Estimates, not advice

Everything on this site — every calculator result, every worked example, every guide — is an estimate for planning only. It is not financial advice, not a loan offer, and not a promise of any rate, payment or approval. We are not a bank, not a lender, not a mortgage broker, and not a financial adviser.

How the numbers are made

The calculators use the standard amortization formula and the numbers you type in. The worked examples use rates such as 6.5% as examples only — they are not live market rates, not quotes, and not predictions. Property tax rates, insurance costs, PMI rates, home value growth and rent increases in the examples are also examples. Your real figures will be different, and they are the ones that matter.

Check before you act

Before you buy a home, refinance, or pay extra on a loan, check the numbers with a lender and, where it helps, a financial adviser. Bring the breakdown from this site with you — it shows the working, so a lender can see what you assumed and correct it. Do not make a loan decision on the basis of this site alone.

Accuracy

We work to keep the formula and the examples right, and we fix mistakes when readers report them. But we do not promise that every number on the site is free of error, and we are not liable for any loss that comes from using the site or acting on its results. See the Terms of Use for more.

Contact

If you think a figure on this site is wrong, tell us on the Contact page — include the page, the numbers you typed in, and the result you saw — and we will check it.

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.
