Tracking how profits flow between periods can be challenging. A waterfall chart could be the solution you’re looking for.
These visual tools tell the story of changing values over time and excel at financial analysis. Waterfall charts act as financial storytellers that start with one value and show each change, positive or negative, until reaching the final number. They bring clarity to complex data sets and make financial statements easier to grasp.
Business professionals can quickly spot performance trends and identify what drives profitability with these charts. What makes waterfall charts special? Finance professionals often use these charts (also called bridge charts) because they show financial scenarios clearly. The best time to use waterfall visualization comes when you need to show cash flow, income statements, or analyze variances.
Traditional charts often create confusion when showing sequential financial changes. A waterfall bar chart shows how each element affects your overall financial metrics. This piece breaks down everything about creating and using these powerful visualization tools.
Zebra BI offers some excellent examples for those seeking advanced visualization options.

Start with the Problem: Why Traditional Charts Fall Short
Traditional data visualizations conceal as much as they reveal. Simple chart types work well with basic data, but they often fail to represent complex financial changes effectively.
The Limitations Of Bar And Line Charts
Bar charts fall short when they need to display sequential changes. These charts cannot show cumulative effects or how elements build upon each other. Cost savings shown as just another bar make readers lose sight of how savings offset unexpected costs. The charts struggle with comparisons without a common baseline, which makes it hard to determine which factors affect outcomes more.
Line graphs excel at tracking trends over time and highlighting patterns. They leave a vital gap because they don’t explain why those patterns occur. Readers can see a dip in March or spike in June but not the reason behind it. These charts emphasize direction rather than cause and effect.
Both chart types also struggle with:
- Showing positive and negative contributions in context with each other
- Explaining the experience between the start and end values
- Showing how intermediate changes affect final results
“Showing the data requires that graphical elements have a consistent relationship with the underlying numbers,” notes Edward Tufte. All the same, approximately 12% of charts in one study had fatal proportionality flaws. These errors often mask data relationships.
Why Waterfall Bar Charts Offer Better Insight
Waterfall charts excel precisely where traditional visualizations fall short. The left-to-right progression matches reading patterns that start with a baseline and show how each change contributes to the final result.
Waterfall charts provide three key advantages: speed to insight, context, and narrative. Tables require mental math, but waterfall charts are a great way to get instant visual cues. A big red bar immediately signals that specific factor caused a major drop.
These charts also place positive and negative contributions in context. Users can spot if massive gains in one area were offset by losses elsewhere.
Bar charts answer “What is the value?” The difference lies in how waterfall charts answer “How did we get to this value?” This makes them the finance professionals’ top choice to understand profit dynamics.
Understanding the Waterfall Chart Structure
Waterfall charts have a distinctive structure that sets them apart in the data visualization world. Understanding their anatomy helps reveal how they work.
What Is A Waterfall Chart?
A waterfall chart shows how positive and negative values affect an original amount and lead to a final total. These visually striking charts make complex financial changes clear by displaying their cumulative effects.
People know them by various names – cascade charts, bridge charts, flying bricks charts, and Mario charts because they look like floating bricks in Nintendo games. McKinsey & Company reportedly created these charts that became essential tools in finance.
How Floating Bars Represent Change
The unique power of waterfall charts comes from their “floating” columns. Standard bar charts start each column at zero, but waterfall charts create a visual story:
- The baseline connects to the first and last columns that show the starting value and final total
- The intermediate columns float and display only incremental changes
- Each bar starts where the previous column ended
- Positive values rise upward from the previous point
- Negative values drop downward to show losses
This floating design creates a distinctive waterfall or cascade effect that becomes particularly noticeable with sequential negative values. The structure clearly shows how individual components add up to the running total.
The Role Of Color And Connectors
Colors play a crucial role in these charts. Different shades typically indicate:
- Positive values (often green or blue)
- Negative values (usually red or orange)
- Total columns (distinct from intermediate values)
Colors serve a functional purpose rather than just decoration. One expert advises: “Don’t turn your waterfall chart into a rainbow”. Smart color choices help clarify numerical meaning.
Connector lines play an important role in making waterfall charts easy to follow. By linking the corners of each column, they guide the viewer’s eye along a clear visual path and show how values build on one another.
