Car Lease vs. Buy: Total Cost of Ownership Breakdown
Choosing between leasing and buying a car in the United States comes down to whether you prioritize lower monthly payments or long-term equity accumulation.
How Leasing Works
When you lease a car, you are paying for the vehicle's expected **depreciation** during the lease term (typically 36 months), plus a finance charge known as the **money factor**. At the end of the lease, you return the vehicle to the dealership with zero residual equity.
How Buying & Financing Works
When you buy a car with an auto loan, your monthly payments are higher because you are paying off the entire vehicle purchase price. However, at the end of the loan, you own an asset that retains significant resale value.
Worked Example: $35,000 Vehicle (3-Year Comparison)
| Category | Buying ($35,000 Price) | Leasing ($400/mo Lease) |
|---|---|---|
| Down Payment / Drive-Off | $3,000 | $2,000 |
| Monthly Outflow | $618 (5-Yr Loan at 6%) | $400 / Month |
| 3-Year Out of Pocket | $25,248 | $16,400 |
| Asset Value at 3 Years | +$21,490 (Car Equity) | $0 (Returned) |
| Net 3-Year Cost | $14,558 | $16,400 |
Frequently Asked Questions (FAQ)
What is the money factor in a car lease?
The money factor is the interest rate on a lease. To convert a money factor to an equivalent annual percentage rate (APR), multiply the money factor by 2,400.
What happens if I exceed my lease mileage limit?
Standard US lease agreements allow 10,000 to 12,000 miles per year. Exceeding this limit incurs penalties ranging from $0.15 to $0.30 per excess mile.

What is the US Car Lease vs. Buy Calculator?
The US Car Lease vs. Buy Calculator is a total cost of ownership modeler designed to help auto buyers evaluate the long-term financial difference between leasing and buying a car.
Deciding between leasing and buying involves comparing two entirely different ownership models:
• Buying a Car (Financing/Cash): You own the vehicle. Monthly loan payments build equity. Once the loan is fully paid off, you own an asset that you can keep driving or sell. However, cars are depreciating assets (typically losing 15% to 20% of their value per year). The net cost of buying is calculated as the total purchase costs minus the vehicle's remaining residual market value at the end of your analysis period.
• Leasing a Car: You are essentially renting the vehicle for a fixed term (usually 36 months). You pay for the vehicle's depreciation during that period, plus financing charges (known as the money factor).
- Pros: Lower monthly payments, drive a new car under warranty, and avoid selling hassles.
- Cons: You do not build equity, you must pay "drive-off" acquisition fees, and you face potential penalties for exceeding mileage allowances (typically $0.20 to $0.25 per mile over 10,000–12,000 miles/year) or excessive wear-and-tear.
This calculator models both options side-by-side over the same analysis timeframe, accounting for loan rates, depreciation, lease payments, down payments, and mileage limits to determine the lowest total cost option.
How Does the US Car Lease vs. Buy Calculator Work?
Enter car price, down payment, loan rate and term for buying. Then enter lease payment, term, and mileage overage details. Results compare total out-of-pocket costs net of depreciation.
Formula & Calculation Method
Buy cost = total loan paid + down payment - car residual value at end of lease term (using depreciation rate). Lease cost = down + monthly payments × months + mileage fees at $0.25/mile.
Example Calculation
Buying a $35,000 car with a 5-year loan at 6% vs. leasing at $400/month for 3 years is compared, accounting for 15% annual depreciation.
