The $1500 Rule For Car Buying

car buying

Is there a financial decision that people agonize over more than buying a vehicle?

A house is undoubtedly a bigger purchase, but it isn’t one that comes along as often, at least not for most people.

I often find myself in conversations with friends and colleagues who are trying to figure out how buy a car without it breaking their budget. Most fail miserably.

There are so many decisions to make.

New or used?

How much should they spend?

How will it be financed, through their bank, or through a dealership?

If it’s a used vehicle, how old is too old?

And so on, and so on.

With so much to consider, it can easily become a case of paralysis by analysis.

And for good reason.

Transportation costs make up one of the “big 3 expenses” for most families, along with housing, and groceries. And let’s face it, no matter how little you spend, a car will almost always feel like a money pit.

Such a complicated problem requires a simple solution.

A number of years ago, I came up with an easy-to-follow rule, one that takes a lot of the guesswork out of deciding how much to spend on a vehicle.

Following this rule when you buy a car will ensure that transportation expenses don’t swallow up your paycheque. The best thing is that the rule works for families across most income levels.

I call it the $1500 rule for car buying.

Before I delve into the experience that led me to the $1500 rule, here’s how it works, in all its simplicity.

The $1500 Rule For Car Buying


The rule is this: The purchase price of a vehicle (taxes included), shouldn’t exceed $1500 per year, when averaged over the number of years you own the vehicle.

The rule applies regardless of vehicle type (car, truck, SUV), or whether it’s new or used.

Note: It doesn’t account for operating costs such as fuel, or maintenance, due to their variable nature, understanding that operating costs should always be considered when shopping for a car. Remember, we’re keeping this simple. 

Here’s an example:

Let’s say you buy a used car for $12,000. Using the $1500 rule, your goal would be to own the car for at least 8 years.

Fig. 1  $12,000/8 years = $1500 cost per year.

Pretty simple, heh.

Now, if you change your mind, and decide to sell the car after only 5 years, you can do so and stay within the $1500 rule.

In this case, you would need to sell the car for at least $4500, to maintain your average annual price of $1500.

Fig. 2  $12,000 – $4500 (sale price after 3 years)  = $7500 / 5 years = $1500

Mission accomplished.

How I Came Up With The $1500 Rule

Like so many great ideas, the $1500 rule was the result of miserable failure.

The year was 2008, and my wife and I decided it was finally time to buy a minivan.

You know what I’m talking about, that moment every parent with more than 2 kids experiences.  It’s the “I give up, I surrender, I will never be cool again, it’s time to buy a minivan.”

We die a little bit inside, until we realize it’s the greatest thing ever invented.

We were those parents.

We had a young family, and the novelty of cramming three car seats into a Toyota Corolla was beginning to wear off, big time.

Unfortunately, rather than staying within our means and buying a used van, I financed a brand new, $36,000 Toyota Sienna. To this day, it was the nicest vehicle I’ve ever owned, but it was way out of our budget.

For four long years, I felt completely weighed down by the $450 monthly payment.

I came to the point where I realized something needed to give. But was it too late to correct a poor financial decision? I felt like the damage had already been done.

One day, the van went into the shop for some routine maintenance. I think it was brake pads and an oil change, something like that.

I was on my way to work, so I took a shuttle from the car dealership over to my office.

The “shuttle” was an older model Toyota Sienna, the same vehicle we owned. As we were driving, I noticed how quiet and smooth it ran. I knew it was 8 or 9 years old, but it felt just as solid as my much newer, more expensive model.

I was very surprised. I actually leaned over to check the odometer. I was shocked to see that the “shuttle” van had over 300,000 miles on it.

I made a comment to the driver about the van’s mileage, and how nicely it drove. He agreed, and said that the mileage was, in fact, one of the reasons they used it as a shuttle. To the car dealer, it was the best kind of advertising you could ask for.

This got me thinking.

Why was I driving around in such an expensive vehicle, if I could replace it for a fraction of the cost, with something that could deliver the same amount of versatility and almost as much comfort, and still last for several years.

