How is a lease payment calculated?
A lease payment is depreciation plus rent charge plus tax: the selling price minus the residual value, spread over the term, plus interest on the money factor.
That means the two things worth negotiating are the selling price and any dealer-added fees. Residual value and money factor come from the lender. Lowering the selling price by $1,000 on a 36-month lease saves roughly $28 a month before tax.
