The local supermarket is considering investing in self-checkout kiosks for its customers. The self-checkout kiosks will cost $45,500 and have no residual value. Management expects the equipment to result in net cash savings over three years as customers grow accustomed to using the new technology: $14,000 the first year; $21,000 the second year; $27,000 the third year. Assuming a 14% discount rate, what is the NPV of the kiosk investment? Is this a favorable investment? Why or why not?
