What this calculator does
Compare three channels on a consistent order value and fulfilment cost. Enter each channel’s actual fee schedule and spread its monthly subscription over an expected order count. The starting rates are illustrative scenarios, not verified Etsy, Amazon, eBay or Shopify pricing. Use the same revenue basis for a fair comparison.
Formula, assumptions and sources
Defaults are illustrative, not current platform rates. Fees = revenue × rate + fixed fee + subscription ÷ orders. Use comparable fee bases and account for shipping and fee taxes.

Frequently asked questions
Does this fetch live marketplace fees?
No. You supply the rates. This avoids assuming one fee schedule applies to every country, account or product category.
Why does order volume affect the comparison?
A monthly subscription divided over more orders adds less cost to each order. Percentage and per-order charges do not change for that reason.
