Excel SUMPRODUCT with dynamic column range to sum - excel

A B C D
1 Department Jan Feb Mar
2 Marketing 100 200 300
3 R&D 150 250 350
4 Marketing 300 400 500
I have a sample file like the above table.
The SUMPRODUCT formula below only sums the specific rows and column, which is row 2 to 20 and column B to C for summing
=SUMPRODUCT((A2:A20="Marketing")*(B2:C20))
Actual formula (from comments):
=SUMPRODUCT(INDEX(BW!$A$3:$AE$3,MATCH(C$35,BW!$1:$1,0)+MATCH("JAN 2016",BW!$F$2:$R$2,0)-1):INDEX(BW!$A$108:$AE$108,MATCH(C$35,BW!$1:$1,0)+MATCH("A‌​UG 2016",BW!$F$2:$R$2,0)-1)*(BW!$B$3:$B$108=$E$1))
My questions, is there a way to make SUMPRODUCT dynamic, in a sense, it knows the first row to take will be 2nd and ends at 20.
As for the dynamic column to sum, it'll depend on the criteria. i.e. if the criteria is Feb and Mar, it'll take column C2:D20...again, the row is dynamic as well.

If you turn your range into a table called Table1 then the following should work:
=SUMPRODUCT((Table1[Department]="Marketing")*(INDIRECT("Table1[[Jan]:["&VLOOKUP("*",Table1[#Headers],COLUMNS(Table1),FALSE)&"]]")))

To make the SUMPRODUCT dynamic we can use INDEX/MATCH to find the extents of the data.
Then all that is need is to put the months wanted listed in one cell, I used I7
=SUMPRODUCT((ISNUMBER(SEARCH($B$1:INDEX(1:1,MATCH("ZZZ",1:1)),I7)))*($A$2:INDEX(A:A,MATCH("ZZZ",A:A))="Marketing")*B2:INDEX(A:DD,MATCH("ZZZ",A:A),MATCH("ZZZ",1:1)))
The INDEX(A:A,MATCH("ZZZ",A:A)) will find the last cell with text in Column A, and use that to set the extent of the dataset.
For the Last column we use INDEX(1:1,MATCH("ZZZ",1:1))

If you are not going to work with a ListObject (aka Structured) table, then a dynamic named range would certainly help.
Go to Formulas, Defined Names, Name Manager and when the Name Manager dialog opens, click New.
Give your defined name range a unique name; I've chosen Departments.
Leave the Scope as workbook and use the following formula for the Refers to:  =BW!$A$1:INDEX(BW!$A:$M, MATCH("zzz",BW!$A:$A ), MATCH(1E+99,BW!$1:$1 )) Columns A:M will cover a Department column and Jan through Dec. Note that Jan 2016-Dec 2016 are real dates (e.g. 1/1/2016 to 12/1/2016) formatted as mmm yyyy.
You should end up with the following dynamic named range:
Now you can 'shape' the sections of the defined range using INDEX/MATCH function pairs.
=SUMPRODUCT((INDEX(Departments, 0, 1)=Q3)*
(INDEX(Departments, 0, MATCH(R3, INDEX(Departments, 1, 0), 0)):
INDEX(Departments, 0, MATCH(S3, INDEX(Departments, 1, 0), 0))))

How to create different date ranges based on criteria?

I have a table with two active columns. In Column A I have all the dates between, let`s say, January 1, 2012 to December 31, 2019. In column B I have a corresponding name. For instance:
[
etc.
I want to create ranges based on criteria, like:
The trick is, this should be done by calendar year, which means that during the 8-year period, I should have 8 set of 3 columns (from / to / name), one for each calendar year. If one range covers two years (let's say, November 1, 2012 to February 1st, 2013), the last row of 2012 should read
2012-11-01 to 2012-12-31
while the first row of 2013 will read
2013-01-01 to 2013-02-01
I managed to separate the ranges, but for some reason I am not able to go further and do that for each calendar year. Is there a way to do that?
Let's assume you want to place your 8 set of 3 columns starting from column G and that your list in the range D:F has headers in row 1 and data from row 2 on. In cell G1 write down your first year (2012), in cell H1 "From", in cell I1 "To" and in cell J1 "Name".
Now in cell H2 write this formula:
=IF(IF(OR(IF(AND($E2>=DATE(G$1,1,1),$D2<=DATE(G$1,12,31)),1,0),IF(AND($D2>=DATE(G$1,1,1),$E2<=DATE(G$1,12,31)),1,0)),1,0),MAX($D2,DATE(G$1,1,1)),"")
In cell I2 write this formula:
=IF(IF(OR(IF(AND($E2>=DATE(G$1,1,1),$D2<=DATE(G$1,12,31)),1,0),IF(AND($D2>=DATE(G$1,1,1),$E2<=DATE(G$1,12,31)),1,0)),1,0),MIN($E2,DATE(G$1,12,31)),"")
In cell J2 write this formula:
=IF(AND(H2<>"",I2<>""),F2,"")
Drag the 3 of them all the way down accordingly to your need. You can then copy the G:J range and paste any time you need next to itself; just change the year in the top left cell and it should do the trick.

