Use this calculator to check whether a product or service price leaves enough room for profit.
Inputs
This topic also has a deeper guide and a printable reference pack, so you can move from the live answer into the method, assumptions, and worked examples without leaving the topic cluster.
A practical guide to markup, margin, discounting, ROI, and break-even thinking that keeps the definitions separate so pricing decisions are not distorted by similar-looking percentages that mean very different things.
A timeless guide to adding and removing VAT with editable rates, written to stay useful as a formula reference rather than a fixed legal statement about any one tax regime.
A clearer pricing sheet for markup, margin, discounting, and price logic, built to stop common denominator mistakes before they distort commercial decisions.
A stronger workbook-style pack for ROI, break-even thinking, contribution per unit, and practical commercial comparisons where volume and return both matter.
These are the main values the calculator uses. Keep the units consistent and, where relevant, match the assumptions explained in the related guide.
Unit: GBP
Use the direct cost basis you want to compare against the selling price.
Unit: GBP
Enter the revenue or sale price that the customer pays.
Use this page when you are pricing products, reviewing quotes, or checking whether a selling price leaves enough room for profit.
The main result is profit margin as a percentage of selling price. Supporting figures show the gross profit amount and the markup on cost.
If something costs 40 and sells for 65, the calculator shows both the cash profit and the percentage margin, which helps you compare prices on a like-for-like basis.
This calculator uses only cost and selling price. It does not include overhead allocation, tax, shipping, refunds, or any costs you do not enter.
Margin is measured against selling price, while markup is measured against cost. They are related, but they are not the same percentage.
Use the Markup Calculator to work out markup from values you control yourself, without baked-in policy assumptions.
Use the Break-Even Units Calculator to work out break-even units from values you control yourself, without baked-in policy assumptions.
Add VAT to a net amount using an editable rate that you control rather than a hardcoded tax assumption.
Use the Discount Calculator to work out discount from values you control yourself, without baked-in policy assumptions.
