Car Lease Calculator
Calculate monthly auto lease payments, money factor conversions, monthly depreciation, rent charges, and sales tax.
What is the Car Lease Calculator?
Auto lease modeling calculates monthly contractual rental payments, depreciation fees, and financing rent charges incurred to operate a vehicle over a term. It computes monthly depreciation by subtracting residual value from net capitalized cost, adding monthly finance rent charges derived from lender money factors. This equips automotive consumers with transparent lease breakdowns to negotiate dealer capitalized cost reductions and compare leasing against outright purchase financing.
