Understanding Your Payment

Your $200,000 mortgage payment is calculated using the standard amortization formula. At 4.5% interest over 30 years, you'll make 361 monthly payments of $1,013.37.

Payment breakdown: Each month, your payment is divided between principal (reducing your balance) and interest (the cost of borrowing). Initially, 74.0% goes to interest. Over time, more goes toward principal as your balance decreases.

Rate sensitivity: At 4.5%, your first-month interest charge is $750.00. Even small rate changes significantly impact your total interest paid — see the rate comparison below.
