|---|
Sorted by net profit. Rows in green are the best at the numbers you entered. The last column solves the same maths backwards: what you would have to charge on that platform to keep the target profit.
Why the fee basis matters more than the headline rate
A percentage is only half the story. eBay, Etsy, Mercari and Amazon charge their percentage on item plus shipping, so money that only passes through your hands is taxed like revenue. Poshmark's buyer pays the label separately, so its commission falls on the item price alone — and under $15 it charges a flat $2.95 instead, which is brutal on a $10 sale and mild on a $40 one. Fixed charges do the same damage from the other direction: $0.30 or $0.99 per unit sounds trivial until the item is cheap.
The last column is the number most sellers never work out. If you need $20 clear per item, the price is not the same everywhere: a 20% commission platform needs a substantially higher ticket than a card processor does. Pricing from the platform you happen to use first is how good items end up unsellable on one channel and underpriced on another.
What this page does and does not include
It includes each platform's typical percentage and fixed charge, and models Poshmark's flat tier properly. It does not include monthly plan fees (Shopify's $29/month, Amazon's $39.99 Professional plan), Amazon FBA fulfilment, promoted listings, Etsy Offsite Ads, or Gumroad's 30% Discover rate. Those are all on the individual pages, and the ones that repeat monthly are only worth it above a certain order volume — which the Shopify and Amazon pages work out for you.
