11 Profit Margin

The profit margin, which we will express as a percent, is the percent of your business’s earnings that you get to keep. You want your profit margin to be as high as possible! The formula for calculating your profit margin is:

Net Profit Margin equals net profit divided by total revenue times one hundred

Let’s say your net profit, or income, for the month is $4,657.09, but your total income was $68,043.12. You would set up the problem like this:

fraction numerator $ 4 comma 657.09 over denominator $ 68 comma 043.12 end fraction space cross times space 100 space equals space 6.84 space left parenthesis r o u n d e d space t o space n e a r e s t space h u n d r e d t h right parenthesis

Your profit margin is 6.84%, which means that you get to keep 6.84% of your business’s earnings for the month.
