Free Profit Margin Calculator

What Is a Free Profit Margin Calculator?

A profit margin calculator computes the percentage of revenue that remains after subtracting costs. Gross margin is calculated as ((Revenue - Cost) / Revenue) x 100. If you sell a product for $100 and it costs $60 to produce, your gross margin is 40%. This metric tells you how efficiently you convert sales into profit and is the single most important number for any product-based business.

3. Read your profit margin: The calculator instantly shows your gross profit margin as a percentage, plus the dollar amount of profit per unit.
4. Test different price points: Adjust the selling price to see how different price points affect your margin — useful for finding the right balance between volume and profitability.
