How to Use the Car Loan Lease Calculator

  1. Enter Car Price or Capitalized Cost – For loans, input the total car price. For leases, input the negotiated capitalized cost.
  2. Input Down Payment or Trade-in Value – Any upfront amount reducing your financed amount.
  3. Enter Loan or Lease Term – Number of months for repayment or lease duration.
  4. Input Interest Rate or Money Factor – Annual interest rate for loans or money factor for leases (convert money factor to interest rate by multiplying by 2400).
  5. Enter Residual Value (For Lease) – Estimated car value at lease end, usually a percentage of MSRP.
  6. Calculate – Get estimated monthly payments for loan and lease options.

Formulas Used in Calculation

Car Loan Monthly Payment Formula:

M = P × (r(1 + r)^n) / ((1 + r)^n − 1)

Where:

  • M = Monthly payment
  • P = Principal loan amount (Car price − down payment)
  • r = Monthly interest rate (annual rate ÷ 12)
  • n = Total number of payments (loan term in months)

Car Lease Monthly Payment Formula:

Lease payments are typically calculated as the sum of:

  • Depreciation Fee = (Capitalized Cost − Residual Value) ÷ Lease Term
  • Finance Fee = (Capitalized Cost + Residual Value) × Money Factor

Monthly Lease Payment = Depreciation Fee + Finance Fee


Example Calculation

Example: Loan

  • Car Price = $30,000
  • Down Payment = $5,000
  • Loan Term = 60 months
  • Annual Interest Rate = 5% (0.05)

Monthly interest rate = 0.05 ÷ 12 = 0.004167
Principal = $30,000 − $5,000 = $25,000

M = 25,000 × (0.004167 × (1 + 0.004167)^60) / ((1 + 0.004167)^60 − 1) ≈ $471.78

Example: Lease

  • Capitalized Cost = $30,000
  • Residual Value = $18,000
  • Lease Term = 36 months
  • Money Factor = 0.00125

Depreciation Fee = (30,000 − 18,000) ÷ 36 = $333.33
Finance Fee = (30,000 + 18,000) × 0.00125 = $60

Monthly Lease Payment = $333.33 + $60 = $393.33

Mileage limits affect residual value and lease terms, but this calculator assumes standard residuals.
