Auto Lease Money Factor (Lease Fee)

A fractional decimal interest rate (such as 0.00250) used by automotive captive finance companies to calculate the monthly finance charge on a vehicle lease.

Overview & Practical Application

In automotive leasing, captive finance companies (such as Toyota Financial Services, BMW Financial Services, or Ford Credit) do not quote financing costs as a standard percentage APR on the lease worksheet. Instead, they express the cost of borrowing as a five-decimal Money Factor (also called a Lease Factor or Lease Fee), such as 0.00250.

To convert any auto lease Money Factor into its equivalent Annual Percentage Rate (APR) so you can compare it directly against a traditional auto purchase loan: Equivalent APR (%) = Money Factor × 2,400 *(Why 2,400? Because an auto lease charges interest on the average of the Net Capitalized Cost and the Residual Value — dividing by 2 — across 12 months per year: $2 imes 12 imes 100 = 2,400$.)*

Dealership finance managers ("F&I office") are frequently permitted to "mark up" the captive lender's Buy Rate Money Factor (e.g., from 0.00200 to 0.00280) to capture dealer reserve profit unless the lessee demands the base Tier-1 buy rate.

Mathematical Formula & Calculation

Equivalent APR (%) = Money Factor * 2400 | Monthly Rent Charge = (Net Cap Cost + Residual Value) * Money Factor

Multiplies the decimal Money Factor by 2,400 to reveal the true equivalent APR, and multiplies the sum of Net Cap Cost and Residual Value by the Money Factor to calculate the monthly interest ("Rent Charge").

Variable Definitions:

  • Money Factor=Decimal lease financing factor (e.g., 0.00250 = 6.00% APR)
  • Net Cap Cost=Negotiated vehicle price plus fees minus down payment/rebates
  • Residual Value=Projected end-of-lease wholesale value of the vehicle

Total Base Monthly Lease Payment$604.39/mo

Real-World Underwriting Example

Scenario: You lease a vehicle with a Net Capitalized Cost of $41,000, a 36-month Residual Value of $25,200, and a quoted Money Factor of 0.00250.

Calculation:
Equivalent APR = 0.00250 * 2400 = 6.00% APR.
Monthly Depreciation = ($41,000 - $25,200) / 36 = $438.89/mo.
Monthly Rent Charge = ($41,000 + $25,200) * 0.00250 = $165.50/mo.
Total Base Lease Payment = $438.89 + $165.50 = $604.39/month.

Takeaway: Your Money Factor equals 6.00% APR, resulting in a $165.50/month finance charge and a $604.39/month base lease payment.

Key Underwriting Takeaways

  • Multiply any quoted Money Factor by 2,400 to instantly see the equivalent interest rate in APR.
  • Divide any APR by 2,400 to convert a percentage rate back into a decimal Money Factor.
  • Always ask the dealership for the captive lender’s un-marked-up "Base Buy Rate Money Factor" for your FICO credit tier.
