When it comes to business intelligence and data visualization, one of the most effective ways to uncover high-impact insights is by creating a Pareto Chart in Power BI. This chart, built on the Pareto Principle (80/20 rule), allows organizations to quickly identify the small percentage of factors that drive the majority of results.
This visualization helps businesses identify the vital few factors that contribute to the majority of outcomes, such as revenue, sales, customer retention, or defects. By creating a Pareto Chart in Power BI, analysts and decision-makers can quickly prioritize resources, improve efficiency, and uncover hidden patterns in data.
In this blog, I’ll describe how to create a Pareto Chart in Power BI step-by-step, along with its applications, benefits, and business use cases.
What is Pareto Analysis?
Pareto Analysis is a data analysis technique based on the Pareto Principle (80/20 rule): “80% of the benefits come from only 20% of the effort.”
This principle is widely applied in business intelligence (BI), analytics, and performance measurement to identify key drivers of success.
Here are some real-world examples:
- 20% of employees deliver 80% of the work.
- 20% of drivers cause 80% of accidents.
- 80% of revenue is generated by 20% of the company’s products.
By building a Pareto Chart in Power BI, businesses can visualize these insights and make better decisions on sales, quality management, and customer prioritization.

How to Create a Pareto Chart in Power BI
A Pareto Chart in Power BI combines bars (to represent sum values) and a line graph (to represent the cumulative total percentage). This hybrid visualization makes it easy to see which categories contribute most to overall performance.
Step 1: Choose the Right Visual
Pick the visual “Line and clustered column chart.”
- Drag the Sales and Product Category fields from the data pane into the Value field.
- Ensure the Sum of Sales is sorted in descending order.
This ensures the chart highlights the highest contributors first.
Step 2: Calculate the Cumulative Sum of Sales
Use the following DAX expression to create a measure for cumulative sales:
Cumulative sales =
Var A= SUM(Orders[Sales])
return
SUMX(
FILTER(
SUMMARIZE(ALL(Orders),Orders[Product Sub-Category],
“revenue”,[Sales_]),
[revenue]>=A),
[revenue]
)
This creates a running total of sales across product categories.
Step 3: Create a Cumulative Percentage
To display the Pareto line, calculate the cumulative percentage:
cumulative percentage =
Var A=[Cumulative sales]
var B=CALCULATE([Sales_],All(Orders))
return DIVIDE(A,B)
Drag this measure to the Line Y-axis field to visualize the contribution percentage.
Step 4: Add the 80% Reference Line
Add a static line at 80% for true Pareto Analysis:
line = 0.8
This helps identify which categories generate 80% of total revenue.
Why Use a Pareto Chart in Power BI?
A Pareto Chart in Power BI is not just a visualization, it’s a business optimization tool. Organizations use it to:
- Identify top revenue-driving products or services
- Prioritize quality improvement initiatives
- Optimize sales and marketing strategies
- Reduce inefficiencies by focusing on the vital few factors
- Support executive decision-making with clear, data-backed insights
By embedding Pareto Charts into a Power BI dashboard, businesses gain real-time visibility into performance metrics that drive growth.

Business Applications of Pareto Analysis with Power BI
The Pareto Chart in Power BI is widely applicable across industries:
- Retail: Identify which 20% of products generate 80% of sales.
- Manufacturing: Pinpoint top defect causes and optimize production quality.
- Financial Services: Discover which client segments deliver the most profitability.
- Customer Analytics: Focus retention efforts on the most valuable customers.
- Supply Chain & Logistics: Prioritize suppliers and streamline operations.
With the help of Power BI consulting services, businesses can automate Pareto Analysis to make smarter, faster, and more profitable decisions.
According to the Pareto Principle, 80% of outcomes often come from just 20% of causes. By leveraging Pareto Charts in Power BI, businesses can uncover which products, services, or processes drive the most value. Whether it’s identifying top-performing categories, reducing costs, or boosting efficiency, this powerful visualization empowers organizations to focus on what truly matters.

FAQs About Pareto Chart in Power BI
Q1: What is a Pareto Chart used for in Power BI?
A Pareto Chart helps visualize the most important factors contributing to an outcome, based on the 80/20 rule. In Power BI, it is commonly used to analyze sales performance, product contribution, and business efficiency.
Q2: How do I calculate the cumulative percentage in Power BI for a Pareto Chart?
You can calculate a cumulative percentage using a DAX measure with SUMX and DIVIDE. This allows you to show the cumulative contribution of each category in relation to the total.
Q3: Can I create an 80% threshold line in a Power BI Pareto Chart?
Yes. You can add a static line measure (line = 0.8) to visualize the point at which 80% of results are achieved.
Q4: What industries benefit the most from Pareto Charts in Power BI?
Industries like retail, manufacturing, supply chain, finance, and healthcare benefit significantly, as they can identify key products, customers, or processes driving most of the impact.
Q5: How does Pareto Analysis improve decision-making in businesses?
Pareto Analysis allows organizations to prioritize resources by focusing on the most impactful areas, improving operational efficiency, reducing waste, and boosting profitability.
