What is an auto loan?
An auto loan (or car loan) is a type of shortterm personal loan used for purchasing a car. It works like any other secured loan granted by a financial institution. Once you take a loan, you have to make a repayment each month on the principal and the interest. The main difference between the standard shortterm loan and an auto loan is its purpose — in the case of an auto loan, it is strictly defined. Another difference is that car loans have a builtin collateral — the purchased car. So, if you cannot pay the installments and, as a consequence, cannot pay back the borrowed money, the car is legally repossessed to the lender.
Car loans differ from mortgages because you do not need any real estate collateral to apply for them. Also, the loan granting process is less complicated and shorter in the case of auto loans. Another difference is the payback period length: in the case of mortgages, it could be as long as 30 years, and the typical term of a car loan is between 12 to 60 months.
How does a car loan work?
Well, it is easier than you think. Once you find the car you want to buy, you usually know its price. Based on the calculations using that price, you should be able to work out the amount you need to borrow. In the simplest case, it is the price of the car minus the money you have.
A car loan allows you to borrow a fixed sum of money you need to buy the vehicle. After the purchase, you must repay it in fixed monthly payments, usually over one to five years (1260 months). The interest rate is typically constant over the lending period and depends on how much you borrow. The general rule of thumb says that the smaller amount you borrow, the higher the interest rate is.
When considering taking a car loan to buy a new car, it is worth knowing that there are two main types of financing on a car loan: direct lending and dealership financing.
 Direct lending is a typical loan taken from a bank or credit union. You sign a purchase contract with a car dealer and then use the money borrowed from the direct lender to make the appropriate payments.
 In dealership financing, a car dealer initiates the process of taking a loan and doing all the necessary paperwork. In dealership financing, you usually cannot choose the lending institution – usually, the loan is granted by socalled captive lenders associated with a car manufacturer.
Note that to promote sales, car manufacturers offer attractive financing opportunities via dealers. Usually, it is more profitable to buy a new car with dealership financing, as it is significantly cheaper – interest rates in such loans can be as low as 0.5%, 1%, or 1.5%.
Car loan payment formula
Our car finance calculator uses the following formula to calculate the monthly payment:
Monthly payment = (loan amount) × (interest rate / 12) / (1 − (1 + (interest rate / 12)) ^ (loan term)).
The interest rate
is given for a period of one year.
The loan amount
is the amount of money you need to borrow and is calculated as follows:
loan amount = price of the car − money you have − (tradein value × (1 + sales tax))
where:
price of the car
— the final purchasing price;money you have
— the cash you have to spend on a car;trade in value
— the value of your current car; andsales tax
— sales tax rate.
Car loan calculator – an example of calculations
Now we know the formula used in the car loan payment, we can try to perform a sample calculation.
Firstly, let's assume that you want to buy a fiveyearold Jeep Wrangler worth $20,000. You also have a car – an old Chevrolet Silverado worth about $7,000, and $1,500 in your savings account. The sales tax in your state is 10%, and the interest rate on the car loan is 4%. You want to take a threeyear loan.
To calculate the monthly payments, we need to stick to the following steps:

Estimate the amount of money you will get for your old car. It is the tradein value minus tax:
$7,000  $7,000 × 10% = $6,300

Calculate the amount of money you need to borrow. It is the value of a new car minus the money you get from selling an old car and money you can withdraw from your bank account:
$20,000 – $6,300 – $1,500 = $12,200

Use the appropriate formula to compute the monthly payments:
($12,200) × (4% / 12) / (1  (1 + (4% / 12))^(36)) = $360.19

The answer is $360.19. It is your monthly payment in the loan from our example.

