Expy Profit Calculator

Multi-currency support handles cross-border listings, and you can override any fee when a platform updates its schedule before the preset does.

A profit calculator that tells you what actually lands in your bank.

If you sell on Etsy, eBay, Amazon, Shopify, Depop, Poshmark or Mercari, you already know the headline price is a lie — transaction fees, payment processing, listing fees and shipping quietly redraw the number on the way to your account. Expy Profit Calculator is the calm, offline margin calculator built for sellers who would rather see the real figure before they list than discover it on a payout report.

Enter your cost and sale price, pick the marketplace, and the app applies that platform's real fee structure to return true profit, margin percentage and break-even price in a single view. A markup calculator works in reverse from cost to target price, comparison mode shows which platform nets you the most for the same item, and saved products with fee templates let you re-run pricing for a whole shop in seconds. Multi-currency support handles cross-border listings, and you can override any fee when a platform updates its schedule before the preset does.

This Etsy fee calculator and reseller tool runs entirely offline, so your product pricing stays on your device — no accounts, no analytics, no fee data sold back to the platforms charging you. Quick-calc widgets sit on the Home Screen for one-tap margin checks between listings, the interface ships in 39 languages with full VoiceOver support, and the pricing calculator stays focused on one quiet job: making sure the seller calculator on your phone agrees with the bookkeeper at the end of the year.
