A Pareto chart or pareto graph displays the importance of various factors in decreasing order in columns along with cumulative importance in a line. Pareto charts are often used in quality control to display most common reasons for failure, customer complaints or product defects.
The principle behind pareto charts is called as pareto principle or more commonly the 80-20 rule. According to wikipedia,
The Pareto principle (also known as the 80-20 rule,[1] the law of the vital few, and the principle of factor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.
The pareto chart is a great way to do the pareto analysis. Today, we will learn how to use excel to make a pareto chart.
See an example pareto chart of visits to this website:
(Please note that in this example, the 80/20 rule does not hold as I have chosen very small sample of data. In reality, the 80/20 principle applies to my website as well)
Making a Pareto Chart in Excel
In order to make the pareto chart in excel, first you must have the data ready. Once we have the values for each cause, we can easily calculate cumulative percentages using excel formulas. We will also require a dummy series to display the “cutoff %” in the Pareto chart.
I have arranged the data in this format. You can choose any format that works for you.
Once you have the data ready, making the pareto chart is a simple 5 step process.
1. Make a column chart using cause importance data
In our case, we select the first 2 columns in the above table and then make a new column chart.
2. Add the cumulative %s to the Pareto Chart as a line
Select the third column, press ctrl+c (copy). Now select the chart and press ctrl+v (paste). Excel will add another column series to the chart. Just select it and change the series chart type to “line chart”. Learn more about combining 2 different chart types in excel combo charts.
3. Move the cumulative %s line to secondary axis
Select the line chart, go to “format data series” (you can also press ctrl+1) and change the axis for this chart series from “primary” to “secondary”.
4. Add the cut-off % to the pareto chart
Select the fourth column in our data table, copy and paste it in the chart. This should ideally be pasted as a new line chart. If not, follow step 2 for this as well.
5. Finally, adjust formatting to make the final pareto chart
Now, our basic pareto chart is ready. We should adjust the chart formatting to make it more presentable. Once you are done, the final output will be something like above chart.

When to use Pareto Chart?
Pareto charts can be used,
- During quality control to analyze the causes of defects and failures
- When you want to focus your resources on few important items from a large list of possibles
- To tell the story that attacking problem A might be better than solving problem C, D and F
Pareto charts and pareto analysis has great practical uses for almost anyone in a managerial role.
Have you used Pareto analysis or Pareto charts in your job?
Pareto principle is the first real management lesson I have learned during my MBA. It is the topic for my first presentation too. During the presentation, Anoop, my jovial team mate said, “80-20 principle can be tested anywhere. For eg. in most parties 80% of the beer will be consumed by 20% of people”, and the whole class started laughing.
Jokes apart, I think pareto principle is a very powerful idea told in an extremely simple way. I use the pareto analysis to find best way to invest my time. What about you? Tell me about your experiences of using pareto analysis using comments.

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

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!

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,
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)))
