Investment Return Calculator

About This Investment Return Calculator

Investment return analysis helps compare options on an apples-to-apples basis. CAGR (Compound Annual Growth Rate) smooths out volatility to show consistent year-over-year growth. The S&P 500 has historically averaged 10% annual return before inflation. Always compare investments on an after-fee, after-tax, inflation-adjusted basis for the truest picture.

How the Calculation Works

CAGR = (Ending Value / Beginning Value)^(1/years) − 1

Making the Most of This Tool

Financial calculators are most useful when you run multiple scenarios. Try adjusting the rate and time period to understand how small changes in return rate or investment duration affect outcomes. The power of compound growth means starting earlier almost always outweighs starting with a larger amount.

Important Considerations

All financial projections involve assumptions that may not hold in reality. Market returns fluctuate, interest rates change, and individual circumstances vary. Use this calculator as a planning tool to understand ranges and general direction, not as a guarantee of specific outcomes.
