Calculate the potential returns of your S&P 500 investments from 1928 to 2025. See how your investment would have grown over time.
Explore the leading companies that make up the S&P 500 index, representing the largest U.S. publicly traded corporations.
The S&P 500 is a stock market index tracking the performance of 500 large companies listed on U.S. stock exchanges. It's considered one of the best gauges of large-cap U.S. equities.
Since its inception, the S&P 500 has delivered an average annual return of approximately 10%. However, returns can vary significantly year by year.
Many investors choose the S&P 500 for long-term investment through index funds or ETFs, benefiting from broad market exposure and historically consistent returns.
The calculator uses historical S&P 500 data to compute both nominal returns and inflation-adjusted values, including dividend reinvestment.
1928 marks the beginning of reliable, comprehensive S&P 500 historical data, providing almost a century of market performance information.
Historical return data is based on monthly stock price, dividends, and earnings data from the S&P 500 index starting from 1928. The calculations include dividend reinvestment and are adjusted for inflation using CPI-U (Consumer Price Index-All Urban Consumers) data.
An index is a hypothetical portfolio of securities representing a particular market segment. Indices are not available for direct investment; therefore, their performance does not reflect the expenses associated with managing an actual portfolio.
