Car Lease Calculator
The manufacturer's suggested retail price shown on the window sticker.
The agreed price before fees and incentives. Negotiating this down has the biggest impact on your payment.
Percentage of MSRP the vehicle is worth at lease end. Set by the manufacturer. Typical range: 45–62% for 36-month leases.
APR equivalent: 4.200%

How to Use the Car Lease Calculator
Enter the Vehicle Prices
Input the MSRP from the window sticker and the negotiated selling price you have agreed upon with the dealer. If you have not yet negotiated, start with the MSRP and experiment with lower values to see the payment impact. Negotiating the cap cost down is the most powerful way to reduce your monthly payment.
Set Term, Residual Value, and Money Factor
Select your lease term (36 months is most popular). Enter the residual value percentage — ask your dealer or check the manufacturer's website for the current residual. Enter the money factor (also ask the dealer for the buy rate MF) or switch to APR mode and enter the equivalent interest rate. Use the credit tier preset buttons as a quick benchmark for your credit score range.
Add Fees and Incentives
Expand Advanced Options to enter the acquisition fee (usually $595–$1,095, non-negotiable), registration fees, any manufacturer rebates, and your security deposit. If you have a trade-in, enter both its value and any remaining loan payoff balance. These numbers all affect your net capitalized cost and the total cash due at signing.
Review Your Deal Quality and Total Cost
Check the Deal Quality Score — a monthly payment under 1% of MSRP is a good deal, under 0.8% is exceptional. Review the total lease cost and effective cost per mile to compare this deal against alternatives. Export your results to CSV or print them to bring to the dealership as a reference during negotiations.
Frequently Asked Questions
What is a money factor and how does it relate to APR?
The money factor is the leasing equivalent of an interest rate, expressed as a small decimal (e.g., 0.00175). To convert it to an equivalent APR, multiply by 2,400: a money factor of 0.00175 equals a 4.2% APR. Dealers are not always upfront about the money factor, but you have the right to ask for it. Comparing the quoted money factor to your credit tier's expected rate helps you verify whether the dealer has added a mark-up. Most manufacturers allow dealers to mark up the money factor by up to 0.00050, which can add $15–$30 to your monthly payment on a $30,000 vehicle.
Why is the residual value so important in a lease?
The residual value determines how much of the vehicle's value you depreciate over the lease term — and depreciation is the largest component of your monthly payment. A higher residual means you finance less depreciation, resulting in a lower monthly payment. For example, on a $35,000 vehicle with a 36-month lease, going from a 45% to a 55% residual reduces your monthly depreciation by roughly $97/month. Residuals are set by the manufacturer's captive finance arm and are not negotiable, but they vary by vehicle, lease term, and mileage allowance. Vehicles with strong resale value (SUVs, certain luxury brands, hybrids) tend to have the most favorable residuals.
What is the 1% rule for lease deals?
The 1% rule is a quick rule of thumb used by savvy lessees to evaluate deal quality: if your monthly payment is less than 1% of the vehicle's MSRP, it is generally a good deal. For example, a $350/month payment on a $35,000 car (1.0%) is average, while $280/month (0.8%) would be an excellent deal. Our calculator displays your deal score automatically as a percentage of MSRP and categorizes it from Exceptional (below 0.8%) to Poor (above 1.5%). Keep in mind this is a rough benchmark — market conditions, location, and specific vehicle demand all affect what deals are actually achievable.
What is the net capitalized cost?
The net capitalized cost (or adjusted cap cost) is the effective vehicle price that the lease payment is calculated on. It starts with your negotiated selling price, then adds the acquisition fee and registration fees, and subtracts your down payment, trade-in equity, and manufacturer rebates. This is the most important number to negotiate — reducing the cap cost by $1,000 reduces your monthly depreciation by roughly $27–$42/month depending on lease term. Always negotiate the selling price as if you were buying the car, not leasing it, since the same discount applies in either case.
Should I put money down on a lease?
Financially speaking, making a large down payment on a lease is generally not recommended. Unlike a car purchase, where a down payment builds equity, a down payment on a lease simply reduces your monthly payment for the duration — you get no return on that money at lease end. More importantly, if the vehicle is totaled or stolen in the first few months, your insurance payout goes to the lender, and you may lose your down payment entirely. A safer approach is to keep the down payment minimal and put that money in a savings account. The monthly payment reduction from a $3,000 down payment on a 36-month lease is only about $83/month — not always worth the risk.
What fees are due at signing for a car lease?
Cash due at signing typically includes: (1) your down payment or cap cost reduction, (2) the first month's payment, (3) a refundable security deposit (sometimes waived), (4) acquisition fee if not rolled into the cap cost, and (5) registration, title, and documentation fees. Some dealers offer sign-and-drive deals where these upfront costs are rolled into the monthly payment (a higher cap cost), resulting in zero due at signing. This sounds attractive but means you pay interest on those fees for the entire lease term. Our calculator helps you see the trade-off between upfront costs and monthly payment.
