How Much Should I Spend on a Car?

If you’re thinking of buying a car, you are probably wondering how to budget for it. Figuring out how much to spend can be a challenge: Do you go for a cheaper used car or splash out on a fully loaded new vehicle? And how do you balance a car loan with other debt you may have?

Read on for guidelines to determine a car-buying budget so you can make the best decision for your needs. You’ll learn valuable options as well as helpful tips for when you are ready to start shopping.

Determining How Much to Spend on a Car

There are a few guidelines to consider when you’re trying to figure out how much money you should spend on a car. Before you dig into the details, perhaps start by taking a minute to balance your budget so you have an accurate idea of how much money you’re able to spend on a car.

Tally up your monthly income and all of your monthly expenses so you have a keen understanding of where you are spending your money. Once you have a solid grasp on your monthly expenses, you may be better able to determine how much to spend on a car.

Here are some common recommendations for determining how much to spend on a car. Think of these more as guidelines than hard and fast rules. They may give you an idea of how much you should spend on a car, but of course it all depends on your specific circumstances.

The 10% Rule

The 10% rule is pretty straightforward. The general idea is to not spend more than 10% of your gross annual income on a car. But the low limit can make it difficult to stick to this rule. If you just need a car that will get you from point A to point B, you may be able to find a vehicle that will fall under 10% of your income. But if you need a car with more features or more space, you may want to consider one of the following rules.

The 36% Rule

This rule takes into consideration your total debt-to-income ratio. This guideline suggests you keep all of your debt, including your car payments, to less than 36% of your income. If you, like many Americans, have debt from credit cards, student loans, or a mortgage, you may want to calculate how a car payment would factor in.

•   Another related guideline is the 15% rule, which can be useful if the only debt you have is a mortgage. If that’s the case, the guideline suggests that you don’t spend more than 15% of your net monthly take-home pay on car expenses.

💡 Quick Tip: Most savings accounts only earn a fraction of a percentage in interest. Not at SoFi. Our high-yield savings account can help you make meaningful progress towards your financial goals.

The 20/4/10 Rule

This is a multi-part rule.

•   First, it suggests that when you buy a car, you make a down payment of 20%.

•   Secondly, it recommends that when you take out a loan to finance the car, you plan to pay it off in no more than four years.

•   Finally, the total monthly vehicle expenses shouldn’t be more than 10% of your monthly income. Having your dream car is great, but it may not be worth it if you can’t afford to save for retirement or focus on other goals because your disposable income is primarily going toward your car payments.

The 50/30/20 Rule

If you find the above rules unrealistic, you could also consider using the general 50/30/20 budget rule. This rule says that you should spend 50% of your income on needs, 30% of your income on wants, and 20% of your income should go toward saving.

Your auto loan would fall into the needs category, but if you opt for a more expensive vehicle, you could consider a portion of the payment as part of your wants. This way, you can get the car you need with the features you want, while still keeping your budget balanced by allocating some of your discretionary spending money to your car payment.

Finding a Car You Can Afford

Buying a car can be an intimidating process. Thankfully, there are plenty of options, so you can find a car that works for your lifestyle and budget. Here are some things to consider as you embark on your search for a car that fits into your budget technique.

What Are You Going to Use the Car for?

Will you use the car mostly for quick trips to and from work? Do you have a large family that you’ll be driving to and from baseball games, soccer practices, and play dates? How you plan to use the car may influence the type of car you choose to get.

It’s also worth considering the weather. Do you live in an area with harsh winters where a larger vehicle with all-wheel drive may be helpful? There are a wide variety of vehicles on the market that fill different needs so take the time to determine which features are most important to you.

Doing Your Research

Once you decide on the type of car you want to buy, you’ll want to dig into the research phase of the process, so you are familiar with the models available, the features, and their average price.

When you’ve decided on a few models, there are a variety of resources that can help you track down details on each car. Sites like Edmunds, Kelley Blue Book, and Consumer Reports have reliable information to help consumers. And hopefully being an informed shopper will take some of the intimidation out of buying a car.

Will You Buy Used or New?

You’ll also need to decide if you plan to buy a new or used car new. If you are on a tight budget, a used car may be a more affordable option. Something to remember is that a car is a depreciating asset — it typically loses around 20% of its value within the first year.

Test Driving a Few Options

Before you consider buying, consider test driving a few options. Buying a car is a big purchase, so take your time if you’re able to. It can be worth trying the car out on a few different types of roads so you can see how it drives in different settings.

It can be easy to feel pressure to make a purchase after a test-drive, but it is a standard part of the car buying process. The salesperson will likely be interested in making the sale, but there’s no reason you need to decide on the car immediately after the test-drive. One option is to let the salesperson know at the beginning of the drive that you’re still researching options and don’t plan to buy during this visit.

Being Prepared to Walk Away

When buying a car, you may have to negotiate. Haggling can be an acquired skill, but if you’ve done the research and know exactly how much the car is worth, you can dust off your negotiating skills and try using them to work out a deal you’d be happy to accept. If negotiations aren’t going well, being prepared to walk away may help.

Saving For Your New Car

As you are saving for the purchase, consider which kind of bank account can help you get to your goal ASAP.

SoFi members with direct deposit activity can earn 4.20% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.

As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.20% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.

Interest rates are variable and subject to change at any time. These rates are current as of 10/31/2024. There is no minimum balance requirement. Additional information can be found at https://www.sofi.com/legal/banking-rate-sheet.
