Net Profit Margin Calculator
Calculate Net Income and Net Profit Margin from revenue, COGS, operating expenses, interest and income tax expense to measure bottom-line profitability.
Estimate Net Income and Net Profit Margin using the financial amounts you enter. All figures should relate to the same accounting period. Enter any applicable income tax expense directly from your records; the calculator does not estimate taxes. Calculations run locally in your browser; inputs are not saved.
Enter Revenue, COGS, Operating Expenses, Interest Expense and Income Tax Expense for the same accounting period.
Compare bottom-line Net Income with Gross, Operating and EBITDA margins, or review cash movement separately: the EBITDA Margin Calculator, Operating Margin Calculator, Gross Margin Calculator, Cash Flow Calculator and Profit Calculator.
Net Profit Margin Example
Revenue: $1,000,000. COGS: $600,000. Gross Profit: $400,000. Operating Expenses: $250,000. Operating Income: $150,000. Interest Expense: $50,000. Other Income / Expense: $0. Pre-Tax Income: $100,000. Income Tax Expense: $25,000. Net Income: $75,000. Net Profit Margin = $75,000 ÷ $1,000,000 × 100 = 7.5%. The business retains approximately $0.075 of Net Income per $1.00 of Revenue after the entered expenses. The dollar sign is illustrative; no currency is selected or converted.
About this calculator
What Is Net Profit Margin?
Net Profit Margin expresses Net Income as a percentage of Revenue after the entered COGS, Operating Expenses, Interest Expense, Income Tax Expense and any optional Other Income / Expense. Net Income is an accounting earnings measure, not cash flow.
Net Profit Margin Formula
Net Profit Margin = Net Income ÷ Revenue × 100. The percentage is unavailable when Revenue is zero.
Net Income Formula
Gross Profit = Revenue − COGS. Operating Income = Gross Profit − Operating Expenses. Pre-Tax Income = Operating Income − Interest Expense + Other Income / Expense. Net Income = Pre-Tax Income − Income Tax Expense. The optional Other Income / Expense defaults to zero.
What Does Net Profit Margin Measure?
It describes the share of the entered period’s Revenue remaining as Net Income after the listed income and expense items. Accounting classifications and applicable non-operating items can differ between businesses.
What Does a High Net Profit Margin Mean?
A higher positive Net Profit Margin generally means more Net Income remains per dollar of Revenue after the entered expenses. Pricing, Gross Margin, operating efficiency, financing costs, tax burden, scale and business mix may contribute. Higher does not automatically mean healthier.
What Does a Low Net Profit Margin Mean?
A lower positive margin may reflect lower Gross Margin, operating costs, interest or tax expense, growth investment or a different business model. It is not automatically weak, and this Tool does not diagnose the cause.
Can Net Profit Margin Be Negative?
Yes. A negative margin means the entered income and expense items result in a Net Loss for that period. It does not identify the cause or establish insolvency.
Other Income / Expense
This optional signed input is for net other income or expense for the same period. Positive values add other income; negative values subtract other expense. Keep Interest Expense separate, without netting interest income into that expense field.
Entering Income Tax Expense
Enter Income Tax Expense directly from appropriate financial records; this Tool does not infer a tax rate, jurisdiction or tax amount. Tax expense may appear alongside negative Pre-Tax Income due to tax accounting differences. The Tool does not calculate deferred taxes.
Net Profit Margin vs. Gross Margin
Gross Margin reflects Revenue after COGS. Net Profit Margin uses final Net Income after operating costs, financing costs, taxes and applicable other items. Compare gross results with the live Gross Margin Calculator.
Net Profit Margin vs. Operating Margin
Operating Margin measures Operating Income before interest and income taxes. Net Profit Margin includes the entered Interest Expense, Income Tax Expense and optional other items. These ratios answer different questions; Operating Income and EBIT may not be interchangeable for every financial statement.
Net Profit Margin vs. EBITDA Margin
EBITDA Margin uses EBITDA, before interest, taxes, depreciation and amortization. Net Profit Margin uses Net Income after the applicable entered expenses. Neither measure is universally superior; see the live EBITDA Margin Calculator for that distinct operating measure.
Net Income vs. Cash Flow
Net Income is an accounting earnings measure, not the same as cash flow. Depreciation, amortization, working-capital changes, capital expenditures, debt repayments, non-cash items and timing can make cash generated differ. Compare it with the live Cash Flow Calculator as a separate measure.
Net Profit Margin and Financial Health
Net Profit Margin should not be used alone to assess financial health. Relevant analysis may also consider Gross Margin, Operating Margin, EBITDA Margin, returns on assets and equity, cash flow, leverage and liquidity. Results vary significantly by industry, capital structure, tax environment, business model, maturity, pricing, scale and cost structure. There is no universal benchmark.
Frequently asked questions
What is Net Profit Margin?
Net Profit Margin is Net Income as a percentage of Revenue after the applicable income and expense items entered for the period.
How do you calculate Net Profit Margin?
Divide Net Income by Revenue and multiply by 100. When Revenue is zero, the percentage is unavailable.
What is Net Income?
In this calculator, Net Income is Pre-Tax Income minus the user-entered Income Tax Expense. Pre-Tax Income starts with Operating Income, minus interest expense, plus any signed optional other income or expense.
Is Net Income the same as profit?
Net Income is often called net profit or the bottom line in an income-statement context. Use the same accounting period and classifications when comparing amounts.
What is a good Net Profit Margin?
There is no universal threshold. Margins vary by industry, capital structure, tax environment, business model, maturity, pricing, scale and cost structure.
Is a higher Net Profit Margin always better?
Not automatically. Consider investment, accounting classifications and business context; this measure alone does not assess financial health.
Can Net Profit Margin be negative?
Yes. It indicates a Net Loss under the entered values for that period, but does not diagnose the cause or establish insolvency.
How is Net Profit Margin different from Gross Margin?
Gross Margin considers Revenue and COGS. Net Profit Margin uses final Net Income after other entered operating and applicable expenses.
How is Net Profit Margin different from Operating Margin?
Operating Margin uses Operating Income before interest and taxes. Net Profit Margin includes the entered Interest Expense, Income Tax Expense and other items.
How is Net Profit Margin different from EBITDA Margin?
Net Profit Margin uses Net Income after entered expenses. EBITDA Margin excludes interest, taxes, depreciation and amortization; the measures are not interchangeable.
Is Net Income the same as cash flow?
No. Non-cash items, working capital, capital spending, debt repayments and timing can make cash generated different from accounting Net Income.
Should I estimate taxes here?
No tax estimate is made. Enter the applicable Income Tax Expense directly from appropriate financial records.
Results depend on user-entered information; all values should cover the same accounting period. Accounting classifications, interest and tax treatment vary. Enter income tax expense from appropriate financial records; this Tool does not determine tax or accounting treatment. Net Income is not cash flow, and margin performance varies materially by industry and business model. The ratio should not be used alone to assess financial health.
