You asked for subtotal of each row, but give an example for the result of
totaling each column. Your problem needs clarification. However, here is
something to play with.

Each Row:
lastRow = ActiveSheet.Cells(Rows.Count).End(xlUp).Row
For i = 1 To lastRow
Range("D" & i) = WorksheetFunction. _
Sum(Range("A" & i & ":C" & i))
Next

Each Column:
lastRow = ActiveSheet.Cells(Rows.Count).End(xlUp).Row
For i = 1 To 3
With ActiveSheet
.Cells(lastRow + 1, i) = _
WorksheetFunction.Sum(Range(.Cells(2, i), .Cells(lastRow, i)))
End With
Next
