How to Calculate the Interest Rate on a Car Loan

If you’re looking to finance your next ride in the Cerritos area, it’s important that you put together a budget that accurately reflects your financial situation.

A lot of drivers don’t necessarily know how to calculate auto loan interest, but the finance team at Lexus of Cerritos is here to help! We’ve put together a guide outlining everything you need to know below – check it out, and feel free to contact us with any questions.

What is an Interest Rate?

Before we get into details on how to figure interest on a car loan, let’s go over how exactly interest works. Essentially, when you finance a vehicle in Long Beach, you make a deal with a lender where they buy the vehicle and you pay them in installments until it’s paid off. In addition to the price of the vehicle, you pay a certain amount in interest each month. In short, interest is a fee that you pay the lender in exchange for them using their money to buy your vehicle. Several factors affect your interest rate:

• Principal Amount: The principal amount is the dollar amount you are looking to borrow.
• Loan Term: The length of time you will be repaying the loan. In general, shorter loan terms equal higher repayments, but less interest paid in the long run. With longer terms, you generally have lower monthly payments, but end up paying more in the long run.
• Repayment Schedule: Most car payments are done monthly, but if you can make payments more often it could save you money over time. Thanks to compounding, when you make more payments you pay less interest.
• Repayment Amount: With every car loan payment you make, a portion goes to interest and a portion goes to repay your principal.

How to Calculate Auto Loan Interest for First Payment

There are two steps to the equation for calculating interest on your first auto loan payment:

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

How to Figure Interest on a Car Loan Going Forward

The interest rate for your first payment is not necessarily the same interest rate you’ll pay going forward, so you’ll need to calculate it again. Keep in mind that these equations will give you an estimate of your interest, since human error and rounding may make the final amount a bit different.

1. Subtract the interest you just calculated from the payment you just 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.
