What Is Gross Profit Percentage?
Gross profit percentage — also called gross profit margin — measures how much of each dollar of revenue remains after subtracting the direct cost of producing your goods or services (the cost of goods sold, or COGS). It is one of the most important profitability ratios because it shows how efficiently a business turns sales into profit before operating expenses, taxes, and interest.
How to Use This Calculator
Enter your total Revenue (net sales for the period) and your Cost of Goods Sold (direct costs such as materials, manufacturing, and labour). The calculator returns your gross profit amount and the gross profit percentage instantly. Use consistent figures from the same period for an accurate margin.
The Formula Explained
The formula is straightforward:
$$\text{Gross Profit \%} = \frac{\text{Revenue} - \text{COGS}}{\text{Revenue}} \times 100$$
First subtract COGS from revenue to get gross profit. Then divide by revenue and multiply by 100 to express it as a percentage. A higher percentage means more of every sales dollar is retained as profit.
Worked Example
Suppose a shop has revenue of $10,000 and COGS of $6,000. Gross profit is \(\$10{,}000 - \$6{,}000 = \$4{,}000\). The gross profit percentage is $$(\$4{,}000 \div \$10{,}000) \times 100 = \mathbf{40\%}$$ This means 40 cents of every sales dollar is gross profit available to cover overheads and generate net profit.
FAQ
What is a good gross profit percentage? It varies widely by industry — retail may run 20–40%, while software can exceed 80%. Compare against competitors in your sector.
Is gross profit margin the same as net profit margin? No. Gross margin only deducts COGS, while net margin also subtracts operating expenses, interest, and taxes.
What if revenue is zero? The percentage is undefined when revenue is zero, so the calculator returns 0 to avoid dividing by zero.
