How to interpret the result
A lease payment is built from two genuinely separate pieces, a depreciation charge covering the vehicle's expected value loss and a finance charge functioning like interest on the money factor, and understanding which piece is driving a specific payment reveals what's actually negotiable, since the two respond to different levers.
Before you rely on it
What to check
Break the quoted payment into its depreciation and finance components separately, since negotiating the capitalized cost affects one component while the money factor affects the other.
The common error
Where people go wrong with auto lease calculator
Treating a lease payment as one undifferentiated number without separating the depreciation and finance charge components. Negotiating the price affects one piece; negotiating the money factor affects the other, and conflating them means missing where the real negotiating leverage actually sits.

Where the inputs come from
Negotiated vehicle price is the capitalized cost you agreed on, which you can negotiate as you would a purchase price. Capitalized-cost reduction is what you pay up front, such as a down payment or trade-in credit, residual value is what the lessor expects the car to be worth at the end, set by the lessor, and lease term is in months. The money factor is the finance charge, and multiplying it by 2400 gives an approximate APR. Sales tax applies to the payment in many states.
Using the estimated monthly lease payment in a real decision
Compare the total of payments with the alternative of buying.
When the result stops applying
Leases add fees such as acquisition, disposition and excess wear, and mileage limits apply. Down payments on a lease can be lost if the car is totaled early. Tax treatment differs by state: some tax the whole price and some the payments. A lease ends with no ownership unless you buy the car at the residual. Advertised payments often assume high down payments.
What to compare it with
Convert the money factor with the lease money factor calculator, and estimate mileage charges on the lease mileage page. The lease versus buy calculator compares the total cost of the two, and the auto loan calculator gives the purchase alternative. Ask the dealer for the money factor and residual in writing.

Frequently asked questions
What is a money factor?
The lease finance charge, expressed as a small decimal. Multiply by 2400 to get an approximate annual percentage rate.
Can I negotiate a lease?
Yes. The vehicle price, the money factor, fees and sometimes the mileage allowance are negotiable, while the residual value is set by the lessor.
Is a big down payment on a lease a good idea?
Usually not. If the car is stolen or totaled early, the down payment is generally lost, so many people prefer to keep the up-front cost low.
