What is an Auto Loan Interest Rate? 

When Gardendale drivers apply for an auto loan, they’ll pay both the original loan amount and interest on the loan. Auto loan interest represents profit for car dealerships as they are distributing car loans. You can think of interest as the dealership’s fee for loaning you money to purchase your next vehicle. As you learn how to calculate interest on a car loan, you’ll want to understand the following concepts: 

  • Principal Amount: This amount represents the amount of the loan you are initially applying to borrow from a lender.
  • Loan Term: This is the amount of time given to pay off a loan. Smaller monthly payments and more interest mark long loan terms. Shorter loan terms have bigger monthly payments and less interest. 
  • Repayment Amount: This is the final amount you pay (the original principal amount plus the interest accumulated) on a loan. 

How to Calculate Auto Loan Interest on Your Initial Payment

As you’re learning how to calculate your auto loan interest for your first payment near Hoover, you can use this simple formula in advance to learn how much you can expect to repay: 

  1. Your interest rate should be divided by the number of monthly payments in the year that year.
  2. Multiply your loan balance by that figure. That amount will be your complete principal amount for your initial payment.

How to Figure Interest on a Future Car Loan

Now that you’ve learned how to figure interest on a future car loan let’s explore how to calculate auto loan interest for your remaining payments. 

  1. Subtract interest calculated from the payment already made. This will give you the principal you have thus far paid off on your loan.
  2. Subtract that total from your initial principal.
