – use this if you already know EBIT from the income statement.
    • From Net Income – use this if you have Net Income and Interest Expense, and you want an approximate NOPAT by adding back interest after tax.
    • From EBITDA – use this if you know EBITDA and can break out Depreciation and Amortization.
    • From Revenue & Expenses – use this if you only have top-line Revenue, COGS, and Operating Expenses (plus D&A) and want the tool to estimate EBIT for you.
  2. Enter the tax rate

    • In Tax Rate (%), type the corporate income tax rate as a percentage (for example, enter 25 for 25%).
    • This rate is used to convert EBIT (or its estimate) into after-tax operating profit.
  3. Fill in the method-specific inputs

      • From EBIT tab:

    - Enter EBIT (Operating Income).

      • From Net Income tab:

    - Enter Net Income.

    - Enter Interest Expense (the calculator adds back interest after tax).

    - (Optional) Enter Taxes (for EBIT) if you want EBIT to be shown in the results.

      • From EBITDA tab:

    - Enter EBITDA.

    - Enter Depreciation and Amortization so the tool can compute EBIT = EBITDA − D − A.

      • From Revenue & Expenses tab:

    - Enter Revenue.

    - Enter Cost of Goods Sold (COGS).

    - Enter Operating Expenses (excl. D&A).

    - Enter Depreciation and Amortization.

    - The calculator first estimates EBIT = Revenue − COGS − Operating Expenses − Depreciation − Amortization, then applies the tax rate.

  4. (Optional) Enter Total Revenue for NOPAT margin

    • In Total Revenue (optional, for margin), type the total revenue you want to use as the base for margin (often the same as the period revenue).
    • If you leave this blank, you still get NOPAT, but NOPAT Margin (%) will not be meaningful.
  5. Click Calculate

      • Press the Calculate button at the bottom.
      • The Results panel will populate with:

    - EBIT (Operating Income) – the operating profit before tax (input or derived).

    - NOPAT – Net Operating Profit After Tax in currency.

    - NOPAT Margin – NOPAT divided by Total Revenue, shown as a percentage.

  6. Read and interpret the results

    • A higher NOPAT means the core operations are generating more after-tax profit, independent of financing structure.
    • A higher NOPAT Margin (%) means the business keeps more after-tax operating profit per dollar of revenue.
    • Use NOPAT as an input into metrics like ROIC, or to compare operating performance across companies with different capital structures.
