Loan Calculator

Estimate the monthly payment and total interest on a personal, auto, or student loan.

How loan payments work

Most installment loans use the same amortization as a mortgage. Each fixed payment covers the interest accrued that period plus a slice of the principal, so your balance shrinks faster over time.

Cutting the total cost

Two things reduce what a loan costs overall: a lower interest rate and a shorter term. Making extra payments toward principal shortens the loan and saves interest.
