Estimates from the figures you enter. Not financial or tax advice.
Enter what you paid for the piece, what it sells for and what the buyer pays for shipping. Then add what the sale costs you: the shipping label, packaging or cleaning, and the fees. Selling platforms usually take a percentage of the sale, sometimes plus a fixed amount per order, and payment processing can add its own percentage and fixed fee. Rates differ between platforms and change, so the boxes start with neutral example values: replace them with the figures from your platform's current fee page, and save them as a set to reuse.
Profit = buyer pays − fees − shipping label − item cost − other costs
Margin = profit ÷ buyer pays
Return on cost = profit ÷ (item cost + other costs)
The break-even price is the item price at which the sale leaves exactly nothing; below it, you pay to sell. Set a profit goal to see the price that reaches it.

It divides profit by what you spent, so a $2 find that earns $20 shows 1,000%. That helps when deciding what to buy, but the profit in money tells you more about whether a sale was worth your time.
No. Sales tax collected by a platform and income tax on your profits depend on where you live and how much you sell. Check the rules with your tax authority.
