The average new car costs $40,720, while the average used car costs $29,983 according to the latest iSeeCars data. While used cars are significantly cheaper than new cars , both are still a major expense. That’s why it’s important to set a realistic budget and determine how much money you can afford to pay for your new -- or new to you -- car. We have the answers to help you determine that age-old question: how much car can I afford?

1. Determine Your Credit Score

Unless you’re paying for your car in full, you’ll need to secure a car loan . The first step toward getting a car loan and figuring out how much you can afford to pay is determining your credit score . This can also be referred to as your “FICO score” and is a numerical representation of your credit history . The three major credit reporting agencies – Equifax, Experian, and TransUnion – can each provide you with your FICO credit score . Another option is to check with your bank or credit card companies. Many of these institutions also provide a free credit monitoring service that will tell you your credit score

A credit report , as well as monitoring services, also include a record of your credit history , including any items that are lowering your credit score . The higher your credit score , the better loan term you will be able to secure. Car manufacturers and dealerships will advertise special payment terms like zero-percent financing, but it’s important to remember those terms typically only apply to buyers with favorable, if not top-tier, credit scores

If your credit score is low, you should try to boost your number before you purchase a car. You should aim for a credit score of 680 or above, but higher is always better. You can start by making sure you make your credit card and loan payments -- especially any auto loan payments -- on time. Resolve any past-due accounts, and pay down as much of the balance on your loans as you can, especially revolving credit accounts. You should also avoid opening new accounts, as frequent inquiries to the credit bureaus seeking new credit can lower your credit score .

While a good credit score isn’t required to secure a car loan , it will afford you a better annual percentage rate (APR) on the interest you’ll have to pay. The higher interest rate you have, the more you will end up paying in the long run. If you are unable to achieve a favorable credit score , another option is to get a co-signer on your loan. Your co-signer will agree to make loan payments if you default on your loan, which can lower an otherwise high interest rate .

2. Determine Your Down Payment

Making a down payment will lower the amount of the loan, or principle, you will need to take out, which will reduce your monthly payment . This also reduces the overall interest you’ll pay on the loan over time. While this can help make a car easier to afford, don’t deplete your savings account. Be sure to keep enough money on hand for whatever surprises might come your way. Dealers and lenders may offer deals for zero down payment financing, but you can still put money down to shorten the length of your loan and reduce your monthly payment .

3. Estimate the Value of Your Trade-In

The process of trading in your car begins with determining how much your car is worth. Major factors that impact your car’s value include how many miles it has on the odometer and its overall condition. Having your vehicle professionally detailed can also boost the trade-in value for your current vehicle.

Several websites, including Edmunds ( Edmunds.com ) and Kelley Blue Book ( kbb.com ) have valuation tools that will give you a ballpark estimate on the value of your car. Make sure you are as honest as possible in answering any questions about your car’s condition. Some valuation tools offer an estimate specifically for trade-in value , but that’s just what it is – an estimate.

You can also sell your car to a private buyer, which will be more profitable than trading your car into a dealership . In this instance, you can price your car in accordance with its market value, which is higher than your car’s trade-in value . A car’s trade-in value is the amount of money a car dealer will offer you for your vehicle, whereas market value, also referred to as private party value, is the amount of money you would get selling your car directly to a buyer. Because dealerships handle the complex process of selling the vehicle, they offer a lower trade-in value to ensure they make a profit when they sell the car. 

There are helpful online tools like the iSeeCars Price My Car Tool , which provide a detailed pricing report to help calculate your used car ’s value. Simply enter your vehicle’s VIN or provide its make, model, year, trim, style, and mileage. 

Whether you decide to sell your car privately or trade-in at the dealership , you can apply your car’s value toward the purchase price of your next vehicle, along with your down payment if you’re making one. 

4. Calculate Your Car Budget

Setting a monthly budget will guide your new or used car search. As a general rule of thumb , your car payment should not exceed 10 percent of your monthly income , and your total car expenses (fuel, maintenance, car insurance , registration) should not exceed 15 percent of your monthly take-home pay . Or, if you’re paying in cash, determine the amount you’re willing to pay for your vehicle. You can use the 15 percent rule as a guide, but if you have other major monthly expenses like student loans, you should determine a monthly payment you can comfortably afford.

5. Determine Your Car Loan Amount

After you determine your monthly payment amount , you can determine how much you can borrow from a lender. One way to do this is by obtaining a pre-approval letter from a financial institution, which will review your credit history to determine how much money they will loan you. Keep in mind that you might be pre-approved for more than you can afford, so make sure you stick to your budget. You can also use a car affordability calculator , which is available on many personal finance websites, by entering your credit score , estimated monthly payment , and desired loan term . Remember -- the shorter your loan term , the less you will pay in interest over time. Don’t be tempted to stretch out your loan term in order to have a smaller monthly payment , because you’ll end up paying more in the long term. For example, if you purchase a $25,000 used car and put $4,000 down with an interest rate of 4.5 percent, your monthly payment on a four-year loan will be roughly $625 and you will pay $1,488 in interest over the duration of the loan. If you spread the loan out over five years with a higher interest rate of 5 percent, you will pay roughly $396 per month and nearly double, $2,778, in total interest. While a smaller monthly payment might seem appealing, it will cost you a lot more in the long run.

It’s important to note that most lenders will not provide a loan on a vehicle that’s more than five years old, so if you are relying on the financing you should consider a later model used vehicle.

