How auto lease is calculated
Monthly depreciation = (adjusted capitalized cost − residual) ÷ lease months. Monthly rent charge = (adjusted cost + residual) × money factor. Apply the chosen tax rate to that combined payment.
Worked example
A $35,000 capitalized cost, $2,000 reduction and $21,000 residual over 36 months gives $333.33 monthly depreciation. At a 0.002 money factor, rent charge is $108; a 7% tax allowance gives about $472.23 per month.
