Stock market returns since 1979
If you invested $100 in the S&P 500 at the beginning of 1979, you would have about $17,517.11 at the end of 2024, assuming you reinvested all dividends. This is a return on investment of 17,417.11%, or 12.05% per year.
This lump-sum investment beats inflation during this period for an inflation-adjusted return of about 3,928.78% cumulatively, or 8.48% per year.
If you used dollar-cost averaging (monthly) instead of a lump-sum investment, you'd have $15,105.82.

Adjusting stock market return for inflation
The nominal return on investment of $100 is $17,417.11, or 17,417.11%. This means by 2024 you would have $17,517.11 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 1979 was 72.600 and the CPI in 2024 was 315.664.
The ratio between these CPIs describes how relative buying power of a dollar has changed over 45 years.
Adjusted for inflation, the $17,517.11 nominal end value of the original $100 investment would have a real return of roughly $3,928.78 in 1979 dollars. This means the inflation-adjusted return is 3,928.78% as opposed to the original 17,417.11%.

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 1979. This would result in a final amount of $15,105.82, including dividend reinvestments. In this particular case, dollar-cost average returns are less than the returns of a lump-sum investment (which ends with $17,517.11).
