About Margin Calculator
Profit margin is the percentage of revenue that remains as profit after costs. It is calculated as (Revenue - Cost) / Revenue x 100. Unlike markup (which is based on cost), margin is based on selling price. For example, if you buy for $30 and sell for $50, your margin is 40% but your markup is 66.7%. Understanding both metrics is essential for pricing strategy.
