A simple gross-margin tool: it works on cost and selling price only and ignores VAT, overheads and other costs. For your true net margin after every cost, that’s what our management accounts do.
Margin and markup are easy to mix up — and getting them wrong quietly eats your profit. This calculator does both: give it your cost and price to see your gross profit, profit margin and markup, or set the margin (or markup) you want and it tells you the price to charge.
Markup vs margin — they’re not the same
Both describe the same gross profit, but against a different base — so the same money gives two different percentages. Quote a markup as if it were a margin and you’ll undercharge:
| Markup | Equivalent margin |
|---|---|
| 20% | 16.7% |
| 25% | 20% |
| 50% | 33.3% |
| 100% | 50% |
| 150% | 60% |
Margin = profit ÷ selling price. Markup = profit ÷ cost. Markup is always the bigger number.
Gross margin isn’t your real profit
This tool shows gross margin — price minus the cost of the item. Your real, take-home profit is lower, because it also has to cover:
- Overheads. Rent, software, marketing, wages and the rest of running the business.
- Selling costs. Marketplace and payment fees, delivery, packaging and returns.
- Tax. Corporation Tax or income tax on the profit that’s left, and VAT on the sale if you’re registered.
Strip all of that out and you have your net margin — the number that actually matters. Our management accounts show it by product and month, so you price to keep more.
The terms, explained
New to this? Here’s what the words on this page actually mean.
- Cost price
- What the item costs you — to buy, make or deliver — before you add any profit.
- Selling price
- What the customer pays. Selling price minus cost price is your gross profit.
- Gross profit
- The cash left over on a sale after the cost of the item, before overheads, tax and other costs.
- Profit margin
- Gross profit as a percentage of the selling price. A £10 profit on a £40 sale is a 25% margin.
- Markup
- Gross profit as a percentage of the cost. That same £10 profit on a £30 cost is a 33% markup — same money, bigger number.
