Understanding Your Car Lease Calculation

Leasing a vehicle is often compared to a long-term rental, but the math behind it is more complex than a standard loan. Unlike a purchase, where you pay for the entire value of the car, a lease only charges you for the portion of the vehicle's value that you "use up" during the lease term.

Key Terms Explained

• Gross Capitalized Cost: This is the negotiated price of the vehicle plus any fees or taxes rolled into the lease.
• Residual Value: The estimated value of the car at the end of the lease. This is set by the leasing company and expressed as a percentage of the original MSRP.
• Money Factor: This represents the interest rate on the lease. To convert a money factor to a standard APR, multiply it by 2400.
• Cap Cost Reduction: Anything that lowers the amount being financed, such as a down payment, trade-in, or manufacturer rebates.

The Math Behind the Lease

The monthly payment consists of three main parts:

1. Depreciation: (Net Capitalized Cost – Residual Value) / Lease Term.
2. Rent Charge: (Net Capitalized Cost + Residual Value) * Money Factor.
3. Sales Tax: Calculated on the sum of the depreciation and rent charge in most states.

Calculation Example

Imagine a car with an MSRP of $40,000 and a negotiated price of $38,000. You put $3,000 down, leaving a net capitalized cost of $35,000. If the residual value is 60% ($24,000) for a 36-month term and the money factor is 0.0015:

• Depreciation: ($35,000 – $24,000) / 36 = $305.56
• Rent Charge: ($35,000 + $24,000) * 0.0015 = $88.50
• Base Payment: $305.56 + $88.50 = $394.06
