Know your real profit on every sale

The number that matters is not your sale price — it's what lands in your pocket after the platform, the payment processor, shipping, and ads all take their cut. This calculator adds up every deduction and shows your true net profit, your margin as a percentage of the sale price, and the break-even price below which you lose money. Everything runs in your browser: no sign-up, and none of your numbers leave your device.

Because every marketplace charges differently, the fee fields are fully editable. The defaults (6.5% + $0.20 platform, 3% + $0.25 processing) are approximate figures you can edit; always check your platform's current fee schedule — results are estimates only, not financial advice.

How to use it

Enter your sale price — the total the buyer pays you for the item.
Add your product cost (what you pay to make or buy it) and the shipping cost you cover.
Set the platform fee percentage and fixed fee to match your marketplace, and do the same for payment processing.
If you run ads, enter your average ad cost per sale (total ad spend ÷ sales it generated).
Read the results instantly: net profit, margin %, total fees, and break-even price update as you type.

FAQ

What is a good profit margin per sale?: Many handmade and print-on-demand sellers aim for 30–50% net margin. Below 20%, one fee change or a single return can wipe out your profit, so treat thin margins as a warning sign.
What does the break-even price mean?: It's the sale price at which your profit is exactly $0 given your current costs and fees. Price above it and you earn money; price below it and every sale costs you money.
Should shipping charged to the buyer be included?: Yes — if the buyer pays for shipping, include that amount in the sale price, since most platforms charge their percentage fee on the shipping total too. Then enter what the postage actually costs you as the shipping cost.
How do I estimate ad cost per sale?: Divide your total ad spend over a period by the number of sales those ads produced. If you spent $50 on ads that drove 10 sales, enter $5.
