Adjusting stock market return for inflation

The nominal return on investment of $100 is $77,087.26, or 77,087.26%. This means by 2022 you would have $77,187.26 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 1955 was 26.800 and the CPI in 2022 was 296.311.

The ratio between these CPIs describes how relative buying power of a dollar has changed over 67 years.

Adjusted for inflation, the $77,187.26 nominal end value of the original $100 investment would have a real value of roughly $6,881.24 in 1955 dollars. This means the inflation-adjusted return is 6,881.24% as opposed to the original 77,087.26%.

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 1955. This would result in a final amount of $61,276.29, including dividend reinvestments. In this particular case, dollar-cost average returns are less than the returns of a lump-sum investment (which ends with $77,187.26).
