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. A product bought at 100 and sold at 150 has a 50% markup but a 33.3% margin. Confusing the two is one of the most common pricing mistakes.

How do I calculate profit percentage?

Subtract total cost from total revenue to get profit, then divide by whichever base you want — revenue for margin, cost for markup — and multiply by 100. This calculator shows both.

Can I include shipping and fees?

Yes. Put them in the 'other costs' field and they are added to your total cost before profit is worked out.

What if I made a loss?

Enter your figures as normal. If cost exceeds revenue the result panel turns red and shows the net loss along with the negative margin.
