The lease is cheaper every month and that's not the point

Take a $38,000 SUV. Not a fantasy car, just the mid-trim thing with three rows that your wife actually wants. The lease on it comes to about $578 a month. The 60-month loan comes to about $693 a month with three grand down. The salesman will point at those two numbers, let you do the subtraction, and wait.

Don't take the bait. Those two payments aren't buying the same thing, and the only way to know which one wins is to run both out to the end and see what you're holding.

So let's run them. Every number below is a worked example, not a quote. Plug in the ones on your own paperwork.

What the lease payment is actually made of

A lease payment has two halves, and once you see them you can never un-see them.

The first half is depreciation. The bank buys the car for $38,000 and guesses what it'll be worth in 36 months. Call the residual 58 percent, or $22,040. The difference, $15,960, is what you're renting. Divide by 36 and you get $443 a month.

The second half is the rent charge, which the industry calls the money factor. Say it's 0.00225. Multiply that by the sum of the cap cost and the residual, $60,040, and you get $135 a month in interest.

$443 plus $135 is $578. That's the payment.

Now the single most useful trick in this entire article: multiply the money factor by 2,400 to get the APR. 0.00225 × 2,400 = 5.4 percent. Dealers quote money factors precisely because nobody knows what they mean. Ask for it in writing. If they won't give it to you, you already know why.

Three years later, the lease scoreboard

$578 × 36 = $20,808. Add an acquisition fee of around $695 baked in at the start and a disposition fee of roughly $400 when you hand the keys back. Call it $21,900 in real dollars over three years.

What do you own? A photograph of the car and a receipt.

That's not an insult. Renting isn't immoral. But be honest about what you bought, which is 36 months of use and zero equity.

Three years later, the purchase scoreboard

$3,000 down, $35,000 financed at 7 percent over 60 months, payment of $693. Over 36 months you've paid $3,000 + $24,948 = $27,948.

Your loan balance at month 36 is about $15,478. The car is worth roughly what the leasing bank guessed it would be, $22,040. Subtract and you've got about $6,562 in equity sitting in your driveway.

Real cost of ownership over three years: $27,948 minus $6,562 = $21,386.

Real cost of the lease over three years: $21,900.

It's a wash. That's the part nobody tells you. At the three-year line, leasing and buying cost about the same money, and the lease costs you less per month. If you genuinely intend to be in a different car in 36 months, the lease isn't the dumb choice. It might be the smart one.

Then year four happens

Keep buying and the math stops being close.

Months 37 through 60, you pay $693 a month and then you're done. Total out the door: $3,000 + $41,580 = $44,580. You own an eight-year-old vehicle with maybe 100,000 miles.

Then you drive it five more years with no payment at all.

Across ten years and 120 months, $44,580 works out to $371 a month, plus maintenance, and you finish with a car worth something. Tires, brakes, a water pump, a set of struts. Fine. Call it real money, maybe $6,000 over the back half. You're still under $430 a month, all in.

Lease it for the same ten years and you sign three and a bit contracts at $578, rising every cycle because cars get more expensive and residuals soften. Call it $620 a month averaged, forever, with no end date and nothing to sell.

That's the whole argument. The lease isn't more expensive in year three. It's more expensive in year seven, when the guy who bought has no car payment and is putting $693 a month somewhere it compounds.

The four line items that eat lessees alive

Mileage. A 12,000-mile lease at 25 cents a mile sounds harmless until you actually drive. Do 18,000 a year and you're 18,000 miles over at lease end. That's $4,500 on a car you're handing back. Look at your current odometer, divide by the years you've owned it, and use that number. Not the one you wish were true.

Wear and tear. The inspector carries a tread gauge and a plastic card with a hole in it. Curbed wheel, windshield chip, a tear in the third-row seat where the car seat buckle lived. These are real charges.

Down payments. Never put a big down payment on a lease. If the car gets totaled in month four, gap coverage pays off the bank. It doesn't send your $4,000 back to you. Structure a lease with as little cash up front as the deal allows.

The assumption that the price is fixed. The capitalized cost on a lease is the sale price of the car, and it's every bit as negotiable as a cash deal. Negotiate the price first. Only mention the word "lease" once you've got a number in writing.

When leasing genuinely wins

I'd be lying if I said never.

If the vehicle is used in a business, the tax treatment can change the answer completely, and that's a conversation with your CPA, not with me or with the finance manager.

If you're buying something with brutal depreciation, a loaded European luxury sedan being the classic case, the leasing bank is often wrong about the residual in your favor. You're effectively getting a subsidized guess.

And if you drive under 10,000 miles a year on predictable routes and you want to be under factory warranty every single day you own a car, a lease does that cleanly. Some people want zero surprises more than they want equity. That's a legitimate preference, as long as you know the bill.

The option that beats both

Buy the car somebody else leased.

A three-year-old version of that same SUV, coming off a 36-month lease with 34,000 miles and a service history, prices around that $22,040 residual. The first owner paid $21,900 to eat the steepest depreciation in the car's life. You get the flat part of the curve.

Finance $19,000 of it over 48 months and you're at roughly $455 a month, done in four years, in a vehicle that'll run another decade if you change the fluids.

Do this before you go

Write three numbers on an index card and put it in your shirt pocket: the out-the-door price you'll accept, the money factor or APR you'll accept, and your honest annual mileage. Not one of those numbers is the monthly payment.

Every bad car deal in America starts the same way, with a man answering the question "what do you want your payment to be?" The right answer is that you don't. You want a car, and eventually you want to stop paying for it.