So I started doing the math.

Because I had put a $10,000 downpayment on the van when we purchased it, we had about $11,000 of equity built in.

I realized that I could sell the van, get rid of our enormous loan payment, and still have more than enough funds remaining to buy an older model, one that could last us for several years.

I talked about it with my wife, and we decided to sell the van. Even though the numbers made sense, it was’t an easy decision.

We sold it for $21,000. This left us with $11,000 cash after the loan was paid off.

I found an 8-year old Sienna with 125,000 miles on it, and negotiated the $8500 sticker price down to $6700. Taxes in, it came to $7500.

The remaining $3500 went towards some other debt.

This is where I came up with the $1500 rule.  

At the time, my goal was for our new (used) van to last at least 5 years.

Fig. 3  $7500 / 5 years = $1500 cost per year.

In my mind, an average annual cost of $1500 was reasonable, much more so than putting down a huge downpayment and still forking over $450/mth.

Being able to pay with cash, and avoiding the monthly payment altogether made it even better.

Seven Years And Counting

Today, we’ve had our 2005 Toyota Sienna for over seven years, and it’s now at 200,000 miles and counting. It’s shuttled our family of five on numerous cross-country road trips, and has required only routine maintenance.

In fact, we’ve followed the $1500 rule and then some:

Fig. 4  $7500 / 7 years = $1,071 cost per year.

I’ll never get back the thousands I wasted buying a brand vehicle I couldn’t afford. But by being willing to correct a money mistake, my wife and I immediately improved our financial situation.

Why the $1500 Rule Works

Wondering how I decided on the figure of $1500? Here are a few reasons:

It works with a broad range of incomes. Car ownership is not a practical choice, or an economic reality for everyone. I get that. By using the $1500 rule however, you don’t need to earn $80,000/year to make it fit into the budget.

There are other factors to consider, but in a world where the average car payment is $500/month, anyone applying the $1500 rule for car buying will look pretty money savvy, regardless of income.

It favours used vehicles over new. In other words, it encourages people to spend less. Paying $45,000+ for a pickup truck or luxury SUV is a bad financial decision. Sorry, but it’s a fact. There’s simply far too much depreciation during the first 2-3 years after a new vehicle drives off the lot.

Been there, done that.

Unless you plan on owning said truck or SUV for over 30 years, it won’t meet the criteria for the $1500 rule. In other words, abiding by the rule can help ‘steer you away’ from making a big money mistake…pun absolutely intended.

It’s allows for flexibility with the purchase price (to a point). The longer you own your car, the easier it will be to get the average annual price down to the $1500 level. Keep in mind however, the more you spend, the longer you’ll need the car to last.

The $1500 Rule Sweet Spot

Price wise, I feel like the sweet spot is $7500-$10,000.

In this price range, it’s easy to find well maintained vehicles of all types, makes & models, that you can expect to have last for several years without high incurring maintenance costs.

And don’t let the number of miles on a used car scare you. If it’s a reputable brand, such as a Toyota or Subaru, a car with over 125,000 miles has plenty of life left in it.

But use caution. Before buying, always have a car inspected by a mechanic you trust, to make sure there are no surprises waiting for you. It’s worth the time, and the 100 bucks it will cost you.

Can the $1500 Rule Work for New Cars?

The short answer would be that yes, it is possible, in fact, I was successful in doing this with a car I bought new, long before I came up with the rule.

Realistically however, the instances where this would work are very limited. You really would need to buy a vehicle for less than $20,000, taxes in.

In other words, you can forget that $45,000+ F-150 or Toyota 4-Runner.

With new cars, your options are limited to base model compact or subcompact cars, such as a Toyota Corolla, or a Honda Fit. Both great cars, by the way.

You would then need to own the car for 10+ years, and also realize some resale value when you sell it.

For example, if you purchased a car for $20,000, taxes in, drove it for 11 years, and were somehow able to sell it for $4000 at the end of that time, your cost per year would be $1454.00.

