If you're considering buying a new car, find out if a designated car loan or a personal loan is right for you.

If you’re looking for a loan to finance buying a car, you have 2 main options: a personal loan, or a designated auto or car loan. Although they are both loans, with terms and interest rates, they are very different types of financing.

Essentially, a car loan is designed only for buying a car. Usually, you’ll get a car loan from your dealership, although there are also online lenders that offer auto loans. Your auto loan is secured against the car that you buy, and will usually have fixed interest rates for a longer term.

A personal loan is available from a few different lenders; banks, credit unions, or online lenders, to name a few. You can use a personal loan for many different purposes, like paying for a vacation, financing a wedding, or carrying out home repairs, as well as for buying a car. Personal loans are much more varied since they could be secured or unsecured, have fixed or variable rates, and be long term or short term.

If you’re trying to decide whether an auto loan or a personal loan is better for buying a car, we help you to weigh up the pros and cons of each option and make an informed decision for your new car purchase.

What’s the Difference Between an Auto Loan and a Personal Loan?

Although every loan is different, there are some key differences between an auto loan and a personal loan. These are critical for your decision about which type of loan to choose.


Personal loans are far more flexible than car loans. You can use a personal loan to buy a car, repair your home, or make any other large purchase. This means that if you have a few large expenses to cover in the same period, you can use one loan to finance all of them together. Because a personal loan is more flexible, it also gives you more choice when choosing which car to buy. You can use a personal loan to pay for changes or upgrades to your new car, like a new paint job, better speakers, or fancy upholstery.

In contrast, a car loan only covers buying a car. You usually won’t be able to use it to make changes to your new car, like changing the seat covers or upgrading the tires. Some car loans only cover new cars, or cars that are below a certain age. You might also be restricted to buying only certain types of car, or not be able to use a car loan for a 4x4 or a truck.

Credit Score

Your credit rating is far more important for a personal loan than for a car loan. Because most personal loans are unsecured, you need to have good or excellent credit in order to get favorable interest rates. If you have poor credit, you may not be able to qualify for a personal loan at all.

On the other hand, car loans are secured against the value of the car that you're buying. That means that your car acts as collateral, so your credit score is less important when applying for the loan. If you have poor credit, you could still be accepted for a car loan and get good interest rates.

How Long it Takes

If you need a car in a hurry, then the amount of time it takes to get the funds through is a big issue. Personal loans can take a while to process—up to a few weeks. In contrast, you’ll generally be offered financing and agree to the terms of a car loan on the spot in a car dealership. Car loans are far quicker and more convenient.

Repayment Terms

In general, personal loans have higher interest rates than car loans. This is because they are usually unsecured. Car loans use the car as collateral, so that helps to lower your interest rates, although it also means that you won't own the title to the car until you finish paying off the loan.

It’s worth noting that you could get a secured personal loan that uses your new car as collateral, but in that case, you won't find it very different from a dedicated car loan.

Most personal loans allow you to choose between fixed or variable rates. Variable repayments tend to allow you to pay off the loan early without any penalties. This makes it a particularly good choice if you expect that you'll be able to pay off the loan before the term ends. Car loans almost always have fixed interest rates, so you can predict what your payments will be each month. However, it also means you can't pay them off early.

If you get a car loan through a dealership, you might be able to access special offers like 0% interest rates and $0 deposits, so it’s worth doing some research to see what extras you can get.


Most car loans require you to provide a deposit in order to qualify for the loan, which can be a problem if you don’t have much in your bank account. With a personal loan, you won’t need any down payment.

Which is Right for You: Personal Loan or Auto Loan?

In general, we recommend using a car loan to finance your new car. You’ll generally get lower interest rates, faster financing, and with some research, you could find excellent deals that mean you won’t need to pay a deposit. Because a new car depreciates in value so quickly, if you choose a personal loan, you’ll probably end up paying a lot more than its worth in interest payments. Additionally, a car loan is one option for customers with poor credit.

That said, there are some circumstances when a personal loan is a better choice. This includes if you can't get the money together for a down payment, if you want to make a lot of large purchases with a single loan amount, and/or you have an excellent credit score that allows you to unlock favorable rates.
