Investment Return Calculator

Accurately measuring investment returns goes beyond simply comparing beginning and ending balances. Total return includes price appreciation, dividends, interest, and distributions, giving you the complete picture. Annualized return (CAGR) converts total return into a consistent yearly rate that accounts for compounding, making it the standard metric for comparing investments across different time periods and asset classes.

Real Returns vs Nominal Returns

Nominal returns are the raw numbers before inflation. Real returns adjust for inflation and represent the actual change in your purchasing power. Over long periods, the distinction is critical: the S&P 500 has averaged roughly 10% nominal returns but only about 7% in real terms. When planning for goals decades away, always think in real returns to avoid overestimating your future purchasing power. A portfolio that earns 8% when inflation runs 3% is truly growing at only 5% in terms of what your money can buy.

The Importance of Benchmarking

Benchmarking your returns against a relevant index answers the most important question in investing: am I doing better than a simple index fund? The S&P 500 is the most common benchmark, returning approximately 10% annually over the long term. If your actively managed portfolio consistently underperforms this benchmark after accounting for fees, you may be better served by low-cost index funds. Compare over meaningful periods of at least 3-5 years, since short-term outperformance is often due to luck rather than skill.
