How this 401k Growth Calculator works
Our 401(k) calculator projects the future value of your retirement account by compounding your contributions, employer matching, and estimated annual investment returns. It assumes your contributions occur monthly and that your investment returns are reinvested, accelerating the growth of your nest egg through the power of compound interest.
Why this matters for your wealth
The 401(k) is one of the most powerful wealth-building tools available due to its tax advantages and potential employer match (which is essentially free money). Starting early makes a simplified difference; a dollar invested in your 20s can be worth significantly more than a dollar invested in your 40s. Use this tool to see if you are on track to retire with the lifestyle you desire.
Frequently Asked Questions
How much should I contribute to my 401(k)?
At a minimum, contribute enough to get your full employer match. Financial experts often recommend saving 15% of your gross income for retirement, which can be a combination of 401(k) and IRA contributions.
What is a realistic annual return for a 401(k)?
The S&P 500 has historically returned about 10% annually before inflation. For long-term projections, a conservative estimate of 7-8% is often used to account for market volatility and inflation.
