Net Profit Margin Ratio

Net Profit Margin Ratio =

Net income


AKA: Bottom line ratio


The net profit margin shows how much of every $1 in sales is retained as profit after accounting for all the costs involved in generating those revenues.

Business owners, managers, and others use this ratio as an indication of the overall health of a company and its ability to generate profit and control costs.

Note: expanded calculation

Sales revenue minus all expenses divided by sales revenue, multiplied by 100% to express as a percentage.


M&M company reported a net profit margin of 35% during the last quarter, meaning that it keeps a profit of 0.35 cents for every $1 of sales generated.


It’s helpful to compare the net profit margin to the company’s history (past performance) and its peers.

A “good” net profit margin varies by industry. Still, a general rule of thumb is that a 20% or higher margin means the company is efficient at turning sales into actual profit, a 10% margin is average, and a 5% margin is low. And a negative net profit margin means the company was unprofitable.
