Free eBay Seller Tools.
Three focused tools for three different seller decisions: fees, offers and advertising.
Available eBay seller tools
eBay Final Value Fee Calculator
Estimate current basic eBay.com final value fees by category for a known sale.
eBay Best Offer Calculator
Find the lowest offer you can accept while preserving a target net profit.
eBay Promoted Listings Break-even Calculator
Find the maximum General campaign ad rate a sale can absorb before profit reaches zero.
Which eBay calculator should I use?
Use Final Value Fee when the sale amount is already known and you want the platform fee. Use Best Offer when a buyer has made an offer and you need the lowest item price that still preserves a target profit.
Use Promoted Listings Break-even when the decision is advertising: it finds the maximum General campaign ad rate the estimated sale can absorb and lets you test a specific rate. These are separate seller decisions, so the inputs and results are kept separate too.
