How the 401(k) Works

A 401(k) is an employer-sponsored retirement account with tax advantages. In 2026, you can contribute up to $23,500 per year (plus $7,500 catch-up if 50+).

Why Employer Match Is Free Money

If your employer matches 5% and you earn $80K, that's $4,000/year free. Over 35 years at 7% return, that match alone grows to over $550K. Always contribute at least enough to get the full match.

Traditional vs Roth 401(k)

  • Traditional 401(k) — Contributions are pre-tax. Pay taxes when you withdraw in retirement. Best if you expect to be in a lower tax bracket later.
  • Roth 401(k) — Contributions are after-tax. Withdrawals are tax-free. Best if you expect higher taxes in retirement or are in a low bracket now.

401(k) Contribution Limits (2026)

  • Employee: $23,500
  • Catch-up (age 50+): additional $7,500
  • Total (employee + employer): $70,000

Frequently Asked Questions

How much should I contribute to my 401(k)?

At minimum, contribute enough to get your full employer match (typically 3-6%). Ideally, aim for 10-15% of your salary. If you can max out the $23,500 limit, even better.

What happens if I change jobs?

You can roll your 401(k) into your new employer's plan, roll it into an IRA, or leave it where it is. Rolling into an IRA gives you more investment options and often lower fees.

Can I withdraw from my 401(k) early?

Withdrawals before age 59½ typically incur a 10% penalty plus taxes. Exceptions include hardship withdrawals, certain medical expenses, and Rule of 55 (leaving your job at 55+).
