New Customers per Day – Technique by David Hager

 
Hi folks.  Today we are fortunate to have a guest post from David Hager.  He explains a technique for counting how many new customers are acquired or “seen” each day.  (I’m going to think about whether this has web site traffic analysis uses as well – New Visitor vs. Returning Visitor sort of stuff).

***UPDATE:  Inspired by David’s work, I extended this technique to cover per Month, Year, Week, etc.:  http://powerpivotpro.com/2013/01/new-customers-per-day-generalized-to-new-customers-per-month-etc/

Count of New Customers per Day in PowerPivot

By David Hager

Information vital to any company is being able to identify customer patterns. Counting how many new customers per day a company acquires is perhaps the most important data that can be obtained. The following model will show how this can be done with DAX measures in PowerPivot. For comparison, two other measures are included in the Pivot Table (shown in Figure 1).

TotalCustomersPerDay:

=COUNTROWS(Table1)

Note that COUNT(Table1[CustomerID]) would return the same result.

DistinctCustomersPerDay:

=DISTINCTCOUNT(Table1[CustomerID])

This measure returns the number of unique customers.

NewCustomersPerDay:

=CALCULATE([DistinctCustomersPerDay],DATESBETWEEN(Table1[Date], BLANK(),LASTDATE(Table1[Date])), All(Table1[Date]))
CALCULATE([DistinctCustomersPerDay],DATESBETWEEN(Table1[Date], BLANK(),LASTDATE(Table1[Date])-1), All(Table1[Date]))

This formula shows the real power of DAX. The first part of the formula (highlighted in green) returns the running total of the DistinctCustomersPerDay measure. The second part of the formula (highlighted in yellow) returns the running total of the DistinctCustomersPerDay measure up to the previous day of the pivot table row context. The difference affords the number of new customers per day.

Taking my “High Priest” Role VERY Seriously

There are a few themes that I just keep hammering on, month after month.  Most of those revolve around the stunning new future opening up for Excel Pros.  I believe every thing I say about that stuff.  It is REAL.

One of the biggest and most transformational changes is this:  taking your workbooks to the web.  Workbooks were being emailed around back when Roxette topped the worldwide music charts.  PowerPivot workbooks published to a server are a very, VERY different experience, one that inspires MUCH more respect from the person consuming them.

Short Version: Free Forever for Lighter Workloads

This week, Pivotstream is launching something that I’ve been dreaming about for a long time: a way for you (yes YOU, dear reader) to harness the power of PowerPivot server (publishing workbooks as interactive web apps)… for free.

Not a trial. This is more of a Dropbox-style model where lighter usage is completely free, and you only pay if you want more capacity.  I want to remove any barriers I can so that you can experience what I’m talking about (without bankrupting my company of course), and I think we’ve figured out how to do that.  But before I get into details, let me show you something.

Just Add Upload

Thanks to a recent focus group I recruited here on the blog, I learned that many people expect there to be some sort of intensive conversion process – it seems like you would need to put a lot of work into a workbook before it becomes an interactive web application like the ones on our demo site.

So I recorded a video showing that it’s much, MUCH simpler than that.  Just upload Smile

Benefits to Excel Pro

I didn’t have time to cover this in such a short video, so here’s a quick table comparing the old way to the new way, through the eyes of you, the Excel Pro:
