Free profit calculator app for Etsy & Shopify sellers
An Etsy calculator app, Shopify profit calculator and eBay fee calculator in one: 19 free tools on your home screen, including TikTok Shop, PayPal fees, ROAS and pricing. Works offline for calculators you've used.
Why use a profit calculator app?
Most pricing decisions don't happen at a desk. You're at a thrift store deciding whether a jacket is worth reselling, at a craft fair working out a bundle price, or messaging a supplier about a new product. A profit calculator app on your phone answers the only question that matters in seconds: how much will I actually keep after every fee?
- Price before you list. Check the net profit and break-even price of a product before it goes live.
- Source with confidence. At a thrift store or wholesaler, see whether an item leaves enough margin after Poshmark, Mercari, eBay or Etsy fees.
- Plan sales and ads. Test a discount or work out your break-even ROAS while you're setting up a campaign.
- Works with weak signal. Calculators you've opened before still work offline.
Etsy calculator app
The Etsy fee calculator in the app uses 2026 rates: a $0.20 listing fee, a 6.5% transaction fee on the item and shipping, payment processing and optional Offsite Ads. Enter your price and costs to see your Etsy profit, margin and the lowest price that still makes money. UK sellers can switch to pounds and UK rates.
Shopify and eBay profit calculator app
Switch to the Shopify fee calculator for Shopify Payments rates on Basic, Grow and Advanced, third-party transaction fees and plan costs per order, or to the eBay fee calculator for the 13.6% final value fee and Promoted Listings. The comparison table shows the same product on Etsy, Shopify and eBay side by side.
Calculator app for resellers and social sellers
Resellers get fee calculators for Poshmark, Mercari and Depop, and social sellers get a TikTok Shop fee calculator with creator commissions. There are also PayPal and Stripe fee calculators, a margin and markup calculator, a ROAS calculator and a VAT calculator.

Frequently asked questions
Is there an Etsy calculator app?
Yes. The free Ecom Profit Calculator app for Android includes an Etsy fee calculator with 2026 rates: the $0.20 listing fee, 6.5% transaction fee, payment processing and Offsite Ads. It shows your Etsy profit, margin and break-even price for every listing.
Is there a free Shopify profit calculator app?
Yes. The same app includes a Shopify fee and profit margin calculator with Shopify Payments rates for each plan, third-party transaction fees and plan costs per order.
What should a good profit calculator app include?
Every fee your platform charges, including fees on shipping, plus your product, shipping, packaging and ad costs. It should show net profit, margin and the break-even price, not just the fees. This app does all of that for Etsy, Shopify, eBay, TikTok Shop, Poshmark, Mercari and Depop.
Is the profit calculator app free?
Yes. The app and every calculator in it are free, with no sign-up.
Why does my phone warn me before installing?
Android shows a warning for any app installed from outside the Google Play Store. The app is this website packaged for Android, and you only need to allow installs from your browser once.
Do I need to update the app?
Rarely. The app shows the latest version of the website, so new calculators, guides and fee changes appear automatically.
Does the app work offline?
Calculators you've already opened keep working without internet, which is handy at craft fairs and markets with poor signal.
Is there an iPhone version?
Not as a download, but you can add the site to your home screen: open it in Safari, tap Share, then Add to Home Screen. It opens like an app.
