In early February Sujit asked a question at Chandoo.org, original post.
I require a formula stating criteria [0%-25% output will be 0, 26%-50% output will be 0.1, 51%-75% output will be 0.2, 76%-100% output will be 0.3 & 100% + output will be 0.4]
Kyle, responded with a neat Sumproduct formula
=SUMPRODUCT((B3>{0.25,0.5,0.75,1})*0.1)
I think it is so neat that it is worthy of sharing and detailing here at Formula Forensics:
So today we will pull Kyle’s answer apart to see what’s inside.
Kyle’s Formula
As usual we will work through this formula using a sample file for you to follow along. Download Here.
Kyle’s formula is a Sumproduct based formula
=SUMPRODUCT((B3>{0.25,0.5,0.75,1})*0.1)
Lets look at cell C3 as our example.
;
In C3 we see the formula: =SUMPRODUCT((B3>{0.25,0.5,0.75,1})*0.1)
Which consists of a Sumproduct function and a formula inside the sumproduct.
We know from Formula Forensics 007 that Sumproduct, Sums the Product of the Arrays, and that when there is only 1 array it simply sums the array elements.
In this case the Sumproduct only has a single array as an element
=SUMPRODUCT((B3>{0.25,0.5,0.75,1})*0.1)
and so the (B3>{0.25,0.5,0.75,1})*0.1 component must return an Array of elements for the Sumproduct to sum.
If we now look at the (B3>{0.25,0.5,0.75,1})*0.1 component.
We can see that it consists of a comparison B3>{0.25,0.5,0.75,1}
The result of the comparison is Multiplied by 0.1.
Sujit’s orginal question asked: 0%-25% output will be 0, 26%-50% output will be 0.1, 51%-75% output will be 0.2, 76%-100% output will be 0.3 & 100% + output will be 0.4
And Kyles formula is using B3>{0.25,0.5,0.75,1} to work out which category the value in B3 belongs to.
We can see this if in a blank cell say C5: we enter the following:
= B3>{0.25,0.5,0.75,1} press F9 not Enter.
Excel will respond with ={TRUE,TRUE,TRUE,FALSE}
This is showing us that the 1st, 2nd and 3rd elements in the formula: B3>{0.25,0.5,0.75,1}, are True
In our example the value in B3 is 80% which is 0.8 which is Greater than 0.25 and Greater than 0.5 and Greater than 0.75, but Not Greater than 1.0.
The next part of Kyle’s formula is (B3>{0.25,0.5,0.75,1})*0.1
In a blank cell say C7: enter the following:
= B3>{0.25,0.5,0.75,1}*0.1 press F9 not Enter.
Excel will respond with ={0.1,0.1,0.1,0}
This is showing us the result of
=(B3>{0.25,0.5,0.75,1})*0.1
={TRUE,TRUE,TRUE,FALSE} *0.1
={0.1,0.1,0.1,0}
Sumproduct now only has to add up the Array
=Sumproduct({0.1,0.1,0.1,0})
Which it does returning 0.3.
The Neat Part
The neat part of this is that Kyle has used the 0.1 Multiplier to Force the array to an array of Numbers for Sumproduct to sum.
Had Kyle used: =SUMPRODUCT((B3>{0.25,0.5,0.75,1}))*0.1
Excel would have returned an answer of 0
This is because as we saw in Formula Forensics 007, Sumproduct doesn’t know what to do with the array of True/False, they need to be converted to numerical equivalents for Sumproduct to operate on.
In a spare cell, say C9, enter: =SUMPRODUCT((B9>{0.25,0.5,0.75,1}))*0.1
Excel will respond with 0
Of course that can be fixed by using a double degative of a 1* inside the formula
In a spare cell, say C10, enter either:
=SUMPRODUCT(1*(B9>{0.25,0.5,0.75,1}))*0.1
or
=SUMPRODUCT(- -(B9>{0.25,0.5,0.75,1}))*0.1
Excel will respond with 0.3 as it should
Except that the formula is longer and now has to do 1 more multiplication.

