Understanding Your Payment

Your $100,000 loan payment is calculated using the standard amortization formula. At 5% interest over 30 years, you'll make 361 monthly payments of $536.82.

Payment breakdown: Each month, your payment is divided between principal (reducing your balance) and interest (the cost of borrowing). Initially, 77.6% goes to interest. Over time, more goes toward principal as your balance decreases.

Rate sensitivity: At 5%, your first-month interest charge is $416.67. Even small rate changes significantly impact your total interest paid — see the rate comparison below.
