How Is a Lease Payment Calculated?

A lease payment is calculated using three key components — depreciation, finance charge (based on the money factor), and taxes/fees. The lender sets the vehicle’s residual value, money factor, and term. Your monthly payment is the cost of the car’s depreciation plus the finance charge, spread over the lease term plus applicable taxes and fees.

This formula helps explain why negotiating the capitalized cost and choosing a strong residual value can significantly lower your payment.

Key Components of Lease Payment Formula

1. Depreciation Charge

   This is the amount you pay for the vehicle’s loss in value over the lease term.

   Formula:
   Depreciation = Capitalized Cost − Residual Value

   • Capitalized Cost: Negotiated price plus fees

   • Residual Value: Estimated value of the car at lease end

   Example:

   • Capitalized cost: $40,000

   • Residual value (60%): $24,000

   • Depreciation: $16,000 over the lease term

2. Finance Charge (Lease Interest)

   This is your cost to finance the lease, based on the money factor .

   Formula:
   Finance Charge = (Capitalized Cost + Residual Value) × Money Factor

   • Money factor is the lease equivalent of an interest rate

   • Convert to APR by multiplying the money factor by 2,400

   Example:

   • Capitalized cost + residual = $64,000

   • Money factor: 0.00200

   • Finance charge portion: $128/month (approx)

3. Monthly Base Lease Payment

   The lease payment before tax is the sum of:

   Depreciation Charge + Finance Charge

   Using the examples above

   • $16,000 depreciation ÷ 36 months = ~$444.44

   • Finance charge ≈ $128/month

   • Base payment ≈ $572.44

4. Taxes, Fees & Add-Ons

   Depending on your location (state/country), your total monthly payment may also include:

   • Sales tax (varies by jurisdiction)

   • Registration fees

   • Acquisition fee (often financed)

   • Optional add-ons (warranty, protection plans)

   Some regions tax the full lease upfront; others tax monthly payments — this varies by GEO/market.
