How to Use the Car Lease Calculator
Leasing a car can be more complex than buying one because the payment isn't just based on the price, but on how much value the car loses over time. This calculator helps you break down the monthly costs so you can negotiate a better deal at the dealership.
Understanding Key Leasing Terms
Gross Capitalized Cost: The negotiated price of the vehicle plus any added fees like acquisition or documentation fees.
Residual Value: This is what the leasing company estimates the car will be worth at the end of your lease. It is usually expressed as a percentage of the MSRP.
Money Factor: This is essentially the interest rate on a lease. To convert a money factor to a standard APR, multiply it by 2400 (e.g., 0.0025 * 2400 = 6% APR).
Depreciation Fee: The portion of your payment that covers the car's loss in value.
The Car Lease Formula
The monthly payment is calculated by adding the Depreciation Fee and the Rent Charge (interest), then applying the Sales Tax .
1. Monthly Depreciation = (Net Cap Cost – Residual Value) / Lease Term
2. Monthly Rent Charge = (Net Cap Cost + Residual Value) × Money Factor
3. Total Monthly Payment = (Depreciation + Rent Charge) × (1 + Tax Rate)
Example Calculation
Imagine you are leasing a $40,000 SUV for 36 months . The dealer offers a 60% residual value ($24,000) and a money factor of 0.002 . You put $2,000 down .
Net Cap Cost: $40,000 – $2,000 = $38,000
Depreciation: ($38,000 – $24,000) / 36 = $388.89
Rent Charge: ($38,000 + $24,000) * 0.002 = $124.00
Pre-tax Total: $512.89
With a 7% tax rate, your final monthly payment would be approximately $548.79 .
