Work out gross profit, margin percentage, markup percentage, or the selling price you need to hit a target margin. Fast, free, and fully client side.
Gross profit is the difference between your selling price and your cost price. Profit margin shows how much of the final selling price you keep as gross profit. Markup shows how much you added on top of cost.
These are not the same. If something costs £80 and you sell it for £120, the profit is £40. That means the markup is 50% because £40 is half of £80. But the margin is 33.33% because £40 is one third of the £120 selling price.
If you know your costs and want to hit a margin goal, divide cost by 1 minus the target margin as a decimal. Example: a cost of £80 with a 20% target margin needs a selling price of £100.
If you work in markup instead, multiply your cost by 1 plus the markup rate. Example: £80 cost with 50% markup gives a selling price of £120.
This is handy for pricing freelance work, wholesale products, service packages, and quick quote checks before you send invoices or update a price list.
