How does a car lease work? Every step, in order
How does a car lease work? You pay to use a new car for a set number of months and miles, covering the value the car loses in that time, a rent charge for the lender's money, and tax and fees.

Key takeaways
The leasing company owns the car, and when the lease ends you return it, buy it at a price fixed on the day you signed, or sell or trade it if it's worth more than that price. In California, sales tax is charged on each monthly payment rather than on the car's full price.
Three parties are involved. The dealer supplies the car and usually signs the lease with you, then assigns it to a lender, often the carmaker's own finance company, which becomes your lessor. You are the lessee: you drive the car, insure it, maintain it and make the payments to the lender.
How does a car lease work, step by step?
Choose the car and agree on its price. The agreed price is the starting point of the capitalized cost, the number the whole lease is built on. It's negotiable, just like a purchase price, and it's where most of the savings are.
Pick a term and a mileage allowance. A typical lease runs two to four years, and most allow 10,000 to 15,000 miles a year. Both change the payment. See choosing a lease term and choosing your lease mileage.
The lender sets the residual value and the money factor. The residual value is the lender's estimate of the car's worth at the end of your term. The money factor sets the rent charge, the lease's version of interest, and depends on your credit.
The payment is calculated. You pay the drop in value spread across the term, plus the rent charge, plus tax. The math is shown below.
Decide what to pay upfront. The amount due at signing usually covers the first payment, fees and taxes, and sometimes a down payment.
The lender approves your credit. Approval, and the money factor you're offered, are the lender's decision.
Sign the lease contract. Federal and California law set out what it must show. Read all of it first: California has no cooling-off period on a new-car lease.
Register and insure the car. The leasing company is listed as the owner and you as the lessee, and you carry the insurance the lease requires.
Drive, maintain and pay. Service the car on the manufacturer's schedule, keep the records and watch your miles.
End the lease. Return the car, buy it, sell or trade it, or extend. Ending early is possible but usually costly.
The numbers that set your lease payment
Capitalized cost. The agreed price of the car plus anything added to the lease, such as the acquisition fee, a service contract or a balance from your trade-in, minus any cap cost reduction (cash down, rebates or trade-in credit). Lower is better, and this is the number you negotiate.
Residual value. Set by the lender, usually as a percentage of the car's MSRP for your term and mileage. A higher residual leaves less value loss to pay for. You generally can't negotiate it.
Money factor. A small decimal that sets the rent charge. Multiply it by 2,400 for a rough annual interest rate. The one on a quote can be above the lender's base rate for your credit, so ask.
Term. The number of monthly payments.
Mileage allowance. Fewer miles mean a higher residual and a lower payment, but every mile over the allowance is charged at the end. See over your lease miles.
How the monthly payment is calculated
Most lenders build the payment the same way, and your contract shows each piece. Before tax, the payment has two parts:
Depreciation charge: the capitalized cost minus the residual value, divided by the number of months.
Rent charge: the capitalized cost plus the residual value, multiplied by the money factor.
Add the two for the base payment, then add sales tax at the rate for the address where the car will be registered.
Example (made-up round numbers): a car with an MSRP of $50,000 and a capitalized cost of $50,000, a 60% residual ($30,000), 36 months and a money factor of 0.00200. The tax rate is a round 10% to keep the math easy; yours depends on your address.
Depreciation charge: $50,000 minus $30,000 is $20,000, and $20,000 divided by 36 months is $555.56.
Rent charge: $50,000 plus $30,000 is $80,000, and $80,000 times 0.00200 is $160.00.
Base payment: $555.56 plus $160.00 is $715.56.
Tax at the example rate: $71.56, for a total of $787.11 a month.
In this example, the money factor of 0.00200 is roughly a 4.8% annual rate (0.00200 times 2,400). Over 36 months you'd pay $20,000 for the car's loss in value and $5,760 in rent charges, before tax.
To check a real quote, get the dealer's capitalized cost, residual, money factor and term in writing and run the same steps. If your result is well below the quoted payment, the capitalized cost includes something you didn't expect or the money factor is higher than you were told.

What you pay at signing
The amount due at signing, often called the drive-off, is usually the first monthly payment plus fees and taxes. A "zero down" lease normally means no cap cost reduction, not nothing due. Putting a lot of money down lowers the payment, but you save only the rent charge on that money, and you don't get it back if the car is stolen or totaled. Details in due at signing and "zero down".
