Sample Bidding Increment Chart

"Increment bidding" refers to the minimum amount an auction bid must be raised in order to surpass the last highest bid. The increment amounts change when specific bidding thresholds are reached, as outlined in the Bidding Increment Chart for each auction.

Incremental bidding is used in proxy bidding, the process by which an auction house automatically makes incremental bids on behalf of a bidder up to his stated maximum bid.
