How mortgage interest is calculated
Understanding the formula behind the payment makes it far easier to compare offers. Below are the questions borrowers ask most, plus practical tips for picking a loan.
Lenders use an amortization formula, not simple interest. Your annual rate is divided by 12 to get a monthly rate r, and the payment is P x r / (1 - (1 + r)^-n), where P is the amount borrowed and n is the number of monthly payments. Each month, interest is charged only on the remaining balance, so early payments are mostly interest and later payments are mostly principal.
