Formula Used

The monthly payment for an auto loan is calculated using the standard loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

This formula accounts for the interest charged on the outstanding loan balance each month, which is added to the principal amount.

Worked Example

Let's calculate a used auto loan with these details:

Loan amount: $20,000
Interest rate: 4.5% APR
Loan term: 5 years

First, convert the annual interest rate to a monthly rate:

Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375

Next, calculate the number of payments:

Number of payments = 5 years × 12 = 60 months

Now plug these values into the loan payment formula:

Monthly Payment = $20,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Monthly Payment ≈ $362.50

Over 5 years, you would pay approximately $21,750 in total, with $1,750 going to interest.

FAQ

What is the difference between APR and interest rate?

The Annual Percentage Rate (APR) is the total cost of credit, including fees and interest, expressed as a yearly rate. The interest rate is the actual percentage charged on the loan balance. APR is always higher than the interest rate because it includes additional costs.

Can I get a used auto loan with bad credit?

USAA offers loans to military members and their families, but specific credit requirements vary by loan type. Some USAA auto loans may be available with less-than-perfect credit, but you may need to pay a higher interest rate. It's best to check with USAA directly for your eligibility.

How much can I afford to borrow for a used car?

You can generally afford a loan amount up to 20-30% of your gross monthly income. For example, if you make $3,000 per month, you might qualify for a loan up to $600-$900 per month, depending on your credit score and other financial factors.
