The Power of Compound Interest in Investing
Our investment calculator uses proven financial formulas to project wealth accumulation through:
- • Initial Investment: Your starting capital that begins earning returns immediately
- • Annual Return Rate: Expected yearly growth (stocks average 10%, bonds 4-6%, savings 1-3%)
- • Investment Period: Time horizon for growth (longer periods = exponential gains)
- • Regular Contributions: Additional monthly/yearly investments that accelerate growth
- • Compounding Frequency: How often returns are reinvested (more frequent = higher returns)
- • Tax Considerations: Impact of capital gains taxes on your final returns

Professional Investment Strategies & Tips
A 22-year-old investing $200/month until 65 will accumulate more wealth than someone starting at 35 investing $600/month. Start early!
Rule of thumb: Stock percentage = 100 - your age. Young investors can be more aggressive, older investors more conservative for wealth preservation.
Build 3-6 months of expenses in savings before aggressive investing. This prevents early withdrawal penalties and investment losses.
