Any new bid must be greater than the current high bid. The additional amount you're required to bid depends on the price of the item being auctioned. In other words, bid increments are determined by the item's price.

The bid increment can't be changed by the seller or the bidder. The bid increment will only be changed as the current high bid increases.

The table below shows how increments are determined:

Note:
A bidder may be outbid by less than a full increment. This would happen if the winning bidder's maximum bid beats the second highest maximum by an amount less than the full increment.
