What it does

A free loan calculator that computes your monthly payment, total paid over the life of the loan, and total interest cost. Enter principal, APR, and term (years); everything updates live. Uses the standard amortization formula — same as any bank calculator.

Before signing any loan agreement, know the full cost. A $20,000 loan at 7% for 5 years costs $3,761 in interest; the same loan stretched to 7 years costs $5,371. Longer terms = lower monthly payment and more total interest. Our debt payoff guide explains strategies to minimize this.

How to use it

  1. Enter the loan principal (amount borrowed).
  2. Enter the annual interest rate (APR).
  3. Enter the loan term in years.
  4. Read your monthly payment, total cost, and total interest.
