Loan Calculator

Estimate what a loan really costs. Enter the amount, annual interest rate, and term, and get the monthly payment plus totals.

How the payment is calculated

For a fixed-rate installment loan, the monthly payment uses the standard amortization formula:

M = P · r · (1+r)ⁿ / ((1+r)ⁿ − 1)

where P is the principal, r is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of months. A 0% rate simply splits the principal evenly across the term.

Amortization schedule

Open the schedule to see, for every month, how much of the payment goes to interest versus principal, and the remaining balance. Early payments are mostly interest; later payments are mostly principal — which is why paying extra early saves the most.
