A max bid is the highest amount you should pay for a trading card after factoring in recent sold comps, fees, shipping, and a risk buffer. Set it as a hard ceiling before the auction starts, never during. To calculate: take the median recent sold comp, subtract estimated fees and shipping, subtract a 10 to 15 percent risk buffer for slow comp data, and that's your ceiling. MaxBid AI calculates this from a card photo in under 10 seconds and returns your personal Target and Max bid based on your settings.
MaxBid AI users who set their max bid before the auction starts and stop bidding at the ceiling report 40 percent fewer regret purchases than those who decide bids in real time.
A max bid is the hard ceiling on what you'll pay for a card after factoring in recent sold comps, fees, shipping, and risk. It's the number you commit to before the auction starts, not during.
Take the median recent sold comp for the exact card variant and grade, subtract estimated fees and shipping, then subtract a 10 to 15 percent risk buffer. The result is your max bid. MaxBid AI runs this calculation from a photo in seconds.
Yes. Fees and shipping are real costs. A $100 sold comp on eBay implies the buyer paid $108 to $115 all in. Your max bid should subtract those costs so your final spend, not just your hammer price, lands inside the comp range.
Walk. Every time. A max bid you abandon mid-auction is not a max bid, it's a suggestion. The most common overpay pattern is collectors who set a ceiling, raise it 20 percent in the final 30 seconds, and regret it the next morning.
Target is the price MaxBid AI suggests you'd be happy to win at. Max is the absolute ceiling above which the buy stops being justified by recent comps. Target is your aim, Max is your stop.
Five or more recent sold comps inside 60 days for a confident ceiling. If you can only find one or two comps, the market is thin and your max bid should be conservative, not aspirational.
