What Are Car Loan Interest Rates?

The first step in learning how to calculate auto loan interest is to understand exactly how car loan interest rates work. When you buy a new vehicle on credit, your lender essentially owns your vehicle until it’s fully paid off. The interest rate is a monthly fee that you pay the lender for using their money to buy your car. Your particular interest rate will vary based on four key factors:

• Principal amount: The dollar amount you’re looking to borrow.
• Loan term: The length of time you’re going to be repaying the loan. If you have a shorter loan term, you tend to pay more per month but you also have a lower interest rate.
• Repayment schedule: The timeline for when and how you’re going to make your payments—most operate on a monthly term.
• Repayment amount: When you make your monthly payment, a portion goes to the principal amount and a portion goes to interest.

How to Calculate Auto Loan Interest for First Payment

Now that you know how an interest rate works, let’s look at how to calculate the interest rate on your first payment. Just make this calculation:

1. Divide your interest rate by the number of monthly payments you will be making over the next year.
2. Multiply it by the balance of your loan, which for the first payment, will be your whole principal amount.

The resulting number will be the amount of interest you pay in the first month of owning your new Metairie vehicle.

How to Figure Interest on a Car Loan Going Forward

Once you make your first payment, you’ll need to calculate the interest you pay going forward for your loan term. Keep in mind that this is an estimate since there are always human rounding errors, but it should give you a basic idea of what to expect from your car loan interest rates. Here are the calculations to make:

1. Subtract the interest you just calculated from the last payment you made and this will leave you with the amount that you have paid off the loan principal.
2. Deduct this total from your original principal to get your new loan balance.
