How auction seller fees are calculated

The auctioneer normally deducts the agreed selling costs from the sale proceeds before paying the balance to the seller.

Net proceeds = hammer price − seller's commission − VAT − other seller fees

Auction fees for sellers: what to check

Ask the auctioneer to set out every charge in writing and clarify whether each quoted figure includes or excludes VAT.

Seller's commission

The auction house's fee for selling the lot, often calculated as a percentage of the hammer price. A minimum commission may apply.

VAT on fees

VAT may be added to the seller's commission and to other services. Enter the VAT rate stated in your agreement.

Entry and marketing

Catalogue entry, photography, illustration, online listing and advertising may be charged separately from commission.

Unsold or withdrawn lots

Some agreements include charges if a lot does not sell or is withdrawn. These are not reflected unless you enter them under other seller charges.

What does it cost to sell a house at auction?

For a property sale, include the auctioneer's commission and VAT plus any entry or administration fee, marketing package, legal-pack preparation and conveyancing costs. Check the seller's agreement for withdrawal or unsold-property charges and whether any fee is payable on exchange rather than completion. Use the calculator above for the charges you know; ask the auctioneer and your solicitor for the rest.

Common questions

What fees does a seller pay at auction?

A seller may pay commission on the hammer price, VAT on that commission, entry or catalogue fees, photography or marketing costs, insurance, transport and other charges in the auctioneer's terms. Charges vary, so ask for a written seller's agreement before consigning an item.

How is auction seller's commission calculated?

Seller's commission is commonly calculated as an agreed percentage of the hammer price. VAT may then be added to the commission. The percentage, minimum charge and any separate fees depend on the auctioneer and sale.

What does it cost to sell a house at auction?

Property auction costs can include the auctioneer's commission, VAT, entry or administration fees, marketing, legal-pack preparation, conveyancing and other charges in the seller's agreement. Check whether fees apply if the property is withdrawn or does not sell.

Do I pay an auction fee if my item does not sell?

It depends on the seller's agreement. Entry, catalogue, photography, transport, insurance, withdrawal or unsold-lot charges may still apply even when there is no sale. Check the reserve and unsold-lot terms before consigning.

Is seller's commission the same as buyer's premium?

No. Seller's commission is deducted from the seller's proceeds. The buyer's premium is added to the winning bidder's hammer price. An auction house may charge both parties.
