Example Calculation

Let’s take a practical example:

Current Balance: $20,000
Monthly Contribution: $500
Years Until Retirement: 25
Expected Annual Return: 7%

Using the calculator:

Total Contributions: $500 × 12 months × 25 years = $150,000
Estimated Growth: Compounding at 7% annually results in approximately $265,000 in growth.
Future 401k Value: $20,000 (current balance) + $150,000 (contributions) + $265,000 (growth) = $435,000

This projection allows you to visualize your retirement wealth and adjust contributions or investment strategies accordingly.
