Calculating
an Economic Service Life
(Problem
Description)
To
illustrate the approach to develop a Web-based program to create an Excel file,
we followed an example[1]
to generate a two-part worksheet. The first one is the after-tax salvage
value generation, and the second one is the economic service life calculation on
after-tax basis. Once again, our objective is to generate an Excel table. The
required input data set would be
![]() |
Investment |
![]() |
Tax
rate (%) |
![]() |
Current
Book value |
![]() |
MARR
(%) |
![]() |
Holding
period of the asset—(example 7 years) |
![]() |
Expected
annual O&M costs over the holding period. |
![]() |
Annual
depreciation amounts over the holding period |
![]() |
Expected
market (salvage) value of the asset over the holding period. |
