Understanding Your Investment Results
Compound Interest Power
Your investment grows exponentially due to compound interest - earning returns on both your contributions and previous returns. The longer you invest, the more powerful this effect becomes.
Inflation Impact
The "Real Value" shows your purchasing power after accounting for inflation. This helps you understand what your future money will actually be worth in today's dollars.
Regular Contributions
Consistent monthly contributions through dollar-cost averaging can help reduce risk and take advantage of market volatility. Small increases in monthly contributions can lead to significant long-term growth.
Risk Considerations
These projections assume consistent returns, but real markets fluctuate. Diversification and a long-term perspective can help manage investment risk.
