Frequently asked questions

  • How much will my 401(k) be worth?

    It depends on your contribution rate, employer match, return, and years invested. A $75,000 earner contributing 10% with a 50%-up-to-6% match and 7% returns could reach well over $700,000 in 25 years — most of it from compound growth.

  • How does employer match work?

    A common match is 50% of what you contribute up to 6% of salary — so contributing 6% adds another 3% of salary for free. Always contribute at least enough to capture the full match.

  • What's the 401(k) contribution limit for 2026?

    The 2026 employee elective deferral limit is $24,500 (plus catch-up contributions if you're 50 or older). Employer match is on top of that limit.
