Loan Payment Calculator

The formula behind the number

This uses the standard amortizing-loan formula to estimate a fixed monthly payment from the principal, annual interest rate, and loan term — the same math behind most mortgage, auto, and personal loan payment schedules.

It also breaks out total paid and total interest over the life of the loan, so you can see how much of a long-term loan is actually interest. Pure math, not financial advice — actual loan terms and fees vary by lender.
