- Monthly Contribution: $300
- Interest Rate: 6% annually
- Time Period: 25 years
What Happens?
- Your initial savings grow through compound interest
- Monthly contributions add consistent growth
- Over 25 years, your savings significantly increase
At the end of the period, your retirement fund could grow to over $200,000, depending on compounding.