6. Shop Around fr the Best Loan Rates

??You should always visit a bank or credit union to get pre-approved for a loan before you go to the dealership . Even if you plan on securing an auto loan through the dealership , having a pre-approval option from a financial institution can help you negotiate against the dealer’s rate. It will also show them that you are a serious buyer, which will give you more bargaining power. Because dealers make more money on vehicles they finance, they will likely try to beat the rates you’ve already secured.  

7. New or Used?

When purchasing a vehicle, you have the choice of buying a new or used car . Although they are more expensive, there are perks to buying a new vehicle, including peace of mind, the reduced likelihood of unexpected repair bills, and warranty coverage. New cars also typically come with lower interest rates and financial incentives.

According to an iSeeCars study on off-lease car deals , the average used car loses 39 percent of its value after three years. When you buy a used car , the largest percentage of depreciation has already been absorbed by the original owner, and you get the car at a much lower price. You can even buy a car that is just one year old, which will typically cost 17 percent less than its new version. However, in today’s market, some lightly used cars cost more than their new versions , so be sure to compare the cost of new and lightly used vehicles. You may find that buying a new car is a better financial decision than purchasing a lightly-used one.

If you’re purchasing your used car through a franchise dealer, you will have the option to purchase a certified pre-owned (CPO) car. (Check out our handy guide to learn what does certified pre-owned mean ? to better understand the CPO car buying process.) CPO cars are typically used cars that are less than five-years-old and have fewer than 75,000 miles on the odometer. CPO cars typically cost slightly more than non-certified used cars , but they are backed by manufacturer warranties and may also carry special financing. CPO cars combine the best of both the new and used car worlds, by offering added warranty protection on a late-model used car .

8. Buying or Leasing?

Another factor to consider is whether you want to buy or lease your vehicle.  If you choose to lease, you don’t need to finance because you’re not buying the car. You just need to be able to afford the down payment and the monthly payments . If you don’t want to borrow from a bank and take out a loan, leasing could be your best option. Your lease payments typically cost less money than what you would pay for a monthly car payment if you were buying the vehicle. You can also get a much nicer car for your money and get to drive a new car every few years. Another benefit of leasing is that you don’t have to pay for repairs, as issues with your car that occur during your lease term are usually covered by the car’s factory warranty .

The downside to leasing is that you never own the vehicle. As soon as your leasing term ends, you will begin the cycle again. If you purchase a vehicle, you will likely be able to enjoy several years without a car payment , provided that you don’t take out too long of a loan term . Another drawback is that car leases come with mileage limits, which commonly range from 12,000 to 15,000 miles per year. If you exceed those mileage limits, you will have to pay excessive mileage fees, which can get expensive. Lastly, the upfront cost to lease is usually more than if you were purchasing. You might need to put down a larger down payment due to your credit score , and it’s likely that the dealership will often want the first month’s payment as well.

9. Be Sure to Factor In Extra Costs

It’s important to make sure you budget for more than the advertised price of the car . While each state has different taxes and associated fees, you can expect to pay an extra 10% on top of the purchase price to cover the total cost of the vehicle. This includes sales tax , which is typically 5 percent to 10 percent depending on your state. There’s also documentation and registration fees , which also vary by state and the amount can be found on your state’s department of motor vehicles website. If you’re financing the vehicle, it’s important to understand you’ll also be paying interest on the financed portion of the vehicle. You should also research the car’s ownership costs to get a better understanding of what you’ll be paying per month. Car insurance is a major added expense, and it will cost more on later-model used vehicles. Be sure to check with your insurance agent before you purchase the vehicle to get an idea of what your new monthly rate will be. Be aware that used car insurance rates are also higher on sports cars and performance vehicles. You can also take the opportunity to shop around with other insurance companies to ensure you’re getting the best rate. If you’re purchasing an SUV or a less fuel-efficient vehicle, you should also factor in additional fuel costs to make sure there is room in your budget. (You can refer to our list of Best Gas Mileage Cars to help reduce your fuel costs.)

10. Find the Right Car  

Once you’ve determined your budget, you can now search for cars within your budget. Helpful car websites and search engines have made it easier and more convenient than ever to find the right car to meet your needs. Car search engines like iSeeCars.com equip buyers with all the information they need to find the right vehicle. 

When deciding on a vehicle, some important things to consider include:

  • Why are you buying a car? Do you need a spacious family hauler or a fuel-efficient car for commuting?  
  • Are you looking for the safest car possible?
  • How long do you plan on keeping the car? If longevity is important to you, you should consider vehicles that have proven to be among the longest-lasting cars
  • How important is fuel efficiency to you? Should you consider a hybrid or electric vehicle to cut down on fuel costs?
  • Do you have towing needs? If so, consider a vehicle with a high towing capacity.
  • What kind of features are most important to you? Do you want the latest safety features like automatic braking and lane departure warning? Or comforts like ventilated seats or a heated steering wheel?

11. Beware of Depreciation

The depreciation on a new car means there’s a much greater loss in its value in the first few years after purchase compared to a used car . After all, The average new car loses nearly half its value after five years. If you’re going to keep your new car for the life of your loan, which will likely be between 5 and 7 years, that’s not a concern. But if you decide to switch cars earlier, the vehicle’s depreciation represents a significant ownership cost. If you plan to switch cars every few years you’ll save a lot of money buying cars that are at least 3 years old. Keep in mind that cars depreciate at different rates, so buying a car that best holds its value is a smart purchase decision.

12. Find the Best Price

Now that you’ve selected which models you’re interested in, you can do your research to find the best deal.
