Easy Tech TutsHow to Use Waterfall Chart Visualization in Power BI - Visualize Gains and Losses Easily 2026
By Impran M N
Some financial stories are best told step by step, showing exactly where value was added or lost along the way, and that's precisely what a waterfall chart does well. This guide covers how to build one in Power BI from scratch, including importing data and setting up the visual. It's aimed at analysts and decision-makers who need to communicate financial trends clearly during reviews or planning meetings.
01Import your data
Bring in the dataset that contains the categories and values you want to break down, such as budget line items or monthly financial changes.
02Create your first waterfall chart
Select the Waterfall Chart visual from the visualizations pane, then assign your category field and the value field that represents each increment.
03Define metrics for gains and losses
Make sure your value field clearly represents positive and negative changes, since the chart relies on these signs to color and stack each step correctly.
04Explore key features and customization
Adjust colors for increases and decreases, add a total column, and format labels so the chart is easy to interpret at a glance.
05Apply it to real use cases
Use the waterfall chart for scenarios like showing how revenue moved from a starting point to an ending point across several contributing factors.
Frequently asked questions
What kind of data works best for a waterfall chart?
Data with clear sequential categories and both positive and negative values, such as budget variances or monthly profit changes, works best for this visual.
Can I show a running total alongside individual changes?
Yes, the waterfall chart is specifically designed to show both the individual steps and how they accumulate toward a final total.
How do I distinguish gains from losses visually?
The visual automatically colors increases and decreases differently by default, and these colors can be customized in the formatting pane.
Is a waterfall chart suitable for non-financial data?
Yes, while it's common in finance, it works for any scenario involving sequential increases and decreases, such as inventory changes or project scope adjustments.
