What is an Interest Rate?

Before spotlighting how to calculate auto loan interest, we need to discuss what interest is. For those who purchase a new Nissan on credit, your lender owns the vehicle until it’s paid off. The interest rate you pay is a fee you will pay the lender for using their money to purchase your vehicle. So, how to calculate an interest rate on a car? Well, the interest rate you end up paying your lender is based on multiple factors, including: 

• Principal Amount: Your principal amount is the dollar amount you plan to borrow.
• Loan Term: This means the length of time you will be repaying your loan. In general, shorter loan terms equal higher repayments but lower interest paid in the long run. With longer terms, you will have lower monthly payments but will pay more in the long run.
• Repayment Schedule: Most car payments are done monthly, but you can make payments more often if it saves 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

When determining how to calculator auto loan interest for your initial payment, you can use this quick calculation:

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

This gives you the amount of interest you pay the first month on your Compton commuter.

How to Figure Interest on a Car Loan Going Forward

Once you’ve begun paying down your initial principal, you’ll need to calculate your new balance to work out what interest you’ll be paying in the coming months. Curious how to figure interest on a car loan? You must do the following: 

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.

While number rounding and human error mean you won’t have an exact calculation every time, this gives you a basis on how to calculate the interest rate on a car loan.
