FAQ

How is the monthly mortgage payment calculated?
Payment = P·r·(1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of months (years × 12).
What is mortgage amortization?
Amortization is the process of paying off a loan with fixed payments over time. Early payments go mostly to interest, while later payments go mostly to principal.
How much total interest will I pay?
Total interest is the total of all payments over the full term minus the original loan amount — the lifetime cost of borrowing.
