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.

Nice post! Invoicing for the small biz or solo entrepreneur is something I see a lot of interest in. Also there are great templates from http://office.microsoft.com/en-us/templates
This is awesome.
I would need a little more. e.g. say I generate a Inv. # 1 with all the details. Once done I can click a button all the relevant details gets stored in some table. Further, when i generate a new invoice those details gets stored in same table but just below the previous invoice.
Is their a way to do this?
I did create a solution you are looking for, however its wrapped in a larger 'Medical Scheduler' and it uses VBA, But you can Save, Update, Lookup, Email, Print & Apply Payments to the Invoice.
You are welcome to download it here:https://www.dropbox.com/s/2yvo0o2tgq9quhe/Medical_Massage_and_Salon_Application-Free.xlsm
The Invoice Items are created from the Appt. Types & Service Items table.

Hi Chandoo,
Thanks for sharing this invoice template, Let me tell you this template will definitely help me since I got a process to handle where this invoice piece comes. Just a small doubt, can we store all the invoice details in PRODUCT & SERVICES sheet. So that whenever I select an invoice number from invoice sheet I can take print out and I can share it as well. Can we do that?? Since I will be dealing with this on monthly basis.
It would be great if you can help me with this.
Thanks in advance for your help!

Please let me know if you have any questions.

Thank you so much Buddy. will check and revert you soon.
Hi, is there any chance that this can work with the "Products & Service" sheet outside of the Invoice sheet. I create multiple invoice files for the numerous clients. Updating the product sheet for each of them maybe a task. Hence, I want to create a MASTER FILE from which data can be picked up without having to insert new data in each of the invoice files.
Possible? Or am I asking for the moon 😉
Thank you so much for tutorial.
This example can be reviewed for the example of the advanced invoice that made with excel userform :https://youtu.be/Qr-4of-38DI
Good Day

Item Code Description Quantity Unit Cost Discount Total
When creating an Invoice template in Excel are you able to utilize the auto row height and wrap feature when the cell is a merged cell? I need to have a number of cells merged together to allow for enough space to type in the description of work performed (lets say cells A-D are merged in each row) however it seems that I am unable to utilize the auto format feature. To work around this I have to manually increase the row height after each entry. Is there a better solution for this? Thank you!
