The Perpetual Leaser Pays 30 to 40% More Over a Decade
The average new vehicle transaction price hit $49,758 in June 2026, according to Kelley Blue Book. The average lease payment was $613 per month in Q4 2025, according to Experian's State of the Automotive Finance Market report. The average new car loan payment was $767. On the surface, leasing looks cheaper: $613 versus $767 for the same vehicle in your driveway.
But the lease payment comparison only works for the first 36 months. The perpetual leaser chains one 3-year lease to the next indefinitely. They always have a car payment and never build equity. The buyer takes out a 5-year auto loan, makes 60 payments, then drives the car payment-free for years 6 through 10 and beyond. Over a decade, the buyer typically spends 30 to 40% less in total net cost than the continuous leaser, according to lease-vs-buy analyses from Edmunds.
The calculator above runs the full math in both directions so you can see the total cost of each path over a time horizon you choose.
How a Car Lease Actually Works
A lease is a rental agreement with a residual value attached. You pay for the depreciation of the vehicle during the lease term, plus a financing charge called the money factor (the lease equivalent of an interest rate), plus taxes and fees.
Capitalized cost is the negotiated price of the vehicle, analogous to the purchase price. This is negotiable and directly affects your payment. Most consumers do not negotiate the cap cost on a lease, which is a significant financial error.
Residual value is the predicted value of the car at the end of the lease term, expressed as a percentage of MSRP. A car with a 54% residual after 36 months holds its value well and will have a lower lease payment than a car with a 40% residual, because you are financing less depreciation.
Money factor is the financing cost, expressed as a small decimal (e.g., 0.0032). Multiply by 2,400 to convert to an approximate APR equivalent. A money factor of 0.0032 is roughly equivalent to a 7.7% interest rate.
The monthly payment formula (simplified):
Monthly payment = (Depreciation per month) + (Finance charge per month)
Where depreciation per month = (Cap cost - Residual) / Lease term in months
And finance charge per month = (Cap cost + Residual) x Money factor
Fees, acquisition fees, and taxes add to this base calculation and vary by state and dealer.
The Mileage Problem
The most common financial mistake in leasing is underestimating annual mileage. Standard lease agreements allow 10,000 to 15,000 miles per year. The average American drives 13,500 miles per year, according to the Federal Highway Administration. Excess mileage charges typically run $0.15 to $0.30 per mile over the limit.
A driver who puts 15,000 miles per year on a car with a 12,000-mile annual allowance accrues 9,000 excess miles over a 3-year lease. At $0.25/mile, that is $2,250 in overage charges due at lease return. This single factor can eliminate any payment advantage the lease appeared to offer.
If you drive more than 15,000 miles per year, leasing is almost always the more expensive option and becomes progressively worse as mileage increases.
The Long-Term Cost of Perpetual Leasing
The most significant financial argument against leasing is what happens when you compare long-term paths.
The perpetual leaser chains one 3-year lease to the next indefinitely. They always have a car payment, always have a new car, and never build equity. Over 10 years, they make 120 monthly payments with nothing to show for it at the end except a return receipt.
The buyer takes out a 5-year auto loan, makes 60 payments, then drives the car payment-free for years 6, 7, 8, 9, and 10. During those payment-free years, they have $500 to $700 per month freed up that they can invest, save, or use however they choose.
Here is a 10-year comparison on a $42,000 vehicle:
| Strategy | Monthly Cost | Total Spent (10 yrs) | Asset Value at Year 10 |
|---|---|---|---|
| Perpetual leasing (3x 36mo) | ~$520/mo for 120 months | ~$62,400 | $0 |
| Buy and hold (60mo loan) | ~$712/mo for 60 months, then $0 | ~$42,720 | ~$8,000 to $12,000 |
The buyer comes out ahead by roughly $27,000 to $32,000 over 10 years. That gap grows the longer you keep the vehicle after paying off the loan. If you invested the $520/month payment difference during years 6 through 10 at a 7% return, you would accumulate roughly $36,000 more on top of the vehicle equity.
When Leasing Makes Financial Sense
Despite the long-term cost disadvantage, leasing is the better financial choice in specific circumstances:
Business use. If you use the vehicle for business and can deduct the lease payments as a business expense, the tax advantages can make leasing the more efficient option. The deductibility depends on your business structure and the percentage of business use.
