Should You Lease or Buy a Car?

Short answer: leasing usually costs less per month and less over the first few years, while buying usually wins over a decade because the payments stop. The right choice depends on your mileage, how long you keep cars, and whether you value cash flow or wealth. Here is how to decide with numbers instead of gut feeling.

Walk into a dealership with "should I lease or buy?" and you will get an answer shaped by what the dealer wants to sell you that month. The question deserves better than a sales pitch, because it is really two questions wearing one coat: which costs less? and which fits your life? The first one is pure math. The second one is about mileage, patience, and how you feel about car payments as a permanent roommate.

The real tradeoff: equity vs flexibility

When you buy — with cash or a loan — every payment buys a slice of the car. Once the loan is gone, you own a machine worth thousands that costs you nothing per month to keep. That ownership is equity, and it is the entire financial case for buying.

When you lease, you pay for the car's depreciation during your term plus a finance charge — then hand back the keys with zero equity. What you get instead is flexibility: a lower payment, a new car every few years, warranty coverage throughout, and no gamble on resale value. Neither side is "throwing money away": the buyer pays more per month to build equity, the lessee pays less and keeps the difference. The honest comparison puts both totals side by side over the same horizon.

How to compare lease vs buy fairly

Step 1 — Price the same car on both sides. Compare the lease quote and the loan for the identical vehicle, or the numbers lie. Use the same selling price and a similar down payment so the only difference is the financing structure.

Step 2 — Decode the lease into a monthly payment. A lease payment is depreciation plus rent charge: (cap cost − residual) ÷ term, plus (cap cost + residual) × money factor. Multiply the money factor by 2,400 to get its approximate APR, so you can judge whether the lease's hidden rate is fair next to loan rates.

Step 3 — Total the out-of-pocket at 3 and 5 years. Add the down payment, every monthly payment, and the lease's acquisition and disposition fees. The side with the smaller total at your horizon is the cheaper way to drive for that long — but remember that past the loan's last payment, the buyer coasts payment-free while the lessee signs another lease.

The money factor, decoded

The money factor is the lease industry's way of quoting an interest rate without calling it one. It looks tiny — 0.00208 — and that is the point: hardly anyone multiplies it by 2,400 in the showroom to discover it means roughly 5.0% APR. The rent charge it produces is (cap cost + residual) × money factor, billed every month: on a $35,000 cap cost with a $20,900 residual, that is about $116.27 a month. Always ask for the factor in writing, convert it, and compare it to loan APRs before you sign.

Worked example: a $38,000 car over 3 years

Same car, $3,000 down on both sides. The lease: 36 months, money factor 0.00208 (≈5.0% APR), 55% residual, $595 acquisition and $395 disposition fees. The loan: 6.9% APR for 60 months.

The lease payment is $507.94 a month — $391.67 of depreciation plus $116.27 of rent charge. The loan payment is $691.39 a month, $183.45 more. After 3 years the lease has cost $22,275.79 out of pocket (down payment, acquisition fee, 36 payments, disposition fee) while the loan has cost $27,890.11 (down payment plus 36 payments). Leasing wins the 3-year horizon by $5,614.31.

Stretch to 5 years and the lease rolls into a second term: $38,061.32 total vs $44,483.51 for the loan — leasing still ahead by $6,422.19. But at month 60 the loan dies and the buyer owns the car outright while the lessee starts a third lease. By year 8 the buyer has spent $44,483.51 total and the perpetual lessee $60,337.11, with the crossover around year 6. That bend in the curve is the whole story: leases win sprints, ownership wins marathons.

Decision checklist

Mileage. Under ~12,000 miles a year, a lease's allowance fits. At 18,000+, overage fees (often 15–30¢ a mile) eat the lease's advantage — buy instead, or negotiate a high-mileage lease up front.

How long you keep cars. Bored every three years and always want a new car under warranty? Leasing matches the habit and is often cheaper than buying new every three years. Drive cars for a decade? Buying and holding is the runaway winner.

Cash flow vs wealth. A tight monthly budget favors the lease's lower payment — the $183-a-month gap in the example is real money. But that gap buys equity on the loan side. Lease for breathing room now, buy for net worth later.

Down payment discipline. Big down payments on leases are risky: if the car is totaled early, that upfront money is gone while GAP coverage handles the rest. Keep lease drive-off costs small; save the big down payment for a purchase.

Business use. Lease payments are often simpler to deduct than depreciation schedules if you use the car for work. Talk to a tax pro — this is one case where the paperwork tilts toward leasing.

Frequently asked questions

Is leasing ever the smarter financial move, not just the convenient one?

Yes, in specific cases: when you would buy a new car every 3–4 years anyway (perpetual new-car buyers often spend less leasing), when a manufacturer subsidizes the lease with an inflated residual or near-zero money factor, and when you can deduct the payments for business use.

Can I negotiate the money factor?

The base factor is set by the leasing company, but dealers may mark it up — and many do. Ask for the "buy rate," convert both to APR with the ×2,400 rule, and treat any markup like the price increase it is. The selling price, fees, and mileage allowance are negotiable too.

What happens if the car is worth less than the residual at lease end?

Nothing bad — that is the leasing company's problem, and one of the lease's hidden perks. You hand back the keys and walk away. The flip side: if the car is worth more than the residual, capture the difference by buying at the contract price or trading it in.

Should I put money down on a lease?

As little as possible. A down payment lowers the monthly payment but barely changes the total — and if the car is stolen or totaled in month two, that upfront cash is simply gone. Keep drive-off to the first payment and required fees.

Does leasing build credit like a loan does?

Lease payments are reported to the bureaus and on-time payments help your score, much like a loan. But a lease builds no equity, and an installment loan paid in full is the stronger record for pure credit-building.

What credit score do I need to lease?

The best money factors generally go to scores around 700 and up; below that, expect a marked-up factor or a declined application. With a borderline score, a loan — where rates are transparent and shoppable — may price better than a marked-up lease.
