If you have a cell that contains a value, you may want to devise a way to add together all the digits in the value. For instance, if a cell contains the value 554, you might want to determine the sum of 5+5+4, which is 14.
There are several ways you can approach this task. (Doesn't that always seem the way in Excel?) The first is to use a formula that relies on several functions:
=SUMPRODUCT(--MID(A1,ROW(INDIRECT("1:" & LEN(A1))),1))
This regular formula will sum the digits in any integer value (in cell A1) in a simple, elegant manner. This is not the only possible formula, however. The following is an array formula (terminated by pressing Ctrl+Shift+Enter) version of the same formula:
=SUM(1*MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1))
Either of these formulas work fine if the value in A1 is a positive whole number. If there are any non-digit characters in the number (such as a negative sign or a decimal point), then the formulas return a #VALUE! error.
These are not the only formulas possible for this type of calculation. You can find some other examples of formulas in the Microsoft Knowledge Base:
http://support.microsoft.com/?kbid=214053
You can also use a user-defined function to return the desired sum. The following macro steps through each digit in the referenced cell and calculates a total. This value is then returned to the user:
Function AddDigits(Number As Long) As Integer Dim i As Integer Dim Sum As Integer Dim sNumber As String sNumber = CStr(Number) For i = 1 To Len(sNumber) Sum = Sum + Mid(sNumber, i, 1) Next AddDigits = Sum End Function
To use this function, just use a formula such as =AddDigits(A1) in a cell. An even more compact user-defined function (invoked in the same manner) is the following:
Function AddDigits(ByVal N As Long) As Integer Do While N >= 1 AddDigits = AddDigits + N Mod 10 N = Int(N / 10) Loop End Function
Unlike the earlier macro, this version doesn't convert the cell contents to a string in order to process it. Instead, it steps through each digit of the value, stripping off the last digit and adding it to the total.

As a child we had a game to sum the digits until a single figure was arived at. Here is the function
Function Add2Digit(value) As Integer
Dim i As Integer, Char As Integer
Dim tmp, tmp2
For i = 1 To Len(value)
Char = Mid(value, i, 1) * 1
If IsNumeric(Char) Then tmp = tmp + Char
Next i
Do
For i = 1 To Len(tmp)
Char = Mid(tmp, i, 1)
tmp2 = tmp2 + Char
Next i
If tmp2 > 10 Then
tmp = tmp2
tmp2 = 0
Else
Add2Digit = tmp2
Exit Do
End If
Loop Until tmp < 10
End Function

Thanks for the Tips Allen,
I have designed a formula which can sum of numbers in a cell which can contain Alphanumeric.
Eg-> If Cell A1 has text "D25R67T726B"
Formula to get sum of numbers would be =SUM(IF(ISNUMBER(VALUE(MID(A16,ROW(INDIRECT("1:"&LEN(A16))),1)))=TRUE,VALUE(MID(A16,ROW(INDIRECT("1:"&LEN(A16))),1)),0))
This is a array formula[should be pushed with CTRL+SHIFT+ENTER]
To get only a count of numbers in a cell would be.
=SUMPRODUCT(--ISNUMBER(VALUE(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1))))
This can be pushed by a normal enter button.
Thanks
Harish

The following Array Formula should fulfil the task (even for decimal and/or negative numbers):
=SUM(IFERROR(--MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1),))

Here is a user defined function that works with negative numbers and numbers with decimals as well:
Function AddDigits(Number As String) As Integer
Dim i As Integer, Char As String
For i = 1 To Len(Number)
Char = Mid(Number, i, 1)
If IsNumeric(Char) Then AddDigits = AddDigits + Char
Next
End Function
