Calculate loan payments and total interest.

How Loan Payments Work

Monthly payments are calculated using the formula:

M = P × [r(1+r)^n] / [(1+r)^n-1]

  • M = Monthly payment
  • P = Principal (loan amount)
  • r = Monthly interest rate
  • n = Number of payments

FAQ

Principal is the original loan amount you borrow, before interest.

Make extra payments toward principal, pay bi-weekly instead of monthly, or refinance to a lower rate.
