How a Car Lease Payment is Actually Calculated
Unlike a traditional auto loan, a car lease doesn't just divide a loan amount by a set of months. Instead, you are paying for the depreciation of the vehicle during the time you drive it, plus a financing fee known as the Money Factor .
Key Components of Your Lease Math
Negotiated Selling Price: This is the price you agree to pay for the car before any incentives or trade-ins. It is often referred to as the Gross Capitalized Cost.Capitalized Cost Reduction: This is any amount that reduces the "loan" balance at the start. It includes your cash contribution, trade-in equity, and manufacturer rebates.Residual Value: This is the bank's estimate of what the car will be worth at the end of the lease. It is calculated as a percentage of the MSRP (not the selling price).Money Factor: This represents the interest rate. To convert a Money Factor to a standard APR, multiply it by 2400. For example, a money factor of 0.00125 equals a 3% APR.
The Three-Part Formula
Your total monthly payment consists of three distinct parts:
1. Depreciation Fee: (Net Capitalized Cost – Residual Value) / Lease Term
2. Rent Charge (Financing): (Net Capitalized Cost + Residual Value) × Money Factor
3. Sales Tax: (Depreciation Fee + Rent Charge) × Local Tax Rate
Example Calculation
Imagine a vehicle with an MSRP of $50,000 and a negotiated price of $47,000. You put $2,000 down (Cap Cost Reduction). The term is 36 months, the residual is 60%, and the money factor is 0.0015.
Residual Value: $50,000 × 0.60 = $30,000Net Cap Cost: $47,000 – $2,000 = $45,000Depreciation Fee: ($45,000 – $30,000) / 36 = $416.67Rent Charge: ($45,000 + $30,000) × 0.0015 = $112.50Total Base Payment: $529.17 + Sales Tax
