Car Lease Payment Formula
Unlike a loan where you finance the full purchase price, a lease payment covers only the vehicle's depreciation during the lease term plus a finance charge on the full value.
Money Factor vs APR

How Car Lease Payments Are Calculated Methodology.
The Calculation Branch
Industrial Standards.
Money factor is the lease equivalent of an interest rate. Multiply money factor by 2400 to get approximate APR. The finance charge is calculated on the sum of the capitalized cost and residual value (not just the cap cost) because the lender has capital tied up in the vehicle for the full duration of the lease.
In-Depth Analysis & Reference Data
To negotiate the best lease: focus on cap cost reduction (negotiate the sale price as if you're buying), verify the money factor matches the manufacturer's published base rate (not a dealer markup), and check the residual value (it's set by the manufacturer and is not negotiable). A $500 cap cost reduction saves you $500 ÷ 36 = $13.89/month on a 36-month lease. A money factor increase of 0.0001 (equivalent to 0.24% APR) on a $35,000 vehicle costs an extra ~$7/month.
Registry Questions & FAQ.
Is it smart to put money down on a lease?
Financial experts generally advise against large down payments (cap cost reductions) on leases. If your leased car is totaled in an accident, the insurance pays the residual value to the leasing company — you lose your down payment entirely. Instead of a down payment, make a higher monthly payment or negotiate a lower cap cost. Drive-off fees (first month, registration, documentation) are unavoidable but keep additional cap cost reductions minimal.
What happens at the end of a car lease?
At lease end you have three options: return the car (pay any excess mileage or wear charges), buy the car at the residual price, or trade it in on a new lease. If used car prices are high, buying your leased car at the contracted residual and reselling it can sometimes yield a profit. If used prices are low, returning it is usually the best choice.