Find an intersecting value for each row and column in excel

I have monthly data in rows in column A. I also have monthly data in headers from column B to Column G. In Column H i have current month populated for all rows. I would like to display the value where, for example if the month in row is Jan and current month is Mar, then find the value where Jan and Mar intersect and do this for all rows. I tried using the following formula in Column J but it only gives the first value when it works. The result in Column I is desired. Attached is the picture for clarity.
=INDEX(B1:H2,MATCH(A2,$A$1:A2,0),MATCH(A2,$B$1:H2,0))
You can do it with SUMPRODUCT.
I made a fake dataset with different values than the ones you show, so i could test properly if changing Current month would work.
It works even if column CurrentMonth holds different months
My formula is:
=SUMPRODUCT(--($B$1:$G$1=H2);B2:G2)
This is how it works:
--($B$1:$G$1=H2) will return an array of 1 and 0 if range B1:G1 is equal to current month in that row. So in case CurrentMonth=Mar then it will return {0;0;1;0;0;0}
With SUMPRODUCT we multiply previous array by range B:G in current row, so for row 2, it would be B2:G2. So as example, it would be {0;0;1;0;0;0} * {1;2;3;4;5;6} = {0;0;3;0;0;0} and we sum up this array, getting 3
just use INDEX with one MATCH:
=INDEX(B2:G2,,MATCH(H2,$B$1:$G$1,0))

How to create a dynamic formula to find the average of a set of values for a given vector

I am trying to create a formula that gives me the average of the last 12 entries in a given dataset depending on the associated vector.
Let's make an example:
I have in column F2,G2,H2 and I2 dates, Company1, Company2 and Company3 respectively. Then from row3 to row 33 I have months dates starting from May 2016.
Date Company1 Company2 Company3
May-16 2,453,845
Jun-16 13,099,823
Jul-16 14,159,037
Aug-16 38,589,050 8,866,101
Sep-16 63,290,285 13,242,522
Oct-16 94,005,364 14,841,793
Nov-16 123,774,792 7,903,600 41,489,883
Dec-16 93,355,037 12,449,604 69,117,105
Jan-17 47,869,982 13,830,712 83,913,764
Feb-17 77,109,905 10,361,555 68,176,643
The goal is to create a formula that, when I drag it down, correctly calculates the average of the last 12 values for a given company.
So for example i would have, say in table "B2:C5":
Company1 76,856,345
Company2 11,120,859
Company3 65,674,349
And, if a new Company4 is added to the list, then I just have to drag it down the formula, to calculate the average of the last 12 months for Company4.
Until now, I have came up with this formula:
=AVERAGE(LOOKUP(LARGE(IF(ISNUMBER(G:G),ROW(G:G)),ROW(INDIRECT("1:"&MIN(12,COUNT(G:G))))),ROW(G:G),G:G ))
This formula correctly calculates the average of a given column, considering only the last 12 values. The last step would be to come up with a formula that includes all the columns and then calculates the average for the given company.
Thanks!
I recommend that you use a named range to define your data in columns G:I. When a company is added, just modify the named range's specs. I used the name Target. Of course, you can replace it with $G:$I if you feel so inclined but I would rather recommend reducing the number of rows in the range, which is easier to manage when it is named.
Use the formula below to extract the company names from the first row of Target into the first column of your averages table. This is to ensure that the names are spelled identically in both locations.
=INDEX(Target,1,ROW()-2)
The number 2 indicates the number of rows above the row containing the formula. it is copied here from cell M3. There, ROW()-2 creates the number 1, counting sequentially as the formula is copied down.
Now I have the formula below in my cell N3 and copied down.
=SUM(INDEX(Target,0,MATCH($M3,INDEX(Target,1,0),0)))
The formula simply sums up the columns G, H, and I in 3 consecutive rows.
In the final step I inserted the range definition established above, meaning excluding the SUM() function, into your existing formula.
=AVERAGE(LOOKUP(LARGE(IF(ISNUMBER(INDEX(Target,0,MATCH($M3,INDEX(Target,1,0),0))),ROW(INDEX(Target,0,MATCH($M3,INDEX(Target,1,0),0)))),ROW(INDIRECT("1:"&MIN(12,COUNT(INDEX(Target,0,MATCH($M3,INDEX(Target,1,0),0))))))),ROW(INDEX(Target,0,MATCH($M3,INDEX(Target,1,0),0))),INDEX(Target,0,MATCH($M3,INDEX(Target,1,0),0))))

