Quick Answer
How much should I contribute to my 401(k)?
At minimum, contribute enough to get your full employer match - it's free money. For 2025, the contribution limit is $23,500 ($31,000 if age 50-59 or 64+, $34,750 for ages 60-63). Contributing 10% of a $75,000 salary with a 50% employer match on 6% grows to approximately $921,000 over 30 years at 7% return.
Calculate your projected 401(k) balance and see how employer match and compound growth work together.
Key Takeaways
- Always get the full employer match - it's free money with instant 50-100% return
- 2025 contribution limits: $23,500 base, $31,000 with catch-up (50+), $34,750 super catch-up (60-63)
- Pre-tax contributions reduce your taxable income and grow tax-deferred until retirement
- Starting early matters: $500/month for 30 years at 7% = $566,000+ (you contribute $180K, earn $386K)

Understanding Your 401(k)
What is a 401(k)?
A 401(k) is an employer-sponsored retirement account where you contribute pre-tax dollars. Your contributions reduce taxable income today, and investments grow tax-deferred until withdrawal (typically age 59 1/2+).
2025 Limits: $23,500 base, $31,000 with catch-up (50+), $34,750 super catch-up (60-63).
The Power of Employer Match
Employer matching is free money. A 50% match on 6% of salary means instant 50% return on your contribution.
- Earn $75,000, contribute 6% ($4,500)
- Employer adds $2,250 (50% match)
- That's $6,750 total - free $2,250 bonus!
Compound Growth
Compound interest means you earn returns on your returns. Over decades, this creates exponential growth.
- $500/month for 30 years at 7%
- You contribute: $180,000
- You earn: $386,000+ in growth!
Catch-Up Contributions (50+)
At age 50+, you can contribute extra to accelerate retirement savings:
- Ages 50-59 or 64+: +$7,500/year
- Ages 60-63: +$11,250/year (super catch-up)
- Great if you started saving late
401(k) Balance By Age: How Do You Compare?
Wondering if you're on track? Here are 401(k) benchmarks based on Fidelity data (Q3 2024).
| Age Range | Average Balance | Median Balance | Target (Salary Multiple) |
|---|---|---|---|
| 20-29 | $16,500 | $7,350 | 0.5x salary by 30 |
| 30-39 | $56,100 | $23,600 | 1x salary by 35 |
| 40-49 | $129,300 | $48,300 | 2-3x salary by 45 |
| 50-59 | $223,800 | $72,400 | 4-6x salary by 55 |
| 60-69 | $263,700 | $87,900 | 6-8x salary by 60 |
| 70+ | $280,400 | $108,700 | 10x salary (retirement) |
The median is a better benchmark than the average because high earners skew the average upward. If your balance is above the median for your age, you're doing better than half of Americans.
Frequently Asked Questions
At minimum, contribute enough to get your full employer match - it's free money. Financial experts recommend saving 10-15% of income for retirement. For 2025, you can contribute up to $23,500 ($31,000 if age 50-59 or 64+, $34,750 if age 60-63).
The most common match is 50% of your contributions up to 6% of salary (effectively 3% of salary). A 100% match up to 3-6% is considered excellent. Any employer match is valuable - always contribute enough to get the full match.
Historically, the S&P 500 has averaged about 10% annually, but a conservative planning estimate is 6-8% to account for inflation, fees, and volatility. A diversified portfolio typically averages 7-9% over 30+ years.
If you're 50 or older, you can contribute extra beyond the standard limit. For 2025: ages 50-59 or 64+ can add $7,500 (total $31,000), ages 60-63 can add $11,250 "super catch-up" (total $34,750). This helps accelerate savings if you started late.
Priority order: 1) Contribute to 401(k) up to employer match (free money), 2) Max out Roth IRA if eligible ($7,000 in 2025), 3) Return to 401(k) and contribute more. This maximizes free money and provides tax diversification.
Options: 1) Roll over to new employer's 401(k), 2) Roll over to an IRA (more investment choices), 3) Leave it with old employer if allowed, 4) Cash out (not recommended - you'll pay taxes and 10% penalty if under 59 1/2). Rolling over preserves tax advantages.
