Understanding Your Payment

Your $20,000 auto loan payment is calculated using the standard amortization formula. At 6% interest over 5 years, you'll make 60 monthly payments of $386.66.

Payment breakdown: Each month, your payment is divided between principal (reducing your balance) and interest (the cost of borrowing). Initially, 25.9% goes to interest. Over time, more goes toward principal as your balance decreases.

Rate sensitivity: At 6%, your first-month interest charge is $100.00. Even small rate changes significantly impact your total interest paid — see the rate comparison below.
