Free Sankey Diagram Maker for Budgeting (2026): Visualize Cash Flow in Minutes
Spreadsheets show you numbers. A Sankey diagram shows you flow. With PopaDex, you can build a free Sankey diagram for your budget in minutes and instantly see where every dollar goes.
What Is a Budget Sankey Diagram?
A Sankey diagram is a flow visualization where the width of each band represents value. In a personal finance context, it maps income → categories → expenses so you can spot the biggest leaks fast. If housing eats half your take-home pay, the diagram makes it impossible to miss.
