Car Lease Calculator

A car lease payment is fundamentally built on two main components: depreciation and finance charges (often referred to as rent charges), plus applicable local taxes. First, the Capitalized Cost is determined by taking the negotiated vehicle price, adding dealer and registration fees, and subtracting any down payments, trade-in values, or manufacturer rebates. The Residual Value represents the estimated worth of the vehicle at the end of the lease term, calculated by multiplying the MSRP by the residual factor. The monthly depreciation is then found by dividing the difference between the capitalized cost and residual value by the lease term in months. Finally, the finance charge is computed using the money factor multiplied by the sum of the capitalized cost and residual value.

Imagine you are leasing a car with an MSRP of $35,000, and you negotiate the price down to $33,000. Dealer and registration fees total $1,000. You make a down payment of $2,000 and have a trade-in valued at $3,000. Your negotiated discount (negotiation deduction) is $2,000 ($35,000 minus $33,000). Your Capitalized Cost becomes ($33,000 + $1,000) - ($2,000 + $3,000) = $29,000. Assuming a 36-month lease term and a 55% residual factor, the Residual Value is $35,000 * 0.55 = $19,250. The monthly Depreciation Value is ($29,000 - $19,250) / 36 = $270.83. If your money factor generates a monthly interest charge of $75, your pre-tax monthly payment is $345.83. Adding a 7% sales tax on that total brings your final monthly payment to approximately $370.04.

Always negotiate the capitalized cost (the actual purchase price of the vehicle) before discussing monthly payments with a dealer. Dealerships can easily manipulate monthly payments by stretching out the lease term or hiding fees if you do not focus on the vehicle's true selling price. Additionally, pay close attention to the money factor; multiplying it by 2,400 will give you a rough estimate of the equivalent annual percentage rate (APR) so you can compare it against traditional auto loan rates.
