How this is calculated
This tool doesn't introduce a separate pricing formula. It takes the target margin you enter and searches for the sale price at which this site's existing Amazon FBA, Etsy, Shopify, eBay, or Stripe/PayPal calculator reports that exact margin — narrowing in on the answer the same way you'd do it by hand, trying prices until the number matches. That keeps this tool's numbers permanently in sync with each platform's calculator: there's no second copy of the fee math to drift out of date.
Every fee structure with a percentage-based fee has a ceiling margin it approaches but never reaches, since a percentage cut never fully disappears no matter how high the price goes. If your target is at or above that ceiling, the tool reports it as unreachable and shows you the actual ceiling instead of a misleading price.
Sources
Every figure traces back to the individual platform calculator running underneath — Amazon FBA, Etsy, Shopify, eBay, and Stripe & PayPal — each with its own cited primary source and "last reviewed" date.
Scope & limitations
Margin here means the share of the sale price left after platform and payment-processing fees — it does not subtract your cost of goods, ads, or other overhead. Amazon is scoped to Small/Large Standard-Size items up to 20 lb, matching the standalone tool. Shopify assumes Shopify Payments with no monthly-order subscription amortization. Sales tax isn't modeled. Treat the price this tool returns as a fee-driven floor, not a full pricing strategy — competition, perceived value, and demand also set what you can actually charge.

Frequently asked questions
How is this different from the regular fee calculators?
Every other calculator on this site takes a sale price and tells you the margin it leaves. This tool runs that backwards: you enter the margin you want, and it finds the sale price that produces it — searched against the same fee engines, not a separate formula.
Why does it say a target isn't achievable?
Percentage-based fees (Amazon's referral fee, Etsy's transaction fee, Shopify's processing rate, eBay's final value fee) take a fixed cut no matter how high the price goes, so every fee structure has a ceiling margin percentage it can never exceed. If your target is above that ceiling, no price — however high — will reach it, and the tool tells you the actual ceiling instead.
Why does it say the target is already met at $0?
This can happen on Etsy, Shopify, and eBay if you've entered a shipping charge: because those platforms' fees are calculated on item price plus shipping, a shipping charge alone can already cover a low fixed-fee target before you charge anything for the item. Raise your target margin or lower the shipping charge to see a real price threshold.
Does this account for my cost of goods?
No — like every calculator on this site, "margin" here means the share of the sale price left after platform and processing fees, not profit after your cost of goods, ads, or overhead. Subtract your own costs from the price this tool returns to get true profit.
