- Buy net cost = down payment + total loan payments − residual value at end of ownership period. Residual value uses compound depreciation:
price × (1 − annual rate)^years. - Lease net cost = drive-off fee(s) + total monthly payments. If the ownership period spans more than one lease term, the driver is assumed to re-lease at the same terms (each with a new drive-off fee).
- Maintenance, insurance, fuel, and registration are excluded — they're roughly equal between scenarios for the same car.
- The opportunity cost of the down payment (investing it instead) is not modeled. If you'd invest a large down payment, buying looks less favorable.
Leasing vs. buying: the real math
Car dealers heavily promote leasing because it's more profitable for them. You pay less in monthly payments, but you never build equity and you're locked into a new payment every few years forever. Buying a car and keeping it for 10+ years is almost always cheaper over the long run, but leasing has real advantages for certain drivers.
The key comparison isn't monthly payments — it's total cost of ownership. A lease might be $200/month cheaper than a buy, but after 3 years you own nothing. A 3-year lease cycle costs roughly $10,000–$15,000 in total payments with nothing to show for it. A comparable loan payment of $400/month over 5 years might cost more per month, but after the loan is paid off you have a car payment of $0 for the remaining 5 years of that cycle.
Why it matters to your money
Cars are typically the second-largest expense after housing. Over a 30-year driving career, the total cost of perpetual leasing or buying new can easily exceed $300,000. Understanding the real cost difference between leasing and buying helps you make a decision based on numbers, not dealer pressure or the allure of a new car every few years.

Rules of thumb
- Buying and keeping 10+ years wins: After the loan is paid off, you have $0 car payments for years. This strategy saves the most over a lifetime.
- Leasing makes sense when: You drive under the mileage limit, want warranty coverage on every car, or can deduct payments as a business expense. For most personal-use drivers, buying wins.
- Buy 2–3 year old used cars: They've absorbed the steepest depreciation (15–25% in year one) while still having most of their useful life ahead. This is the single biggest money-saver on car ownership.
Frequently asked questions
- Is leasing or buying a car cheaper?
- Leasing typically has lower monthly payments but you own nothing at the end. Buying costs more monthly but builds equity. Over multiple vehicle cycles (10+ years), buying and keeping a car long-term is almost always cheaper than perpetually leasing.
- What is a money factor in a car lease?
- The money factor is the lease equivalent of an interest rate. Multiply it by 2,400 to get the approximate APR. A money factor of 0.0025 equals roughly 6% APR. Always compare the money factor to a loan APR before deciding.
- What are the hidden costs of leasing?
- Mileage overage fees (typically $0.15–0.30 per mile over the limit), wear-and-tear charges at turn-in, disposition fees (~$300–$500), and the fact that you repeat acquisition costs every few years.
- When does leasing make financial sense?
- Leasing can make sense for business owners who can deduct payments, drivers who want a new car every 3 years, or in markets with very favorable residual values and money factors. For most personal use, buying a reliable used car outright wins financially.
