Same sale, every marketplace

Your numbers from above, run through each marketplace's standard fees. Highest profit first.

Poshmark's fee includes the shipping label and buyers pay Poshmark for shipping, so its row ignores your shipping numbers. StockX and Poshmark charge on the item price only. Fees are standard US rates checked in November 2026; categories, seller levels, store plans, promotions, ads and sales tax can change them, so check your marketplace's fee page before relying on a number.

Business Hub for Notion

Do this for every product, automatically

This calculator handles one sale at a time. The Business Hub for Notion does it for your whole shop: profit after fees for every item, next to your sales, expenses, inventory and invoices on one dashboard.

How the numbers are worked out

Buyer pays = item price + shipping the buyer pays
Fees = fee % × (item price, + shipping if charged on it) + fixed fee
You receive = buyer pays − fees
Profit = you receive − item cost − shipping label − packaging & other
Margin = profit ÷ buyer pays

Break-even item price is the lowest price where you make $0. The item price for your goal is the lowest price that reaches your profit or margin target, rounded up to the cent. For the reasoning, and how to do it by hand, read how to price a product after fees.

Questions

Does eBay charge fees on shipping?

Yes. eBay's final value fee is a percentage of the total sale amount, which includes the shipping the buyer pays (and sales tax, which this calculator leaves out). So on eBay, charging $5 for shipping or adding $5 to the price gives you the same profit.

Does Etsy charge fees on shipping?

Yes. The 6.5% transaction fee applies to the item price plus shipping (and gift wrapping), and payment processing applies to the order total.

Why does Poshmark ignore my shipping numbers?

Poshmark charges $2.95 on sales under $15 and 20% on sales of $15 or more, and that fee includes a prepaid shipping label. Buyers pay Poshmark for shipping, so you don't pay for the label and shipping doesn't change your profit.

What profit per sale should I aim for?

There's no single right number, but many sellers set a minimum dollar profit as well as a margin. A 40% margin on a $6 item is only $2.40 for the same photographing, listing, packing and shipping work as a $60 item. Decide what an hour of your time is worth and check that your profit per sale covers it.

How accurate are the fees?

They're standard US rates, checked in November 2026. Your real fees can differ by category, seller level, store subscription, promotions, ads and sales tax, and marketplaces change their fees from time to time. Every fee box is editable, so you can match your own account.

Do you save my numbers?

Not on our side. The calculator runs entirely in your browser and only remembers your last inputs on your own device, so they're there next time. Nothing you type is sent to us.
