In today’s data-driven world, businesses rely heavily on visualization tools to understand their data and make better decisions.
One of the most popular tools used by analysts is Tableau, which helps in converting raw data into meaningful insights.
Among many visualization techniques available in Tableau, the Funnel Chart is widely used to analyze step-by-step processes such as sales pipelines, customer journeys, and conversion flows.
A funnel chart is especially useful for tracking how data flows through different stages and identifying where the drop-off occurs.
For example, in a sales process, you may start with 1,000 leads, but only 100 become customers. A funnel chart helps you clearly visualize this reduction in numbers across stages. This makes it easier to understand performance and improve business strategies.
In this article, we will explore everything about the Tableau Funnel Chart. You will learn what it is, why it is used, how to create it in Tableau, real-time use cases, advantages, limitations, and best practices.
What is a Funnel Chart in Tableau?
A Funnel Chart is a type of data visualization that represents how values decrease across different stages of a process.
It is called a funnel chart because it resembles a funnel—wide at the top and narrow at the bottom. The top part represents the largest value, and each subsequent stage becomes smaller, showing a reduction in data.
In Tableau, a funnel chart is not available as a default chart type. Instead, it is created using bar charts or dual-axis techniques and customized to look like a funnel.
The main purpose of a funnel chart is to:
- Show the flow of data through stages
- Identify drop-offs between stages
- Analyze conversion rates
- Improve process efficiency
For example, a typical sales funnel includes:
- Leads
- Qualified Leads
- Opportunities
- Closed Deals
At each stage, the number of customers decreases, as shown in a funnel chart.

Why Use Funnel Chart in Tableau?
Funnel charts are very useful in business analytics because they provide a clear and simple way to understand complex processes. Instead of looking at tables or raw numbers, you can visually see where the biggest losses are happening.
Here are some important reasons to use funnel charts:
- Identify Drop-Off Points
- A funnel chart helps you identify where users or customers are dropping out of the process. For example, if many users drop off after the “Add to Cart” stage, you know where to improve.
- Measure Conversion Rates
- It shows how many users move from one stage to another, helping you calculate conversion percentages.
- Easy to Understand
- The funnel shape makes it very easy for anyone (even non-technical users) to quickly understand the data.
- Better Decision Making
- By analyzing the funnel, businesses can improve strategies and increase efficiency.
Advantages of Funnel Chart
- Easy to understand
- Highlights drop-offs clearly
- Useful for business analysis
- Improves decision-making
- Works well with dashboards
Create a Funnel Chart in Tableau
In Tableau, there is no built-in option to create a Funnel chart. To create a funnel chart, we need to customize the bar chart to display it in a funnel-like format.
In this example, I will create a funnel chart to display the share of products across various segments, such as Home Office, Corporate, and Consumer. The data source for this funnel chart will be the sample Superstore data from Tableau.
Follow the steps below to create a funnel chart in Tableau.
- Drag the SUM(Sales) to the Rows shelf.

- After this, drag the Segment field to the Color card in the Marks section.
- To display the size of each segment in increasing order, drag the SUM(Sales) to the Size card in the Marks section.

- To reorder the categories and make them appear like a funnel, click the Sort button in the toolbar.
As a result, the bar chart will be displayed in a funnel format.
- To add the label for the sales amount and the product category, drag the SUM(Sales) and Category to the Label card in the Marks section.
Now, in the funnel chart, we see the contribution of each product category to the Sales. This way, we can create a funnel chart in Tableau using the steps above.

Create a Funnel Chart in Tableau Using Dual Axis
In this method, we will create a horizontal bar chart with a dual axis to display it as a funnel chart.
In this, we will display the share of the product subcategory in the total sales. The funnel chart will be stacked from the least selling product to the product with the maximum sales.
Follow the steps below to create a Funnel chart using the dual-axis bar.
- Drag the Sum(Sales) to the Columns and Sub Category to the Rows.
- Add SUM(Sales) again to the Columns and edit its value as -SUM(Sales). It will duplicate a negative horizontal bar for the sales of the product’s subcategory.
- Set the Sales for Sub-Category in ascending order. This will combine both charts and display them as a funnel chart.

- To show the flow of Sales from minimum to maximum, drag Sales to the Color card in the Marks section.
Here, we need to add sales to the color section of both the horizontal charts.
- To show the Sales of each sub-category, drag the Sales to the Label card in the Marks section.
Here, we also don’t need the negative axis to be displayed in the chart. To remove it, right-click on the x-axis and uncheck Show Header.
With this, we can see that the data is being displayed as a funnel chart.

This way, using two horizontal charts on dual axes, we can create a funnel chart in Tableau by following the steps above.
Funnel Chart vs Bar Chart
| Feature | Funnel Chart | Bar Chart |
|---|---|---|
| Shape | Funnel | Rectangular |
| Purpose | Show drop-off | Compare values |
| Complexity | Medium | Easy |
| Use Case | Process stages | General comparison |
