Formula Explanation

Future Value = Current Balance × (1+r)^n + (Annual Contribution + Match) × [((1+r)^n - 1) / r]

This calculates compound growth of your 401(k) including employer matching contributions and investment returns over time.

Employer Match = Annual Contribution × Match Percentage

Many employers match a percentage of your contributions, effectively doubling part of your savings.

Tips

Contribute enough to get the full employer match - it's free money.
Maximize your 401(k) contributions if possible (up to annual limits).
Start contributing early to maximize compound growth.
Consider increasing contributions with salary raises.
Review and rebalance your 401(k) investments regularly.
Don't withdraw early - you'll pay taxes and penalties.
