What should I list it for?
Start with the profit you want. Get the price to list at on each platform, with room for offers.
List price calculator →Lot cost calculator
Bought a box or bin for one price? Split the cost across every item inside, evenly or by value.
Split a lot →Fee comparison
One sale, every platform: see the fee and what you keep, ranked from most to least profit.
Compare fees →Why work backward from profit?
Most fee calculators tell you what's left after you pick a price. Resellers usually need the opposite: the price that still leaves the profit you want once fees, shipping, and offers take their cut. The list price calculator does that for every platform at once.
Why split a lot?
When ten items came out of one $40 box, each one's cost is a share of that $40. Without splitting it, cheap items look like losses and good finds look like pure profit. The lot cost calculator gives each item a fair share you can copy into your records.
