Long-Term Cost Comparison (3 Lease Cycles vs 1 Buy)

Compares 9 years of leasing (three 3-year leases) vs buying one car and keeping it for 9 years.

Net Cost Over Time

Buy net cost = cumulative paid − current car value. Leasing = cumulative payments with no equity offset.

Frequently Asked Questions

Strategy Is it better to lease or buy a car?
It depends on your situation. Buying and keeping a car for 7-10 years almost always wins financially. Leasing makes sense if you drive fewer than 12,000 mi/year, value always having a new car with warranty, or need lower monthly payments for cash flow.
Basics How is a lease payment calculated?
Lease payment = Depreciation Fee + Finance Fee + Tax. Depreciation = (Adjusted Cap Cost - Residual) / Term Months. Finance Fee = (Cap Cost + Residual) x Money Factor. Money Factor x 2400 = equivalent APR.
Basics What is a good money factor?
Money factor x 2400 = APR. A factor of 0.00125 equals 3% APR. Anything above 0.0033 (8% APR) is high. Always ask the dealer for the money factor and compare to current loan rates.
Advanced What happens if I exceed the mileage limit?
Most leases charge $0.15-$0.25 per excess mile. Driving 3,000 miles over at $0.20/mile costs $600 at lease end. If you routinely exceed your limit, buying or negotiating a higher-mileage lease is cheaper.
Advanced Can I negotiate a lease?
Yes. You can negotiate the cap cost (selling price), money factor, and sometimes the mileage allowance. The residual is set by the manufacturer. Lowering the cap cost has the biggest impact on your monthly payment.
Strategy Should I put money down on a lease?
Generally no. If the car is totaled or stolen, you typically lose any cap cost reduction. It is usually better to keep cash and pay higher monthly payments, or put that money in an interest-bearing account.
Basics What is residual value and why does it matter?
Residual value is the car's estimated worth at lease end. Higher residual means lower payments because you finance less depreciation. Toyota, Honda, and Subaru tend to have strong residual values.

Formula & Methodology

Lease Monthly Payment
Payment = Depreciation Fee + Finance Fee + Tax
Depreciation = (Cap Cost - Residual) / Months. Finance = (Cap Cost + Residual) x Money Factor.
Total Lease Cost
Total = (Monthly x Months) + Cap Reduction + Acq Fee + Dis Fee + Overage
Includes all upfront, monthly, and end-of-lease costs with no equity at the end.
Buy Monthly Payment (PMT)
PMT = P x [r(1+r)^n] / [(1+r)^n - 1]
P = loan amount, r = monthly rate, n = months. Standard amortizing loan formula.
Net Buy Cost
Net Cost = Total Paid - Vehicle Value at End
Subtracts the car's residual market value from total payments to find the true cost of ownership.
📖

Key Terms Explained

Residual Value The predicted vehicle worth at lease end, set by the leasing company. Higher residual = lower monthly payments because you finance less depreciation.
Money Factor The lease equivalent of an interest rate. Multiply by 2,400 to convert to APR. A money factor of 0.00125 equals roughly 3% APR.
Capitalized Cost The negotiated vehicle price used as the basis for lease payment calculation. Equivalent to the sale price in a purchase. Lower cap cost = lower payments.
Depreciation The loss in vehicle value over time. New cars lose 15-25% in year one. Lease payments are essentially prepaid depreciation for the lease period.
GAP Insurance Guaranteed Asset Protection covers the difference between what you owe on a loan/lease and the vehicle's actual cash value if totaled or stolen.
Disposition Fee A fee charged at lease end when you return the vehicle, typically $300-$500. Waived if you lease another vehicle from the same brand.

3-Year Lease vs 5-Year Buy

$35,000 sedan. Lease: $450/mo x 36 + $2,500 down = $18,700 total, walk away. Buy: $550/mo x 60 + $2,500 down = $35,500 total, own car worth ~$18,000. Net buy cost after selling: $17,500. Lease wins for 3-year comparison; buying wins at 5+ years.

Leasing vs Buying a Car: Which Is Right for You?

A lease payment is essentially rent for depreciation — you pay for the portion of the car's value you consume during the lease term. On a $40,000 car with a 55% residual value after 3 years, you are financing $18,000 in depreciation (plus fees and interest), not the full $40,000. This is why monthly lease payments are typically 30-40% lower than purchase payments for the same vehicle.

While monthly lease payments look attractive, several hidden costs can add up: excess mileage fees ($0.15-$0.30 per mile over the limit), wear-and-tear charges at lease return, acquisition fees ($500-$1,000 upfront), disposition fees ($300-$500 at lease end), and gap insurance. Over a 3-year lease, these extras can add $3,000-$7,000 to the real cost.

If you plan to keep a vehicle for 7+ years, buying almost always wins financially. Once you pay off the loan, you own a depreciating but real asset with no monthly payment. A car paid off at year 5 and driven to year 10 effectively costs nothing in financing for those final 5 years. Leasing never ends — you are always making payments. For most financial planners, long-term buying with a reliable vehicle is the wealth-maximizing choice.

The money factor is one of the most misunderstood aspects of leasing. Dealers are not required to disclose it, and many consumers do not know to ask. To convert a money factor to APR, multiply by 2,400. A money factor of 0.00271 equals 6.5% APR. Some dealers inflate the money factor above the manufacturer's base rate as a profit source, so always ask for the "buy rate" money factor and compare it to current auto loan APRs.

Negotiating a lease follows the same principles as negotiating a purchase — the lower the capitalized cost, the lower your payment. Many consumers mistakenly focus only on the monthly payment, which dealers can manipulate by adjusting term length, down payment, or residual. Always negotiate the cap cost first, then verify the money factor and residual are at manufacturer rates before agreeing to a deal.

For drivers who want a new car every 2-3 years and drive fewer than 12,000 miles annually, leasing can be the more practical choice. You always have warranty coverage, maintenance is often included or minimal, and you avoid the hassle of selling a used car. The total cost may be higher over 10 years, but the convenience and lower cash outlay each month appeal to many buyers.
