About this calculator
A car lease payment has two parts: depreciation (the value the car loses over the lease) and a finance charge on the money tied up. This calculator combines them from the negotiated price, the residual value at lease end, your down payment and the interest rate (converted to a money factor), then adds sales tax.
Frequently asked questions
What is the money factor?
The money factor is the lease equivalent of an interest rate. Convert it to an APR by multiplying by 2,400 (so a 0.0025 money factor ≈ 6% APR). This tool does the reverse, dividing your APR by 2,400.
Why does residual value matter so much?
You only pay for the depreciation — the price minus the residual. A car that holds its value (high residual) depreciates less, so it is cheaper to lease even if it costs the same up front.
