💹 Profit Margin Calculator

Selling a product and want to know how much you really earn on each sale? Enter the cost price and the selling price to see your profit, your profit margin percentage and your markup percentage — the three numbers every seller should know.

How to use the Profit Margin Calculator

  1. Enter the cost price (what the product costs you).
  2. Enter the selling price (what the customer pays).
  3. Press Calculate — profit, margin and markup appear below.
Example: If a product costs you Rs 800 and you sell it for Rs 1,000, your profit is Rs 200, your margin is 20% and your markup is 25%.

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 price. The same Rs 200 profit is a 20% margin but a 25% markup on an Rs 800 cost.

Can the margin be more than 100%?

No — margin can never exceed 100%, because profit is always part of the selling price. Markup, however, can go far beyond 100%.

What if the selling price is lower than the cost?

Then the result shows a loss — a negative profit and a negative margin — so you can see exactly how much you lose on each sale.
