About Loan Calculator

Calculate monthly payments, interest, and total cost of loans.

Loan Calculator is a free tool in the Math & Finance category on Filepad. It runs entirely in your browser: what you give it is processed on your own device and is never uploaded to a server, there's no registration, no ads and no watermarks, and it keeps working with no connection once the page has loaded.

Practical examples
  • Work out the monthly payment on a mortgage before talking to a bank.
  • Compare total interest paid across two different loan terms.
  • See how much a slightly larger deposit changes the repayment.
