Leasing vs Buying: How to Know Which One Is Right for You

The answer isn’t emotional. It’s mathematical. Here’s the exact math dealers don’t explain — and how to run the real numbers on your specific situation.

The Short Version

✓Leasing wins if you drive <12K miles/year, want a new car every 2–3 years, and want zero maintenance hassle.
✓Buying wins if you drive >15K miles/year, keep cars 5+ years, want to customize, or want to build equity.
✓The money factor in a lease is just an APR in disguise — multiply it by 2,400 to compare apples to apples against a loan.
✓A 72–84-month purchase loan is functionally a worse version of leasing, without the end-of-term flexibility. The gap rolls forward.
✓Run a 6-year total cost comparison: 3-year lease + 3-year lease vs. 6-year ownership. The math never lies.

The lease-versus-buy question doesn’t have a universal answer. There’s no moral high ground here. There’s only total cost of ownership — and whether that math favors having the car for a fixed period, returning it, and moving on, or holding it long enough that you own it free and clear.

Most people decide based on monthly payment alone. Dealers love that. It costs them nothing to lower the payment — they just stretch the term, roll in old debt, or add gap insurance. You walk out thinking you won when you actually just borrowed more.

The right decision is built on three numbers: your annual miles, your hold-time horizon, and your total out-of-pocket cash over six years. Not the monthly payment. Not the lease residual. Total cash out.

If you’re confused, you’re losing. Clarity = control.

When leasing wins

You drive under 12,000 miles per year

Lease mileage overages run $0.15–$0.30 per mile. Overage fees add up to $500–$1,500 per extra 5,000 miles. If your actual usage is below 12K/year consistently, leasing caps your mileage cost. A buyer with high miles pays that cost in depreciation — but the lease locks it in the contract.

You want a new car every 2–3 years

Leases are designed to end. No residual risk, no surprise repair bills when the warranty expires, no hassle selling a used car with 60,000 miles. You give the car back to the dealer and walk away. Psychologically and financially, that's clean.

You use the car for business

Lease payments are often fully tax-deductible (consult your CPA — the IRS draws a distinction between vehicle leases and personal leases). The write-off mechanics can make a $500 monthly payment actually cost you $350–$400 after-tax. That advantage evaporates the moment you buy.

You want zero maintenance hassle

Manufacturer warranty covers 3 years and unlimited miles on a lease. No timing belt, no brake pads, no transmission fluid changes — the dealer handles it all under warranty. For a busy person or someone who doesn't want to think about car maintenance, that's valuable.

The residual value is artificially inflated

Manufacturers sometimes subsidize lease residuals to push volume on new models. When the residual is artificially high (because the manufacturer wants to move 2024s before 2025s arrive), the lease payment drops below market. That's a real win. Most of the time, residuals are fair — sometimes dealers use inflated residuals to hide a bad lease rate.

When buying wins

You drive over 15,000 miles per year

Once you cross 15K annual miles, the lease overage fees cost more per mile than the depreciation hit on a purchase. You're paying the same loss of value either way — but in a lease, you pay it via penalty. In a purchase, you pay it via the market. The purchase is cheaper.

You keep cars 5+ years

The longer you hold a car, the more you amortize the fixed costs (sales tax, insurance premiums). A car paid off at year 5–6 costs dramatically less over years 6–8 when you own it free. A lease never gives you that. You always have a payment.

You want to modify or customize the vehicle

Lease agreements are clear: no aftermarket wheels, no suspension work, no interior modifications without dealer approval. If you want to change the car — new exhaust, tint, stereo, wheels — buying is the only path. A lease is a rental, not ownership.

You want to build equity and own free eventually

A purchase always has an endpoint. At 6–7 years, the car is yours and the payment is gone. You can keep driving it for another 5–10 years with zero payment. A lease is perpetual. You trade every 3 years and start a new payment. Over 12 years, that's four leases instead of one paid-off purchase.

You're financing at a reasonable rate

If your credit is solid and the interest rate is 5–6%, a purchase usually beats a lease over 6+ years. The breakeven is roughly 5 years, 60,000 miles. Longer hold or higher mileage = purchase wins. Shorter hold or lower mileage = lease is competitive.

The hidden math dealers don't explain

Dealers lean on opaque terms to hide the real cost of a lease. Here's what to watch:

Money factor vs. APR

A lease quotes you a "money factor" (e.g., 0.0015) instead of an APR. The number is purposefully obscure. To translate it to APR, multiply by 2,400. A 0.0015 money factor = 3.6% APR equivalent. If that feels high compared to current loan rates, it is. You're paying a premium just for the lease structure.

