These terms describe the practical limits of using FairSpend. Last updated September 22, 2026.
Using the tools
FairSpend provides free informational calculators and related guides for comparing purchase costs and planning shared payments. You may use the site for lawful personal or business planning. Enter only information you have the right to use, and avoid placing sensitive financial credentials or private identity details in the contact form.
Check important decisions
Results depend on the values and assumptions you enter. FairSpend does not fetch live retailer offers, verify discounts, calculate every local tax rule, determine legal obligations or transfer money. Fees, promotions, package contents and agreements can change. Confirm a final amount with the seller, receipt or participants before purchasing or paying. Nothing on the site is individualized financial, tax or legal advice.
Availability and external links
We try to keep the calculators available and accurate, but may correct, update or temporarily interrupt the service. Links to independent websites are supplied for context; their offers and practices are their own. FairSpend does not claim an endorsement from those sites.
Content and contact
FairSpend’s original explanations, layout and calculator code are provided for use on this site. Do not misrepresent copied materials as ours or use the service to interfere with other visitors. If you find an error, contact us through the contact page. Our Privacy Policy explains how site data is handled, and our Calculation Methods page explains how results are computed.
