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

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

At minimum, contribute enough to capture your full employer match — anything less is leaving free money on the table. The 2026 contribution limit is $23,500 ($31,000 if 50+ via catch-up). Most retirement-on-track guidance is to save 15% of gross income across all retirement accounts. If your employer matches 5%, that means you contribute at least 10%.

Key facts

2026 employee contribution limit: $23,500 (under 50), $31,000 (50+ with catch-up).
New "super catch-up" contribution: ages 60–63 can add $11,250 more in 2026 (SECURE 2.0).
Combined limit (employer + employee) for 2026 is $70,000 (under 50) or $77,500 (50+).
Employer match averages 4.5% of salary across U.S. plans (Vanguard 2025 How America Saves).
70% of plans offer immediate vesting on the employee portion; employer match vesting follows the plan's schedule (typically 3–6 years).
Roth 401(k) contributions count toward the same $23,500 limit, but the money grows tax-free with no RMDs starting in 2024.
Mandatory auto-enrollment at 3%+ now applies to all new 401(k) plans starting in 2025 (SECURE 2.0).
High-earner Roth catch-up rule: starting in 2026, employees with prior-year wages over $145,000 must make catch-up contributions on a Roth basis — they can no longer be pre-tax.

Common follow-up questions

How much do I need in my 401(k) to retire?

Most rule-of-thumb guidance is 10–12 times your final annual salary by age 65. For a $100,000-earner, that's $1.0M–$1.2M. The 4% rule says a $1M portfolio supports about $40,000/year in inflation-adjusted withdrawals. Add Social Security for a typical mid-career earner ($30,000–$45,000/year at FRA) and the $1M–$1.5M target replaces 70–80% of pre-retirement income.

Should I do Roth or traditional 401(k)?

Traditional if you're in a high bracket now and expect a lower bracket in retirement. Roth if you expect higher rates later, want tax diversification, or want to leave tax-free money to heirs. Most planners recommend a mix — at least some Roth so you have tax-free withdrawal flexibility in retirement.

What is the catch-up contribution for 2026?

Workers age 50+ can contribute an extra $7,500 above the base limit, totaling $31,000. SECURE 2.0 added a "super catch-up" for ages 60–63 of $11,250 above the base, totaling $34,750. After age 63, you revert to the standard 50+ catch-up.

Can I contribute to both a 401(k) and an IRA?

Yes, the limits are separate. The 2026 IRA contribution limit is $7,000 ($8,000 if 50+). However, IRA deduction limits phase out at higher incomes when you have a 401(k) — fully phased out at $103,000 (single) or $172,000 (MFJ) MAGI. Consider a backdoor Roth if your income exceeds the deduction limit.

When can I withdraw from my 401(k) without penalty?

Age 59½ for full penalty-free access. The "Rule of 55" allows penalty-free 401(k) withdrawals if you separate from your employer in or after the year you turn 55 — but only from that employer's 401(k), and you can't roll into an IRA first. Public-safety workers (police, firefighters) get age 50.

When this doesn't apply

These limits and rules apply to private-sector 401(k) plans. 403(b), 457(b), TSP, and SEP-IRA plans have similar but not identical rules. Self-employed Solo 401(k) limits go higher because you contribute as both employee and employer.
