How Investment Returns Are Calculated
Your investment growth depends on several important factors.
Initial Investment
This is the amount of money you invest at the beginning. A larger starting balance has greater earning potential over time.
Additional Contributions
Regular monthly or annual contributions can significantly increase your investment value through consistent investing and compound growth.
Annual Rate of Return
Your expected annual return represents the average percentage your investment earns each year. While future performance is never guaranteed, historical averages can be useful for planning.
Investment Time
The longer you remain invested, the greater the opportunity for your money to grow through compound returns.
Compound Growth
As your investment earns returns, those earnings begin generating additional earnings. This compounding effect is one of the most powerful drivers of long-term wealth.
Factors That Affect Investment Returns
Several factors influence how much your investments may grow.
Market Performance
Stock and bond markets fluctuate over time. Investment returns can vary from year to year depending on economic conditions and market performance.
Contribution Amount
Increasing your regular contributions can have a significant impact on your future investment balance.
Investment Strategy
Your investment choices—including stocks, bonds, mutual funds, ETFs, and other assets—will influence your expected rate of return and investment risk.
Investment Time Horizon
Longer investment periods provide more opportunities for compound growth and may help reduce the impact of short-term market fluctuations.

- Invest consistently, regardless of market conditions.
