How Do I Save for Buying a Car?

Article summary

• Determine your true budget by calculating total ownership costs like insurance and maintenance while using the 20/4/10 rule to keep expenses within your means.
• Calculate a specific savings target based on a 20% down payment for new cars or 10-15% for used vehicles, and automate monthly contributions to stay on track.
• Reach your goal faster by extending your timeline, reducing discretionary spending or using financial windfalls like tax refunds to boost your fund.

Buying a new or used car is one of the biggest purchases you’ll make, and with new vehicles averaging nearly $50,000 and used cars exceeding $26,000, careful planning matters.  

A clear savings target and a plan to hit it can help avoid overstretching your budget or taking on more financing than you need. Here’s how to save for a car.

Figure out what you can afford

The average cost of owning a car was $11,577 annually in 2025, so before setting your savings target, determine what fits your budget, including the costs beyond the monthly payment.

• The 20/4/10 rule: This common guideline suggests putting 20% down, having a loan term no longer than four years, and keeping total car costs under 10% of your monthly take-home pay.
• Factor in total car costs: Don’t forget that insurance, gas, tolls, maintenance and repairs can add to your monthly expenses.
• Consider other financial priorities: Housing, retirement savings, emergency funds and debt payments all impact how much you can realistically put toward a car.

Insurance, gas and maintenance alone can add $400 to $600 per month on top of the car payment. The average full coverage car insurance policy costs about $225 a month. A car that fits your payment budget might not fit your actual budget once you add up the full cost of ownership.

Run the numbers before shopping. An online car payment calculator can help you compare what different price points would cost monthly, and a driving costs calculator can give you an approximate amount of what specific models may cost per year.

Set a savings target

Common guidelines suggest putting 20% down for a new car and 10-15% for a used vehicle. A larger down payment means a smaller loan, lower monthly payments and less interest paid over time.

Here’s how it can look:

• New car at $50,000: A 20% down payment is $10,000. Add roughly $1,500 for taxes, title, registration and dealer fees, so your savings target is around $11,500.
• A used car at $25,000: Putting 15% down is $3,750. Add $1,000 for fees, and your target is $4,750.

If you have a car to trade in, its value reduces what you need to save. Checking current trade-in values can help you estimate what your vehicle might be worth.

If you don’t have a trade-in, your full down payment comes from savings, which is why starting early and staying consistent can make a big difference.

Build your savings plan

Once you have a target, turning your goal into a monthly plan can help you stay on track. It helps to work backward from when you need the car.

For example, say your goal is to save $4,750 for a used car. Saving over 12 months means setting aside about $396/month. Stretch it to 18 months, and it drops to around $264, while a 24-month timeline brings it just under $200.

Pick a timeline that best fits your budget, then consider automating transfers from checking to savings each payday. Keeping your car fund in a separate high-yield savings account can make it easier to track progress and harder to dip into for everyday spending.

Tips to reach your goal faster

If your monthly savings number feels like a stretch, you have options:

• Extend your timeline: Moving your timeline from 12 to 18 months lowers your monthly savings amount.
• Adjust your budget: Lowering your budget helps reduce the down payment and monthly payment.
• Look for ways to free up cash: Consider pausing subscriptions, cutting back on dining out, or redirecting savings from other short-term goals.
• Consider side gigs: Short-term gig work can help you move your goal forward and boost your savings rate.

Windfalls can also help. A tax refund or work bonus dropped into your car fund can shave months off the timeline. If you get a $1,500 tax refund, that’s nearly four months of savings at once if your goal is to set aside $400 a month.

When is the best time to buy a car?

Timing matters too. If you’re flexible about when you buy, you may have more negotiating power at certain times of the year, such as holidays or the end of a month, quarter or model year, when dealerships are trying to hit sales targets.

The goal is to stay consistent without putting yourself in a bind. Small, steady contributions add up faster than you’d expect.

Put your car savings plan into action

Saving for a car doesn’t have to be complicated. Knowing your budget, setting a target and building a simple plan can help you feel more prepared when it’s time to buy.

If you’re worried about being tempted to spend the money you’re saving for a car on other things, loud budgeting is a proven method to help people stick to their saving goals.

When you hit your target, you’ll have options. A strong down payment means better loan terms, more negotiating room and less pressure to finance more than you’re comfortable with.