Vlookup and sum all instances of the matching lookup

this is probably an extremely basic problem but I can't figure a way to do this within Excel.
I have a list of values IDs from a regional sales manager,
he wants to see if his figures have been inputted into the monthly report and are reporting correctly.
However, as he sells by region and we report by product we have multiple instances of his ID by Product
so our monthly report.. for example
ID Value
1 16,999
1 22,521
3 400
3 221
5 71
6 22,000
So he has provided me with a list of IDs
1
2
3
4
5
6
and wants a list with its total revenue not just the first match up.
Is an excel limitation or is there a way to do this?
You can use a SUMIF formula. Basically you give it the column to check the value of, then you give it the expected value and finally the colum to sum.
Option 1 (whole range)
=SUMIF(A:A, 1, B:B)
Option 2 (defined range)
=SUMIF(A1:A7, 1, B1:B7)
Option 3 (Using excel table)
=SUMIF([Id], 1, [Value])

Is this what you're looking for?
=SUMPRODUCT((A1:A5=1)*B1:B5)
Taken from here: Sum values from multiple rows using vlookup or index/match functions
How it works:
An array formula is used to create an array of numbers that gets passed to the SUMPRODUCT formula.
The array formula processes A1 and B1 together, then A2 and B2 and so on... if A1 is equal to 1, B1 is added to the array.

Index/Match Multiple Criteria, Perform Calculation for Each Match

I have two columns in a table that are known as S and D, where S is a date, and D is a duration.
E.g.:
'S' Column
January
February
March
April
'D' Column
60
30
45
30
On a separate sheet, imagine that Row 1 contains a sequence of dates (variable, depends on user menu selection).
Row 2 requires the following calculation:
[(x - s1)/d1 + (x-s2)/d2 + ... + (x-sn)/dn] / n
...where "x" is any date along Row 1.
The calculation would only be done when multiple criteria are matched.
My initial attempt involved creating a separate table, but I think this can be done in a one-cell formula in Row 2. I don't think a sum(index(match)) type would work here considering d1, d2, ..., dn are denominators with different values.
Here is an example attempt:
=SUM((SelectedDate-INDEX(Table[StartDates],MATCH(Criteria1&Criteria2,Range1&Range2,0))/INDEX(Table[Durations],MATCH(Criteria1&Criteria2,Range1&Range2,0))))
It may be important to note that I am able to do this in a two-step fashion. First, I create a table that does the calculation on each row. Then, I reference the table. It would be nice if I can eliminate the need of a "calculation table" in favour of an array-type formula.
I took a guess before most of the comments and suggest the following mainly in case it provides ay ideas or is of help in specifying the requirement more closely. This is "two-step" because the average formula is separate from that for each column, so I appreciate may well be not what is required.
Assuming S and D are labelled data in Sheet2 ColumnsA:B.
Assuming Row1 data rows are labelled in ColumnA.
Assuming dates are not strings (eg January is actually Jan 1) and the differences are in days and always positive, etc.
=(B$1-CHOOSE(COLUMN(),Sheet2!$A1,Sheet2!$A2,Sheet2!$A3,Sheet2!$A4))/CHOOSE(COLUMN(),Sheet2!$B1,Sheet2!$B2,Sheet2!$B3,Sheet2!$B4)
in Row2 to suit and if four data columns, in F2 and copied down to suit :
=AVERAGE(B2:E2)
