Formula: Monthly = (Net Cap Cost - Residual) / Term + (Net Cap Cost + Residual) x Money Factor
Worked example — Monthly Payment: $483.65 | Total Cost: $19,411
Formula
Monthly = (Net Cap Cost - Residual) / Term + (Net Cap Cost + Residual) x Money Factor
The first part is the depreciation charge (how much value the car loses during the lease). The second part is the finance charge (interest cost). Add sales tax to get the final monthly payment.
Worked Examples
Example 1: Standard 36-Month Sedan Lease
Problem:MSRP $35,000, negotiated price $33,000, $2,000 down, 55% residual, money factor 0.0025, 36 months, 7% tax.
Solution:Residual value = $35,000 x 55% = $19,250 Net cap cost = $33,000 - $2,000 = $31,000 Depreciation = ($31,000 - $19,250) / 36 = $326.39/mo Finance charge = ($31,000 + $19,250) x 0.0025 = $125.63/mo Pre-tax payment = $326.39 + $125.63 = $452.01 Tax = $452.01 x 7% = $31.64 Monthly payment = $483.65
Result:Monthly Payment: $483.65 | Total Cost: $19,411
Example 2: Luxury SUV 24-Month Lease
Problem:MSRP $55,000, negotiated $52,000, $3,000 down, 60% residual, money factor 0.0015, 24 months, 6% tax.
Solution:Residual = $55,000 x 60% = $33,000 Net cap cost = $52,000 - $3,000 = $49,000 Depreciation = ($49,000 - $33,000) / 24 = $666.67/mo Finance = ($49,000 + $33,000) x 0.0015 = $123.00/mo Pre-tax = $789.67 Tax = $789.67 x 6% = $47.38 Monthly = $837.05
Result:Monthly Payment: $837.05 | Total Cost: $23,089
Frequently Asked Questions
How is a car lease payment calculated?
A car lease payment consists of two main components: depreciation and a finance charge. The depreciation portion equals the net capitalized cost minus the residual value, divided by the number of months in the lease term. The finance charge equals the sum of the net capitalized cost and the residual value, multiplied by the money factor. These two components are added together to get the pre-tax monthly payment. Sales tax is then applied to this amount based on your state rate. The net capitalized cost is the negotiated vehicle price minus any down payment, trade-in value, or rebates. Understanding this formula helps you identify exactly where your money goes each month.
What is a money factor and how does it relate to APR?
The money factor is a decimal number used by leasing companies to calculate the finance charge portion of your lease payment. It functions similarly to an interest rate but is expressed differently. To convert a money factor to an equivalent APR (Annual Percentage Rate), multiply it by 2,400. For example, a money factor of 0.0025 equals an APR of 6.0% (0.0025 x 2,400). A lower money factor means lower financing costs. Good credit scores typically qualify for money factors around 0.0010 to 0.0020 (2.4% to 4.8% APR). The money factor is not always disclosed upfront, so you may need to ask the dealer specifically for this number.
What is residual value and why does it matter for leasing?
Residual value is the estimated worth of the vehicle at the end of the lease term, expressed as a percentage of the original MSRP. It is set by the leasing company and is not negotiable. A higher residual value means less depreciation during the lease, which directly lowers your monthly payment. For example, a $35,000 car with a 55% residual retains $19,250 in value, so you only pay for $15,750 in depreciation over the lease. Vehicles with strong resale value like Honda, Toyota, and Lexus typically have higher residuals, making them cheaper to lease relative to their price. The residual also determines your purchase option price if you decide to buy the car at lease end.
Should I put a down payment on a lease?
Most financial experts advise against large down payments on a car lease. While a down payment reduces your monthly payment, it increases your financial risk. If the car is totaled or stolen shortly after leasing, the insurance payout goes to the leasing company, and you lose your down payment entirely. Gap insurance covers the difference between the car value and what you owe on the lease, but it does not reimburse your cash down payment. A better strategy is to negotiate a lower selling price or find a lease with a lower money factor. If you must reduce monthly payments, consider a shorter-term lease or a vehicle with a higher residual percentage.
How can I negotiate a better car lease deal?
Focus on negotiating the capitalized cost (selling price), which directly reduces your payments. Research the invoice price and negotiate as if you were buying the car outright. Check multiple dealers for competing offers and lease incentives. Look for manufacturer lease specials with subvented (subsidized) money factors and boosted residuals. Time your lease near quarter-end or year-end when dealers are motivated to move inventory. Ask for the money factor in writing so you can verify it is competitive. Reduce fees by questioning the acquisition fee, disposition fee, and any dealer-added accessories. Also verify that the mileage allowance matches your driving habits because excess mileage charges of 15 to 25 cents per mile add up quickly at lease return.
What is the difference between gross capitalized cost and net capitalized cost?
Gross capitalized cost is the agreed vehicle price plus anything rolled into the lease — acquisition fee, extended warranty, dealer add-ons or negative equity from a trade-in. Net capitalized cost is that figure minus capitalized cost reductions: your cash down payment, trade-in equity and any manufacturer rebate. Only the net figure feeds the payment formula, so it is the number to check on the lease worksheet. Watch for fees quietly capitalized into the gross cost, because each dollar added raises both the depreciation charge and the finance charge.
How does the mileage allowance interact with the residual value?
The residual percentage the leasing company quotes assumes a specific annual mileage allowance. Choosing a higher allowance means the vehicle is expected to be worth less at turn-in, so the residual is reduced and the depreciation portion of every payment rises. Buying extra miles upfront is normally cheaper per mile than paying the excess-mileage charge at lease end, but unused prepaid miles are typically not refunded. Estimate your true annual driving before signing, since the allowance is fixed for the whole term.
Which fees appear in a lease that do not appear in a purchase?
Two are unique to leasing. The acquisition or bank fee is charged by the leasing company at inception to originate the contract, and it may be paid upfront or capitalized. The disposition fee is charged at turn-in to cover reconditioning and resale of the returned vehicle, and it is usually waived if you buy the car or lease another from the same brand. On top of these you still pay registration, documentation and any first-month payment due at signing, so drive-off cost is always higher than one monthly payment.
Why is ending a lease early usually expensive?
A lease is a fixed-term contract, so early termination generally requires paying the remaining payments or an early-termination charge based on the difference between the vehicle's current market value and the contract's adjusted lease balance. Because depreciation is front-loaded on most vehicles while lease payments are level, the balance owed early in the term often exceeds what the car is worth. A lease transfer or assumption, where permitted by the leasing company, is usually cheaper than terminating outright.
When does buying the car at lease end make financial sense?
The purchase option price is set by the residual value written into the contract, fixed at signing. If used-car values rise during the term, the market value can exceed that fixed residual, and exercising the buyout captures the difference — you buy an asset for less than it is worth. If market value sits below the residual, returning the vehicle and letting the leasing company absorb the shortfall is the better choice. Compare a current valuation against the contract residual plus any purchase fee and sales tax before deciding.
