Example 13/10
Session Links
  • You expect to do lots of depreciation calculations in your company and you want a function macro
  • Pattern it after the depreciation formula that supports the Ripple Principle (Session 8)
  • Here’s the macro:
Function Depreciation(firstPeriod As Range, _
                      nPeriods As Integer) As Double
    If Application.Caller.Column _
           - firstPeriod.Column + 1 <= nPeriods Then
        Depreciation = 1 / nPeriods
    End If
End Function
  • Now let’s learn how to write it.
  • Note: You’ll need access to the Developer Ribbon

The example we’ll work is the depreciation formula from the examples for Session 8. The macro is shown above. Here’s how you would use it.

If you want to compute depreciation for a purchase, you need to know how much depreciation occurs in each period after the purchase. You might set up a range that shows the depreciation per period. Let’s say, for example, that the name of the first cell in that range is First, and let’s say that the name of the cell that holds the number of periods is NPeriods. Then, in each cell of the depreciation range, you would enter:

=Depreciation(First,NPeriods)

Function Macros

We focus on function macros in this course because they’re more likely than command macros to make a real difference in your facility with constructing models. For instance, when your customer wants to see result streams displayed as [Month1, Month2, Month3, Q1 Total, Month4, Month5, Month6, Q2 Total, …], you probably realize that such a layout makes copy/paste and fill very inconvenient. A macro can provide a simple means of producing the preferred layout from a more easily maintained pure month structure. It’s also easy to construct macros for running sums and running differences. Can you think of other applications for function macros that make your models easier to build and maintain?
