Understanding CAGR vs. Simple Returns?
A **Simple Return** measures the total percentage gain or loss of an investment from start to finish. However, it does not account for time. **CAGR (Compound Annual Growth Rate)** represents the annualized rate of return required for an investment to grow from its initial balance to its ending balance, assuming profits compounding annually. CAGR makes it easy to compare investments of different durations.
Why Annualized Returns Matter for Long-Term Planning?
Looking only at absolute gains can be misleading. A $10,000 profit made in one year is far superior to a $10,000 profit made over ten years. Annualizing your returns via CAGR normalizes the time factor, allowing you to compare your portfolio performance against benchmarks like the S&P 500.
