Auction Terms Explained: From ‘Reserve’ to ‘Hammer Price’
29th Jul, 2025
Online auctions are becoming the go-to platform for businesses and individuals looking to buy or sell assets across South Africa. Whether you're bidding on earthmoving equipment, vehicles, or liquidation stock, understanding the terminology used during an auction is essential.
At WCT Auctions, we believe that informed bidders make confident decisions, and this glossary of key auction terms will ensure you’re one step ahead.
What Is an Auction?
An auction is a public sale where goods or assets are sold to the highest bidder. At WCT Auctions, our platform facilitates timed online auctions across multiple categories, including construction equipment, mining assets, trucks and trailers, and salvage stock, making it easier than ever to buy and sell anywhere in South Africa.
Key Auction Terms You Should Know
Reserve Price
The reserve price represents the lowest amount a seller is prepared to accept for their item.
At WCT Auctions, some lots may carry a reserve price clearly indicated in the item listing to ensure the seller’s interests are protected. If no bids reach the reserve, the seller has the right to withdraw the item or negotiate post-auction.
Opening Bid
This is the starting bid at which the auction begins. It is set by the auctioneer and does not necessarily reflect the item's value or reserve. It simply encourages participation and sets the tone for bidding activity.
Hammer Price
The hammer price is the final accepted bid when the auction closes, literally when the metaphorical hammer “falls.” This is the price the winning bidder agrees to pay, excluding applicable VAT, commission, or administrative fees.
???? Tip: Always review the full breakdown of costs after the hammer price. At WCT Auctions, these details are outlined in each lot’s Terms & Conditions section to ensure transparency.
Buyer’s Premium
A buyer’s premium is an additional fee added to the hammer price, typically expressed as a percentage. It covers the auctioneer’s services and contributes to running the online auction platform.
WCT Auctions maintains a competitive and clear buyer's premium structure disclosed upfront to avoid surprises.
Lot Number
A lot refers to the item or group of items available for bidding. Each is assigned a lot number, which helps buyers identify, track, and query listings easily throughout the auction process.

Subject to Confirmation (STC)
Sometimes, items are marked as "STC – Subject to Confirmation" after the auction ends. This means that even if you placed the highest bid, the final sale is still pending the seller’s confirmation. This typically applies when the bid has not met the reserve price, and the seller needs to decide whether to accept the offer or not.
