Your 401(k) Match is Free Money. Most People Leave Some on the Table.

Vanguard's annual "How America Saves" report has a stat that should be more famous: about 22% of workers with 401(k) plans do not contribute enough to get the full employer match. They are voluntarily leaving thousands of dollars a year unclaimed.

If that's you, this is the highest-return action you can take in personal finance. Bigger than picking the right index fund. Bigger than tax optimization. Bigger than the rent-vs-buy decision. It takes about 5 minutes to fix and pays out for the rest of your career.

How a typical match works

Common formulas:

Run yours through our 401(k) Match Calculator — it shows exactly what you're currently getting and what you'd get at full match.

What "not capturing it" costs

Example: $80k salary, 50%-match-up-to-6% plan, you contribute 3%.

If you bumped to 6%:

You went from $1,200 in free money to $2,400. The unclaimed $1,200/year, invested at 7% real return for 30 years, becomes about $113,000 at retirement. From five minutes of administrative work.

Why people leave it on the table

Three reasons:

  1. Auto-enrollment defaults are too low. Many plans default new employees to 3-4% contribution. The default sticks because most people never change it.
  2. Cash flow squeeze. They feel like they can't afford to contribute more. The retirement contribution comes out pre-tax, so the actual take-home reduction is smaller than the contribution amount.
  3. Confusion about the formula. "100% match up to 3% plus 50% match up to next 2%" is genuinely confusing. People don't know what number to target.

How to fix it

  1. Log into your benefits portal (Fidelity, Vanguard, Empower, whatever). Find "contribution rate."
  2. Find your match formula in the plan documents. If you can't find it, HR can tell you in 2 minutes.
  3. Use our calculator to figure out the target contribution rate.
  4. Set your rate to that number. Confirm. Done.

If you can't afford to jump straight to the full match, try the "auto-escalate" feature most plans have — it bumps your rate by 1% each year automatically. In 3-4 years you'll be at the full match without ever feeling the change.

The vesting catch

Some employers require you to stay 3-5 years before the match is fully yours. Check your plan's vesting schedule. If you might leave before vesting, the match is partially conditional — but you should still capture it; you might stay.

What if your employer doesn't offer a match?

Roughly 30% of US private-sector workers have no retirement plan through their employer. In that case, the priority is:

  1. Roth IRA up to $7,000 (2024 limit) — tax-free growth
  2. Brokerage account for additional retirement savings
  3. HSA if you have a high-deductible health plan — triple tax-advantaged
