Online Waterfall Bar Chart Tool
Free online waterfall bar chart maker. Show how positive and negative changes build toward a final total, customize colors, and preview the result instantly.
Why It Works
A waterfall bar chart makes each increase and decrease visible, so people can see how a starting value turns into a final total without reading a long financial table.
Break profit, cost, budget, or performance changes into clear step-by-step contributions.
Highlight which items added value, which items reduced it, and how large each impact was.
Use one compact chart to explain net change in reports, finance reviews, and operating summaries.
Product Highlights
Update the step names and positive or negative values directly in the built-in table without leaving the chart workflow.
The preview recalculates each bridge step and the final total as soon as you change the data.
Adjust the chart title and total labels.
Show or hide value labels, legend, background grid, and connector lines depending on how much explanation your audience needs.
