Stock market returns since 2019
If you invested $100 in the S&P 500 at the beginning of 2019, you would have about $230.77 at the end of 2024, assuming you reinvested all dividends. This is a return on investment of 130.77%, or 16.69% per year.
This lump-sum investment beats inflation during this period for an inflation-adjusted return of about 86.90% cumulatively, or 12.24% per year.
If you used dollar-cost averaging (monthly) instead of a lump-sum investment, you'd have $194.09.
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.

Adjusting stock market return for inflation
The nominal return on investment of $100 is $130.77, or 130.77%. This means by 2024 you would have $230.77 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 2019 was 255.658 and the CPI in 2024 was 315.664.
The ratio between these CPIs describes how relative buying power of a dollar has changed over 5 years.
Adjusted for inflation, the $230.77 nominal end value of the original $100 investment would have a real return of roughly $86.90 in 2019 dollars. This means the inflation-adjusted return is 86.90% as opposed to the original 130.77%.

Full monthly data
The table below shows the full dataset pertaining to a $100 investment, including gains and losses over the 65-month period between 2019 and 2024.
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 2019. This would result in a final amount of $194.09, including dividend reinvestments. In this particular case, dollar-cost average returns are less than the returns of a lump-sum investment (which ends with $230.77).
