Which Is Right for You? Decision Scenarios
The best choice depends on your individual circumstances. Here are common scenarios to help you decide:
The 50% match is an instant 50% return on your money. Always capture the full match before contributing elsewhere.
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.
Roth 401(k) has no income limits, and a backdoor Roth IRA conversion bypasses the income limit. Maximize both for tax-free retirement income.
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.
