Frequently Asked Questions
The monthly payment is calculated using the standard amortization formula: M = P * [r(1+r)^n] / [(1+r)^n - 1], where P is the loan amount, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments (term in years times 12).
You need the loan amount (in dollars), the annual interest rate (as a percentage), and the loan term (in years, between 1 and 50).
This calculator is designed for fixed-rate mortgages, but it can be used for any fixed-rate loan with equal monthly payments.
