What is an Interest Rate?

When you’re learning how to calculate the auto loan interest rate, you first need to know what an interest rate is and the factors impacting it. Buying a car in Seattle on credit means your lender owns the vehicle until it’s paid off. The interest rate is the fee you’re paying the lender for using their money to purchase your luxury BMW vehicle. There are factors to consider before a lender decides on your interest rate:

• Principal Amount: The principal amount is the dollar amount you need to borrow. 
• Loan Term: This is the amount of time needed to repay the loan. Shorter loan terms often mean higher repayments but less interest paid in the long run. With longer loan terms, you’ll have lower monthly payments but pay more in the long run. 
• Repayment Schedule: Most car payments get paid monthly, but if you can make more payments, you will save money over time. With compounding, you make more payments and 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 the First Payment

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

This is what you will pay in interest for the first month. 

How to Figure Interest on a Car Loan Going Forward

Once you’ve started your initial payment, it’s time to calculate your new balance to figure out the interest rate you’ll pay in the following months. To get this number, you can do the following:

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

Keep in mind that human error and number rounding may not get you an exact calculation each time, but you’ll get a good idea about how to calculate the interest rate on a car loan.
