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.) For example, if you want an item with a current price of $11, then you must bid at least $11.50 (See also automatic bidding.)
The table below shows the required bid increments for Yahoo! Auctions.
| Price of Item | Increment |
| $0.01-$0.99 | $0.05 |
| $1.00-4.99 | $0.25 |
| $5.00-24.99 | $0.50 |
| $25.00-99.99 | $1.00 |
| $100.00-249.99 | $2.50 |
| $250.00-499.99 | $5.00 |
| $500.00-999.99 | $10.00 |
| $1,000.00-2,499.99 | $25.00 |
| $2,500.00-4,999.99 | $50.00 |
| $5,000.00 and up | $100.00 |
The bid increment can't be changed by the seller or the bidder. The bid increment is only changed as the current high bid increases.
To place a bid over $500.00, you have to sign up for Yahoo! Wallet.
