What is Car Lease Calculator?
Car leasing is a financial arrangement where you pay for the depreciation and financing of a vehicle over a fixed period rather than purchasing it outright. The monthly lease payment is composed of three primary components: the depreciation fee (the difference between the negotiated price and the residual value, divided by the lease term), the finance fee (the money factor applied to the sum of the cap cost and residual value), and applicable sales tax.
Understanding the mechanics of a lease payment empowers you to negotiate better terms. Unlike a car purchase, where the primary negotiation is the vehicle price, a lease involves three negotiable variables: the cap cost (vehicle price), the money factor (interest rate), and the residual value (set by the leasing company but affected by the term length). Most buyers focus only on the monthly payment without realizing that dealers can adjust the money factor or add hidden fees to increase their profit margin.
This calculator breaks down your lease payment into its individual components -- depreciation fee, finance fee, and tax -- so you can see exactly where your money goes. It also converts the money factor to an approximate APR, making it easy to compare the lease's interest cost to a traditional auto loan.
For a buy comparison, see our Car Loan Calculator, which shows the monthly payment, total interest, and total cost of purchasing the same vehicle with an auto loan.
When to Use This Calculator
- When evaluating a lease offer from a dealership -- break down the payment into its components.
- When comparing lease vs buy for the same vehicle -- see total cost side by side.
- When negotiating with a dealer -- use the money factor and residual as negotiation leverage.
- When planning your transportation budget -- understand the true cost of a 3-year lease.
- When deciding how much to put down -- see the trade-off between monthly savings and upfront risk.
- When comparing offers from multiple dealers -- normalize all offers to total lease cost and APR.
Steps:
- Enter the vehicle's MSRP (Manufacturer's Suggested Retail Price) -- this is the sticker price before negotiation.
- Set the residual value percentage -- your dealer or leasing company will provide this; it varies by vehicle and term.
- Choose the lease term in months (typically 24, 36, or 48).
- Input your down payment (cap cost reduction) and trade-in value if applicable.
- Enter the money factor (ask the dealer) and your state's sales tax rate to calculate the total monthly payment.
Formula
Monthly Depreciation Fee = (Cap Cost - Residual Value) / Lease Term
Cap Cost = MSRP + Added Fees - Down Payment - Trade-In Value
Residual Value = MSRP x Residual %
Monthly Finance Fee = (Cap Cost + Residual Value) x Money Factor
Monthly Tax = (Depreciation Fee + Finance Fee) x Tax Rate (if taxed on payment)
Total Monthly Payment = Depreciation Fee + Finance Fee + Tax
APR = Money Factor x 2,400
Example:
MSRP: $35,000
Residual: 57%
Term: 36 months
Down Payment: $2,000
Trade-In: $0
Money Factor: 0.00208
Tax Rate: 6%
Cap Cost: $35,000 - $2,000 = $33,000
Residual Value: $35,000 x 0.57 = $19,950
Depreciation: ($33,000 - $19,950) / 36 = $362.50/month
Finance Fee: ($33,000 + $19,950) x 0.00208 = $109.86/month
Tax: ($362.50 + $109.86) x 0.06 = $28.34/month
Total Monthly: $362.50 + $109.86 + $28.34 = $500.70/month
APR: 0.00208 x 2,400 = 4.99%
Use Cases
- Evaluating a lease offer from a dealership by breaking down the payment into its component fees
- Comparing lease offers from different dealers for the same vehicle
- Converting the dealer's money factor to APR to understand the true interest cost
- Deciding whether to put money down on a lease or keep the cash
- Planning the total cost of a 3-year lease including all fees and taxes
- Comparing the total lease cost to the total purchase cost of buying the same vehicle
Key Benefits
- See exactly how your monthly payment breaks down into depreciation, finance, and tax components
- Convert the dealer's money factor to a familiar APR percentage for easy comparison
- Compare the total lease cost to the vehicle's MSRP to evaluate the deal's value
- Model how different down payments, money factors, and residual values affect your monthly payment
- Understand the tax impact of leasing in your specific state
- Make a data-driven decision instead of relying solely on the dealer's monthly payment quote
