Understanding Your Car Lease Calculation

Calculating a car lease is more complex than a standard auto loan. While a loan pays off the entire vehicle value plus interest, a lease only pays for the portion of the car's value you "consume" during the term, plus a financing fee known as the money factor.

Key Leasing Terms Explained

  • Gross Capitalized Cost: The negotiated price of the vehicle (MSRP plus any add-ons).
  • Residual Value: The predicted value of the car at the end of the lease term. This is set by the leasing company and expressed as a percentage of the MSRP.
  • Money Factor: The interest rate of the lease. To convert a standard APR to a money factor, divide by 2400. For example, a 3% APR is a 0.00125 money factor.
  • Depreciation Fee: Calculated as (Net Cap Cost – Residual Value) / Lease Term.
  • Rent Charge: Calculated as (Net Cap Cost + Residual Value) × Money Factor. This is effectively the interest you pay on the capital tied up in the car.

Example Lease Scenario

If you lease a car with an MSRP of $40,000, a 60% residual value after 36 months, and a down payment of $2,000:

  • Cap Cost: $38,000 ($40,000 MSRP – $2,000 Down)
  • Residual Value: $24,000 (60% of $40,000)
  • Total Depreciation: $14,000 over 3 years
  • Monthly Depreciation: $388.89
  • Money Factor: 0.0015 (approx. 3.6% APR)
  • Monthly Rent: ($38,000 + $24,000) * 0.0015 = $93.00
  • Total Monthly Base Payment: $481.89
