What is an Interest Rate?

For you to learn how to calculate auto loan interest correctly, you first need to know what affects your interest rate. When you take out a loan on a new car, your lender will charge interest on the principal amount. So your monthly payments reflect the principal amount plus the interest charged each month for using the lender’s money to purchase your vehicle. How to calculate interest on a car loan is fairly straightforward, but you first have to consider some things:

  • Principal Amount: The principal amount is the amount you spent on the car, without interest. 
  • Loan Term: The loan term is how long the lender has given you to pay off the loan. Longer loan terms mean lower monthly payments, but that also means that you’ll have to pay more interest. 
  • Repayment Schedule:  most car payments are made monthly, but you can also pay more than the monthly payment specified in your contract. Doing so will result in less interest. 
  • Repayment Amount: When you send in your car payment each month, a portion of that amount goes toward interest in the other portion goes toward the principal amount.

How to Figure Interest on a Car Loan During Loan Term
