Steven's Auto Detailers is trying to decide whether to lease or buy some new equipment for polishing vehicles. The equipment costs $22,000, has a 3-year life, and will be worthless after the 3 years. The aftertax discount rate is 6.2 percent. The annual depreciation tax shield is $1,760 and the aftertax annual lease payment is $6,800. What is the net advantage to leasing?
