Projected current-bid outcome
Formula used
Max bid = adjusted resale value minus desired profit, fixed costs, selling fees, and safety buffer, then adjusted for buyer premium.
Estimates are planning numbers only. Real resale value depends on item condition, demand, time, fees, and cleanup surprises.
Bid smarter. Stop sooner.
Use the estimate to make a clear bidding decision before the auction heats up.

A max bid is not just a guess. It is a stop point based on resale value, fees, cleanup costs, and the profit you need for the risk.
Start with the estimated resale value, reduce it by your confidence level, then subtract desired profit, buyer premium impact, selling fees, cleanout costs, and a safety buffer. The remaining amount is the highest bid that still protects the deal.
Auction photos rarely show everything. A confidence factor lowers the resale estimate for unknown item condition, missing parts, slow-selling inventory, or hidden trash. It helps keep the bid grounded instead of optimistic.
Yes. Buyer premium is part of your actual acquisition cost. If a platform charges an 18% buyer premium, a $500 winning bid can become $590 before fuel, dump fees, supplies, or selling fees are included.
The profit calculator answers what a unit may earn after you enter a bid. The max bid calculator works backward from resale value and target profit to show the most you should bid before the deal stops making sense.
