Introduction
A car lease can be hard to understand. The monthly payment depends on many things, like the selling price, residual value, money factor, fees, and taxes. Most people never see how these numbers work together, which makes it easy to miss a bad deal.
This free lease calculator breaks down every part of your car lease payment so you know exactly what you are paying and why. Enter your vehicle price, lease term, money factor, and fees to get a full summary. You will see your monthly payment, total cost, due-at-signing amount, and a deal score that tells you if the offer is good or not.
The calculator also shows a step-by-step solution, a side-by-side lease vs. finance comparison using our auto loan calculator logic, and sensitivity tables so you can see how small changes to the residual or money factor affect your payment. This tool helps you make a smart choice with clear numbers instead of guesswork.
How to Use Our Lease Calculator
Enter your vehicle and deal details below to calculate your monthly lease payment, total cost, due-at-signing amount, and overall deal score. The calculator will also show you a full cost breakdown, step-by-step math, and comparison charts.
Vehicle & Deal Basics
MSRP (Sticker Price): Enter the full manufacturer's suggested retail price of the vehicle. You can find this on the window sticker.
Selling Price: Enter the price you and the dealer agreed on. This is often lower than the MSRP.
% Off MSRP: This shows how much of a discount you are getting. It updates automatically when you change the selling price, or you can type a percentage here to set the selling price.
Vehicle Make: Pick the car brand from the list. For some brands, this fills in the leasing company's acquisition fee and disposition fee. You can change either one.
Pre-Existing Demo/Loaner Miles: If the car was used as a demo or loaner, enter the miles already on it. Leave this at 0 for a new vehicle.
Residual Reduction per Demo Mile: Enter the amount per mile your leasing company takes off the residual value for miles already on the car. The calculator multiplies it by the demo miles and subtracts the result from the residual value.
Lease Terms
Lease Term: Pick how many months your lease will last, from 24 to 48.
Annual Mileage Allowance: Choose the number of miles per year included in your lease. In the case of a higher mileage limit, the residual value is reduced to reflect the higher mileage.2 Enter the residual value your leasing company quotes for the allowance you choose. If you drive more than the allowance, you may owe overage fees.
Residual Value (% of MSRP): Enter the residual value as a percentage of MSRP. This is what the car is expected to be worth at lease end. Your dealer or leasing company provides this number.
Estimated Actual Annual Miles: Enter how many miles you think you will really drive each year. If this is more than your allowance, the calculator will estimate your overage cost.
Overage Rate per Mile: Enter the cost per mile you will be charged for going over your mileage allowance. Your lease disclosures must state the amount or method for working out any charge for excess mileage.7 Lexus lease offers, for example, charge $0.25 per mile for all mileage over 10,000 miles per year.8
Money Factor & Rate Options
Base Money Factor (Buy Rate): Enter the base money factor from the leasing company. It sets the rent charge, the part of your payment that is similar to interest on a loan.1 A common rule of thumb multiplies it by 2,400 to compare it with an APR.4
MF Adjustment (Markup / Markdown): Enter any markup the dealer adds to the money factor. Use a negative number if you got a rate discount.
Lender Minimum MF (Floor): If your leasing company sets a lowest money factor it allows, enter it here. Leave it at 0 if it sets none. The calculator will not let the money factor after any markup or markdown go below this number.
Number of Security Deposits (MSDs): Pick how many multiple security deposits you want to make. Each one lowers your money factor by the amount you enter under Advanced Options. MSDs are refunded at lease end.
Waive Acquisition Fee: Check this box if the dealer is waiving the bank fee by rolling it into your money factor instead of charging it as a separate fee.
One-Pay Lease: Check this box if you want to pay the entire lease in one upfront payment. Enter any money factor reduction your leasing company gives for it under Advanced Options.
Fees & Capitalized Costs
Acquisition Fee (Bank Fee): Enter the fee the leasing company charges to set up the lease. Choose whether to pay it upfront or roll it into your monthly payment.
Dealer Fees: Enter the dealer's documentation and processing fees. Choose whether to pay them upfront or capitalize them into the lease.
