The lease amount that you see with the car is based on a lease period of 60 months. We look at the tax value of the car and thereby take a residual value of 20% (final period). This amount is the total lease amount. As a down payment you pay 20% of the purchase price. Depending on the period in which you want to lease the car, the total lease amount is divided by the number of months. The amount that remains is the monthly amount that you will pay for the car.
