Pricing Calculator — Find the Minimum Price That Hits Your Margin
Enter your costs and target profit. The calculator instantly solves for the minimum sale price that covers every cost line and the platform's percentage cut — with an optional safety buffer for fee changes and rounding.
Default uses eBay-style fees (13.35% + $0.40). Change to match your channel — 0% for direct, 6.5% for Etsy, 15% for Amazon, 20% for Poshmark, 10% for Mercari.
How it works
Reverse pricing in plain language
Reverse formula
Price = (item cost + shipping + flat fee + desired profit) ÷ (1 − fee rate). The calculator solves this instantly — the result always covers every cost and the platform's percentage cut.
Any platform
Set the fee rate to whatever your channel charges. eBay: 13.35% + $0.40. Etsy: 6.5% + $0.25. Amazon: 15%. Poshmark: 20%. Mercari: 10%. Direct sales: 0%.
Safety buffer
A 1–5% buffer inflates the price slightly above the minimum. Absorbs rounding tax, fee tier changes, and small shipping increases without eating your margin.
Verify in profit calculator
Once you have a price, plug it into the profit calculator to see the full breakdown — revenue, every cost line, net profit, margin %, and ROI.

The pricing calculator above uses the reverse pricing formula: price = (item cost + shipping + flat fee + desired profit) ÷ (1 − fee rate). The platform's percentage cut means each dollar of price only contributes (1 − fee rate) to your take-home, so the price must always be higher than the sum of costs plus desired profit.
What fee rate should I enter for each platform?
eBay US: 13.35% rate + $0.40 flat. Etsy US: 6.5% rate + $0.25 flat (add 3% processing in the flat fee field for a full picture). Amazon: 15% rate (add FBA cost to item cost). Poshmark: 20% rate. Mercari: 10% rate. Direct / own site: 0% rate. The platform-specific calculators (eBay, Etsy, Amazon) pre-load the exact schedules if you prefer to start there.
Why add a safety buffer?
A 2% buffer adds roughly $0.50 to a $25 listing price — imperceptible to buyers, but it absorbs small fee changes, shipping rate increases, or rounding that would otherwise push you below your target margin. Set it to 0% to see the strict minimum; set it to 5% for a conservative cushion on thin-margin products.
Verify your price in the profit calculator
After getting a recommended price here, paste it into the profit calculator as the sale price. This confirms the realized margin and ROI at that price point, and catches any cost you may have modelled differently between the two tools.
FAQ
Pricing calculator questions answered
How do I calculate the right selling price for a product?
Use: price = (item cost + shipping + flat fee + desired profit) ÷ (1 − fee rate %). The platform's percentage cut means the price must be higher than the sum of costs. The calculator solves this for you with an optional safety buffer.
What is a good profit margin for resellers in 2026?
25–40% net margin is a healthy target. Below 15% leaves very little room for returns, fee changes, or shipping rate increases. Enter your target profit in the Desired profit field and the calculator back-solves the minimum price.
Should I add a safety buffer to my listing price?
Yes — 1–5% is a sensible buffer. The base price solves for an exact profit, but small rounding, fee tier changes, or a $0.10 shipping increase can push you below target. A 2% buffer costs almost nothing to the buyer but pays for itself the first time costs change.
What if my marketplace fees total more than 100%?
Then no finite price can recover your costs — the formula divides by zero. The calculator shows a 'Not feasible' message. Lower the fee rate or remove a cost line to get a solvable result.
How is this different from a markup calculator?
A markup calculator adds a fixed % on top of cost (e.g. cost × 1.5 = price). That ignores the marketplace's percentage cut. This calculator solves for a target profit net of fees — the actual amount that lands in your bank account.
Should I verify the price in another calculator?
Yes — after getting a recommended price here, plug it into the platform-specific calculator (eBay, Etsy, Amazon, etc.) to catch any localized fee you may not have modelled, or into the profit calculator to see the full cost breakdown at that price.
