Hi,

pls try
Sub macro()
Dim Res() As Variant
Dim dict As Object
Set dict = CreateObject("Scripting.Dictionary")
Application.ScreenUpdating = False

    For Each c In Range(Range("A2"), Range("A" & Rows.Count).End(xlUp))
        If Not dict.exists(c.Offset(, 2).Value) Then
            dict.Add c.Offset(, 2).Value, c.Offset(, 2).Value
        End If
    Next

Res = dict.Items()
For Idx = 0 To UBound(Res)
    lastRow = Range("A" & Rows.Count).End(xlUp).Row
    Range("A" & lastRow).Offset(Idx + 1, 1) = "Average"
    Range("A" & lastRow).Offset(Idx + 1, 2) = Res(Idx)
    Range("A" & lastRow).Offset(Idx + 1, 3).FormulaR1C1 = "=averageIF(R2C3:R" & lastRow & "C3,RC[-1],R2C4:R" & lastRow & "C4)"
Next
Range("B" & Rows.Count).End(xlUp).Offset(1) = "Grand Average"
Range("D" & Rows.Count).End(xlUp).Offset(1).Formula = "=average(R2C4:R" & lastRow & "C4)"
Application.ScreenUpdating = True

End Sub
