If you invested $100 in the S&P 500 at the beginning of 1989, you would have about $2,641.24 at the end of 2022, assuming you reinvested all dividends. This is a return on investment of 2,541.24%, or 10.16% per year.
This lump-sum investment beats inflation during this period for an inflation-adjusted return of about 1,019.11% cumulatively, or 7.40% per year.
If you used dollar-cost averaging (monthly) instead of a lump-sum investment, you'd have $2,227.70.
The graph below shows the performance of $100 over time if invested in an S&P 500 index fund. The returns assume that all dividends are automatically reinvested.
The nominal return on investment of $100 is $2,541.24, or 2,541.24%. This means by 2022 you would have $2,641.24 in your pocket.
However, it's important to take into account the effect of inflation when considering an investment and especially a long-term investment. You can convert S&P returns to their real (inflation-adjusted) value using an inflation calculation based on the U.S. Bureau of Labor Statistics Consumer Price Index (CPI).
In the case of the returns described above, the CPI in 1989 was 124.000 and the CPI in 2022 was 292.656.
The ratio between these CPIs describes how relative buying power of a dollar has changed over 33 years.
Adjusted for inflation, the $2,641.24 nominal end value of the original $100 investment would have a real return of roughly $1,019.11 in 1989 dollars. This means the inflation-adjusted return is 1,019.11% as opposed to the original 2,541.24%.
The table below shows the full dataset pertaining to a $100 investment, including gains and losses over the 406-month period between 1989 and 2022.
Note that data shown is the monthly average closing price. Returns include dividends.

Remember, returns are based on the average closing price across the entire month. Some losses are offset by dividend returns.
Dollar-cost averaging
Dollar-cost averaging is an alternative to investing the full lump-sum of $100.00 up-front. Instead, the capital is invested over a period of time.
Consider a strategy in which $100.00 was invested in the S&P 500 over a period of no more than 24 months beginning in 1989. This would result in a final amount of $2,227.70, including dividend reinvestments. In this particular case, dollar-cost average returns are less than the returns of a lump-sum investment (which ends with $2,641.24).

Data Sources
The information on this page is derived from Robert Shiller's book, Irrational Exuberance and the accompanying dataset, as well as the U.S. Bureau of Labor Statistics' monthly CPI logs.
Note that S&P index value for the current quarter is based on a moving average of closing prices, per Robert Shiller's methodology. The inflation data used is based on annual CPI averages.
Ian Webster is an engineer and data expert based in San Mateo, California. He has worked for Google, NASA, and consulted for governments around the world on data pipelines and data analysis.

Ian earned his degree in Computer Science from Dartmouth College.
