401(k) Match Explained — Free Money You’re Leaving on the Table

By James Walker — CFP® candidate, Boston MA · Updated January 2026

If your company offers a 401(k) match and you’re not taking it, you’re refusing a raise. That’s the simplest way I can put it. While studying for the CFP, the section on employer-sponsored plans was the part that made me email three friends to ask if they were maxing the match. Two weren’t. Let me walk you through the math.

What is a 401(k) and how does the employer match work?

A 401(k) is an employer-sponsored retirement account governed by Section 401(k) of the Internal Revenue Code. You contribute pre-tax (Traditional) or after-tax (Roth) money from each paycheck. Many employers also contribute money on your behalf when you contribute — this is the “match.”

The most common matching formulas I see:

• 50% of contributions up to 6% of salary — If you contribute 6%, employer adds 3%
• 100% of contributions up to 3% of salary, then 50% of the next 2% — Safe harbor “enhanced” match (very common)
• 100% of contributions up to 4% of salary — A “rich” match, more common at large or unionized employers
• Dollar-for-dollar up to a flat amount — e.g., $1 for $1 up to $2,000/year

How much is the 401(k) employer match worth?

Let’s do real math on a $60,000 salary with a 50%-up-to-6% match.

• You contribute 6% × $60,000 = $3,600/year
• Employer matches 50% of that = $1,800/year
• Total going into your 401(k) = $5,400/year

If you skip the match and only contribute, say, 2%, you put in $1,200 and the employer adds $600. You’ve walked away from $1,200 of free money this year. Over a 35-year career with that pattern, you forfeit roughly $400,000 in retirement value (assuming the match plus 7% returns).

What are the 2026 401(k) contribution limits?

Per the IRS 401(k) limits page, the 2026 limits are approximately:

• Employee elective deferral: $23,500 ($31,000 if 50+ with the standard catch-up)
• Total combined contributions (employee + employer): $70,000 ($77,500 if 50+)
• SECURE 2.0 super catch-up (ages 60–63): higher catch-up available — check IRS.gov for exact 2026 number

The employer match doesn’t count against your $23,500 employee limit — it’s separate, capped only by the higher combined limit.

What is vesting and why does it matter?

Vesting is when the employer’s contributions actually belong to you. If you leave the company before you’re fully vested, you forfeit the unvested portion of the match.

Common vesting schedules:

• Immediate vesting — The match is yours the moment it’s deposited. Best.
• Cliff vesting (3-year) — You get 0% if you leave before year 3, 100% after.
• Graded vesting (6-year) — Typically 20% per year starting in year 2, reaching 100% by year 6.

Read your Summary Plan Description (SPD) — your employer is required to give you one. Your contributions are always 100% vested instantly. Only the employer match is subject to the schedule.

Should I contribute to Roth 401(k) or Traditional 401(k)?

Same logic as the IRA decision (see our Roth IRA vs Traditional IRA guide):

• Roth 401(k) — After-tax contributions, tax-free growth and withdrawals. Better if you expect a higher future tax bracket.
• Traditional 401(k) — Pre-tax contributions (deductible now), taxed in retirement. Better if you expect a lower future bracket.

One important detail: the employer match is always pre-tax (Traditional), regardless of which bucket you contribute to. Under SECURE 2.0, employers can now offer to deposit the match as Roth, but most plans haven’t set this up yet. Check with your benefits team.

How should I think about the contribution priority order?

The CFP-curriculum framework most coursework teaches:

1. Step 1: Contribute to your 401(k) up to the full employer match (free money — do this even if you have credit card debt at 20% APR, because the match is a 50%+ instant return that beats even bad debt)
2. Step 2: Build your $1,000 starter emergency fund (see starter fund guide)
3. Step 3: Crush high-interest debt (anything over ~7–8% APR)
4. Step 4: Max your HSA if you have an HDHP
5. Step 5: Max your Roth IRA ($7,000 in 2026)
6. Step 6: Return to the 401(k) and increase toward the $23,500 cap
7. Step 7: Taxable brokerage for anything beyond that

What is the “true-up” provision and why should you care?

If you max your 401(k) ($23,500) early in the year — say by August — some plans stop matching for the rest of the year, even though you contributed enough on a percentage basis. You can lose thousands.

A true-up is a provision that catches the missed match at year-end. Not all plans have it. Read your SPD or ask HR. If your plan doesn’t have a true-up, spread your contributions evenly across all 12 months instead of front-loading.

What happens to my 401(k) when I leave my job?

Four options per the Department of Labor:

1. Leave it in the old employer’s plan (if balance > $7,000)
2. Roll it into your new employer’s 401(k)
3. Roll it into a Traditional IRA (most flexibility — usually my recommendation)
4. Cash it out (don’t — you’ll owe taxes plus a 10% penalty if under 59½)

A direct trustee-to-trustee rollover to an IRA at Vanguard, Fidelity, or Schwab takes 1–2 weeks and unlocks far more investment options than most employer plans offer.

Frequently Asked Questions

What if my employer doesn’t offer a 401(k) match?

Then your priority shifts. With no match, the order becomes: emergency fund, high-interest debt, HSA, Roth IRA, and only then back to the 401(k). The 401(k) is still valuable for tax-deferred growth and high contribution limits, but the urgency of capturing the match disappears. Some employers offer a 401(k) without a match — still useful, just lower priority.

Can I contribute to both a 401(k) and a Roth IRA in the same year?

Yes. The $23,500 401(k) limit and the $7,000 Roth IRA limit are completely separate. If you can max both, you’re contributing $30,500/year to retirement (plus your employer match on top). Income phase-outs apply to Roth IRA contributions if you earn above ~$150K single / $236K married for 2026 — verify on IRS.gov.

What is the highly compensated employee (HCE) limit?

If you earn above the IRS’s annual HCE threshold (approximately $160,000 for 2026 plan years), your contributions can be capped by your plan’s non-discrimination testing if too few rank-and-file employees participate. Your HR team will tell you if you’re affected. Solution at the company level: a safe harbor 401(k) plan, which automatically passes testing.

Should I take a 401(k) loan?

Generally no. You’re borrowing from your future self, missing market returns on the borrowed amount, and risking immediate taxation plus a 10% penalty if you leave the job before repayment. Use it only when the alternative is much worse — e.g., predatory short-term loans — and only as an absolute last resort.

What is an employer “true-up” and do I need it?

A true-up is a year-end recalculation that ensures you get your full match even if you contributed unevenly. If you max your contributions in 8 months and the match is calculated per paycheck (no true-up), you forfeit 4 months of match. Plans with true-up don’t have this issue. Ask HR. If your plan lacks it, just spread contributions evenly across 12 months.
