Cost-to-Win Calculator

This calculator uses the live pricing card values (Special Offer: $10 / credit, 10 credits included) so bidders can estimate the real cost-to-win before placing bids.

Note: Unused credits are non-refundable by default. If AuctionBnB cancels an auction before it closes, credits used for that auction will be refunded.

How to use: enter a conservative estimate of the bids you expect to place. Total cost is calculated as:
(bids × credits-per-bid × cost-per-credit) + final auction price.

Tip: show the bids you've placed in your account, so you can compare actual vs estimated cost after the auction.

Frequently Asked Questions

How do credits work?

Credits are purchased from the Pricing page and used to place bids. Each listing shows how many credits a bid consumes. If not shown, assume 1 bid = 1 credit.

Are credits refundable?

Unused credits are non-refundable by default. If AuctionBnB cancels an auction before it closes, credits used in that auction will be refunded to bidder accounts within 7 business days.

What happens if an item is not as described?

If you win and the item is materially misdescribed, open a dispute. If the dispute is resolved in the buyer's favor, the final payment and credits used in that auction will be refunded.
