All About 401(k) & Retirement Growth Calculator
The most powerful wealth-building tool for employees is the tax-advantaged retirement account. This calculator shows how your recurring contributions and the 'free money' from your employer turn into a multi-million dollar nest egg.
How to Use This Tool
Enter your current annual gross salary.
Input the percentage of your salary you contribute to your 401(k) or pension.
Enter the percentage your employer matches (if any).
Specify your current retirement account balance and how many years until you plan to retire.
Select an expected annual rate of return (historically ~7-10% for stock-heavy portfolios).
Practical Example
Earning $75k with a 6%+3% match at 7% return for 25 years results in ~$820,000.
Common Questions
What is a 'good' contribution rate?
Most experts recommend saving at least 15% of your gross income for retirement, including employer matches.
Can I withdraw the money early?
Usually not without a 10% penalty and paying taxes, unless it is for specific qualified reasons like a first-home purchase or medical emergency.
What return rate should I use?
A conservative estimate is 5-6%, while a more optimistic (historical average) estimate for the stock market is 8-10%.
