How to use the selling price calculator
- Type the purchase price in “What the item cost you”.
- Put your label or stamp cost in “Your own postage or label cost”.
- Add boxes, tape and other materials in “Packaging and other costs”.
- Enter what you charge the buyer for shipping in “Shipping you charge the buyer”. Leave 0 if shipping is free to the buyer.
- Under “I want to reach”, pick “A profit amount”, “A profit margin (%)” or “A return on cost (ROI %)”.
- Type the figure in “Target (amount or %)”: dollars for a profit amount, a percentage for the other two.
- Read the table. Its columns are Platform, Lowest listing price, Fees, “You keep (after platform fees)” and Profit.
The table is sorted from the cheapest answer to the dearest, and the cheapest row carries a tick. Rows change as you type, and the address in your browser updates with your inputs, so you can bookmark or send the exact figures. This page has no CSV download or ledger button; it is for working out a price, not for storing one. Compare the Fees column across rows to see where the money goes, since every row is built to leave the same profit.
How much should I sell it for?
The calculator gives you a floor, not a market price. It shows the smallest listing price at which your goal survives each platform’s fees. What buyers will actually pay comes from sold listings on the platform, so check those first. If the sold prices sit below the floor, change your target or stop buying that kind of item.
How do I calculate a sales price?
Add your costs, add the profit you want, then find the listing price at which the platform keeps its fees and leaves exactly that sum. The tool does this search for you. Take a $10.00 item, $5.00 postage, $0.50 packaging, a $10.00 profit goal and free shipping to the buyer.
You must keep $10.00 + $5.00 + $0.50 + $10.00 = $25.50 after fees. These are the lowest listing prices that leave $25.50, from the engine:
| Platform | Lowest listing price | Fees | You keep |
|---|---|---|---|
| Depop | $26.84 | $1.34 | $25.50 |
| TikTok Shop | $27.13 | $1.63 | $25.50 |
| Mercari | $28.33 | $2.83 | $25.50 |
| Facebook Marketplace | $28.33 | $2.83 | $25.50 |
| Etsy | $28.67 | $3.17 | $25.50 |
| Whatnot | $28.96 | $3.46 | $25.50 |
| Grailed | $28.99 | $3.49 | $25.50 |
| eBay (US) | $29.98 | $4.48 | $25.50 |
| Poshmark | $31.87 | $6.37 | $25.50 |
Profit is $10.00 in every row. The gap between the cheapest and dearest row is $5.03.
What is the formula for selling price?
For a margin goal with one percentage fee and one fixed fee, the price is (total costs + fixed fee) ÷ (1 − fee rate − target margin). With $15.50 of costs on Mercari (10% fee, no fixed fee) and a 30% margin, that is $15.50 ÷ 0.60 = $25.83, the same figure the tool returns.
The tool does not rely on the formula, because fees are rarely that simple. Poshmark charges a flat $2.95 under $15 and 20% from $15, so the curve steps. The tool therefore searches by the cent and walks down to the lowest price that still works.
What if a platform shows “Not reachable with these fees”?
That row means no listing price up to about $20,000,000 leaves your goal after that platform’s fees. It happens mostly with high margin goals, because a platform that takes 10% or 20% of the price can never leave you more than 90% or 80% of it as margin. With the costs above and a 90% margin goal, Depop ($238.00), TikTok Shop ($387.40), Etsy ($3,189.15) and eBay ($11,237.20) still have an answer, while Poshmark, Mercari, Facebook Marketplace, Whatnot and Grailed read “Not reachable with these fees”. These rows sit at the bottom of the table. Lower the target or compare the other rows.
Should I price on margin or markup?
Margin divides profit by the selling price, so it matches what you keep from each sale. Markup divides profit by cost and always looks bigger. A 50% markup is a 33.3% margin, and a 30% markup is a 23.1% margin. Choose “A profit margin (%)” when you think in margins.
Which fees are included?
Each platform runs with its default options, and the page links its sources with the date they were checked. Whatnot uses the standard tier and the “Everything else” category. Not included: Depop’s buyer-side marketplace fee, which Depop does not publish exactly, and Etsy VAT on fees. The Facebook Marketplace row covers shipped orders only, because Meta’s pages do not confirm a fee for local pickup.
How this tool works and where the numbers come from
For each platform the page searches for the smallest price, to the cent, at which that platform’s fee engine leaves your goal (a profit amount, a margin on sales or a return on cost) after your item cost, postage and packaging. Fee brackets can make the curve step, so the search checks the cents just below the answer. It does not estimate what the item is worth: check sold listings on the platform for that.

Frequently asked questions
Does the calculator include shipping costs?
Yes, in two places. Your own postage and packaging are costs that your profit is measured against. Shipping you charge the buyer is added to the order, and platforms that take a fee on shipping count it.
What is a good profit margin when reselling?
The sources behind this page set no benchmark, and the right figure depends on how fast the item sells and how much time it takes. Try the same item at 20%, 30% and 40% under “A profit margin (%)” and compare the prices with sold listings.
Why does the price change between platforms?
Fee rules differ: Poshmark takes 20% from $15, Mercari 10%, and Depop only payment processing in the US. The same goal therefore needs a different price on each.
Do fees change my selling price?
Yes, because most fees are a percentage of the price you set. A higher price raises the fee, so you cannot just add the fee to your cost. The tool solves for the price that leaves your goal after the fee has been taken.
How accurate are the results?
The rates were checked against each platform’s pages on 2026-10-28, and changes are listed in the rate changelog. Promotions, seller levels and Store plans are not applied. The results are planning figures, not tax or legal advice.
