Understanding Auto Leases

Leasing a vehicle differs significantly from purchasing. When you lease, you're essentially paying for the vehicle's depreciation during your lease term plus finance charges, rather than the entire value of the vehicle.

Key Lease Terms
  • MSRP (Manufacturer's Suggested Retail Price): The sticker price of the vehicle.
  • Negotiated Price: The agreed-upon price after negotiation, which affects your lease payment.
  • Residual Value: The estimated value of the vehicle at the end of the lease. Higher residual value typically means lower monthly payments.
  • Money Factor: Similar to an interest rate. To convert to APR, multiply by 2400.
  • Capitalized Cost: The amount being financed in the lease, which includes the negotiated vehicle price plus fees, minus down payment and incentives.
Lease vs. Buy Considerations
  • Lower Payments: Lease payments are typically lower than loan payments for the same vehicle.
  • Mileage Limits: Leases include mileage restrictions with excess mileage fees.
  • No Equity: At the end of a lease, you don't own the vehicle unless you choose to purchase it.
  • Latest Features: Leasing allows you to drive a new vehicle with the latest technology every few years.
  • Wear and Tear: You may be charged for excessive wear and tear at lease end.
Tips for Better Lease Deals
  • Negotiate the vehicle's selling price, not just the monthly payment.
  • Understand the money factor and try to negotiate it if possible.
  • Consider the residual value - higher is typically better for lessee.
  • Be realistic about your driving habits when selecting mileage allowance.
  • Minimize your down payment, as it's at risk if the vehicle is totaled early in the lease.
