How to price your products for profit on any marketplace (2026)
Last updated June 2026 · ~6 min read
Most sellers price by gut — then wonder where their profit went after fees and shipping. Here's the simple, repeatable formula that bakes in every cost and your target profit, so the number you set is the number that actually works.
The mistake almost every new seller makes is pricing off their cost instead of their take-home. You buy something for $8, add a markup, list it for $20 — and forget that the marketplace takes a percentage of that $20 (plus the shipping the buyer pays), payment processing takes another slice, and you still have to pay for the item and the label. What felt like a $12 profit can quietly become $3, or less.
The fix is to price backwards from the profit you want.
The pricing formula
Why divide by (1 − fee %) instead of just adding the fee? Because the fee is a percentage of the final price, not of your cost. If you simply added 15% to your costs, the platform's 15% of the higher selling price would still leave you short. Dividing "grosses up" the price so your target profit survives the fee.
A worked example
Say you're selling on a marketplace that takes about 13% all-in, your item cost you $8, the shipping label is $4, and you want $10 profit:
List at $25.29 and the math holds: the 13% fee is ~$3.29, leaving $25.29 − $3.29 − $8 − $4 = $10.00 profit. Round up to $25.99 and you've got a small buffer for returns.
The five-step pricing checklist
- Total your true costs. Product + inbound/label shipping + packaging + any per-unit ad spend. Don't forget returns — many sellers reserve 2–5%.
- Look up your marketplace's real fee. Commission + payment processing + any fixed per-order fee. Rates run from ~3% (Bonanza) to 20% (Poshmark) — see which marketplace has the lowest fees.
- Pick a target profit or margin. A dollar amount per sale, or a % of the price (see typical margins below).
- Solve for price with the formula above.
- Check your break-even — the price where profit hits $0. Never list below it. Our calculators show this automatically.
What margin should you aim for?
- Print-on-demand & retail arbitrage: 20–40% net is typical — base costs and shipping eat a big share, so price with discipline.
- Handmade, branded, or private-label: 40–60%+ is achievable because your cost base is lower relative to perceived value.
- Fast-moving resale (thrift flips, sneakers): 15–25% can work if it sells quickly and you're doing volume.
Margin is profit ÷ price. To hit a target margin m, the formula becomes Price = Costs ÷ (1 − Fee% − m).

Frequently asked questions
How do I price a product to make a profit?
Add your true costs (product, shipping, packaging, ads) to the profit you want, then divide by 1 minus the marketplace's total fee rate: Price = (costs + desired profit) ÷ (1 − fee %). Dividing by (1 − fee) is what makes the profit survive the platform's cut.
Why can't I just add a markup to my cost?
Because fees are taken from the selling price, not your cost. A flat markup ignores that the platform's percentage grows with the price (and often applies to shipping too), so your real margin ends up smaller than you planned — sometimes negative.
What's a break-even price?
The price at which your profit is exactly $0 after all fees and costs. It's your floor — price above it to make money. Every Sellculate calculator shows it.
Should I offer free shipping?
Often yes for conversions, but build the shipping cost into the price — and remember most marketplaces charge their fee on that higher price too. Run it through the calculator both ways to see which nets more.
