Reseller calculators
Every one of these answers a question you would otherwise guess at: what a sale nets after fees, what postage will cost before you list, and whether an item is worth buying once its condition is priced in. They run in your browser, they need no account, and the fee schedules are dated so you can see which rates a result used.
The tools
- eBay fee calculator
Every eBay fee on one sale, itemised, including the ones sellers forget.
- Measurement and size converter
US, UK, EU and JP sizing, plus where on the garment each measurement is taken.
Common questions
- Are these calculators free?
- Yes, all of them, with no account and no signup. They run in your browser and nothing you type is sent anywhere.
- How current are the fee rates?
- Each fee schedule carries the date it took effect, and the calculator states which schedule produced your result. When a marketplace changes its rates, the schedule is updated and the effective date moves with it.
- Why does the profit calculator ask for a condition grade?
- Because condition is the largest single lever on resale price, and a comp taken from a mint example will overstate what a worn one sells for. The calculator adjusts the estimated sale price for the grade you enter and shows the adjustment it applied rather than folding it into the total.