How does a car lease work in California?
Tax is charged payment by payment. California taxes each monthly payment, plus taxable amounts at signing such as a cash down payment, trade-in credit applied to the lease and dealer fees. The rate is the statewide 7.25% plus any district taxes for the address where the car is registered. See California sales tax on a car lease.
The dealer's document fee has a legal cap: $85 for dealers that handle DMV registration electronically as private industry partners, $70 for other dealers. It can't be presented as a government fee. See car lease fees explained.
The contract must itemize the capitalized cost. California requires a separate, boxed Itemization of Gross Capitalized Cost that lists the agreed value of the car and each item added to it, such as service contracts, insurance, optional debt cancellation (GAP) coverage and any balance carried over from a trade-in.
There's no cooling-off period on a new-car lease. Once you sign, you can cancel only if the lessor agrees or for legal cause such as fraud. The CARS Act adds a three-day right to cancel from October 1, 2026, but only for some used vehicles.
If the lender doesn't approve your credit, the contract must tell you that you can return the car and get back what you paid, unless the refusal came from an incomplete application or incorrect information you gave.
Payment quotes must show the total. From October 1, 2026, a dealer that quotes you a monthly payment in writing must also show the total you'll pay over the lease and any down payment or trade-in that payment assumes.
What the lease contract shows
Federal Regulation M requires a standard set of disclosures on consumer leases, and California requires the same disclosures on every personal vehicle lease longer than four months, whether or not the federal rule applies. Look for:
the amount due at signing, itemized;
the monthly payment and how it was calculated: gross capitalized cost, cap cost reduction, adjusted capitalized cost, residual value, depreciation and rent charge;
the total of payments;
a warning that ending the lease early can cost a substantial amount, possibly several thousand dollars;
your responsibility for excess wear and mileage;
whether you can buy the car and at what price.
The money factor doesn't have to appear, and often doesn't. You can work it out from the contract: divide the total rent charge by the number of payments, then divide the result by the adjusted capitalized cost plus the residual value.
Living with a leased car
Registration. The registration card lists the leasing company as owner and you as lessee. Depending on the address the lessor chose, the DMV renewal notice comes to you or to the lessor, which then bills you. Renewals include the vehicle license fee, 0.65% of the car's value each year.
Insurance. You must keep coverage that meets the leasing company's standards, not just California's legal minimum. Some leases include GAP coverage; see GAP and insurance on a leased car.
Maintenance. Service the car on the manufacturer's schedule and keep the records. Wear beyond the lender's normal-use standards is charged at turn-in; see excess wear and tear.
Miles. Compare your odometer with the allowance every few months. You have more options when you spot an overage early.
Moving. Update your address with the leasing company and the DMV. The tax on your payments is based on where the car is registered.
How a car lease ends
Return it. Ask about a pre-return inspection, turn the car in, and pay any excess wear, excess mileage and disposition fee in your contract. See returning a leased car and the disposition fee.
Buy it. The purchase option price is in your contract and is based on the residual value, sometimes plus a purchase option fee. California taxes the buyout as a sale. See buying out your lease.
Sell or trade it. If the car is worth more than the buyout price, the difference is your lease equity. Whether a dealer or buying service can buy the car directly depends on your lender's current rules; see third-party lease buyouts.
Extend it, month to month or for a fixed period, if your lender allows. See extending your car lease.
You can also end a lease early, or transfer it where the lender permits. Early termination usually costs a lot. California law limits what the lessor can charge and requires it to act in a commercially reasonable way when it sells the car. Start with every lease-end option and getting out of a car lease early.
Lease or buy?
Leasing suits drivers who want a new car every two to four years, drive a predictable number of miles and want to stay within the factory warranty. Buying usually costs less if you drive a lot or keep cars for many years. California adds a tax angle: a purchase is taxed on the full price and a trade-in doesn't reduce that, while a lease is taxed only on what you pay. The side-by-side math is in lease vs buy a car.
Before you sign
Get the capitalized cost, the residual (percentage and dollar amount), the money factor, the term, the mileage and the total due at signing in writing.
Ask whether the money factor is the lender's base rate for your credit tier. More in how to negotiate a car lease.
Read the Itemization of Gross Capitalized Cost line by line and question anything you didn't ask for; see dealer add-ons and junk fees.
Check the tax rate for your registration address on CDTFA's rate lookup.
Confirm whether GAP coverage is included.
