Buyer's premium

Buyer's premium: A percentage an auction house adds to the winning bid, paid by the buyer.

How we measure it

We record the rate from the venue's fee page, and from the lot's own notice when it prints one.

What it is not

A hammer price without the premium understates what the buyer paid.
