Frequently Asked Questions
What is the 2026 401(k) contribution limit?
For 2026, the IRS limit is $24,000 for employees under 50, plus a $7,500 catch-up contribution for those 50 and older (totaling $31,500). The combined employer + employee limit is $71,000 ($78,500 with catch-up). These limits adjust annually for inflation.
Should I always contribute up to the employer match?
Yes โ almost always. Employer match is free money: a typical "50% match up to 6%" gives you an instant 50% return on your contribution. Skipping it is leaving compensation on the table. Contribute at least the full match before paying down low-rate debt or saving in a regular brokerage account.
Roth 401(k) vs Traditional 401(k) โ which is better?
Traditional reduces taxable income today; you pay tax on withdrawals. Roth uses after-tax dollars; withdrawals are tax-free. If you expect a higher tax bracket in retirement โ Roth. If you expect lower โ Traditional. When uncertain, splitting 50/50 hedges your tax-rate risk.
What happens if I leave my job?
You have four options: (1) leave the money in the old employer's plan, (2) roll it over to your new employer's 401(k), (3) roll it over to an IRA (most flexible), or (4) cash out (worst option โ you'll pay income tax + 10% penalty if under 59ยฝ). Always do a direct rollover to avoid mandatory 20% withholding.
How much should I have in my 401(k) by age?
Common benchmarks (Fidelity): 1ร salary by 30, 3ร by 40, 6ร by 50, 8ร by 60, 10ร by retirement. So at $75K salary: $75K by 30, $225K by 40, $450K by 50. These are guides, not rules โ your actual need depends on lifestyle and expected retirement spending.
