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 in seconds. 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. Whether you are leasing your first car or comparing offers from multiple dealers, this tool helps you make a smart choice with clear numbers — not 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. You can use our discount calculator to quickly figure out what a specific percentage off MSRP equals in dollar savings.
% 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. This fills in default values for fees, money factor floor, and security deposit limits based on that brand.
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. Miles over 100 will reduce the residual value.
Per-Mile Penalty Rate — Choose the rate used to calculate the residual reduction for demo miles. Most brands use $0.25 per mile. Some use $0.30.
Lease Terms
Lease Term — Pick how many months your lease will last. Common terms are 24, 36, or 39 months.
Annual Mileage Allowance — Choose the number of miles per year included in your lease. A lower allowance means a higher residual value and lower payment, but you may owe overage fees. Use our mileage calculator to estimate how many miles you actually drive each year before picking an allowance.
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. If you want to understand how vehicles lose value over time, our car depreciation calculator can help.
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. This is usually $0.15 to $0.30.
Money Factor & Rate Options
Base Money Factor (Buy Rate) — Enter the base money factor from the leasing company. This works like an interest rate. Multiply it by 2,400 to see the equivalent APR. You can use our APR calculator to compare lease rates against traditional loan rates.
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) — Enter the lowest money factor the lender allows. The calculator will not let your effective rate 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. 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. This usually gives you a lower money factor.
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. If you are comparing this to a purchase, our down payment calculator can help you decide how much to put down on a financed vehicle instead.
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. If you need help with sales tax on other purchases, try our sales tax calculator.
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. The default is 0.00007 per deposit.
One-Pay MF Reduction — Enter how much the money factor drops when you choose a one-pay lease.
Custom Per-Mile Demo Rate — Enter a custom per-mile rate for demo vehicles. This overrides the standard radio button selection above.
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. For a full breakdown of a finance option, use our auto loan calculator to see your monthly loan payment, total interest, and amortization schedule.
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, usually 24 to 48. 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 — our car depreciation calculator can show you how vehicles typically lose value over time. The rent charge is the interest the leasing company charges you for lending you the car. 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 the interest rate on a lease written in a special format. To turn it into a normal APR, multiply it by 2,400. 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.
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 brands charge a disposition fee if you return the car and do not buy or lease another vehicle from them. 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. If you are unsure whether leasing or buying makes more sense for your situation, run the numbers through both this lease calculator and our auto loan calculator to compare total costs side by side.