Hi Chandoo,
your recent postings include only Excel 2007 templates. Unfortunately the company I work at still runs Excel 2003. Is it possible to get your awesome files in other excel version as well?
Thanks so much for your great excel stuff!
Is it possible to do this for shifts with hours instead of days? To organise a three shift day?
Thanks in advance,
Stelios
In my organization there are 45 employees i need split then into three shifts ex:A shift:14,B shift:14,C shift:14 and week off:3 kindly help me on this.
@Masthan
You need to understand what rules your company has for the various shifts / roster combinations
Chandoo, I once did a shift control spreadsheet for my team. I put one person in each line, the columns were the days. I put a shift code in each cell indicating in which shift that person should work, or if the person were out that day. I have two codes for being out. One is for vacations and one is to compensate days worked in weekends. This way I was able to count how many persons I have in each shift, how many were on vacations and how many were out compensating (that's the term we use here) weekend worked hours.
Later I included the possibility of a person be in two lines one for normal hours other for overtime. This is mainly used for planning purposes. If you would like I can send you an example. The only problem of this spreadsheet is that we don't have a person view, only this consolidated view.
Hi George, I would like to have a copy of your spreadsheet if you can share it.
Thanks in advance, Chuck
Hi Chandoo,
Where is the code located ? is it VBA ? If so , how do you hide it ? Or it is .NET ?
Thx
@Idan
.
No VBA or code, it is all done with Mirrors.
Only Joking,
.
But there is no VBA or code,
It is all done with Named Formulas and Lookups.
Have alook at the cells in the calander area and Named Formulas in the Formulas, Name Manager Tab.
How can i calculate between two or more different workbooks? Please, reply me as early as possible.
@Anand
Open the workbooks you want to link to
Start a formula = and click and change between workbooks as required.
You can use the View, Switch window menu to change workbooks mid formula
The format for using workbooks is
=[Workbook.xlsm]Sheet1!$A$1
or
=SUM('[Book2.xls]Sheet1'!$A$1:$D$10)
etc
Hi Chandoo,
I am working with a call centre wherein i ned to update at the month end 20 to 30 employees login hours which are defict to track it at the month end is very difficult is there any template which can be made to track that why on a particular day a guy who needs to be on calls was why not on calls.
Thank you so much Chandoo. This is really helping me. As usual, you rock.
What's FortyTwoDays and Calendar in Name manager?
Both are unused and FortyTwoDays doesn't make any sense.
I have a SQL db that contains records of events scheduled/completed on a particular date. Can this method ous building a calendar be used to display those events on the respective day?
Positively awesome!
I'm attempting to help a friend create a schedule for adult classes - and of course its not"paid help". Here is the scenario:

he'd like to see these classes show up in different colors within the same month's calendar chart. He can draw it, but I'd like to see it done automatically through data, and I just can't visualize it, but I KNOW this will work - can you help?

Dear chandoo,
Try many way to download still can't access. Any way we want to try out 3 shifts with 3 guys in a group .eg Group A Morn, Group B Night and Group C Rest. And every each group must work on sunday to take turns. In fact we are security teams so that's why sunday is required to work. Pls guide and show how to put in the working calendar. Thank you in advance.
I've been trying to copy and/or recreate this to use in a workbook I'm doing for the transportation department I'm working for. I need to have the calendar on the first sheet in my document (it has graph's from data on another sheet). I'm trying to use it to track (with the conditional formatting) accidents and injuries. I've redone the conditional formatting to do 4 different accident types (no injury, near miss, OSHA recordable injury and work loss injury), but when I enter the formula's you have in the calendar portion where it says "DateOfFirst-FirstWeekDay" I can't figure out how you did that. Are you able to help?
I would like to use Excel to solve the following problem for a community work. I want to create a Driver schedule for a given month from a pool of volunteers for a community service. Each of these volunteers can drive only on specific days in a week. I would like to populate the driving schedule for each weekday with primary, secondary and tertiary drivers in a random fashion so that I do not overburden one person. I would greatly any help you can provide.
Hi chandoo,
Thanks for your valuable effort for create this template and let me know how to add multiple employees in the the Roaster.
Hi Chandoo,
This article on shift roaster is very helpful. Could you please let me know how i can use the same for n number of resources who work 24/7, considering their leaves and holidays?
Thanks,
Savitha
Hi Chandoo,
This article on shift roaster is very helpful to all. Could you please let me know how i can use the same if I want to add for some more shifts, since the color is not getting change if I add more shifts like 4,5 etc.,
Thanks,
Murali
nice post
How can I change the date to 2017 under Shift Data worksheet.
solution 1:
mydata=B2:C16
stoplist=E2:E8
=LET(RNG,A2:A16,SMR,C2:C16, F,(RNG=E2)+(RNG=E3)+(RNG=E4)+(RNG=E5)+(RNG=E6)+(RNG=E7)+(RNG=E8),SUM(SMR)-SUM(SMR*F))
=LET(RNG,A2:A16,SMR,C2:C16,RH,N(B2:B16=B2), F,(RNG=E2)+(RNG=E3)+(RNG=E4)+(RNG=E5)+(RNG=E6)+(RNG=E7)+(RNG=E8),TOT,SUM(SMR)-SUM(SMR*RH*F),SUM(SMR*RH)-SUM(SMR* RH*F))
ALTERNATE SOLUTION
=SUM(C2:C16)-SUM(FILTER(C2:C16,ISNUMBER(BYROW(A2:A16,LAMBDA(a,TOROW(SEARCH(a,E2:E8),2))))))
=SUM((B2:B16=B2)*(C2:C16))-SUM((ISNUMBER(BYROW(A2:A16,LAMBDA(a,TOROW(SEARCH(a,E2:E8),2))))*(B2:B16=B2)*(C2:C16)))
