RapidResell AIFree tools for online sellers
Quick calculators for the numbers that decide whether a listing is worth it. They run entirely in your browser: no signup, nothing sent to a server.
Profit & margin calculator
Net profit, gross margin, markup, break-even price and break-even sales volume after marketplace fees, shipping and ad spend.
Discount & pricing tier optimizer
Test 5–50% markdowns and see the deepest discount you can run before a promotion eats your profit.
Printable eBay listing checklist
A ten-point pre-publish checklist to run through before every listing goes live.
Using these tools in your own workflow
Every calculator starts from an example fee schedule for eBay, Etsy, Shopify Payments, Stripe or PayPal. Fees change and vary by category, so treat the presets as a starting point and type in the rates on your platform's current fee page. Editing a rate switches the tool to custom fees.
The numbers are only as good as your price. If you're unsure what an item really sells for, check sold listings first. Our guide to researching sold comps walks through it.
RapidResell AI identifies the item from a photo, prices it against real sold comps, and publishes to eBay.
