Should I choose traditional or Roth 401(k)?

Choose Roth 401(k) if you're in a lower tax bracket now than you expect in retirement. Choose Traditional 401(k) if you're in a high bracket now and want the current-year tax deduction. Many advisors recommend splitting contributions between both for tax diversification.

What Is a 401(k)?

A 401(k) is an employer-sponsored retirement savings account. You contribute a percentage of your paycheck before (or after, with Roth) income taxes are calculated. Employers often match a portion of what you contribute — which is essentially free money added to your account.

Investments inside the account grow tax-deferred (Traditional) or tax-free (Roth). You pay a 10% penalty plus taxes for early withdrawals before age 59½, with some exceptions.

The Employer Match: Never Leave It Behind

The employer match is the most valuable benefit in your compensation package. A common structure: your employer matches 50% of your contributions up to 6% of your salary. That means if you earn $60,000 and contribute 6% ($3,600), your employer adds $1,800 — a 50% instant return before the market moves an inch.

✅ Common Employer Match Structures

50% match up to 6% of salary — the most common structure. Contribute at least 6% to capture the full match.
100% match up to 3% of salary — contribute at least 3% to get the full match.
Dollar-for-dollar up to 4% — contribute 4% to max it out.
No match — still valuable for tax advantages, but prioritize an IRA first if you have limited funds.

How to Choose Your 401(k) Investments

Most 401(k) plans offer a menu of mutual funds. Your job: find the lowest-cost index funds available and use them. Ignore the actively managed funds — decades of data show that 85%+ of active managers underperform their index benchmark over 15 years, while charging 5–20x higher fees.

📊 What to Look For in 401(k) Funds

Expense ratio below 0.20% — the annual fee charged by the fund. Lower is always better. Look for index funds.
S&P 500 index fund — if available, this is usually the best core holding
Total market index fund — even broader diversification than S&P 500
Target-date fund — automatically adjusts risk as you near retirement. Good default for hands-off investors. Check the expense ratio.
Avoid funds with expense ratios above 0.5% — over 30 years, a 1% annual fee can cost you 25% of your ending balance

Roth 401(k) vs Traditional 401(k)

Many plans now offer both options. The choice is identical to Roth IRA vs Traditional IRA:

Traditional 401(k): Contributions reduce your taxable income today. Withdrawals in retirement are taxed as income. Best if your tax rate today is higher than it will be in retirement.
Roth 401(k): Contributions are after-tax (no current deduction). Withdrawals in retirement are completely tax-free. Best if your tax rate will be higher in retirement.

A practical strategy: split contributions 50/50 between Traditional and Roth for "tax diversification" — you'll have both tax-free and tax-deferred money in retirement, giving you flexibility to manage your tax bracket each year.

The Optimal Contribution Strategy

Here's the priority order for where to put your retirement savings dollars:

401(k) up to the employer match — 100% priority. Non-negotiable free money.
Roth IRA to the max — $7,000 in 2026. Better investment options than most 401(k)s, and tax-free growth.
HSA (if eligible) — triple tax advantage: deductible, grows tax-free, withdraws tax-free for medical expenses.
Back to 401(k) up to the limit — maximize the remaining $16,500 after your IRA contribution.
Taxable brokerage account — for savings beyond tax-advantaged limits.

Understanding Vesting Schedules

Your own contributions are always 100% yours immediately. But employer contributions often follow a vesting schedule — you only "own" them after working for the company for a certain time.

Immediate vesting: Employer match is yours from day one
Cliff vesting: 0% ownership until you hit a date (e.g., 3 years), then 100% instantly
Graded vesting: Gradual ownership over years (e.g., 20%/year over 5 years)

Know your vesting schedule before leaving a job — you may want to wait a few months to capture more employer contributions.
