ERP Cost Benefit analysis

The assumptions are set out first. Make sure you look at all the cells in
the spreadsheet to understand the formula behind each cell.

Discounted Cash Flow Analysis
Present value after 2 years
Present value = Future value
(100+discount rate)2

The formula for “Present value” after n years (where “n” can take any value 0, 1, 2, ….) is:

Present value = Future value*((100+discount rate)/100) -n

An example of the equivalent formula in the Excel spreadsheet is:
Present Value=E27*((100+\$B\$19)/100)^-A27

Where Cell E27 holds the value of “Future value”
Cell B19 (\$B\$19) holds the value for the discount rate
Cell A27 holds the value of the number of years considered (“n”)
(E27 and A28 are known as a relative addresses-if you copy the formula down the
spreadsheet this will increment e.g. to E28 and A28. \$B\$19 is an absolute address and the
formula always points to a fixed cell).

1. Complete the rest of the missing cells (shaded red) and find the NPV. You can use a

2. Complete the following table for increased sales of 3%
•   What is the NPV?
•   Is the project still viable?

Sensitivity analysis

3. Change the value of the projected % increase in sales to 2% then repeat for 3% and
4% and complete the following table (0% and 1% have been entered for you so you can
check you are following the correct procedure).

What if scenario
% increase in sales            NPV
