As an example, a car worth $30,000 that is leased for 3 years can have a residual value of $16,000 when the lease ends. Residual value is not exclusive to car leases, but can be leases of any type of asset, as long as it depreciates and can be sold at value once again. For most assets, the longer the lease period, the lower the residual value.
