Frequently Asked Questions

What is the 401k contribution limit for 2025?

In 2025, employees can contribute up to $23,500 to a 401k (up from $23,000 in 2024). Workers aged 50 and older can add a catch-up contribution of $7,500, for a total of $31,000. The combined employee + employer limit is $70,000. Always try to at least contribute enough to capture your full employer match.

What is the difference between a Traditional 401k and a Roth 401k?

Traditional 401k contributions are pre-tax (reduce your taxable income now, taxed at withdrawal). Roth 401k contributions are post-tax (no deduction now, but withdrawals in retirement are tax-free). Roth is generally better if you expect to be in a higher tax bracket in retirement. Many employers offer both options.

How does employer 401k matching work?

Most employers match a percentage of your contributions up to a salary cap. For example, '100% match up to 6% of salary' means if you earn $80,000 and contribute 6% ($4,800), your employer adds another $4,800 — free money. Never leave employer match on the table. It's an instant 100% return on matched dollars.

What is the 4% rule for retirement withdrawals?

The 4% rule states you can safely withdraw 4% of your retirement portfolio in Year 1, then adjust for inflation annually, with a high probability your savings will last 30+ years. On a $1 million portfolio, that's $40,000/year or $3,333/month. This calculator uses the 4% rule to estimate your monthly retirement income.

At what age can I withdraw from my 401k without penalty?

You can withdraw from your 401k penalty-free starting at age 59½. Withdrawals before 59½ incur a 10% early withdrawal penalty plus income tax. Required Minimum Distributions (RMDs) must begin at age 73 (as of 2023 SECURE 2.0 Act). Roth 401k accounts are also subject to RMDs unless rolled over to a Roth IRA.
