How it is calculated

Margin here means net profit ÷ order base, where order base = selling price + shipping charged. The tool solves: order base − product cost − shipping cost − platform fees − (Shopify subscription ÷ orders, for Shopify only) = target margin × order base. It searches for the smallest order base that satisfies it, then subtracts shipping charged to give the selling price. If the platform's percentage fees already exceed 100% − target margin, no price can reach the target, and the tool says so instead of inventing a number.

Worked example (defaults): Canada, Etsy, cost $15, shipping cost $6, shipping charged $8, target 40%. Etsy percentage fees total 10% (6.5% transaction + 3% processing + 0.5% regulatory). Order base = ($15 + $6 + $0.20 listing + $0.25 processing fixed) ÷ (1 − 0.10 − 0.40) = $21.45 ÷ 0.50 = $42.90. Selling price = $42.90 − $8 = $34.90. Check: fees $4.74, net $42.90 − $15 − $6 − $4.74 = $17.16 = 40% of $42.90.

What this tool does NOT include — read before deciding

Discovery: marketplaces bring their own search traffic; your own store does not. A fee saving does not pay for the traffic you would need to replace.
Customer acquisition cost (CAC): not included unless a tool says so. Paid traffic can erase a fee saving — run the numbers with your real CAC.
Refunds and returns: not modelled unless a tool says so. Some platforms keep part of the fee on a refund; return shipping and restocking are extra.
Apps and plugins: your own store's apps, themes, and tools are not in the Shopify Basic subscription shown here.
Taxes: sales tax / VAT is excluded from the fee base. eBay Germany figures exclude 19% USt.
Fulfilment and storage: no FBA, 3PL, warehouse, or storage fees are included for any platform.
Currency conversion, international fees, and category variations: not modelled. Most-common category rates are used; your category may differ — check your seller dashboard.

Why Amazon is not compared — explicit exclusion

Amazon is not in this tool, deliberately — not an oversight and not a “coming soon” badge. Amazon referral fees vary by category (roughly 8% to 45%) and FBA fees depend on size and weight, which this tool does not collect, and Amazon’s Seller Central schedule is login-gated and could not be verified from an official page. No Amazon numbers are shown rather than guessed ones. See the Fee Index for exactly what is missing.