Alternatively, if you drove it into the ground, and couldn’t sell it for any value whatsoever, you would need to own it for 13 years, just to get under the $1500 limit.

The $1500 Rule For Car Buying: Things To Consider

Be realistic about how long the car you’re buying will last.

Last year, my son bought his first car, and old Mazda. He paid $1800. As you can imagine, it is transportation at its most basic. That’s ok, because neither of us had an expectation of the car lasting  for 5 years.

Applying the $1500 rule, my son only needs it to last about 15 months. Anything beyond that is bonus time.

He just passed the one year mark, and it’s still running smoothly, so here’s hoping.

The make & model matters.

In this day and age, cars are more well built than ever. Still, some brands are consistently more reliable than others.

If you’re buying a used vehicle, you should favour brands known for their reliability.

This will improve your odds of owning the car for a number of years, and successfully applying the $1500 rule. Hopefully, it will also keep your maintenance costs down.

I’m partial to Toyota, as they recieve top marks for reliability throughout their product lineup, but there are other solid brands out there.

Another Rule For Car Buying

I’ve heard plenty of opinions on car buying over the years; some good, some terrible.

Another rule that I think is very sound, is that you should spend no more than 1/10th of your gross annual income on a car purchase.

In other words, if you earned $75,000/year, the most you should spend on a vehicle would be $7500.

By the same token, someone with a salary of $30,000 would limit their car purchase to $3000.

While that sounds like a paltry sum, when you factor in all of the operating costs of owning a car (insurance, fuel, maintenance), it makes a lot of sense for someone on a lower income.

Similar to my $1500 Rule, the 1/10th Rule helps to ensure that a person’s transportation costs remain low relative to your overall income.

I’d love to know your thoughts on The $1500 Rule Of Car Buying.

  1. That $1500 rule is pretty awesome. We own two “purchased new” vehicles that are now 12 and 16 years old that pass that test

      I like how you put that, it “passed the test”! 🙂 The fact that you bought two new vehicles that fit within this model is evidence of the flexibility of this rule. To me, it’s an easy way to simplify what can be an agonizing, and difficult financial decision. It definitely helps to steer people towards making smarter choices. Thanks for reading!

  2. I really like your $1500 rule! I’m not sure how many of our past vehicles would have passed this test (I’m guessing probably half or less). Buying cars seems to be one of my weaknesses… I’ll have to use that the next time we’re looking at purchasing a vehicle. Thanks for the great post!

      Hey Alan! Buying cars has been a weakness of mine as well, in fact, I think it’s probably one of the reasons I came up with this rule, as a way of keeping myself in check.

  3. I just ran across your website today. Love it! Thanks for putting together such a good website with sound financial advice.

    I love this “rule” because it is so simple. I’m in college and driving a 2001 Buick I got for free from my grandma who didn’t need it anymore. My parents’ cars are a 2001 Chevy Suburban (purchased new, now with 227,000 miles and going strong), a 2004 Sienna (purchased new, had 186,000 when it was totaled recently). So sad, because it still had a lot of life left! Siennas are awesome, and super practical. The Sienna’s replacement (which we just purchased from a friend of a friend), is a 2011 Avalon. The Avalon was a great deal at $12,000 and only 25,000 miles. Based on the Avalon’s past reliability, we should get 10+ years out of it since we only drive it 7,000 miles per year. I’ve heard of Avalons going to 300k to 500k miles!

    The Suburban hasn’t passed the test yet, but in a couple years it will. When you factor in the money we got back from insurance, the Sienna just barely passed the test. But like I said, it would’ve gone a lot more. The Buick obviously passed! And the Avalon should too. Only time will tell.

      Kyle, thanks so much for stopping by, and for the great comment. Breaks my heart to hear about that Sienna! Seriously though, I hope everyone was ok. I’ve actually been considering a used Avalon in the future. While I’m not in the market for a vehicle, I enjoy scrolling through the Kijiji app on my phone (Canadian Craigslist), looking for great deals. I actually found a couple of used Sienna’s for friends over the past few months, and they absolutely love them. Cheers!
