» Profit Margin Calculator


Profit Margin Calculator: calculate profit margin from net income and net sales, or solve for a missing value.

Use this profit margin calculator to calculate net profit margin, net income, or net sales. Profit margin is one of the simplest ways to see how much of each sales dollar remains as profit after all expenses.

Because profit margin includes operating costs, financing costs, and taxes, it is broader than gross margin or operating margin. It works best when compared with similar businesses and prior periods instead of as a standalone pass or fail metric.

Profit Margin


$$\text{Profit Margin} = \left( \frac{\text{Net Income}}{\text{Net Sales}} \right)$$

$$\mathrm{PM} = \frac{\mathrm{NI}}{\mathrm{NS}}$$

Profit Margin Calculator FAQ

What is profit margin?
Profit margin shows net income as a percentage of net sales. It tells you how much of revenue is left as final profit after all expenses.

What is the profit margin formula?
Profit margin = Net income / Net sales. This calculator can also solve for net income or net sales when the ratio and one input are known.

Why can profit margin be low even when gross margin is strong?
A company can have a healthy gross margin but still show a weak profit margin if operating expenses, interest costs, or taxes are high. That is why margin analysis is usually done in layers.

What is a good profit margin?
A good profit margin depends heavily on the industry, capital intensity, and business model. Compare the result with direct competitors and the company’s own historical range.

How should I interpret profit margin?
Higher profit margin generally means a larger share of revenue is turning into bottom-line profit, but the ratio can be affected by taxes, financing costs, and one-off items. It is best used together with gross and operating margin.
