How This Calculator Works

Our lease vs buy calculator performs a comprehensive financial analysis comparing the total cost of ownership for both leasing and purchasing options. The calculation considers all majorfinancial factors that impact your decision over the comparison period.

The Analysis Framework

Buying Costs

  • • Down payment + taxes
  • • Total loan payments with interest
  • • Minus: Vehicle equity at loan end
  • • = Net cost of ownership

Leasing Costs

  • • Lease down payment
  • • Total monthly lease payments
  • • Excess mileage fees
  • • = Total lease cost (no equity)

Key Calculation Components

Depreciation & Equity

  • Assumes 15% annual depreciation rate
  • Calculates remaining vehicle value
  • Equity reduces net cost of buying
  • Leasing provides no equity buildup

Mileage Considerations

  • Standard lease: 12,000 miles/year
  • Excess mileage: $0.25 per mile penalty
  • High mileage favors buying
  • No mileage restrictions when buying

Financial Formulas Used

Monthly Loan Payment:
PMT = P × [r(1+r)^n] / [(1+r)^n - 1]

Where P = loan amount, r = monthly rate, n = number of payments

Vehicle Depreciation:
Value = Initial_Price × (1 - 0.15)^years

Assumes 15% annual depreciation (industry average)
