What is Power BI Percent of Total?

Definition: The percentage of the total in Power BI is used to express the proportion of a value compared to the total of the values given. It’s widely used to figure out the contribution of each item to the overall total. Results from this calculation are usually expressed as a percentage. It’s used to visualize relative importance (or distribution) within a Power BI dataset.

Why Do We Calculate the Percentage of the Total in Power BI?

Calculating the percentage of the total in Power BI is essential for several reasons:

• Relative Comparison: It helps in comparing individual values against the total value. This way, users will gain insights into the contribution (or relative importance) of an individual value to the whole.
• Visualization: The percentage of the total is much easier to visually interpret in graphs and charts. Imagine slicing a pie to see which piece is the biggest percentage let you quickly spot the significant portions. This clarity helps you interpret graphs and charts more effectively, providing a clear grasp of value distribution within the dataset. It’s like turning raw numbers into a visual story, making complex data intuitive and accessible. With visual storytelling, you can quickly and effectively communicate insights, making data not just understandable but engaging and memorable.
• Identifying Trends and Patterns: Trend analysis enhances the identification of outliers or patterns by spotlighting values with a significant impact on the total. It’s like having a magnifying glass that highlights the most impactful data points, helping you see trends and anomalies that might otherwise go unnoticed. By focusing on these key values, trend analysis turns data into a vivid narrative, making it easier to uncover insights and patterns that drive meaningful decisions.
• Decision Making: The Percentage of the total in Power BI indicates the areas (or items) with the most significant impact on the entire performance. And that helps in making data-driven decisions.
• Benchmarking: By comparing the percentage contribution of different categories (or items), Power BI percent of the total helps benchmark against industry standards (or targets).

How Do You Calculate the Percentage of Total in Power BI?

Let’s say there’s a table in Power BI named my_data, the table contains points scored by basketball players on multiple teams.

There’s the option of adding a new column to show how each value in the Points column represents a percentage of the total values in the Points column. To do that, click the “Table Tools” tab. From the options that come up, click the “New column” icon.

After that, input the formula below into the formula bar:

A new column named “Percent of Team Total” will be created. The column shows you how each value in the “Points” column represents a percentage of the total values in the Points column for each team.

To showcase the values as percentages, click the dropdown arrow next to the Format option. After that, click Percentage.

Each of the values in the Percent of Team Total column will be showcased as percentages.

Here’s an easy way of interpreting the values in the Percent of Team Total column:

• The first Mavs player scored 25.88% of all points scored by the Mavs.
• The second Mavs player scored 16.47% of all points scored by the Mavs.
• The third Mavs player scored 22.35% of all points scored by the Mavs.
• The fourth Mavs player scored 35.29% of all points scored by the Mavs.

Adding up all the percentages will give a total of 100%.

Total Mavs Points: 25.88% + 16.47% + 22.35% + 35.29% = 100%.

You’ll notice the same pattern in other teams in the table.

How Do You Evaluate the Power BI Percent of Total by Category?

These are the steps to help you evaluate the Power BI percent of total by category:

1. Create the Measure: You can get started by using Data Analysis Expressions (DAX) to create a measure that calculates the total for your desired category. For instance, to calculate the percentage of total sales by product category, you’ll have to create a measure that calculates the total sales for the individual product category.
2. Create a Percentage of Total Measure: To calculate the percentage of total for each category, create another measure using DAX. To do that, you’ll have to divide the total for each category by the overall total across all categories.
3. Visualize the Data: In the realm of Power BI dashboard designs, visualizations like column charts, bar charts, or tables can vividly showcase the percentage of the total by category. Simply drag the category field and the percentage of total measure into your chosen data visualization to bring your data to life. This approach transforms raw figures into a visually engaging story, making it easy to discern how each category contributes to the whole. With thoughtful design, your Power BI dashboards become not just a display of data but a powerful tool for insightful analysis and decision-making.
4. Add Interactivity: Power BI interactive features enable users to explore the data. For instance, you can enable the drill-down feature to allow you to drill down into categories for detailed analysis of your data.
5. Analyze and Interpret: Analyze your data to identify outliers, patterns, or trends using the DAX format. By interpreting the results, you’ll gain insights into the relative contribution of individual categories to the overall total.

The formula below is used for calculating percentage with DAX in Power BI:

Measure for Total Sales:

Total Sales = SUM(Sales[SalesAmount])

Measure for Sales Percentage:

Sales Percentage = DIVIDE(SUM(Sales[SalesAmount]), [Total Sales], 0)

Wrap Up
