Sankey Diagrams: Visualizing Money Flow in SavePoint

Numbers in a spreadsheet tell you facts. A Sankey diagram tells you a story. It shows exactly how money flows from your income sources through your spending categories, with the width of each flow representing the amount. Thick streams are where your money is really going. Thin ones? Not so much.

SavePoint includes Sankey diagrams as one of its report types, and once you see your finances visualized this way, you'll understand patterns that raw numbers never quite revealed.

What a Sankey Diagram Shows You

A Sankey diagram traces the path of your money from left to right. On the left side, you have your income sources. On the right side, you have your expenses and savings. The flows between them show exactly where each dollar ends up.

The width of each flow is proportional to the amount. If housing takes 35% of your income, that stream is going to dominate the chart visually. If your gym membership is 0.5%, you'll barely see it. This visual weighting makes it immediately obvious where your money is concentrated.

How to Generate a Sankey Diagram in SavePoint

In SavePoint, navigate to Reports and select the Sankey diagram option. You can generate this report for any time period: a single month, a quarter, or a full year. The annual view often provides the clearest picture since it smooths out month-to-month variations.

What to Look For

The first thing that will jump out is your biggest expense categories. For most people, housing dominates. But you might be surprised by other flows. Food spending (groceries plus dining out combined) often creates a thicker stream than people expect. Same with transportation when you add up the car payment, insurance, gas, and maintenance.

Look for categories where the flow seems disproportionate to the value you're getting. That subscription bundle might look small in dollar terms, but seeing it in proportion to your total spending might prompt a second look.

Using Sankey Diagrams for Budget Planning

One of the most useful applications is comparing your Sankey diagram to your budget goals. If you've committed to saving 20% of your income but your diagram shows only a thin stream going to savings, you have a visual confirmation that your reality doesn't match your intention.

You can also use the diagram to identify reallocation opportunities. Maybe your entertainment spending is larger than your savings flow. Seeing that visually can motivate changes that spreadsheet rows never quite triggered.

Sharing Financial Insights

If you're working toward financial goals with a partner or family, a Sankey diagram can be a powerful communication tool. It's much easier to have a productive conversation about spending when everyone can see the same visual representation. The numbers are objective and proportional, not accusatory.

Sometimes a picture really is worth a thousand transactions.
