Consignment Payout Calculator
Auction houses typically charge consignors a 15–35% seller's commission on the hammer price, sometimes plus per-lot fees. A $1,000 sale at 25% commission nets you $750 — the buyer's premium is paid by the bidder and, at most houses, doesn't touch your payout. Enter your numbers to see both sides of the deal.
Typical range: 15–35%. High-value consignments often negotiate lower.
Shown so you can see the house's full economics — it doesn't reduce your payout at most houses.

Is 25% commission fair?
It's the middle of the typical 15–35% range. What matters is the all-in effective rate this calculator shows — commission plus fees — and what the house does for it: marketing reach, cataloging quality, and realized prices.
Why show the house's side?
Honest math builds trust in both directions. The house earns commission plus the buyer's premium — knowing the full economics helps you negotiate and helps good auctioneers explain their value.