If you want to know what is the total cost of your loan, multiply your monthly payment by the number of months you will pay your loan and then subtract the total amount of the loan from that value:
$360.19 × 36 – $12,200 = $766.93
You can also forget about all these long hours of counting and use our smart auto financing calculator to obtain all these values.
How to use the auto loan payment calculator?
To use our car loan calculator, start by filling in the field Price of the car. It should be the final price of the car you want to buy.
Then, provide an annual interest rate (if you don't know how to calculate annual interest, use our APY calculator).
In the simple mode, the value in the field loan amount is filled automatically – it is the same as the value in the field price of the car. However, you can provide additional information that helps determine the amount of money you need to borrow. These are money you have, tradein value, and sales tax. We have already explained their meaning in the section car loan payment formula.
In the next step, choose the payback period (loan term). It could be expressed in years and months. However, it is usually a multiple of a year.
And that is it! The result of the calculation will appear immediately in the field monthly payment. This is the amount you will have to pay every month to repay your debt.
The amount in the field total interest paid at the bottom of the auto loan calculator shows the total cost of your loan within the whole period.
Do you think that the estimated monthly installments are too high? Or maybe you believe you can afford to pay higher installments? Try to change some values in our calculator. For example, lengthening the loan term will result in lower monthly payments. Similarly, a lower interest rate leads to lower installments. However, you need to remember that the interest rate depends mainly on the lender's offer.
Pros and cons of taking an auto loan
A car loan is not the only option when buying a new car.
Probably the best solution is to buy a car outright with cash. First, it allows you to avoid monthly payments, which may be a severe burden on your budget. Moreover, paying with cash means that you do not have to pay interest, which reflects the price of borrowing, not the price of a car. Also, an outright purchase gives you full flexibility, as you can do whatever you want with the car. Last but not least, when you buy with cash, you avoid the risk of an underwater loan — the situation in which, due to the depreciation, you owe more than the car is worth. The car depreciation calculator shows how a car's value reduces with age.
Unfortunately, not everybody can afford to buy a car with cash. Sometimes, you have to decide whether to take a car loan or lease a car (check the car lease calculator to learn about the latter option). Below, you will find some pros and cons of taking a car loan.
Pros
 Auto loan is a very simple product. It is easy to arrange and understand.
 Car loan is flexible – you can choose the payback period from one to five years.
 Thanks to a car loan, you become a legal owner of the car just after the purchase. So, contrary to leasing contracts, you can immediately modify the car exactly as you desire.
 From the seller's perspective, you are a cash buyer, so you have a stronger position in price negotiations.
Cons
 If you do not have a good credit score, you will not get a car loan.
 In the case of a car loan, the monthly installments may be higher than in other forms of financing the purchase (e.g., leasing).
 Contrary to the leasing agreements, you are responsible for the service and all vehicle repairs.
 Due to the car depreciation, your car will be worth less each year. When you decide to sell it, it will be considerably cheaper than at the time of purchase.
Does a bank give you cash for an auto loan?
It depends, but usually, a bank gives money to the buyer directly. You should ask your bank for information on a specific auto loan you're interested in before purchasing a vehicle.
Can I refinance my auto loan?
Usually yes, you can refinance your auto loan if your bank approves. Refinancing means replacing your current loan with a new one, often with better terms like lower interest rates or extended repayment. It can help reduce monthly payments or save money over the life of the loan.
How do I calculate my auto loan?
To calculate your auto loan:
 Calculate the amount you need to finance your car.
 Find the annual interest rate offered by your bank on auto loans.
 Decide on the loan term (typically 15 years).
 Divide the loan amount by your loan term, multiply the result by the annual interest and multiply that by the loan term. Remember to consider any extra costs like provision for the dealer.
Can I afford a new car?
Determining whether you can afford a new car depends on your financial situation. Consider factors like your monthly income, expenses, and savings goals. A general rule is that your car payment should be around 15% of your monthly income. Ensure you can comfortably cover this expense without compromising your other financial priorities.
How much do I pay back on a $50,000 auto loan?
The amount you pay back on a $50,000 auto loan depends on:
 The interest rate; and
 The loan term.
For example, with a 5% interest rate and 36month term, you have to pay back $53,947.61.
