Which Is Right for You? Decision Scenarios

The best choice depends on your individual circumstances. Here are common scenarios to help you decide:

Your employer matches 50% up to 6% of salary
Recommendation: 401(k) first (up to match), then IRA

The 50% match is an instant 50% return on your money. Always capture the full match before contributing elsewhere.

Your employer offers no match and high-fee funds
Recommendation: IRA first, then 401(k)

Without a match, the IRA's lower costs and better fund selection provide more value. Use the 401(k) for additional savings beyond the IRA limit.

You're a high earner over the Roth IRA income limit
Recommendation: Roth 401(k) + Backdoor Roth IRA

Roth 401(k) has no income limits, and a backdoor Roth IRA conversion bypasses the income limit. Maximize both for tax-free retirement income.

You're self-employed
Recommendation: Solo 401(k)

A Solo 401(k) lets you contribute as both employee ($23,500) and employer (25% of net earnings), up to $70,000 total in 2026.

Real-World Example: The Employer Match: Turning $4,700 Into $7,050 Instantly

Taylor earns $78,333/year and contributes 6% ($4,700) to a 401(k). With a 50% employer match, the employer adds $2,350, making the total $7,050 — an instant 50% return. Over 30 years at 8% growth, Taylor's $4,700/year contributions plus match grow to $851,000. Without the match (investing $4,700/year in an IRA instead), the total would be only $567,000. The employer match adds $284,000 in extra retirement wealth.

Frequently Asked Questions

Should I max out my 401(k) or IRA first?
Step 1: Contribute to your 401(k) up to the employer match. Step 2: Max out your IRA ($7,000). Step 3: Go back and max out the 401(k) ($23,500). This order optimizes free money + low-cost investments + high contribution limits.
Can I contribute to both a 401(k) and IRA?
Yes! The limits are separate. You can contribute $23,500 to a 401(k) AND $7,000 to an IRA in 2026. However, Traditional IRA deductibility may be limited if you have a 401(k).
What happens to my 401(k) when I leave my job?
You can: (1) roll it into an IRA (best option for most), (2) leave it in the old employer's plan, (3) roll it into your new employer's plan, or (4) cash it out (avoid this — you'll pay taxes + 10% penalty).
What is a Solo 401(k)?
A retirement plan for self-employed individuals with no full-time employees. It allows contributions as both employer and employee, with a combined limit of $70,000 in 2026 ($77,500 if 50+).
