Terms and Conditions
By using AuctionMath, you agree to these Terms and Conditions. If you do not agree, please do not use the site.
Use of the Calculator
The buyer's premium confirmation, invoice, bid ceiling, and seller net tools are provided as a convenience for reviewing auction math from the inputs you provide. Results depend on the amounts, percentages, bid increments, taxes, shipping costs, seller costs, and other assumptions you enter, and may not reflect every auction house's rules, rounding method, tax treatment, fees, commissions, or payment terms.
The historical exchange rate calculator is provided as a convenience for estimating currency conversions using reference data from third-party providers. Results may not match the rate used by a bank, payment processor, credit card network, auction house, tax authority, shipper, or other service provider.
No Professional Advice
The site does not provide legal, financial, tax, auction, or appraisal advice. You should verify all calculations against the official auction listing, invoice, bidder agreement, or auction house terms before bidding or making a purchase decision.
Accuracy
We try to make the calculators useful and accurate, but we do not guarantee that the site, third-party data, API endpoints, or calculations will be error-free, uninterrupted, current, complete, or suitable for your specific purpose. You are responsible for confirming whether a price includes a buyer's premium under the official auction terms and for verifying invoice totals, bid limits, seller proceeds, exchange rates, and valuation assumptions against appropriate source records.
Advertising
The site may display third-party advertisements. We are not responsible for the content, products, services, or practices of advertisers or third-party websites linked from ads.
Intellectual Property
The site design, text, and calculator interface are owned by Sidequest 29, LLC unless otherwise stated. You may use the calculator for personal or business reference, but you may not copy, resell, or repackage the site as your own service without permission.
Limitation of Liability
To the fullest extent permitted by law, Sidequest 29, LLC will not be liable for any losses or damages arising from your use of the site or reliance on calculator results.
Changes to These Terms
We may update these Terms and Conditions from time to time. Updates will be posted on this page with a new last updated date.
