Create professional waterfall charts to visualize how initial values are affected by positive and negative changes. Perfect for financial analysis, profit/loss breakdowns, and showing cumulative effects.
Data Format & Order Tips
Order matters! Waterfall charts show cumulative flow, so arrange your data logically:
- "starting"/"initial" values come first
- "positive"/"negative" changes come in the middle (in logical sequence)
- "ending"/"final"/"total" values come last
Include a type column with these values to properly categorize your data points. Starting and ending values appear as full bars, while others show as floating changes.

Waterfall Charts: Definition, Uses, and Interpretation
What is a Waterfall Chart?
A waterfall chart is a data visualization that shows how an initial value is affected by a series of positive or negative changes. The chart resembles a waterfall, with floating bars representing incremental changes that lead to a final cumulative value. Each bar starts where the previous one ended, creating a cascading effect.
Common Uses of Waterfall Charts
- Financial analysis: profit and loss statements, revenue breakdowns
- Budget variance analysis showing actual vs planned spending
- Cash flow analysis tracking inflows and outflows
- Inventory analysis showing stock changes over time
- Employee headcount changes (hires, departures, transfers)
- Project cost analysis breaking down different expense categories
Interpreting Waterfall Charts
When analyzing a waterfall chart, consider the following:
- Starting and ending values are typically shown as full bars from zero
- Positive changes are usually shown in green and extend upward
- Negative changes are typically shown in red and extend downward
- The cumulative effect shows the net impact of all changes
- Connector lines help visualize the flow from one category to the next
Best Practices for Waterfall Charts
- Use consistent color coding (green for positive, red for negative)
- Order categories logically to tell a clear story
- Include data labels to show exact values
- Use connector lines to emphasize the cumulative nature of changes
- Limit the number of categories to maintain readability (typically 5-10)
- Clearly distinguish between starting/ending totals and incremental changes
- Include a descriptive title that explains what the chart represents
