Auto Loan Payment Example


A car is financed using a three-year loan. The loan has a 8% nominal annual interest rate, compounded monthly. The price of the car is 7,000, and a deposit of 2,000 is paid in cash. Calculate the monthly auto loan payments, assuming that the payments start one month after the purchase.


The value of the loan is the price of the car less the initial deposit (7,000 – 2,000 = 5,000) (PV). This loan is repaid using monthly installments, so one period is one month, and the term of the loan is 3 years or 36 months (n). The interest rate has been quoted as an annual rate so the periodic (monthly) rate is 8%/12 per month (i)

As the auto loan payments (Pmt) are made at the end of each period, and we know the present value, the problem is solved using the annuity payment formula. as follows:

Auto loan payment = PV x i / (1 - 1 / (1 + i)n)
PV = Value of the auto loan 5,000
n = number of months = 3 x 12 = 36
i = nominal rate = 8%/12 per month
Auto loan payment = 5000 x (8%/12) / (1 - 1 / (1 + 8%/12)36)
Auto loan payment =  156.68 


For the auto loan balance to be cleared at the end of 36 payments, the present value of the payments must be equal to the present value of the auto loan.

The solution to this problem simply uses the present value of an annuity formula to find the 36 payments which, at a discount rate of 8%/12, will give a present value of the auto loan of 5,000.
