Multiply 2 columns and then sum the totals VBA

[aheverett1]

Hello,

Is there a way to take multiply say A1 * B1, A2 * B2, A3 * B3 then put the extended totals add them together and add those up?

Like this but without using a third column and just putting the total of 196 in a cell?

QTY	Price	Ext price
1	66	66
1	85	85
3	15	45
	Total	196

<colgroup><col style="width:48pt" width="64" span="3"> </colgroup><tbody>
</tbody>

try this:

Sub NoHelper()
    Dim i As Long, lr As Long
    Dim x As Double, y As Double
    lr = Range("A" & Rows.Count).End(xlUp).Row
    x = 0
    For i = 2 To lr
        y = Range("A" & i) * Range("B" & i)
        x = x + y
    Next i
    Range("A" & lr + 1) = "total"
    Range("B" & lr + 1) = x




End Sub

try the following

Excel 2010
	A	B
1	QTY	Price
2	1	66
3	1	85
4	3	15
5	Total	196
6a

B5	=SUMPRODUCT(A2:A4,B2:B4)

OK, should have been a little more specific. My first range actually starts B6 and the other range starts at I6

Thought this would fix it, but it did not.

Private Sub CommandButton1_Click()
Dim i As Long, lr As Long
Dim x As Double, y As Double
lr = Range("B6" & Rows.Count).End(xlUp).Row
x = 0
For i = 2 To lr
y = Range("B6" & i) * Range("I6" & i)
x = x + y
Next i
Range("B6" & lr + 1) = "total"
Range("I6" & lr + 1) = x
End Sub


Also, how would i output the total or the loop into cell "I1"?

That worked beautifully! That's a new formula to me.

Amended Code to fit your better description:

Option Explicit
Sub Nohelper()
    Dim i As Long, lr As Long
    Dim x As Double, y As Double
    lr = Range("B" & Rows.Count).End(xlUp).Row
    x = 0
    For i = 6 To lr
        y = Range("B" & i) * Range("I" & i)
        x = x + y
    Next i
    Range("I1") = x


End Sub
