What is an Interest Rate?

Before we can figure out how to calculate interest rates on a car loan, we first need to touch on what interest is and the factors that impact it. Are you planning on purchasing a car with credit?  Then your Kansas City, MO lender owns your vehicle until it is paid off. The interest rate you pay is a fee you pay the lender for using their money to purchase your vehicle. What interest rate you end up paying your lender is based on a variety of factors, including: 

• Repayment Amount: With every car loan payment you make, a portion goes to interest and a portion goes to repay your principal. 
• Repayment Schedule: Most drivers in the Wichita, KS make their car payments every month, but if you can make payments more often, it could save you money over time. Thanks to compounding, when you make more payments, you pay less interest. 
• Loan Term: This term means the length of time you will be repaying the loan. In general, shorter loan terms equal higher repayments, but less interest paid in the long run. With longer terms, you generally have lower monthly payments, but end up paying more in the long run. 
• Principal Amount: The principal amount is the dollar amount you are looking to borrow.

How to Calculate Auto Loan Interest for First Payment

Not sure how to figure interest on a car loan for the initial payment? You can use this basic calculation:

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

That’s how to calculate auto loan interest on your first month of payments!

How to Calculate Interest on a Car Loan Long-Term

Have you started to pay down your initial principal for your auto loan? Congratulations! However, you need to calculate your new balance to work out the interest you pay in the following months. To do this:

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