Short holding periods. If you reliably replace your car every 2 to 3 years regardless, leasing avoids the transaction costs and depreciation exposure of buying and quickly reselling. You never own a car that has dropped 20% the moment you drove off the lot.
Manufacturer subsidized leases. Automakers frequently subsidize leases with inflated residual values and reduced money factors to move inventory. A heavily subsidized lease (look for money factors well below the equivalent market interest rate and residuals above 55-60%) can produce monthly payments significantly below what financing the same car would cost.
Very low mileage drivers. Under 10,000 miles per year, the mileage penalty risk disappears and leasing becomes more competitive.
Technology upgrade priority. For people who genuinely value driving the latest safety technology or fuel efficiency improvements every 3 years, leasing provides a predictable upgrade cycle without the hassle of selling.
The Depreciation Reality of New Car Buying
Buying a new car has its own hidden cost: immediate depreciation. New cars lose approximately 20% of their value in the first year and another 10-15% in years two and three. A $40,000 new car is worth roughly $26,000 to $28,000 after three years of average use.
This depreciation is a real cost even if it is invisible. When you finance a new car, you are paying interest on a loan for an asset that is simultaneously losing value. In the first two years of a typical auto loan, most of your monthly payment goes toward interest rather than principal, while the car itself is depreciating fastest.
The optimal financial strategy for most consumers is neither leasing new cars perpetually nor buying new cars frequently. It is buying a 2 to 4 year old used car (letting someone else absorb the steepest depreciation curve) with cash or a short loan, then driving it for 8 to 12 years. This strategy produces the lowest total lifetime transportation costs by a significant margin.
True Cost of Ownership Beyond the Payment
Whether leasing or buying, the true monthly cost of a vehicle includes expenses beyond the payment:
Insurance: Leased vehicles require comprehensive and collision coverage with lower deductibles than lenders often require. Expect $100 to $200/month for full coverage depending on your profile and location.
Maintenance: New cars under warranty have lower maintenance costs. Older owned vehicles have higher maintenance costs. Leased vehicles require you to maintain the car to factory standards to avoid wear-and-tear charges at return.
Fuel: Consistent regardless of how you finance the vehicle, but affects total cost of ownership comparisons between models.
Registration and taxes: Vary by state. Some states tax leased vehicles differently than owned vehicles.
Real-World Examples
Example: Priya, considering a $42,000 SUV
Lease option: 36-month lease, $4,500 drive-off, $520/month payment, 12,000 miles/year allowed.
Buy option: $42,000 purchase, $4,500 down, 60-month loan at 7.0% (the Q2 2026 average), $832/month payment.
Priya drives 14,000 miles/year.
Lease 3-year cost: $4,500 + (36 x $520) + (6,000 excess miles x $0.25) = $4,500 + $18,720 + $1,500 = $24,720. Car returned, no asset.
Buy 3-year cost: $4,500 + (36 x $832) = $4,500 + $29,952 = $34,452. Car worth approximately $22,000. Net cost = $12,452.
Result: Buying costs $12,452 net after 3 years versus $24,720 for leasing. Priya buys.
Example: Marcus, 10-year total cost comparison
Perpetual leasing: $520/month for 120 months = $62,400 out of pocket, no asset.
Buy and hold: $832/month for 60 months ($49,920 total), then payment-free for 60 months. Total: $49,920. Car worth $8,000 to $12,000 at year 10. Net: approximately $38,000 to $42,000.
Result: Marcus saves $20,000 to $24,000 over 10 years by buying and holding. If he invests the $312/month payment difference during years 6 through 10 at 7%, he accumulates another $21,500.
Common Pitfalls
Underestimating mileage. The average driver exceeds the standard 12,000-mile lease cap. Calculate your actual annual mileage from your odometer or insurance records before assuming a lease works for you.
Not negotiating the capitalized cost. The cap cost is negotiable on a lease, just like the purchase price when buying. Most lessees accept the sticker price without negotiating, which inflates every payment for 36 months.
Ignoring wear-and-tear charges. Lease returns are inspected for damage. Normal wear is allowed, but dents, scratches, tire wear, and interior damage can trigger $500 to $2,000 in fees at return.
Comparing only monthly payments. A $520 lease payment versus a $712 loan payment looks like leasing wins. But after 5 years, the buyer owns an asset worth $17,000 and the leaser owns nothing. Compare total net cost, not monthly payment.
