About Profit margin calculator

Gross profit margin and markup are related but distinct concepts that are frequently confused. Gross margin is profit expressed as a percentage of revenue (profit ÷ revenue × 100); markup is profit expressed as a percentage of cost (profit ÷ cost × 100). For the same numbers, markup will always be a higher percentage than margin. The Profit Margin Calculator shows both simultaneously, alongside the raw profit figure, from any combination of revenue and cost inputs. Understanding the difference matters in pricing strategy: a 50% markup yields only a 33% margin.
