$50 Invested Monthly for 20 Years in the S&P 500 Index

This chart represents the growth of $50 invested each month over 20 years from 2004 to 2024. This is a conservative estimate, accounting for ETF fees and taxes that would eat at your gains. We also assumed an unlikely scenario where you stayed at the $50 level each month, despite inflation and other changes in your life, though we assumed you prudently reinvested your dividends.

Effects of inflation, taxes, and fees, with some adjustments, taken from Robert Schiller's widely used figures (including historic dividends) on index investing, along with the CPI at the U.S. Bureau of Labor Statistics and historical data from TradingView. We have also used historic ETF fees taken from the Investment Company Institute for the average of passive index funds, and assumed a 15% capital gains tax rate.
