Net Profit Margin Calculator

About this calculator

This calculator finds net profit margin — net income divided by total revenue, expressed as a percentage — showing how much of every dollar (or lira) in sales actually turns into profit after all expenses, taxes and interest are paid.

Business owners use it to track profitability over time, investors and analysts use it to compare companies regardless of size, and lenders check it when assessing how financially healthy a business is. Just enter net income and revenue for the period you want to measure.
