How to Use the Car Lease Calculator

Leasing a vehicle can be more complex than a traditional auto loan because you aren't paying for the entire car—only the portion you "use" during the lease term. Our car lease calculator helps you break down the math to ensure you're getting a fair deal from the dealership.

Key Components of a Lease Calculation

  • Gross Capitalized Cost: This is the negotiated price of the vehicle plus any additional fees or taxes rolled into the lease.
  • Residual Value: This is the estimated value of the car at the end of the lease. It is usually set by the manufacturer and expressed as a percentage of the MSRP.
  • Money Factor: This is essentially the interest rate on a lease. To convert a money factor to an APR, multiply it by 2400. (e.g., 0.00125 x 2400 = 3% APR).
  • Capitalized Cost Reduction: This includes your down payment, trade-in credit, and any manufacturer rebates that reduce the amount you need to lease.

The Math Behind Your Payment

Your monthly payment consists of two primary parts: Depreciation and the Rent Charge.

1. Depreciation: (Adjusted Cap Cost – Residual Value) / Number of Months. This covers the value the car loses while you drive it.

2. Rent Charge: (Adjusted Cap Cost + Residual Value) × Money Factor. This is the fee paid to the leasing company for using their capital.

Realistic Example

Imagine you are leasing a car with an MSRP of $40,000. You negotiate the price down to $37,000 and put $3,000 down. The 36-month residual is 60% ($24,000), and the money factor is 0.0015.

  • Cap Cost: $37,000 – $3,000 = $34,000
  • Depreciation: ($34,000 – $24,000) / 36 = $277.78/mo
  • Rent Charge: ($34,000 + $24,000) * 0.0015 = $87.00/mo
  • Total Payment: $364.78/month (plus taxes)
