EXCEL: Return the Total of the Last 2 values in a Column

I have a column of numbers, which I add numbers to every week. I would like a formula to return the total of the last two cells in the column, regardless of the number of cells in it, which will always be increasing.

I would like a formula, and not an array, please.

I have attached a simple worksheet as well.

Thanks in advance!

You can use this formula...

=SUMPRODUCT((ROW(A6:A20)>=LARGE(ROW(A6:A20),2))*(A6:A20))

It's also possible to use OFFSET function as you suggest, e.g. allowing for data up to row 1000 (adjust as required) try this formula in A1

=SUM(OFFSET(A6,COUNT(A6:A1000)-2,0,2))

Excellent, Barry!! Your formula works perfectly. Thanks so much, and it's great to see you around and answering my dilemmas for me again! (and extremely accurately, as always.)

Saurabh, thank you, too, but your formula requires me to constantly adjust the range of cells as each new cell of information is entered.

Have a great night!
