About this calculator
Set the net margin you want and this tool reverse-calculates the listing price you need given product cost, marketplace fees, planned ad spend and returns. It also returns a break-even floor and shows the gap vs your current price.
How to use
- Load a scenario preset for default fee structure.
- Enter target net margin and current sale price for comparison.
- If the suggested price is much higher than the market price, look at COGS and ads first, not pricing.
- Use the break-even floor as the absolute minimum during clearance.
FAQ
Why is my suggested price absurdly high?
Variable percentage fees (referral + ads + returns) sum too close to 1 in your inputs. Cut one of them or reduce target margin.
What's the relationship to break-even price?
Break-even price covers all costs at zero profit. Suggested price covers costs plus your target margin.
Should I include FX volatility?
If you settle in a different currency, add a 1–3% buffer to Other Variable Cost.
How do I price a bundle?
Sum component costs and choose a blended target margin. Bundles tolerate higher referral % thanks to higher AOV.
Is this the same as keystone pricing?
Keystone is a heuristic (price = 2x cost). This tool gives the exact price needed for a chosen margin under realistic marketplace fees.
Should target margin equal gross or net margin?
We solve for net — input is the margin AFTER ads and returns, which is what your P&L cares about.
