Quick answer: Gross profit is an amount of money. Gross profit margin expresses that amount as a percentage of sales. They are related, but the figure with the higher percentage does not always represent the greater amount of profit.
Enter cost and selling price in the BuzBolt Profit Margin Calculator to view the amount and percentage together.
Compare two illustrative businesses
| Example | Sales | Direct costs | Gross profit | Gross margin |
|---|---|---|---|---|
| Business A | $100 | $50 | $50 | 50% |
| Business B | $10,000 | $8,000 | $2,000 | 20% |
Business A has the higher percentage. Business B has the higher currency amount. This is why the two figures should be read together when comparing transactions or periods.
Work out the gross profit amount first
Subtract the relevant direct costs from revenue. If a service is billed at $250 and the direct cost included in the calculation is $175, the gross profit amount is $75. Divide $75 by $250 and multiply by 100 to obtain a 30% gross margin.
One percentage can hide differences in scale
A 10% gross margin on $100,000 of sales represents $10,000 gross profit. A 50% margin on $1,000 of sales represents only $500. Neither number on its own tells you net profit, cash flow or overall business performance; additional costs may still apply.
Choose the right measurement for your question
- How much gross profit did the sale produce? Use the currency amount.
- How much of the sale value was gross profit? Use gross margin.
- How much profit relative to cost? Use markup, a separate measure.
A simple check
If the gross profit is $75 on sales of $250, margin must be 30% because $75 is three-tenths of $250. If a displayed percentage is greater than 100% with positive sales and non-negative cost, recheck inputs and which denominator the formula uses.
