How it works
For a fixed-rate loan repaid in equal monthly installments, the payment is M = P·r / (1 − (1 + r)−n) with r = annual rate ÷ 12 and n = number of months. Lengthening the loan lowers the monthly payment but increases the total interest — compare durations to find the balance that suits you. An optional extra monthly payment shows how much interest you'd save.
