Behind housing costs, transportation costs are often one of the top expenses in most households.

Auto leasing has been popular for several decades, but many people still aren’t sure about the sensibility of leasing vs. buying a car, how the math works, and which is really the better value.

Should you lease a car?
In many cases, you can lease a car for less than the monthly payment for financing the exact same car. This is because with leasing, you never build any equity in the vehicle. Essentially, you are renting the vehicle for a predetermined number of miles per year with a promise that you’ll take good care of it and won’t let your kids spill ice cream on the seats. (After all, it’s not really your car.)

At the end of the lease – most often 2 or 3 years – you’ll have the option to buy the car. At this point, in many cases you would be able to find a comparable car for a few thousand less than the residual value on the car you leased. After the lease has expired, most people choose to lease another newer car, rather than buy the car they leased.

If you don’t drive many miles, there may be some advantages to leasing over buying, particularly if you prefer to drive something newer or if you need a late-model car for business reasons. As a bonus, for short-term or standard leases, the car is usually under warranty for the duration of the lease and maintenance costs are typically only for minor service items.

Should you buy a car?
If you’re like most people, when you buy a car, you’ll probably need to finance it rather than plunk down a lump sum in cash. Rates are relatively low, but you can still expect to pay a few thousand dollars in interest costs over the course of the loan. Longer loans have higher rates and more expensive vehicles can make the interest costs add up quickly. Still, at the end of the loan, you own the car.

Older cars usually have higher maintenance costs, but it may be less expensive to keep a car with under 150,000 miles and pay for any repairs, rather than make payments on a new car. Cars are also running reliably much longer now. The average age of cars and light trucks on the roads currently is up to 12 years, which means if you had a 5-year loan, you could be driving for 7 years (or more) without having to make a car payment.¹

So a big part of the savings in buying a car vs. leasing can occur if you keep the car for several years after it’s paid off. Cars depreciate most rapidly during the first 5 years of ownership, meaning you could take a big hit on the trade-in value during that time. Keeping the car for a bit longer puts you into a period where the car is depreciating less rapidly and you can benefit financially from not having a car payment. But if you think you might be tempted to trade the car in after 5 years (and you typically drive under 15,000 miles per year), you may want to take a closer look at leasing.

Keeping your car for 10 years
How would you like to “make” an extra $28,000 over the next 10 years? That’s enough to buy another car! All things being equal (you make the same modest down payment on a leased car as a financed car), and assuming an average auto loan rate for a $30,000 vehicle, you can save nearly $28,000 in a decade by buying and keeping your car for 10 years instead of leasing a car every 3 years. And that savings applies to each car you own.² (This calculation also assumes maintenance costs.)

Your savings will vary based on the type of car and its price of course, but buying a car and keeping it for a while after it’s paid off can “yield” handsome dividends.

Getting behind the wheel
It’s really up to your personal preference whether you buy or lease. If you like to rotate your vehicles so you can enjoy a new car every few years and not have to worry so much about maintenance, then leasing may be a better option. However, if you like the idea of not having to make a car payment for a good portion of the life of your car, then buying may be the right choice.

Either way, before you take the keys and drive off the lot, make sure to ask your dealer any questions you have, so you can fully understand all the terms and any underlying costs for your situation.
