Buyer’s premium: a plain-language definition
A buyer’s premium is a fee added to the winning bid. If an auction has a 5% buyer’s premium and the winning bid is $200,000, the premium is $10,000, making the bid-plus-premium amount $210,000. Property-specific terms may use a different percentage, a fixed amount, or a minimum premium.
The premium is separate from Auction14’s one-time bidding membership. Membership unlocks bidding access; the buyer’s premium belongs to a particular property transaction and is only relevant if you win that auction.
How to calculate the premium before bidding
Read the property’s premium rule carefully. A term such as ‘5% or $2,500 minimum, whichever is greater’ means a $30,000 winning bid would carry the $2,500 minimum rather than $1,500. A $100,000 winning bid would carry $5,000.
Work backward from your all-in budget. If your maximum for bid plus a 5% premium is $210,000, the bid portion cannot exceed $200,000. Then subtract other expected costs before deciding whether that number still works.
What the buyer’s premium does not include
The premium is not a complete closing estimate. Deposits, transfer charges, title work, legal fees, loan costs, taxes, insurance, repairs, utilities, and other disclosed charges may remain separate. The listing and transaction documents—not a generic calculator—control the actual obligation.
- Winning bid
- Buyer’s premium
- Property-specific fees or deposits
- Closing, title, legal, tax, and financing costs
- Repairs, security, utilities, and holding costs
Use the premium to set a disciplined maximum bid
Enter several possible bid amounts into the property calculator before auction day. Save the all-in total for your walk-away number and leave room for uncertainty. When the auction is moving quickly, you should already know the total cost of the next bid.
