eBay final value fee
Most categories, up to $7,500 per item, plus $0.40 per order. Fee applies to shipping and sales tax too.
Etsy transaction fee
Plus 3% + $0.25 processing and a $0.20 listing fee. Offsite Ads adds 12% or 15% when it applies.
Amazon FBA fuel surcharge
A 2026 surcharge on top of every FBA fulfillment fee in the US, Canada, and remote fulfillment.
Shopify Basic processing
Plus 30¢ per online sale with Shopify Payments. Third-party gateways add another 2% on Basic.
Rates are US defaults for the most common case. Category exceptions, store subscriptions, and account-level pricing can change the result. How we calculate →
Most fee calculators stop at the headline rate.
That is where the expensive mistakes start. eBay charges its percentage on shipping and sales tax. Etsy stacks three fees. Amazon adds fulfillment, storage, and a fuel surcharge. Shopify has a monthly plan hiding behind a per-sale rate.
FeeNook models the whole stack, shows every line, and lets you override any assumption. No black box, no “contact us for pricing.”
