How this S&P 500 return calculator works
This calculator uses historical S&P 500 total return data (price appreciation + dividends reinvested) to show the annualised return for any historical start-to-end period, and projects hypothetical future returns based on your chosen growth assumption.
- Historical data sourced from publicly available S&P 500 total return indices (dividends reinvested).
- CAGR = (end value ÷ start value)^(1/years) − 1.
- Inflation-adjusted ('real') return is computed by deflating nominal returns by CPI for the same period.
- For projections, apply a user-defined annual return assumption to a lump-sum or series of contributions.
Past performance of the S&P 500 does not guarantee future results. Index investing involves market risk; values can and do decline. This tool is educational.
