Auction Fee Structure

Buyer Pays: Hammer Price + Buyer's Premium (tiered: 26% up to $1M, 20% $1-6M, 14.5% over $6M)

Seller Receives: Hammer Price - Seller's Commission (5-15%) - Insurance (1-2%) - Catalog Fee

Total Transaction Cost: Buyer's Premium + Seller's Commission = 20-40% of hammer price

Frequently Asked Questions

What is a buyer's premium and why does it exist?
The buyer's premium is an additional charge paid by the buyer on top of the hammer price. At major houses, it is typically 26% on the first $1 million, 20% on $1-6 million, and 14.5% above $6 million. It was introduced by Christie's in 1975 as an additional revenue source. All major auction houses now charge it. It is not negotiable for buyers.
Can seller's commissions be negotiated?
Yes. Seller's commissions are highly negotiable, especially for high-value consignments. Standard rates are 10-15%, but major consignors with $1M+ lots can negotiate down to 5% or even 0% commission. Auction houses may also offer guarantees (minimum prices) and enhanced marketing packages to attract desirable collections.
What happens if my lot does not sell?
If your lot fails to sell (called "bought in"), you may owe a buy-in fee of 5-10% of the low estimate. This covers the auction house's catalog, marketing, and handling costs. Some houses waive this fee for valuable consignments. A bought-in lot can be difficult to sell subsequently as the failed auction becomes part of the work's public sales record.
Is it better to sell at auction or through a gallery?
Auction provides price transparency and access to global bidders, but total fees (buyer's premium + seller's commission) can consume 25-40% of the total transaction. Gallery private sales charge 10-20% commission but may achieve higher prices through targeted marketing to specific collectors. Private sales also offer discretion, which some collectors prefer.

Understanding Art Auction Economics

Auction houses operate on a dual-commission model, collecting fees from both buyers and sellers. The total transaction cost can be 25-40% of the hammer price. Understanding these fees is essential for making informed decisions about when and where to sell art. For sellers, the choice between auction and private sale depends on the artwork, timing, and desired outcome.
