Lease vs Buy Car Calculator — Which Option Actually Costs Less?

The lease vs. buy debate never has a single right answer — it depends on how much you drive, how long you keep cars, what you value, and your financial situation. But the math has a right answer for your specific numbers. The lease vs. buy car calculator on CalcHub compares total cost of ownership across both options so the decision is based on numbers, not a salesperson's pitch.

What Leasing Actually Is

Leasing means you're financing the depreciation — not the whole car. If a $40,000 car has a residual value of $24,000 after 3 years, you're essentially financing the $16,000 difference (plus fees and interest). Monthly payments are lower because you're not paying for the full vehicle.

The tradeoff: you own nothing at the end. You also have mileage limits (typically 10,000–15,000 miles/year) and condition requirements.

Side-by-Side Comparison Example

Scenario: $40,000 vehicle, 3 years / 36,000 miles, 6% financing rate

Lease	Buy
Down payment	$2,000	$2,000
Monthly payment	~$380	~$1,150
36-month payments	$13,680	$41,400
End-of-term equity	$0	~$24,000 (residual)
Net 3-year cost	~$15,680	~$19,400

The lease wins over 3 years in this example. But buy another car at the end of the lease and you pay the same entry costs again. Keep the purchased car another 3–4 years and the math flips — by year 6, you own an asset with zero monthly payment.

When Leasing Makes Sense

• You want a new car every 2–3 years
• You drive moderate mileage (under 15,000/year)
• You use the car for business (lease payments may be tax-deductible)
• The car is used as a business vehicle where the latest tech or appearance matters

When Buying Makes Sense

• You drive high mileage (15,000+ miles/year — mileage penalties on leases are brutal)
• You keep cars long-term (5+ years)
• You want to modify the vehicle
• You want zero monthly payment eventually

All calculations are estimates. Actual costs depend on negotiated selling price, money factor, residual value, taxes, registration, and terms specific to your deal and location.

What is the "money factor" in a lease?

Money factor is essentially the lease interest rate expressed differently. Multiply the money factor by 2,400 to convert it to an approximate APR. A money factor of 0.00175 = roughly 4.2% APR. Dealers don't always disclose this clearly, which is why knowing the conversion is useful.

Are there hidden costs in leasing?

Several common ones: acquisition fee (usually $500–$1,000 at signing, often buried), disposition fee at lease end ($300–$500 if you don't buy or re-lease), excess wear charges, and mileage overage fees ($0.15–$0.30 per mile over the limit). These can turn a seemingly cheaper lease into something less favorable.

Should I put a large down payment (capitalized cost reduction) on a lease?

Generally no. Unlike buying, a large lease down payment is consumed by the lease and is lost if the car is totaled in month one. Insurance covers the vehicle value, not the money you put into the lease upfront. A smaller down payment on a lease keeps your risk exposure lower.
