Understanding Your Payment

Your $500,000 mortgage payment is calculated using the standard amortization formula. At 7% interest over 30 years, you'll make 361 monthly payments of $3,326.51.

Payment breakdown: Each month, your payment is divided between principal (reducing your balance) and interest (the cost of borrowing). Initially, 87.7% goes to interest. Over time, more goes toward principal as your balance decreases.

Rate sensitivity: At 7%, your first-month interest charge is $2,916.67. Even small rate changes significantly impact your total interest paid — see the rate comparison below.
