How to read this investment calculator

This tool uses a steady annual return and monthly contributions to estimate future balance. Real portfolios move up and down; long-term averages are not what you experience every year.

The chart splits your ending balance into three parts: your original lump sum, everything you added later, and the portion created by compounding. The schedule shows deposits, interest, and balance step by step.

Use it to build intuition — for example, how starting earlier or increasing contributions changes the curve — then learn how to apply those ideas with context in the course.
