Frequently asked questions
Are the calculators free?
Yes. Every calculator is free to use and needs no account or sign-up.
Is my information saved or shared?
No. The numbers you enter are processed in your browser and are not sent to or stored on our servers. See the privacy policy for details about advertising and affiliate cookies.
How accurate are the results?
They are estimates based on standard or simplified formulas and the values you enter. Real loans, taxes and prices include fees and rules that these calculators do not model, so use them for planning rather than as a final quote.
Can I rely on the results for financial, tax or legal decisions?
No. The calculators are educational tools and not financial, tax, legal or real estate advice. Talk to a licensed professional before making a major decision.
Why does my lender show a different payment?
Lenders include items such as taxes, insurance, fees and exact rate terms, and may round or compute interest slightly differently. Use your lender’s official figures for the real payment.
How do I use a calculator?
Enter your numbers in the fields, press the Calculate button and read the result. Each calculator has a guide page with a worked example you can follow.
Do the calculators work on my phone?
Yes. The site is built for phones, tablets and computers.
Does the site use cookies?
The calculators themselves do not need cookies. If advertising is shown, advertising partners may use cookies, and where required by law ads that use cookies load only after you accept. See the privacy policy.
