Standard Automotive Lease Payment Formula

Monthly Payment = [ (Net Cap Cost โˆ’ Residual) / Term ] + [ (Net Cap Cost + Residual) ร— Money Factor ] + Monthly Sales Tax
  • Monthly Depreciation Fee = (Net Capitalized Cost โˆ’ Residual Value) / Lease Term in Months.
  • Monthly Finance Fee (Rent Charge) = (Net Capitalized Cost + Residual Value) ร— Money Factor.
  • Money Factor to APR Conversion: Lease APR = Money Factor ร— 2,400 (e.g. 0.00250 ร— 2,400 = 6.0% APR).

Step-by-Step Worked Example

Scenario: Leasing a $35,000 MSRP car negotiated to $33,500 with 60% residual and 0.00220 money factor for 36 months

Calculation Steps:

  1. Monthly Depreciation = ($31,695 โˆ’ $21,000) / 36 = $297.08 / month
  2. Monthly Rent Charge = ($31,695 + $21,000) ร— 0.00220 = $115.93 / month
  3. Base Monthly Payment = $297.08 + $115.93 = $413.01
  4. Monthly Sales Tax (7%) = $413.01 ร— 0.07 = $28.91
  5. Total Monthly Lease Payment = $413.01 + $28.91 = $441.92 / month
Result: The total monthly lease payment is $441.92 ($297.08 depreciation + $115.93 finance fee + $28.91 tax).

How to Use This Calculator

  1. 1Enter the vehicle window sticker MSRP and negotiated selling price.
  2. 2Input cash down payment, rebates, and bank acquisition fee.
  3. 3Specify the lenderโ€™s residual value percentage and lease term in months.
  4. 4Enter the money factor (e.g. 0.0025) or equivalent lease APR (e.g. 6.0%).

Assumptions & Limitations

  • Residual value is strictly calculated off the vehicle window sticker MSRP, not the discounted selling price.

Frequently Asked Questions

How do I convert a lease money factor to an interest rate (APR)?

Multiply the money factor by 2,400. For example, a money factor of 0.00250 multiplied by 2,400 equals an annual interest rate of 6.00% APR.
