What is in this session?
Imagine for a second that Excel cannot add up numbers. And no it cant subtract them either. What would that look like?
A glorified Notepad. That’s right. Excel’s ability to add up numbers, along with features like formulas, charts, pivot tables & BHATTEXT() are what make it such a lovely software. May be not the BHATTEXT(), but we all agree that Excel is so versatile and useful because it can add up numbers (and perform other calculations) with ease.
But how well do you know the SUM formulas of Excel?

How awesome are your SUM skills?
SUM formulas are corner stone of any dashboard or report or meaningful model. So it no surprise that I use them often. My favorite sum formula is SUMIFS(). It is versatile and powerful. I am learning to love DSUM() too. I will share details about it in an upcoming article.
Meanwhile, tell me what is your favorite SUM formula? What are the tricks and techniques you use when writing SUM formulas? Please share your thoughts using comments.

I use SUMPRODUCT on almost every spreadsheet I build  it is hugely powerful and lots of uses.
One of the best is for my financial reporting. I have a row at the top called month and I have a 1 in say the first 3 months (of 12 columns representing the 12 months) and 0 in the other 9.
Then, to report against the budget for 3 months I simply do a sumproduct on the row of 1's and 0's, and the relevant budget line. is gives we the budget for 3 months. Next month I change the value in column 4 to a 1, and hey presto I have the budget YTD for 4 months.

5. Month 1 1 1 0 0 0 0 0 0 0 0 0
7. Budget Sales 12 11 15 18 19 17 16 23 24 18 18 12
Sumproduct(B5:M5,B7:M7) = 38
Change Jul to 1 and the answer becomes 56
I have always found SUM using arrays very useful for summing based upon one or more conditions.
Below is an example using mangos and apples. The data starts in cell A1.
An array using SUM is created by pressing [ALT][SHIFT][ENTER] after entering the formula.
As an example enter the formula
=SUM((A2:A6="Apples")*(C2:C6))
Pressing [ALT][SHIFT][ENTER] and the formula becomes
{=SUM((A2:A6="Apples")*(C2:C6))}
Item Country Amount
Mangos India $100
Mangos USA $200
Apples Mexico $400
Mangos India $300
Apples USA $400
Totals SUM using Arrays
Apples 800 {=SUM((A2:A6="Apples")*(C2:C6))}
Mangos 600 {=SUM((A2:A6="Mangos")*(C2:C6))}
Mangos in India 400 {=SUM((A2:A6="Mangos")*(B2:B6="India")*(C2:C6))}
Mangos in India with Amount greater than $200
300 {=SUM((A2:A6="Mangos")*(B2:B6="India")*(C2:C6>200)*(C2:C6))}
SUM is the only formula so far I have found that works this way.
@Mark... Array SUM is really versatile and powerful. I use it many times.
Btw, for your last example, you can also use SUMIFS.
This will work just the same.
=SUMIFS(C2:C6,A2:A6,"Mangoes",B2:B6,"India",C2:C6,">200")
@Mark
Array required [CTRL][SHIFT][ENTER] not [ALT][SHIFT][ENTER]
