Example: Estimating 401k Savings

Suppose a 30-year-old employee has a current balance of $10,000, earns $60,000 annually, contributes 10% of salary, and has an employer match of 5%. Assuming a 7% annual return and planning to retire at 65:

Years to Retirement: 65 − 30 = 35 years
Monthly Contributions: ($60,000 × 10%) ÷ 12 = $500
Employer Match Contribution: ($60,000 × 5%) ÷ 12 = $250
Monthly Growth: Contributions compounded at 7% annually
Projected Balance: Using the calculator, the total balance grows to approximately $1,050,000, with $315,000 personal contributions, $157,500 employer contributions, and $577,500 interest earned.

This example illustrates the impact of compound interest and employer match on long-term savings.
