Understanding Your S&P 500 Rate of Return
The Standard & Poor's 500 Index (S&P 500) is the primary benchmark for the U.S. stock market. Calculating your personal rate of return against this index helps you understand if your investment strategy is outperforming the broader market.
Total Return vs. Annualized Return (CAGR)
While Total Return tells you the raw percentage growth of your money from the start date to the end date, Annualized Return (often called the Compound Annual Growth Rate or CAGR) provides the smoothed annual growth rate. This is the most accurate way to compare different investments that were held for different periods of time.
How to Use This Calculator
- Initial Investment: Enter the original amount of capital you put into an S&P 500 index fund or ETF (like SPY or VOO).
- Final Value: Enter the current market value of that same holding, including reinvested dividends.
- Duration: The total number of years you have held the asset.
Historical S&P 500 Context
Historically, the S&P 500 has delivered an average annual return of approximately 10% before inflation. However, this varies significantly decade by decade. By using this calculator, you can see how your specific entry and exit points compare to long-term averages.
The Power of Compounding Example
If you invested $10,000 and it grew to $25,937 over 10 years, your total return is 159.37%. However, your Annualized Return (CAGR) is 10%. This illustrates how consistent 10% gains compound to more than double your money in a decade.
