IAAI Fees Calculator is an online resource designed to help prospective buyers estimate the costs associated with purchasing vehicles through IAA auctions. Its main tool lets users enter a bid amount and select details such as vehicle type, buyer volume, payment method, and bid type to generate a fee breakdown. Estimates can include buyer, gate, virtual bidding, environmental, title-handling, service, and other applicable fees, helping users consider more than the winning bid when planning a budget.

The site also provides fee comparison tables for standard and high-volume buyers, online and proxy bidding, and higher-value bids. Its guidance covers payment options, payment deadlines, additional charges, salvage-vehicle sales tax, and factors to consider before bidding. Practical tips encourage users to review comparable vehicle sale prices, check auction histories, compare similar vehicles, set a maximum bid, and account for transportation and repair costs. The website links to related calculators and shipping resources, including domestic and international shipping information.
