Frequently Asked Questions
What is the difference between margin and markup?▾
Margin is profit as a percentage of revenue (selling price), while markup is profit as a percentage of cost. Because the base differs, markup is always larger than margin when there is profit.
What is a good profit margin?▾
It varies by industry. Grocery retail often runs on thin single-digit margins, while software and services can exceed 50%. Compare your margin to peers in your sector rather than a universal number.
