A new machine can be purchased today for $450,000. The annual revenue from the machine is calculated to be $72,000, and the equipment will last 10 years. Expect the maintenance and operating costs to be $4500 a year and to increase $750 per year. The salvage value of the machine will be $35,000. What is the rate of return for this machine

7.98%

Explanation:

The Rate of Return (ROR) is the gain or loss of an investment over a period of time compared to the initial cost

Starting year 2, Annual O&M cost in year N = Annual O&M cost in year (N - 1) + $750

Annual net benefit  = Annual revenue - Annual O&M cost

In year 10, Annual revenue ($) = 72,000 + 35,000 salvage value = 107,000

Rate of Return (ROR) of Annual net benefit is computed using Excel11 IRR function as follows.
