Why Index Investors Need a Compound Interest Calculator?
Compound interest is often called the "eighth wonder of the world". For index investors, it is the primary engine of wealth creation. Unlike active trading which relies on timing the market, index investing relies on time in the market.
Use this tool to plan your path to Financial Independence (FIRE). Whether you are investing in the S&P 500 (VOO), Total World Stock (VT), or a balanced portfolio, understanding the relationship between your Principal, Monthly Contribution, and Time Horizon is crucial.
How to Estimate Your Annual Return?
When using the calculator, it's important to use realistic return expectations based on historical data:
- Conservative (5-6%): A balanced portfolio of stocks and bonds (e.g., 60/40 split).
- Market Average (7-8%): The historical inflation-adjusted return of the S&P 500 over the last century.
- Aggressive (10%+): 100% Equity portfolios in high-growth periods (riskier).
