This page follows your strongest screenshot messages: real cost, instant calculation, foreign exchange support, tariff awareness, privacy, and simple premium unlock.
What you bid is not what you pay
Auction prices rarely end at the hammer. This app helps you see the full cost before the excitement of bidding makes the math easy to ignore.
Buyer’s premium, tax, shipping, and fees — calculated instantly
Enter the auction details and see the full result immediately, including common post-hammer costs that are easy to underestimate.
Know the real auction cost before you place a bid
The fastest way to avoid regret is to know your real all-in number before you commit to the lot.
Live exchange rates with import tariff if required
International purchases are harder to estimate. Auction Calculator helps account for currency conversion and import-related surprises before they happen.
Avoid surprise bills from FedEx, DHL, and UPS
Duties and import charges can turn a good deal into a disappointing one. Estimate them up front when they apply.
No ads. No tracking. One-time purchase.
The app is designed to solve a problem quickly without clutter, surveillance, or subscription pressure.
Foreign auctions unlock with a one-time payment
Domestic auctions are free to use. Foreign auction tools unlock once, giving access to live exchange rates, tariffs, and multi-currency support.
