Maximizing Your 401k Employer Match: Don't Leave Free Money Behind

The Free Money You Might Be Missing

According to Financial Engines, Americans leave an estimated $24 billion in unclaimed 401k matches on the table each year. That's free money from employers that employees simply don't collect.

The average missed match? $1,336 per person per year. Over a 30-year career with compound growth, that's potentially $200,000+ in retirement savings.

Let's make sure you're not part of that statistic.

How 401k Matching Works

An employer match is when your company contributes money to your 401k based on how much you contribute. It's part of your compensation—think of it as a bonus you have to "unlock" by saving.

Common Matching Formulas

Dollar-for-dollar match (100% match):

"We'll match 100% of your contributions up to 6% of your salary"

If you earn $80,000:

• You contribute 6% = $4,800
• Employer adds 6% = $4,800
• Total: $9,600/year

Partial match (50% match):

"We'll match 50% of your contributions up to 6% of your salary"

If you earn $80,000:

• You contribute 6% = $4,800
• Employer adds 3% = $2,400
• Total: $7,200/year

Tiered match:

"We'll match 100% on the first 3% and 50% on the next 2%"

If you earn $80,000:

• First 3% you contribute = $2,400 → 100% match = $2,400
• Next 2% you contribute = $1,600 → 50% match = $800
• Total match: $3,200

The Minimum to Contribute

At minimum, always contribute enough to get the full match. Anything less is leaving compensation on the table.

Understanding Vesting Schedules

Here's the catch: the match may not be "yours" immediately. Vesting schedules determine when you own the employer contributions.

Types of Vesting

Immediate vesting: You own 100% of employer contributions right away. Cliff vesting: You own 0% until a specific date (usually 2-3 years), then 100%. Graded vesting: Ownership increases over time: Why it matters: If you leave before fully vesting, you forfeit unvested employer contributions.

Strategies to Maximize Your Match

1. Know Your Match Formula

Check your benefits enrollment materials or ask HR. You need to know:

• Match percentage
• Maximum match
• Vesting schedule

2. Hit the Match Threshold Every Year

Set your contribution rate to at least capture the full match. If your company matches up to 6%, contribute at least 6%.

3. Watch for Contribution Limits

The 2025 401k contribution limit is $23,500 (plus $7,500 catch-up if you're 50+). Make sure you're not maxing out too early in the year—see "true-up" below.

4. Understand True-Up Policies

The problem: Some employers match per paycheck. If you max out your 401k early, you might miss matches on remaining paychecks. Example without true-up:

• $150,000 salary, 6% match ($9,000 max)
• You contribute 25% to max out by August
• August-December: No contributions = no match
• Lost match: ~$3,750

True-up: Some employers "true up" at year end to ensure you get the full match regardless of contribution timing. Check if your employer does true-up. If not, spread contributions evenly across the year.

5. Don't Leave for Unvested Money

If you're considering leaving and are close to a vesting cliff, calculate the cost of leaving early. Sometimes waiting a few months can mean thousands in vested matching funds.

6. Consider Mega Backdoor Roth

Some plans allow after-tax contributions beyond the normal limit (up to $69,000 total in 2025). If your plan offers this and allows in-plan Roth conversions, it's a powerful wealth-building tool.

Roth 401k vs Traditional: Does It Affect Matching?

Your employer match is always made pre-tax, regardless of whether you choose Roth or Traditional contributions.

• Your Roth contributions → Roth account
• Employer match → Traditional 401k (pre-tax)

This means if you choose Roth, you'll have two "buckets" in your 401k with different tax treatments.

Common Mistakes to Avoid

Mistake 1: Not Enrolling at All

Some employers auto-enroll, others don't. Make sure you're actually enrolled and contributing.

Mistake 2: Contributing Below the Match Threshold

If your company matches 6% and you're only contributing 4%, you're leaving 2% on the table.

Mistake 3: Not Increasing After Raises

When your salary goes up, increase your contribution percentage to capture more match.

Mistake 4: Ignoring Vesting

Factor vesting into job change decisions. Unvested money isn't really yours yet.

Mistake 5: Taking Loans from Your 401k

Loans reduce the balance that can earn returns and may affect future contributions/matching.

The Math: Why This Matters

Scenario: 30-year-old earning $60,000, employer matches 50% up to 6% That extra 3% contribution captures an additional $85,000+ in free money over your career.
