In order to calculate your lease residual value in dollars, you will need to know the lease residual percentage being offered by your finance company. Multiply that percentage with the total cost of the vehicle to determine the residual value in dollars. If your leasing company is offering a 30% residual on a vehicle costing $50,000.00, your residual value is $15,000.00. (e.g. $50,000 x .30 = $15,000). While a higher residual value will lower your monthly payment, it will raise the cost of the vehicle at the end of the lease term for parties interested in purchasing at that time. This calculator is designed to give you an estimated payment only. This is not a guarantee of credit approval.
