Terms of Use

These terms cover your use of Mortgage Calculators. The short version: the calculators are free estimates, not financial advice, and you use them at your own risk.

Effective date: 2026-11-09. Last updated: 2026-11-09.

Accepting these terms

By using this site, you accept these terms. If you do not accept them, please do not use the site. We may change these terms from time to time; the version on this page is the one in force when you use the site, and the "Last updated" date above shows when it last changed.

What this site is for

This site offers free mortgage, affordability, refinance, amortization, extra payment, rent vs buy, down payment and PMI calculators, plus short guides, for people in the United States. You may use the calculators for your own personal planning. You may not use the site to mislead others, to break the law, or to copy the site and present it as your own.

Estimates only

Every result on this site is an estimate. The calculators use the standard amortization formula and the numbers you type in. Rates in the worked examples are examples only, not live market rates and not loan offers. A lender's real quote depends on your credit, income, debts, the home and the lender, and it will differ from the numbers here. Nothing on this site is financial advice, and nothing here is a promise that you will be approved for a loan or offered a particular rate. See the Disclaimer for more.

Your use of the calculators

You are responsible for the numbers you type in and for checking the results before you act on them. Do not type in your Social Security number, bank account details, or any other sensitive personal information — the calculators do not need them, and the contact form asks you not to send them either.

Our content

The words, layout and code on this site belong to us, except where a source is named. You may link to any page and quote short parts of it with credit. You may not copy whole pages, re-publish the site under another name, or use the site's name or logo to suggest we back your product or service.

Links and third parties

The contact form is handled by a third-party form service, which delivers your message to our inbox. We are not responsible for that service's own terms or privacy practices. If we add links to other sites in future, we are not responsible for what those sites do.

Availability

We aim to keep the site up and the calculators working, but we do not promise it will never be down or free of mistakes. We may change, suspend or remove any page at any time without notice.

Liability

To the fullest extent the law allows, we are not liable for any loss or damage that comes from using this site or acting on its results — including a loan decision made on the basis of an estimate. If you need an exact answer, talk to a lender or a financial adviser.

Governing law

These terms are governed by the laws of the United States. Any dispute about the site will be handled under those laws.

Sources and method. Standard amortization formula: monthly rate r = annual rate / 12, n = years × 12, payment M = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1). PMI usually ends when the loan balance reaches 80% of the home value (Consumer Financial Protection Bureau guidance). Affordability uses the 28/36 rule of thumb used by many lenders. Rates in examples are examples only, not live market rates. Results are estimates, not financial advice.

Estimate, not financial advice. This calculator uses the standard amortization formula and the numbers you type in. It is not a loan offer and not financial advice. A lender will check your credit, income and debts and quote its own rate and fees before you borrow.
