How does a 401k work?

You contribute a percentage of each paycheck to your 401k account, invested in funds you select. Your employer may add matching contributions. The balance grows tax-deferred (Traditional) or tax-free (Roth) until withdrawal at retirement. For Traditional, withdrawals are taxed as ordinary income. For Roth, qualified withdrawals are tax-free.

What is a 401k rollover?

Moving your 401k balance from an old employer’s plan to a new 401k or IRA. A direct rollover (custodian-to-custodian) is tax-free. An indirect rollover (you receive a check) requires depositing the full amount within 60 days, but triggers 20% mandatory withholding you must cover out of pocket until refunded.

What is vesting in a 401k?

Vesting determines how much of your employer’s contributions you own. Your own contributions are always 100% vested immediately. Employer match may vest immediately, after 3 years (cliff), or gradually over 2–6 years (graded). Check your plan’s vesting schedule before leaving any job.

Can I have a 401k and an IRA at the same time?

Yes. 401k and IRA contribution limits are completely separate. You can max both simultaneously. The optimal order: capture full employer match, max Roth IRA ($7,000), then continue 401k beyond match.

What happens to my 401k if I die?

Your designated beneficiaries inherit the account. Spouse beneficiaries have the most flexibility (can roll into their own IRA). Non-spouse beneficiaries typically must withdraw all funds within 10 years under the SECURE 2.0 Act rules. Without designated beneficiaries, the account goes through probate.

Is 401k better than a savings account?

For retirement savings, overwhelmingly yes. A Traditional 401k reduces your taxable income dollar-for-dollar and grows tax-deferred. A savings account earns post-tax interest taxed annually. Over 30 years at equivalent rates, the 401k typically produces 30–50% more wealth after tax. For emergency funds (money you might need quickly), a high-yield savings account is appropriate.

Investment and Account Questions

Q: What funds should I choose in my 401k? For most investors: a target-date fund matching your retirement year (lowest complexity), or a three-fund portfolio (S&P 500 index + international index + bond index). Prioritize expense ratios under 0.2%. Avoid actively managed funds with expense ratios above 0.5%.

Q: Can I lose all my money in a 401k? Only if you invest in assets that go to zero (individual stocks or sector funds of bankrupt companies). Diversified index funds have never gone to zero. The U.S. stock market has recovered from every historical decline, including 50%+ crashes, within 5 years.

Q: Does my 401k earn dividends? Yes — mutual funds and ETFs inside your 401k distribute dividends, which are automatically reinvested into additional fund shares. This is the compounding mechanism for equity accounts.

Withdrawal and Rollover Questions

💡The RMD Planning Note

Required Minimum Distributions (RMDs) start at age 73 for Traditional 401k accounts. The IRS calculates the minimum you must withdraw each year based on account balance and life expectancy tables. Failing to take your RMD triggers a 25% excise tax on the amount not withdrawn. Plan for RMDs as part of your retirement income strategy.
