About Mortgage Types

Fixed-rate mortgages have constant interest rates. Variable rates can change with market conditions. Interest-only payments cover only interest initially, with principal paid later.

Mortgage Payment Formula

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

Where M is the monthly payment, P is the principal loan amount, i is the monthly interest rate, and n is the number of payments (loan term in months).
