Frequently asked questions
What is gross profit margin?
Gross profit margin is the percentage of revenue that exceeds the cost of goods sold: (Revenue - Cost) / Revenue × 100.
What is the difference between margin and markup?
Margin is profit as a percentage of selling price. Markup is profit as a percentage of cost price. A 50% markup equals a 33% margin.
Is this calculator free?
Yes, completely free. No account or data uploaded.
Can I calculate reverse margin (cost from price + margin)?
Not currently — but you can enter a target price and adjust the cost until the margin matches your target.
What is a good profit margin?
It depends on the industry. Retail averages 2–5%, software 70–80%, services 10–30%.
Does this include fixed costs?
No — this calculates gross margin only. To calculate net margin, include overheads in your cost price.
