What CAGR Measures

CAGR converts uneven portfolio growth into one steady annual rate. If a portfolio rises and falls over several years, CAGR answers: “what annual return would create the same ending balance if growth happened smoothly?”

Why CAGR Matters for FIRE

FIRE plans depend heavily on long-term compounding. A higher CAGR shortens the time needed to reach financial independence; a lower CAGR means more savings, more time, or a smaller monthly allowance. That is why calculator assumptions should be tested instead of treated as promises.

How to Use This CAGR Calculator

  1. Enter your initial deposit and monthly savings.
  2. Set the number of years you want to project.
  3. Adjust CAGR to compare conservative, baseline, and optimistic assumptions.
  4. Read the stacked bars to separate principal from deposit interest and savings interest.
