The lower monthly payment on a lease ad is real - but it's telling you less than half the story. Buying and leasing solve different problems, and picking the wrong one for your driving habits can cost thousands over a few years. Here's the actual math side by side.
Why Lease Payments Look So Much Cheaper
A lease payment is based only on the vehicle's projected depreciation during the lease term, not its full price. If a $38,000 car is projected to be worth $22,000 after 3 years, you're essentially financing the $16,000 difference (plus interest, called the "money factor," and fees) - not the full $38,000 a loan would require.
Side-by-Side: $38,000 Car, 3-Year Horizon
| Factor | Lease (36 mo) | Loan (60 mo, keep 3 yrs) |
|---|---|---|
| Monthly payment | $420 | $680 (assumes 20% down) |
| Total paid over 3 years | $15,120 | $24,480 |
| Down payment / due at signing | $2,500 | $7,600 (20%) |
| Equity at 3-year mark | $0 | ~$16,000 (car value) |
| Net cost after resale (if sold) | $17,620 | ~$16,080 |
Even though the lease's raw monthly outlay is lower, once you account for the equity a buyer builds and could recover by selling the car, buying comes out roughly comparable or ahead at the 3-year mark - and dramatically ahead if you keep driving the car past year 3 with no more payments at all.
The Mileage Trap
Leases typically cap mileage at 10,000-12,000 miles/year, with overage fees of $0.15-$0.30 per mile charged at lease-end. A driver who actually puts on 15,000 miles/year on a 12,000-mile lease racks up 9,000 excess miles over a 3-year term - that's $1,350-$2,700 in fees due all at once when they turn the car in. If your commute or lifestyle involves regular long drives, this alone can flip the math against leasing.
When Leasing Actually Wins
Leasing makes sense if you: want a new car every 2-3 years with the latest safety tech, drive consistently under 12,000 miles/year, can deduct lease payments as a business expense (self-employed / business use), or simply want to avoid the hassle of selling or trading in a car. It also avoids most major repair costs since leased cars are usually under warranty for the full term.
When Buying Actually Wins
Buying wins for high-mileage drivers, anyone planning to keep a car 6+ years (loan payments stop, lease payments never do), and anyone who wants to build an asset rather than pay indefinitely. The break-even is typically around years 4-5: that's when a paid-off owned car with no monthly payment starts to meaningfully beat a lease-forever cycle.
