# Buyer's premium comparison

Pick two or three auction houses and platforms and compare the buyer's premium, bidding formats and shipping help each publishes. For a given hammer price, run the total-cost calculator next.

Use the tool on the [web page](https://auctionfinder.fyi/tools/compare-auction-houses). It works without JavaScript.

## How to use it

1. Pick 2 to 3 auction houses and platforms.
2. Read the side-by-side table.

## How it works

Every row is a listing in this directory. The buyer's premium is the first-tier percent the house publishes; the tiers and thresholds sit in the premium details row.

A blank cell means the listing does not state that detail; a blank is shown rather than a guess.

To compare total cost for one hammer price across houses, use the auction total-cost calculator with each house's premium.

Published schedules cited: Christie's buyer's premium (christies.com), Heritage terms (ha.com/c/ref/terms-and-conditions.zx), Sotheby's premium help (help.sothebys.com) and Catawiki's Buyer Protection fee (catawiki.com). Bonhams shows no premium: its published schedule is for the United States and the listing is in London.

## Questions

### How many auction houses and platforms can I compare?

You can compare two or three at a time.

### Why is a premium cell blank?

A blank means the house does not publish a buyer's premium, or an editor has not yet cited it. Never assume it is zero — ask the house before you bid.

Buyer's premiums, bidding rules and payment terms come from the source named on each listing and were last checked on the date shown; they change, so confirm them with the house or program before you bid or pay. Beware of auction fraud and shill bidding: never wire money or pay by gift card to a seller you cannot verify, and walk away when a price is run up by a bidder who never buys.
