How to Calculate Auto Loan Interest?

Paying for a car using a loan means receiving a lump sum of money from the lender, and then paying it back, with interest added, over a set period of time. The monthly amount you pay back depends on several factors: the amount borrowed, the number of installments and the interest rate.

Typically, car loans are calculated using simple interest, meaning the interest is charged only on the amount owed on a loan. This way it saves money to the borrower, as opposed to compound interest. Amortization is used when paying car loans, that is more interest is paid at the beginning of the term than toward the end.

Here is an example of a monthly payment calculation for a loan of $20,000, paid over a period of 48 months with an interest rate of 8%. If you calculate it using our car finance calculator you can see the monthly payment would be $488.

Alternatively, you can calculate it yourself using the below formula. The result for this calculation or any other combination of loan, interest rate, principal and number of the month will be identical if you calculate it manually or if you use our car loan calculator below.

EXPLANATION

Below is a detailed explanation of the factors that determine how much you will pay monthly, and the overall payment at the end of the term.

  1. Amount – the amount can equal, be higher or be lower than the value of the car. It will be higher than the value of the car because of the added interest if you do not pay a down payment. It can be equal or lower than the value of the car if you are making a down payment, or if you are trading in another car.
  2. Term – this is the number of months you have to pay the loan back. Usually, it ranges between 24 and 72 months.
  3. The annual percentage rate. Usually referred to as the APR, this is the effectiveinterest rate you pay on your loan.

Why is the interest rate for used car loans higher than the rates for new car loans?

It is important to note that financing for used cars carries a higher risk for the lender compared to financing new cars. This is because the risk for a breakdown is higher for used cars, which in turn affects its resale value and pay off. Additionally, used cars are typically financed by buyers who have a lower credit score and who are in a relatively riskier financial position.

How can I lower my interest rate?

You have several options to lower the financing rate as well as the number of monthly payments:

  1. Paying a down payment the day of your purchase
  2. Trade in your old car and use this payment for a down payment
  3. Choose a loan with a shorter duration
  4. Purchase a used car for a lower price
  5. Ask a relative or a friend to co-sign the loan with you, provided they have a better credit score
