Terms of Service

Effective: May 2026

Using DuckDollar

DuckDollar is a free, publicly accessible collection of finance calculators and educational tools. You're welcome to use them for personal, educational, or planning purposes. No account is required.

You may not use this site for any unlawful purpose, to harvest content for competing services, or in any way that could harm the site's availability for other users.

Not financial advice

The tools on DuckDollar are for educational and informational purposes only. They are not a substitute for advice from a licensed financial, tax, or legal professional.

Results are estimates based on the inputs you provide and the formulas documented on each tool's page. Your financial situation involves details a calculator cannot know — your specific tax filing status, deductions, investment risk tolerance, employer terms, and more. Use these tools to get a clearer picture of your numbers, then consult a qualified professional before making significant financial decisions.

No warranty

DuckDollar provides these tools "as is." We work to keep the formulas accurate and the tools functional, but we make no guarantees about the accuracy, completeness, or fitness of any tool for any particular purpose. Tax laws and interest rates change. We aim to keep tools current but cannot guarantee they reflect the latest rules at all times.

Limitation of liability

DuckDollar and its operators are not liable for any financial loss, missed opportunity, tax penalty, or other damage resulting from your use of — or reliance on — any tool or content on this site.

Third-party links

Some pages may reference or link to external websites. We're not responsible for the content, accuracy, or privacy practices of those sites.

Changes

We may update these terms as the site grows. The effective date at the top reflects the latest revision. Continued use of the site after changes constitutes acceptance of the updated terms.