Pro Tips
- Always ask for the money factor and residual value before negotiating -- these are as important as the vehicle price
- Check current lease incentives and buy rates from Edmunds or the manufacturer's website before visiting the dealer
- Negotiate the cap cost down just as you would a purchase price -- every $1,000 reduction lowers your payment by approximately $28/month on a 36-month lease
- Keep your down payment minimal -- the risk of losing it in a total-loss incident outweighs the monthly savings
- Consider a one-pay lease if you have the cash -- you save the finance fee entirely and may get a lower money factor
- Get the dealer to waive or reduce the disposition fee as a condition of the lease -- many will do this to close the deal
Common Mistakes to Avoid
- Focusing only on the monthly payment without asking for the money factor -- dealers can inflate the money factor to increase profit
- Putting a large down payment on a lease -- unlike a purchase, you lose this money if the vehicle is stolen or totaled
- Ignoring the disposition fee ($300-$500) charged at lease end -- add this to total cost when comparing
- Not negotiating the cap cost -- the vehicle price is just as negotiable in a lease as in a purchase
- Failing to account for excess mileage charges -- $0.15-$0.30 per mile over the limit adds up quickly
- Comparing only the monthly payment to a loan payment without considering the total cost over the same period
Key Terms Explained
- Money Factor: The interest rate on a lease, expressed as a small decimal (e.g., 0.00208) -- multiply by 2,400 to get the approximate APR
- Residual Value: The projected value of the vehicle at the end of the lease term, expressed as a percentage of MSRP
- Cap Cost (Capitalized Cost): The total amount financed in the lease -- includes the negotiated vehicle price plus fees minus down payment and trade-in
- Cap Cost Reduction: A down payment that reduces the capitalized cost, lowering monthly payments but increasing risk if the vehicle is totaled
- Depreciation Fee: The portion of your monthly payment that covers the vehicle's loss in value during the lease term
- Finance Fee: The portion of your monthly payment that covers interest -- calculated as (Cap Cost + Residual) x Money Factor
- Disposition Fee: A fee charged at lease end for vehicle inspection and reconditioning, typically $300-$500
- Acquisition Fee: An upfront fee charged by the leasing company to originate the lease, typically $500-$1,000

Example
The Rodriguez family is comparing a lease on a $42,000 SUV. The dealer offers a 36-month lease with 55% residual, money factor 0.00292, and $2,500 down. Cap cost: $42,000 - $2,500 = $39,500. Residual value: $42,000 x 0.55 = $23,100. Depreciation fee: ($39,500 - $23,100) / 36 = $455.56/month. Finance fee: ($39,500 + $23,100) x 0.00292 = $182.79/month. Tax at 7%: ($455.56 + $182.79) x 0.07 = $44.68/month. Total monthly: $683.03. APR equivalent: 0.00292 x 2,400 = 7.01%. Over 36 months, the total lease cost is $683.03 x 36 + $2,500 = $27,089 -- approximately 64.5% of the MSRP. The family decides the 7% APR is high and shops for a lower money factor from a credit union, ultimately securing 0.00167 (4% APR) which drops the payment to $584/month.
Interpreting Your Results
The total monthly payment is what you will actually pay each month -- but the total lease cost is the number that matters for comparison. This is the monthly payment multiplied by the lease term, plus any down payment and fees. Comparing total lease cost to the MSRP gives you a quick sense of value: a good lease typically costs 40-50% of the MSRP over the full term.
The approximate APR lets you compare the lease's interest cost to an auto loan rate. If the lease APR is 6% but you could get a 4.5% auto loan, the lease has a higher interest cost. However, leasing also means you do not own the vehicle at the end, so the comparison is not purely about interest -- it is about the flexibility and lower commitment of leasing versus the equity-building of buying.
The depreciation fee is the largest component of your lease payment. It represents the vehicle's value loss during your use. Vehicles with strong residual values (higher residual percentage) have lower depreciation fees, making them cheaper to lease. This is why luxury vehicles with high resale value sometimes lease for less than economy vehicles with poor residuals.
