Open Profit & Loss Calculator →📌 What is Profit & Loss Calculator?
Margin and markup are the two numbers most often confused in pricing. Margin measures profit against the selling price; markup measures it against the cost. An item bought at 100 and sold at 150 has a 50% markup but a 33.3% margin — quoting one as the other can quietly wreck your pricing. This calculator always shows both.

❓ Frequently asked questions
What is the difference between margin and markup?
Margin is profit as a percentage of the selling price. Markup is profit as a percentage of the cost. They are different figures for the same sale.
How do I calculate profit percentage?
Subtract total cost from total revenue, then divide by revenue for margin or by cost for markup, and multiply by 100.
Can I include shipping and platform fees?
Yes. Enter them in the additional costs field and they are added to your total cost before profit is worked out.
What happens if I made a loss?
The result panel turns red and shows the net loss, along with the negative margin.
