About the Net Profit Margin Calculator
Net profit margin is what survives from every unit of revenue after cost of sales, operating expenses, interest and tax have all been paid. The calculation is net profit / revenue x 100. Unlike gross margin it hides nothing: a business with a fat gross margin and a bloated head office ends up with a thin net margin, and this ratio is where that shows.
Set a target percentage and the page works out the profit that target would demand at your current revenue, together with the gap in currency terms. It also solves the other direction, showing the revenue that would hit the target if profit stayed exactly where it is. Those two lines frame the classic choice between selling more and spending less, and the currency gap is usually more motivating than the percentage.
Judge the answer against the industry, never against a universal benchmark. Grocery chains and distributors live on one to three percent, manufacturers often sit near five to ten, and licensing or software businesses can clear thirty. A margin that jumps in a single year deserves scrutiny for one off items such as an asset sale or a tax credit, since those inflate the bottom line without any operating improvement. To strip financing and tax effects out and judge the operations alone, use the NOPAT Calculator.

Common questions
- What is the difference from gross margin?
- Gross margin only deducts the direct cost of sales. Net margin deducts everything, including salaries, rent, interest and tax.
- Can the margin be negative?
- Yes. Enter a loss as a negative profit and the percentage comes back negative, showing the loss per unit of revenue.
- Should revenue be before or after tax?
- Use revenue net of sales tax or VAT, since that money is collected on behalf of the government and was never yours.
- Why did my margin fall while profit rose?
- Revenue grew faster than profit. That often happens when growth is bought with discounting or with extra headcount.
