Auto Lease Calculator

Lease payments consist of two components: a depreciation charge and a finance charge. The depreciation charge covers the difference between the vehicle's capitalized cost and its residual value at the end of the lease, divided by the number of months. The finance charge is based on the money factor, which is roughly the annual interest rate divided by 2,400. Sales tax is then applied to the sum of these two charges, though some states tax the full vehicle price instead of just the monthly payment.

The money factor is a decimal number used in lease calculations that represents the financing cost. To convert a money factor to an equivalent APR, multiply it by 2,400. For example, a money factor of 0.00125 equals a 3% APR, while 0.00250 equals 6% APR. When comparing lease offers, always convert the money factor to APR so you can compare it directly with traditional loan interest rates and evaluate whether the financing cost is competitive.

Leasing offers lower monthly payments and the ability to drive a new car every few years, but you build no equity and face mileage restrictions typically capped at 10,000 to 15,000 miles per year. Buying costs more monthly but gives you full ownership once the loan is paid off. Financially, buying and holding a vehicle for 8-10 years is usually cheaper in the long run, while leasing can make sense if you value always having the latest safety features and want predictable maintenance costs under warranty.

Focus on negotiating the capitalized cost (selling price) of the vehicle, as this directly reduces both your depreciation charge and finance charge. Research the money factor for your credit tier through online lease forums before visiting the dealer. Ask about manufacturer lease incentives and loyalty bonuses that can lower your effective cost. Avoid large down payments on leases because if the vehicle is totaled or stolen, gap insurance covers the lease balance but you lose your down payment entirely.
