Start with resale evidence
Use a defensible expected resale figure for the exact item, condition and bundle.
This calculator helps resellers set a ceiling from resale proceeds, expected costs and target profit. It does not place bids or guarantee resale value.
This is a planning ceiling, not a valuation or bidding instruction. If resale evidence is weak, use a more conservative expected resale value or require more profit headroom.
The calculator keeps the arithmetic separate from the live bid. Your expected resale value, costs and required profit determine the ceiling.
Use a defensible expected resale figure for the exact item, condition and bundle.
Selling costs, outbound postage, cleaning, repairs and other costs all reduce the safe purchase ceiling.
Resell AutoBot does not place bids. The calculator provides decision support only.
Resell AutoBot can track auction state alongside current-market resale evidence so you can judge your own maximum sensible bid without handing control to an auto-bidder.
