Methodology

SPDR S&P 500 ETF (SPY, daily adjusted close, Yahoo Finance) and the CPI-U headline index (CPIAUCSL, monthly, seasonally adjusted, FRED), both rebased to 100 at their shared start. SPY is averaged to monthly to match CPI. The spread between the lines is the real (inflation-adjusted) equity return over the window. SPY's adjusted close reflects the S&P 500's total return (price appreciation plus dividends).
