What "Buyers" means
Fees aren't everything: a cheaper platform with fewer buyers can mean waiting weeks or taking a lower price. The Buyers rating is our estimate of how many active buyers each platform has for that kind of item, from Very high to Low. It's a judgment call, not official data. Local pickup depends entirely on where you live, so it's marked that way. For items worth $500 or more, the calculator suggests trying fee-free local pickup first and falling back to the best shipping platform after two weeks.
Fees last checked November 5, 2026. Platforms change fees often, and promotions, store subscriptions, payout methods and taxes can change your real number, so treat this as a close estimate. Everything is calculated in your browser; nothing you type is saved.
