Methodology & Data Sources
This historical dataset compiles S&P 500 performance metrics from multiple authoritative sources to provide a complete picture of market returns since 1928. The data represents calendar year performance (January 1 to December 31).
Data Sources
- S&P 500 Total Returns: Sourced from Aswath Damodaran's NYU Stern historical dataset, which includes reinvested dividends.
- Price Returns & Inflation: Compiled using data from the Robert Shiller / Cowles Commission dataset (via public GitHub datasets) and recent data from Yahoo Finance.
- Inflation Rate: Calculated based on Consumer Price Index (CPI) changes from December of the prior year to December of the current year.
Calculations
The Real Return is calculated using the exact formula: ((1 + Total Return) / (1 + Inflation)) - 1, rather than simply subtracting inflation from the total return, to ensure mathematical accuracy over time.
