Assuming you mean you have a series of numbers in Col 3, and you want to "bucketize" them by quartile...
Sub DoTheMath()
    Dim LastR As Long
    With ActiveSheet
        LastR = .Cells(.Rows.Count, "c").End(xlUp).Row
        .Range("d2:d" & LastR).Formula = "=VLOOKUP(PERCENTRANK(C2:C" & LastR & _
        .Range("b" & (LastR + 2)) = "Total"
        .Range("c" & (LastR + 2)).Formula = "=SUM(C2:C" & LastR & ")"
    End With
End Sub

Assuming all numbers are positive, and without VBA, you might use the formula:

The equivalent macro is shown below.

Sub Ranker()
Dim dSum As Double
Dim rg As Range
Set rg = Range("C2") 'First cell in range to be summed
Set rg = Range(rg, Cells(Rows.Count, rg.Column).End(xlUp)) 'All the cells with data
dSum = Application.Sum(rg)
rg.Offset(0, 1).FormulaR1C1 = "=CHOOSE(1+4*RC[-1]/" & dSum & ",""D"",""C"",""B"",""A"")"
rg.Offset(0, 1).Formula = rg.Offset(0, 1).Value
End Sub

Brad,I guess it all turns on what those percent values are supposed to mean.  I took them as meaning percentiles, but who knows... :)Patrick
