About the Loan Calculator

Plan a personal loan, student loan or business loan. Enter the amount, APR and term to get the fixed monthly payment and the total interest you'll pay. The amortization schedule shows how each payment splits between principal and interest, and an optional extra monthly payment reveals how much faster you can be debt-free.

How to use it

  1. Enter loan amount, interest rate and term.
  2. Optionally add an extra monthly payment.
  3. Review the payment, totals and schedule.

Good to know

  • Results are estimates for planning purposes and not financial, tax or legal advice. Lenders and tax authorities may calculate differently.
  • Assumes a fixed rate, monthly payments and no fees. Origination fees increase the real cost (APR).

Frequently asked questions

How is the monthly payment calculated?

With the standard amortization formula M = P·r / (1 − (1 + r)^−n), where r is the monthly rate and n the number of payments.

Do extra payments save money?

Yes. Every extra dollar reduces principal immediately, cutting future interest and the number of payments.
