What is a Buyer Fee %?

The Buyer Fee is one of the ways an auction makes money. A buyer fee (sometimes called a buyer's premium) is an extra cost the buyer pays when they win an auction item. It's a percentage of the winning bid amount that goes to the auction as income.

For example, if the winning bid is $100 and the buyer fee is 15%, the buyer pays an extra $15 on top of their bid.

How Buyer Fees Work

Example with a 15% buyer fee on a $1,000 winning bid:

  • Final hammer price: $1,000
  • Buyer fee (15%): $150
  • Total amount paid by buyer: $1,150

Key Points

  • Standard practice: Buyer fees are common in most auction houses and online platforms
  • Variable rates: Fees typically range from 10% to 30%, depending on the auction house, item category, and sale format
  • Disclosure: Legitimate auctions always disclose the buyer fee percentage before bidding begins
  • Revenue source: Represent a significant revenue stream for auction houses
  • Tax implications: In many jurisdictions, sales tax is calculated on the total amount including the buyer fee

Why Auction Houses Charge Buyer Fees

  • Cover operational costs (staff, facilities, marketing)
  • Offer more competitive seller commission rates
  • Generate additional revenue beyond seller commissions
  • Fund specialized services like authentication, cataloging, and photography

As a bidder, it's crucial to factor in the buyer fee percentage when determining your maximum bid amount, as it significantly impacts the total price you'll pay.
