Steps to Calculate Interest on Your Car Loan

• Principal Amount: This is the initial amount you borrow. It doesn’t include any interest.
• Interest Rate (Annual): This is the annual rate provided by the lender, often shown as a percentage.
• Loan Term: This refers to the duration of the loan, typically in months. There are long-term and short-term loans.
• Repayment Schedule: Most car payments are monthly, but you can also pay more per month voluntarily to reduce the total interest paid and the total time repaying the loan.
• Repayment Amount: A portion of your car loan payment goes towards interest, and a portion goes towards repaying your principal. 

How to Calculate Auto Loan Interest for a First Payment

If you’re figuring out how to calculate auto loan interest for an initial payment, you can use this calculation: 

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

Now you have the amount of interest that you’ll be paying that first month of your car loan.

How to Figure Interest on a Car Loan After a First Payment

Once you start to pay down your initial principal, you need to calculate your new balance to find the interest you’ll be paying for the remaining months. Here’s how to do that quickly and easily:

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

This acts as a good basis for how to calculate the interest rate on a car loan. You won’t have an exact calculation every time, but you’ll have a very close idea of how much you’ll be paying.
