The below macro will insert a row and assign the subtotal in Col J. Col C
should not have any blanks...

Sub Macro1()
Dim lngRow As Long, lngTemp As Long

lngRow = 3
lngTemp = lngRow - 1

Do While Range("C" & lngRow) < ""
If Range("C" & lngRow) < Range("C" & lngRow - 1) Then
Rows(lngRow).Insert
Range("J" & lngRow) = "=sum(J" & lngTemp & ":J" & lngRow - 1 & ")"
lngRow = lngRow + 1: lngTemp = lngRow
End If
lngRow = lngRow + 1
Loop
Range("J" & lngRow) = "=sum(J" & lngTemp & ":J" & lngRow - 1 & ")"
End Sub