Without these connections, floating columns would be harder to interpret. Zebra BI visualizations demonstrate how this thoughtful design makes profit and loss movements much easier to understand at a glance.
Using Waterfall Charts to Tell Financial Stories
Waterfall charts make financial storytelling easier to grasp. These visual tools turn complex numbers into simple stories that everyone can understand.
Waterfall Chart Example: Income Statement Breakdown
Waterfall charts turn confusing P&L statement tables into clear visual stories. A chart can show operating margins dropping from 15% to 3% in a quarter. The chart reveals product recall costs, inventory write-downs, and lower gross income as the key reasons. This way of presenting data makes financial effects clear to people outside finance too.
Visualizing Cash Flow And Revenue Shifts
Your final cash position becomes clearer through waterfall charts that show inflows and outflows. These charts display customer payments along with major expenses like supplier costs and tax bills. Teams can forecast better and prepare for seasonal changes by seeing available liquidity clearly.
Forecasting With Partial-Year Data
Combining actual and projected data in one view proves particularly useful. Picture a chart with January-August actual sales in blue next to September-December forecasts in pink. Teams can see expected performance for the whole period quickly. These visuals help replace guesswork with solid planning.
Explaining Variance In Budget Reports
Waterfall charts make budget vs. actual analysis straightforward. They highlight significant variances immediately. Extra funds from government grants or investment returns explain positive differences. The charts also show shortfalls in corporate donations or taxpayer revenue clearly, which leads to faster fixes. Zebra BI tools can help dig deeper into what really changes performance.
Tools and Tips to Build Better Waterfall Charts
Beautiful waterfall charts are easy to create without advanced design skills. Modern tools help beginners build these visualizations with ease.
Creating Charts In Excel And Google Sheets
Excel made waterfall charts much simpler in 2016. These charts were hard to create before that time.
Excel now comes with built-in features:
- Prepare your data with categories and values (keep costs as negative numbers)
- Select your data range, go to the Insert tab, click the waterfall chart icon
- Right-click on the total bars and select “Set as Total”
Google Sheets makes it just as easy:
- Create two columns (categories and amounts)
- Highlight your data and select Insert > Chart
- Choose Waterfall from the chart type dropdown
- Find customization options in the Chart editor
Using PowerPoint for Presentations
You can create waterfall charts directly in PowerPoint or bring them from Excel:
- Go to Insert > Chart
- Select Waterfall from the chart options
- Input your data in the spreadsheet pop-up
Your Excel chart can be copied and pasted into your slide. PowerPoint keeps the formatting while staying connected to the source data.
Best Practices For Color And Layout
Colors serve a purpose beyond decoration:
- Start/end totals: Neutral color (dark gray/blue)
- Increases: Green or blue
- Decreases: Red or orange (blue/orange works better for colorblind users)
A clear chart needs:
- Fewer steps (10-15 columns maximum)
- Clear data labels right on bars
- Logical groups for complex data
- Connector lines between columns
Avoiding Common Design Mistakes
Watch for these mistakes:
- Mixed-up colors for increases and decreases
- Too many columns that create a mess
- Missing labels for subtotals or totals
- Different scales in related charts
- Charts that don’t start from zero
- Waterfall charts used with non-cumulative data
Conclusion
Waterfall charts turn complex financial data into clear stories that drive action. These visual tools show sequential changes better than regular charts. They give quick visual signals about what drives your financial performance, from unexpected costs eating profits to new revenue streams improving your bottom line.
The structure and real-world uses of these charts explain why finance professionals depend on them. They work best with income statements, cash flow tracking, and budget variance analysis. The floating bars and smart color choices create a user-friendly view that non-financial team members understand quickly.
Making these charts is not complicated anymore. Popular software platforms include waterfall chart features that need minimal setup. All the same, smart color choices, limited columns, and clear labels will make your charts more effective. Users who need more than simple tools should check out Zebra BI for its strong customization options.
Want to change how you show financial data? Try a simple waterfall chart in your next profit analysis or budget review. Your audience will ask fewer questions and understand the information faster. Waterfall charts do more than show numbers; they reveal the story behind them. This storytelling ability makes the difference when decisions depend on understanding financial flows.
