Example 3: Calculating NPV. Using the cash flows for the tanning bed given in Example 2 above, calculate its NPV and indicate whether the investment should be undertaken or not. Example 2: Calculate Discounted Payback Period Calculate the discounted payback period of the tanning bed, stated in Example 1 above, by using a discount rate of 10%. - Example 1 Payback period of a new machine - Let's say that the owner of Perfect Images Salon is considering the purchase of a new tanning bed. - It costs $10,000 and is likely to bring in after-tax cash inflows of $4,000 in the first year, $4,500 in the second year, $10,000 in the 3rd year, and $8,000 in the 4th year. - The firm has a policy of buying equipment only if the payback period is 2 years or less. state whether the owner would buy it or not.
