About the Markup Calculator

The Markup Calculator works out selling price from cost and markup percentage, and converts between markup and 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

  • Setting retail prices from wholesale cost.
  • Converting a supplier's markup into your real margin.
  • Building a price list.

The maths behind it

This tool uses price = cost × (1 + markup ÷ 100), and the equivalent margin = markup ÷ (100 + markup) × 100. Every intermediate value is shown on screen, so the result can be checked by hand.

Frequently asked questions

Are there any usage caps on the Markup Calculator?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the utility.
Is the Markup Calculator safe to use with private information?
No. The Markup Calculator runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
Can I check the maths myself?
It uses price = cost × (1 + markup ÷ 100), and the equivalent margin = markup ÷ (100 + markup) × 100. The full working is printed under the result, so you can follow every step rather than trusting a black box.
Who is the Markup Calculator for?
In practice it gets used for three things: setting retail prices from wholesale cost. Converting a supplier's markup into your real margin. Building a price list. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Can I rely on this for exact work?
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.
