Terms of Use

By accessing or using NumExact, you agree to these Terms of Use. If you do not agree, please do not use the site.

Informational purposes only

NumExact provides calculators and estimates for informational purposes only. They do not constitute financial, tax, legal, or medical advice. Figures are based on published sources as of the date shown on each page, and results may vary with changes in tax rates, policy, exchange rates, your personal circumstances, or subsequent data updates. They should not be the sole basis for tax, investment, medical, or legal decisions — consult a qualified professional for decisions specific to your situation.

No warranty

While we work to keep our data accurate and current — federal tax figures come from IRS publications and are verified against primary sources — the service is provided on an “as is” and “as available” basis. To the maximum extent permitted by law, we make no express or implied warranty as to the accuracy, completeness, timeliness, or fitness for a particular purpose of any result.

Acceptable use

You may use NumExact and the results it produces for any lawful purpose, personal or commercial. You agree not to:

• integrate the NumExact service into your own or third-party applications without our written permission;
• interfere with the operation or security of the site.

The content, design, and code of NumExact — including but not limited to text, interface, code, trademarks, data structures, and calculation logic — are owned by us.