Government / Registration Fees: Enter your state registration, title, and license fees. Choose whether to pay them upfront or capitalize them.
Down Payment / Cap Cost Reduction: Enter any cash you want to put down to lower your monthly payment. Keep in mind that a down payment on a lease is not refundable if the car is totaled.2
Trade-In Equity: Enter the value of your trade-in. Use a positive number for positive equity. Use a negative number if you owe more than the car is worth.
Zero Drive-Off: Check this box to roll all signing costs into your monthly payment so you pay nothing upfront except refundable security deposits.
Incentives & Rebates
Taxed Incentives: Enter any rebates or discounts that reduce your cap cost but are still subject to sales tax.
Untaxed Incentives: Enter any rebates or discounts that reduce your cap cost and are not taxed.
Post-Sale / Mail-In Rebate: Enter any rebate you receive after the deal closes. This does not lower your monthly payment but reduces your total cost.
Disposition Fee: Enter the fee the leasing company charges at lease end if you return the car instead of buying it.
Tax Configuration
Registration State: Pick your state from the list. This will auto-fill your tax rate and the correct tax method for your state.
Sales Tax Rate: Enter your total sales tax rate, including state and local taxes. The state selector fills in the base rate, but you may need to add local tax.
Tax Method: Choose how your state applies sales tax to leases. Method A taxes each monthly payment. Method B taxes all payments upfront. Method C taxes the full selling price upfront. Your state selection sets this automatically, but you can change it.
Advanced Options
MF Reduction per MSD: Enter how much each security deposit lowers the money factor, as set by your leasing company.
One-Pay MF Reduction: Enter how much the money factor drops when you choose a one-pay lease.
Notes / Deal Memo: Type any notes about the deal, such as the trim level, dealer name, or special terms. These notes appear on your printed summary.
Lease vs. Finance Comparison
Loan APR: Enter the annual interest rate you would get if you financed the car with a loan instead of leasing.
Loan Term: Enter the number of months for the finance loan you want to compare against your lease.
How Car Leasing Works
A car lease is a way to drive a new vehicle without buying it. You pay to use the car for a set number of months. At the end, you give the car back to the dealer. Think of it like renting, but for a longer time.
What You Pay For in a Lease
Your monthly lease payment is based on two main things: depreciation and a rent charge. Depreciation is the drop in the car's value while you drive it. The rent charge is similar to interest on a loan.1 These two costs added together make up your base monthly payment before taxes.
Key Lease Terms to Know
MSRP is the sticker price on the car. The selling price is what you and the dealer agree to pay. A lower selling price means a lower payment. The residual value is what the car is expected to be worth when the lease ends. A higher residual means less depreciation, which means a lower payment.
The money factor is a small decimal number the leasing company uses to work out the rent charge.1 It is not a lease rate.1 A common rule of thumb multiplies it by 2,400 to compare it with a normal APR.4 A lower money factor saves you money each month. If you want to compare this against a traditional interest rate, converting between the two formats makes it easier to see which deal costs less.
The capitalized cost is the total amount being financed in your lease. It starts with the selling price, adds any rolled-in fees, and then subtracts your down payment, trade-in equity, and incentives.2
Costs at Signing and Over the Full Term
When you sign a lease, you often pay a first month's payment, a down payment, an acquisition fee (a bank fee to set up the lease), dealer fees, and government registration fees. Some of these can be rolled into your monthly payment instead of paid upfront.
At the end of the lease, most leasing companies charge a disposition fee if you return the car, to cover part of the cost of reconditioning and selling it.5 You may also owe charges for excess miles or wear and tear. Beyond the lease payment itself, remember to factor in ongoing costs like fuel, car insurance, and maintenance when planning your monthly budget.
Tips for Getting a Good Lease Deal
Negotiate the selling price down just like you would if you were buying. Look for manufacturer rebates and incentives. Choose a car with a high residual value. This is the single biggest factor in a low lease payment. Ask the dealer what the base money factor is and whether they have marked it up. A strong lease deal keeps your total monthly cost low compared to the car's MSRP.