Disposition fee at lease-end

Most leases include a $395–$595 "disposition fee" at the end to cover the dealer's cost of inspecting and selling your lease return. It's buried in the fine print. On a three-year lease, that fee is baked into your monthly cost math, even though you don't pay it until year 3.

Mileage overages ($0.15–$0.30 per mile)

Lease contracts specify annual mileage (typically 10K, 12K, or 15K). Every mile over that limit costs $0.15–$0.30. If you drive 15K miles per year but your lease is capped at 12K, you're overage by 36,000 miles over three years. That's $5,400–$10,800 in penalties. The lease payment looked reasonable until that bill arrives.

Gap between residual and market value

The lease residual is the car's value at lease-end per the contract. If the residual is 55% of MSRP but the car's actual market value at lease-end is 52%, the gap isn't your problem — the leasing company absorbs it. But if the residual is 50% and market value is 45%, the leasing company has a loss. They pass it to lessees via higher lease rates on their next deal. Over time, inflated residuals = higher future payments.

The "easy" lease trap

Leasing feels "easy" because you have a $400 payment and no other car costs (warranty covers it). But if you string together three back-to-back three-year leases, you've paid nine years of car payments ($43,200 at $400/month) with zero equity. Over the same nine years, a financed purchase at $450/month is paid off by year 6–7, then costs you ~$100/month in insurance and maintenance. The lease is seductive because it hides the compounding cost of perpetual payments.

The insider rule for this decision

Stop comparing monthly payments. Compare total cost over six years. Here's how:

Scenario A: Two 3-year leases back-to-back

Lease 1 (36 months): $400 × 36 = $14,400
Lease acquisition fees (2 × $695): $1,390
Disposition fees (2 × $495): $990
Registration/doc fees (2 × $200): $400
Insurance (est. $120/month × 72): $8,640
Maintenance (covered; minimal): $200
Total 6-year cost: ~$26,020

Note: Does not include mileage overage fees. If you exceed 12K miles/year by 3K miles/year, add $5,400–$10,800.

Scenario B: 6-year financed purchase

Car price: $35,000 (let's use the same type of car)
Down payment (10%): -$3,500 (reduces financed amount)
Loan amount: $31,500
Monthly payment at 5.5% APR / 72 months: ~$485/month
Total payments (72 × $485): $34,920
Registration/doc/title: $300
Insurance (est. $140/month × 72): $10,080
Maintenance years 1–5 (warranty): $500
Maintenance year 6 (post-warranty): $1,500
Estimated residual at 6 years (45% of $35K): -$15,750 (you can sell it or trade it)
Total net cost after sale: ~$31,550

At year 6, you own the car free. Years 7–8, you have zero payment (insurance + maintenance only). Over 8 years, your cost per month drops to ~$200.

The verdict: In this example, the lease costs ~$26K over 6 years. The purchase costs ~$32K (before residual credit), but you own the car. If you keep it 8 years instead of trading at year 6, the purchase amortizes to ~$30K total (paid off at year 6, near-free in years 7–8). The lease would cost $39K over 8 years if you sign a third lease. The break-even point is roughly 5–6 years of ownership.

Why a 72–84-month loan is a trap

One objection we hear: "But I could just get a long loan instead of leasing." Don’t. An 84-month loan is functionally a worse version of leasing — you get the worst parts of both with none of the upside.

At month 36, a $40,000 truck financed at 84 months and 5.5% APR has a payment of ~$650/month and a loan balance of ~$27,500. The car's actual market value is ~$22,000. You're underwater by $5,500. Unlike a lease, that gap doesn't disappear at lease-end — it gets rolled into your next purchase, whether that next deal is a lease or another loan. This is the negative equity cycle in action. Rinse and repeat.

You also own all the maintenance risk after the 3-year warranty expires. And the 84-month term means you're paying interest for seven years on a depreciating asset. The total interest paid is often $14,000–$18,000 on a $40,000 truck.

A 60–72-month loan is more defensible (you own it by year 5–6, avoiding the negative-equity trap). But an 84-month loan puts you in payment purgatory. You're not building equity — you're just delaying the bill.

Still stuck in negative equity?

If you're upside-down on your current car, the 84-month trap is how you stay there. Read the deep dive on negative equity to break the cycle before your next trade.
