Investing $ 100 monthly in S&P 500 over 10 years, what would be a realistic total Final Net Worth (After Costs) for this position ?

For the last 10 years the S&P 500 has performed better than before for several reasons. Low interest rates and monetary policy resulted in high liquidity and record inflows into the stock market. Tech, growth and some Big companies were the best performing sectors and drove the S&P 500 to new highs. The high volatility lately shows how nervous the market is. The market is trading expectations and most of the times the outlook a company gives has more effect on the stock price than the numbers it reported because growth rates are projected for the future. My question is now what your expectations are for the next 10 years. ( 12month with $100 over 10 years is a $12k deposit, serves only as an example to be able to compare the expectations better)
