Terms of Use

Last updated: May 27, 2026

By accessing or using Mortgage Calc Tools (homecalctools.com), you agree to be bound by these Terms of Use. If you do not agree with any part of these terms, please do not use our website. These terms apply to all visitors, users, and anyone who accesses the site.

Nature of the Service

Mortgage Calc Tools provides free online mortgage calculators and educational content for informational purposes only. Our calculators perform mathematical computations based on the inputs you provide and standard financial formulas, including the amortization formula for mortgage payment calculations, debt-to-income ratio formulas for affordability estimates, and break-even analysis for refinance comparisons.

Our calculators are designed to help you understand mortgage concepts and explore different scenarios. They produce estimates based on simplified models and the specific values you enter. The results are intended to be a starting point for your research, not a definitive answer about what you will pay or qualify for.

Not Financial, Mortgage, or Legal Advice

Nothing on this website constitutes financial advice, mortgage advice, real estate advice, tax advice, legal advice, or professional advice of any kind. The calculators and articles on this site are educational tools designed to help you understand mortgage-related concepts and perform basic calculations.

Our content is not a substitute for advice from a licensed mortgage professional, real estate agent, certified financial planner, tax advisor, or attorney. Mortgage rates, terms, qualification requirements, and regulations vary by lender, state, and individual circumstance. They also change frequently based on market conditions, federal policy, and other factors outside our control.

Before making any financial decisions regarding home purchases, mortgage applications, refinancing, or other real estate transactions, you should consult with qualified licensed professionals who can evaluate your specific situation, goals, and local market conditions.

Accuracy and Limitations of Calculators

We strive for mathematical accuracy in all of our calculators and regularly verify our formulas against known correct values and established financial references. However, we cannot guarantee that every computation accounts for every real-world factor that may affect your actual mortgage costs.

Our calculators use simplified models that may not account for private mortgage insurance (PMI) thresholds and rates specific to your lender, homeowners association (HOA) fees, closing cost variations by state and lender, local property tax assessment methods and rates, insurance premium variations based on location and property type, discount points and lender credits, adjustable-rate mortgage adjustment caps and indices, special loan program requirements (FHA, VA, USDA), state-specific mortgage regulations and taxes, or changes in tax law that affect mortgage interest deductions.

Calculator results should always be verified with a mortgage professional before you make financial decisions based on them. A small difference between an estimate and reality — even half a percentage point on an interest rate — can translate to tens of thousands of dollars over the life of a mortgage.

No Warranties

This website and all content, calculators, articles, and tools are provided "as is" and "as available" without warranties of any kind, whether express or implied. We specifically disclaim all implied warranties, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, completeness, and non-infringement.

We do not warrant that the website will be uninterrupted, error-free, or free of viruses or other harmful components.

This limitation of liability applies whether the alleged liability is based on contract, tort, negligence, strict liability, or any other basis, even if we have been advised of the possibility of such damage. In jurisdictions that do not allow the exclusion or limitation of incidental or consequential damages, our liability shall be limited to the fullest extent permitted by law.
