Auction glossaryAll-In Price: The Real Total You Pay at an Auction
An all-in price is the total you actually pay to win an auction lot: the hammer price plus the buyer's premium, sales tax and shipping, if the lot ships. It's the number that matters for your budget, because the winning bid alone can understate your cost by a fifth or more.
How do you calculate an all-in price?
Work up from the winning bid. Our all-in pricing guide has more examples.
- Start with the hammer price: $240.
- Add the buyer's premium: 18% is $43.20, for $283.20.
- Add sales tax: at 8.25%, that's $23.36, for $306.56.
- Add shipping if the lot ships; a pickup lot adds nothing here.
How does Auktia show all-in prices?
Auktia can show every price all-in, computed on the live bid as it changes. Every item page shows the all-in total before you bid, and the All-in pricing switch in the header shows every price that way. The bid you place is the cost you accept. See how all-in pricing works.
Questions people ask
Is the all-in price the same as the hammer price?
No. The hammer price is just the winning bid; the all-in price adds everything else you'll owe.
Do I pay sales tax on the buyer's premium?
In Texas, generally yes, since the premium is part of the sales price. If you buy for resale with a valid certificate, tax may not apply; check with the Texas Comptroller.
