Terms & Disclaimer

Last updated: March 17, 2026

By accessing and using NestMath ("we," "us," or "our") at nestmath.com, you agree to the following terms. If you do not agree, please do not use the site.

For Educational Purposes Only

NestMath provides free, browser-based mortgage and real estate calculators for educational and informational purposes only. All results are estimates generated by standard amortization formulas based on the inputs you provide. They do not constitute loan offers, pre-approvals, commitments to lend, or guarantees of actual loan terms, payments, costs, or eligibility.

Not Financial, Legal, or Tax Advice

Nothing on NestMath constitutes financial, legal, tax, or investment advice. We are not a mortgage lender, broker, bank, financial advisor, tax professional, or attorney. We do not recommend specific loan products, lenders, or financial strategies. All educational content on this site is general in nature and should not be relied upon as a substitute for professional advice tailored to your individual circumstances.

Before making any financial decision — including purchasing a home, refinancing a mortgage, or choosing a loan product — consult with qualified professionals who can evaluate your circumstances, credit profile, and financial goals.

Limitations of Calculator Results

Calculator results are approximations. Actual mortgage payments, interest costs, insurance premiums, and other figures will vary based on factors our tools cannot account for, including but not limited to:

  • Your credit score and credit history
  • The specific lender's underwriting criteria and pricing
  • Current market interest rates at the time of your application
  • Property appraisal value and location
  • State and local tax rates, which change periodically
  • Insurance costs specific to your property and coverage level
  • Private mortgage insurance rates, which vary by insurer and risk profile
  • Fees, points, and closing costs specific to your transaction

Interest Rates

Interest rates shown in our calculators are user-entered or illustrative defaults. They do not represent current market rates, rate quotes, or rates available to you. Actual rates depend on your creditworthiness, loan type, loan amount, property type, and lender. Rates change daily.

Program Rules and Regulations

Our calculators reference federal loan program rules (FHA, VA, USDA) and lending guidelines as of the date they were last updated. These rules change periodically. We make reasonable efforts to keep our tools current, but we do not guarantee that all program details reflect the latest regulations. Always verify current program requirements with your lender or the relevant government agency.

No Endorsement

NestMath does not endorse, recommend, or promote any specific lender, loan product, financial service, or investment strategy. References to loan types (conventional, FHA, VA, USDA) are for educational comparison only.

Privacy

All calculations run entirely in your browser. We do not collect, store, or transmit any financial data you enter into our calculators. For full details, see our Privacy Policy.

Intellectual Property

All content on NestMath — including text, calculators, code, design, and graphics — is owned by NestMath and protected by applicable copyright and intellectual property laws. You may use our calculators for personal, non-commercial purposes. You may not reproduce, distribute, or create derivative works from our content without written permission.

Third-Party Links

NestMath may contain links to third-party websites for reference or additional information. We do not control, endorse, or assume responsibility for the content or practices of any third-party sites.

Limitation of Liability

To the fullest extent permitted by law, NestMath and its owners shall not be liable for any direct, indirect, incidental, consequential, or special damages arising from your use of (or inability to use) our calculators or content. This includes, without limitation, damages from inaccurate calculations, financial losses, or decisions made in reliance on our tools. You use this site and its tools entirely at your own risk.

Changes to These Terms

We may update these terms from time to time. Changes will be posted on this page with an updated revision date. Your continued use of NestMath after changes are posted constitutes acceptance of the revised terms.
