Frequently asked questions

What is a healthy profit margin for retail?

It varies by industry, but a 50% margin (doubling your cost) is a common rule of thumb in many general retail sectors.

Why is margin different from markup?

Markup is how much you add ON TOP of cost. Margin is how much of your final sale IS profit. They are different views of the same numbers.

How do I calculate markup from margin?

Markup = [ Margin / (100 - Margin) ] * 100. For example, a 20% margin equals a 25% markup.

Does this include taxes?

No, this calculator focuses on the gross profit relationship between cost and revenue. You should account for sales tax separately.
