Frequently Asked Questions

How is the monthly payment worked out?

It uses the standard amortization formula: M = P times r divided by 1 minus (1 plus r) to the power of minus n, where P is the loan amount, r is the monthly rate (annual rate divided by 12) and n is the number of months. The same payment each month gradually shifts from mostly interest to mostly principal.

What does an extra payment do?

An extra amount each month is applied straight to the principal, so the balance drops faster, less interest builds up, and the loan is cleared sooner. Try it and watch the payoff date and total interest fall.

Does it work for car loans, personal loans or student loans?

Yes. Any fixed-rate loan that is paid back in equal monthly installments works the same way, so this calculator fits auto, personal, and most student loans.

Is my information sent anywhere?

No. The calculator runs entirely in your browser. Your numbers never leave your computer and it works offline once loaded.

What is an amortization schedule?

It is a month-by-month table showing how each payment splits between interest and principal and how the balance falls to zero. You can switch between an annual summary and the full monthly view, and export it as a CSV.

Can I use it for any currency?

Yes. The math is the same for any currency. Amounts show a dollar sign, but the payment and totals are correct whatever currency you use.
