What Is A Car Loan Calculator? How Does It Work?

A car loan may seem intimidating at first because of all the variables. But calculators make it pretty simple. Car loan calculators take the price of the new car, your down payment, interest rate, your trade-in value, the term, and other details to give you an estimate on what your monthly payment will be. The monthly payment is generally the point of a car loan calculator. You are plugging in all the numbers to see if you will be able to afford the car's monthly payments.

Are Car Payment Calculators Accurate?

In simple terms: it depends. A lot of car loan calculators can be as accurate as you make them. In other words, the more accurate the information you put in, the more accurate the information you get out. Watch out for calculators tare too simple. If it only shows 3 or 4 variables, chances are you will get a more broad, estimated payment. However, if the calculator is able to take into consideration an accurate APR, the sales tax, and other smaller variables such as the title and license fee, then it will be reasonably close to what you will see at the dealership.

How Much Should I Put Down As A Down Payment On A Car?

Down payments are always a good idea. You should put down as much as you can afford to. The more you put down on a car, the less you will pay in interest when the car is finally paid off. This works the same way when you take a loan for a house. Generally, it is common to try and put down 20% when you purchase a home. It might be easy to assume the same for a car, but that is not necessarily the case. Making this distinction is important because a vehicle is a depreciating asset.

That's why putting down as much as you can, in the beginning, will save you money in the long run. The more you put down, the less you will pay in interest for your depreciating asset. You might as well save as much money as you can by putting down as much as you can afford.

What Is The Interest Rate On A Car Loan?

Interest rates (APR, annual percentage rate) on car loans vary. If your credit score is excellent, you're going to get a better interest rate than someone who has a bad credit score. Rates also fluctuate in the market. In January of 2015, the average rate was around 4%. In December of 2018, it was at almost 5%.

Just because you have a great credit score does not mean you will get the rate your friend got last year with the same credit score. A one or even two percent difference probably won't stop anyone from buying a car if they need or want one bad enough, so just do your research and make sure you can afford what the current APR is at. Plenty of the car loan calculators mentioned above can help figure this out.


Car loan calculators can be valuable tools in determining what kind of car you can afford to buy. Don't let the dealerships intimidate you with all the numbers and rates. With a couple of clicks from this article and an auto loan calculator, you can access all the information you need to make an educated purchase and drive off the lot in a vehicle that makes you and your wallet smile.
