About the Profit Margin Calculator

The Profit Margin Calculator calculates gross margin, markup, profit and the selling price you need to hit a target margin. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Pricing a product to hit a required margin.
  • Checking whether a discount still leaves you profitable.
  • Explaining to a client why margin and markup are not the same number.

The maths behind it

This tool uses margin = (price − cost) ÷ price × 100, while markup = (price − cost) ÷ cost × 100. The two are often confused: a 50% markup is only a 33.3% margin. Every intermediate value is shown on screen, so the result can be checked by hand.

Frequently asked questions

Do I need an account to use the Profit Margin Calculator?
There is no cost and no cap. The Profit Margin Calculator is not a demo of a paid product, so nothing is held back or watermarked.
Can you see what I put into this tool?
No. The Profit Margin Calculator runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What formula does the Profit Margin Calculator use?
It uses margin = (price − cost) ÷ price × 100, while markup = (price − cost) ÷ cost × 100. The two are often confused: a 50% markup is only a 33.3% margin. The full working is printed under the result, so you can follow every step rather than trusting a black box.
Give me a worked example.
Enter cost 40 and price 100 and the Profit Margin Calculator returns a 60% margin and a 150% markup.
When would I actually need the Profit Margin Calculator?
Typical uses: pricing a product to hit a required margin. Checking whether a discount still leaves you profitable. Explaining to a client why margin and markup are not the same number. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is the number rounded?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
