Here is another possibility without the need for a Help Column.
In this code it assumes that Column C (3) is free. Change as required.
Code:
Sub One_More_Way()
Dim j As Long, lr As Long
lr = Cells(Rows.Count, 1).End(xlUp).Row '<---- Column A (1) is being checked. Change as required
For j = 1 To 26
'The number 3 in Cells(j, 3) in the next line is Column C (3rd Column).Change as required.
Cells(j, 3).Value = Application.WorksheetFunction.CountIf(Range("B1:B" & lr), _
Chr(64 + j) & "*") & " x " & Chr(64 + j) & "'s"
Next j
End Sub
