A small heat pump costs $2,500 to purchase and install now. It has a projected useful life of 18 years and will incur annual maintenance costs of $75 per year in real (year-zero) dollars over the useful life. The projected inflation rate for the maintenance costs is 5% per year. In addition, there is the cost of electricity for the heat pump which is $700 per year also in year-zero dollars and is subject to an annual inflation rate of 9%. The firm's MARR, based on the market interest rate, is 12% per year (im). No market value is expected from the heat pump at the end of the 18 years of service life.
