Defining a Car Lease
A car lease is a contractual agreement between a driver and a leasing company (often the financing arm of an automaker) that grants you the right to drive a vehicle for a fixed term — usually 24 to 36 months — in exchange for monthly payments.
Unlike a traditional purchase loan where payments cover the vehicle's full price, lease payments cover only the expected depreciation during your drive period plus finance charges (money factor). Compare lease vs buyout costs using AutoLoanIQ's free lease payoff calculator.
The Three Key Pillars of Lease Accounting
| Lease Term | Simple Explanation | How It Affects Your Payment |
|---|---|---|
| Gross Capitalized Cost | The agreed-upon sales price of the vehicle plus fees. | Higher cap cost increases your monthly payment. |
| Residual Value | The estimated cash value of the car when the lease ends. | Higher residual value lowers your monthly payment! |
| Money Factor (Rent Charge) | The annual interest rate written as a small decimal. | Multiply by 2,400 to convert to standard APR. |
For example, a money factor of `0.00250` equals a `6.0%` APR (`0.00250 × 2,400 = 6.0%`).
How Monthly Lease Payments Are Calculated
A monthly lease payment consists of two core components:
- Depreciation Fee: `(Adjusted Cap Cost − Residual Value) ÷ Lease Term`
- Finance (Rent) Fee: `(Adjusted Cap Cost + Residual Value) × Money Factor`
