Lease Payment Formulas

Quick answer: A standard lease payment is usually the sum of the monthly depreciation charge and the monthly finance charge, plus tax if applicable.

This tool is for estimate math. Actual dealer and state rules may vary.

  • Adjusted Cap Cost: selling price + rolled fees − rebates − trade credit − cap reduction
  • Residual Value: MSRP × residual % or direct residual dollar value
  • Monthly Depreciation: (adjusted cap cost − residual value) ÷ term
  • Monthly Finance Charge: (adjusted cap cost + residual value) × money factor
  • Base Monthly Payment: depreciation + finance charge
  • Monthly Payment With Tax: base monthly × (1 + tax rate), when tax is applied monthly
Common money factor conversion: money factor = APR ÷ 2400 when APR is entered as a percent.

FAQ

What lowers a lease payment the most?

A lower adjusted cap cost, higher residual value, lower money factor, and longer term usually reduce the monthly payment.

What is residual value?

Residual value is the vehicle’s projected value at lease end. Many lease programs express it as a percentage of MSRP.

What is money factor?

Money factor is the lease finance rate. A common estimate conversion is APR ÷ 2400.

Why might the dealer number differ?

Dealers may use state-specific tax rules, exact bank fees, first-payment handling, marked-up money factors, or program-specific residual rules.
