Understanding Your Porsche Lease: A Detailed Guide
Leasing a Porsche offers a way to drive a dream car with potentially lower monthly payments compared to buying. However, the lease agreement can be complex. This guide breaks down the key components and how they influence your monthly payment, which you can estimate using our Porsche Lease Calculator.
Key Terms and Their Impact:
MSRP (Manufacturer's Suggested Retail Price): This is the sticker price of the Porsche you're interested in. It's the starting point for all negotiations.
Negotiated Price: This is the final agreed-upon price of the vehicle between you and the dealership before any lease-specific fees or credits. A lower negotiated price directly reduces your capitalized cost, leading to a lower monthly payment.
Residual Value: This is the predicted value of the car at the end of your lease term, expressed as a percentage of the MSRP. A higher residual value means the car is expected to hold its value better, resulting in lower depreciation costs for the lessor and thus, a lower monthly payment for you. It's determined by the manufacturer and is typically fixed.
Money Factor: This is essentially the interest rate for your lease, expressed as a decimal. A lower money factor means you'll pay less in financing charges. To convert it to an approximate Annual Percentage Rate (APR), multiply the money factor by 2400 (e.g., a money factor of 0.00150 is roughly a 3.6% APR).
Lease Term (Months): This is the duration of your lease agreement, commonly 24, 36, or 48 months. A longer lease term usually means lower monthly payments because the depreciation is spread over more months, but you'll pay more in total interest and will likely drive a car that is older and has more miles when you decide to lease again.
Acquisition Fee: This is a fee charged by the leasing company to set up the lease. It can sometimes be rolled into the monthly payments or paid upfront.
Disposition Fee: This fee is charged at the end of the lease when you return the vehicle. It covers the costs of inspecting, cleaning, and preparing the car for resale. Some dealerships may waive this fee if you lease or purchase another vehicle from them.
Sales Tax Rate: This applies to your monthly payment in most states. Some states tax the entire capitalized cost upfront, while others tax only the monthly depreciation and financing charges. Our calculator assumes tax is applied to the monthly payment.
Initial Capitalized Cost Reduction: This is any upfront payment you make to reduce the 'rent charge' portion of your lease. This can include a down payment, rebates, or trade-in value. A higher reduction leads to a lower monthly payment.
How the Calculator Works:
The calculator estimates your monthly lease payment by following these general steps:
Calculate Total Monthly Payment: Pre-Tax Monthly Payment + Sales Tax + (Disposition Fee / Lease Term (Months))
Note: This is a simplified model. Actual lease calculations can vary based on specific dealership and manufacturer programs, and state tax laws. Fees like the acquisition fee can sometimes be financed into the capitalized cost.
Example Calculation:
Let's assume you're looking at a Porsche 911 Carrera:
MSRP: $120,000
Negotiated Price: $115,000
Residual Value: 55%
Money Factor: 0.00150
Lease Term: 36 Months
Acquisition Fee: $899
Disposition Fee: $595
Sales Tax Rate: 7.5%
Initial Capitalized Cost Reduction: $2,000
Using these figures in our calculator will provide an estimated monthly payment, helping you budget for your dream Porsche.

// 2. Calculate Amortization (Capitalized Cost)
// This is the base cost that will be financed over the lease term
var capitalizedCost = negotiatedPrice – initialCapitalizedCostReduction;
// 3. Calculate Monthly Depreciation (Portion of vehicle value lost per month)
var monthlyDepreciation = depreciation / leaseTermMonths;
// 4. Calculate Finance Charge (Interest on the average amount owed)
// We use capitalizedCost for the primary finance charge calculation, as per common leasing models.
var financeChargePerMonth = capitalizedCost * moneyFactor;

var preTaxMonthlyPayment = monthlyDepreciation + financeChargePerMonth;
// 6. Calculate Sales Tax on the monthly payment

// Add monthly tax and prorate the acquisition and disposition fees over the lease term.
var totalMonthlyPayment = preTaxMonthlyPayment + salesTax;
// Add prorated fees if they are not covered by initial reduction/upfront payments
// Typically, acquisition fee is part of capitalized cost, disposition fee is end-of-lease.
// For simplicity in monthly payment estimation:
// If acquisition fee is not part of initial capitalized cost reduction, it would be financed.
// However, standard calculation usually includes it in capitalized cost directly.
// We'll add a portion of the disposition fee to the monthly payment for a more comprehensive estimate.
