Calculating Sum of Digits in a Number using Array Formulas [for fun]

Here is a fun formula to write.

Sum of Digits in a number - how to calculate?Given a number in cell, I want you to find the sum of digits in it. So, for eg. if you have the number 3584398594 in a cell, the sum would be =3+5+8+4+3+9+8+5+9+4, equal to 1994. 😛

I am kidding of course, the sum would be 58.

Now, how would you write a formula to find this sum automatically based on the number entered in the cell?

Go ahead and figure it out. If you can, come back and check your answer with mine below.

How to get the sum of digits?

In order to get the sum of digits, we just need to separate and add all the numbers. Sounds simple right? But how!?!

Very simple, we use Array formulas and pixie dust.

First the formula:

Assuming the number is in cell B4, we write the formula,

=SUMPRODUCT(MID(B4,ROW(OFFSET($A$1,,,LEN(B4))),1)+0)

to get the sum of digits.

Note: you need not press CTRL+SHIFT+Enter to get this formula work.

How does this formula work?

We will go inside out to understand this formula.

The portion – ROW(OFFSET($A$1,,,LEN(B4))): Gives the numbers 1,2,3…n where n is the number of digits of the value in B4.

The portion – MID(B4,ROW(OFFSET($A$1,,,LEN(B4))),1): Now gets the individual digits of the number and returns them as array (since the 2nd argument of MID formula is an array.

The SUMPRODUCT: is the pixie dust. It just magically sums up all the digits extracted by MID(). We use a +0 at the end because MID() returns text that needs to be converted to numbers for SUMPRODUCT to work its magic.

How would you have solved this?

I just love SUMPRODUCT Formula. So I use it whenever I can. But you may like other techniques. So please tell me how you would solve this problem using formulas. Post your formula using comments.

Note: while posting your formula, just put it between CODE tags like this:

<code>your formula goes here</code> so that it gets displayed correctly.

Bonus question: How to calculate single digit sum of the digits?

Go ahead and solve it too.

The single digit sum is arrived by summing the sum of digits of sum of digits of … of a number. For ex. the single digit sum for number 3584398594 is 4 (because the sum of digits is 58, whose sum of digits is 5+8 = 13, whose sum of digits is 1+3 =4 and we stop here because 4 is a single digit number).

      Hi there:

      I'm interested in understanding exactly how contestants #'s 1, 8 got their surplus or shortfall to show up at the top of the bar (is this overlapped or stacked somehow) and change colour?  I hope this makes sense.  I've tried to find samples and I can see contestant 8 (cuboo) may have used something called graphomate but I can't use this.  

      I need to create a bar chart that shows budget, and actual variance whether it be a surplus or a shortfall and I would like make it look like option 1 or 8 above but haven't  a clear idea how to do it...any help would be greatly appreciated!

      Regards..Linwe

    #6 is the best here. Simple, no extraneous visual effects.

  3. Kevin Stanford says:

    I was all set to vote for #9...until I noticed its lack of y-axis labels. So I have to go with #6 also.

  4. I think #6,#9 is enough .

    #9 is my favorite

  6. Tony Rose says:

    I agree with Jon - #6 for me.

  7. Gale says:

    8 & 14

  8. Fabrice says:

    I go for # 9 (simple) and #14 (complete)

  9. fulvioo says:

    I go for cuboo #8
    cheers

  10. Robert says:

    #6 for overview at a glance / top management
    #8 for deeper analysis / those who need more detailed information

  11. Bob Gannon says:

    #14 although I think you only need the bottom panel and I then would stack the Center charts vertically to make Center comparisons easier.

  12. Denise says:

    #10 gets my vote.
    If there is a second place, then #14

    Hi, if I was not wrong, Samples 3,4 and 5 were created using Tableau software and not Excel. For more information on Tableau you might want to visit http://www.tableausoftware.com/. It was initially designed by Prof. Pat Hanrahan and his PhD students. I am not their salesperson but I thought someone might want to know more about this particular technology.

    • Linwe says:

      Hi Tin Seong Kam:
       
      Thanks - I have looked at Tableau before.  I have also found the means to reproduce something similar to chart 8 without using graphomate, and also chart 7.  I proposed chart 9  as well but the overlap is confusing to some.
      I am really not too concerned about showing actual budget figures but the variance in $ and % is important for my particular use.  That is why I gravitate to the charts that seem to easily tell us that we have a surplus or a shortfall.  
       
      Thanks!

    Number 8 by far. Even though it's not part of the data display, the comments feature sells me. Variance explanations are as important as the actual variances.

  21. Cyril Z. says:

  25. PublicSectorPlanner says:

    To avoid the summary execution of the person presenting these to an executive team these charts must handle overspending as well as underspending, be comprehensible in 5 seconds and show the key fact clearly. The key fact isn't budget or actual - it's the magnitude of the gap!

    Therefore:

    #14 for nailing the key fact and being able to handle overspending. The winner therefore.
    #6 for nailing speed-reading and being able to handle overspending, but somewhat obscuring the key fact. Second place.
    #8 for nailing information depth and aesthetics. Third place.

    I really wanted #8 to win, but that's the technician's view not the end-user's.

    Does anyone know what type of chart #6 is (chart name?)? Also, how do I create this is Excel 2007?

  31. Hui... says:

    @Shazbot
    I'd call it a Column and Bar chart, but don't get hungup on names

    To make it try this:

    Setup the chart as a Clustered Column Chart
    Change the Series so there is 100% overlap, ie: One column is in front of the other
    Change the Budget series to a line chart
    Set the line color to none
    Set the marker style to a Flat Line
    Change the marker width to make it the same width as the bar
    Change colors and other chart properties to suit

    HI

    Does anyone can help me to a to create chart #7? I'm beginer in excel , I started to work two weeks ago and my boss ask me to follow the budget/actual until the end of the year.
    SO I really need your help.

    @OKI, Greg

    I have made a mockup of #7 and #10
    It is available at:
    http://chandoo.org/wp/wp-content/uploads/2009/04/Bud-Act-visualizaion-challenge-7+10..xlsx

    #10 is a straight, Pivot Chart/Table but the data has been rearranged to get it into the pivot table

    #7 is 2 charts, being a simple Bar Chart and a Scatter Chart with 100% Error Bars
    I have used Named Formulas for the two charts.

    Hi Chandoo,
    Please can you provide a link of the excel sheet for 1. Chart "3 colors and everything is clear"

    I would like to drill into the spreadsheet and learn the secrets as how the chart was made.

    Many thanks,
    Sawan

  44. Hui... says:

    @Sawan
    It is probably 12 seperate charts, I will assume snapped to the underlying cells to ensure they are the same size
    The left 3 Charts have a vertical Axis
    The bottom 4 Charts have a horizontal Axis
    The remainder have no axis
    The remaining text maynot be part of the charts but is probably cell content

    • Chandoo says:

      @Satyapal... you can only use static images or slide animations in Power Point. Not features like pivot tables or drop downs. However, you can embed the entire workbook (or sheet) in a presentation. When clicked this will just open Excel so your users can play with the data.
