If your employer offers a 401k match and you're not contributing enough to get the full match, you're literally turning down free money. About 25% of employees don't contribute enough to get their full employer match, leaving an average of $1,336 per year on the table.

How 401k Matching Works

A typical match: your employer contributes 50 cents for every dollar you contribute, up to 6% of your salary. If you earn $60,000 and contribute 6% ($3,600), your employer adds $1,800. That's a 50% instant return on your investment β€” no stock market can guarantee that.

Common match formulas:

  • Dollar-for-dollar up to 3%: You put in 3%, they put in 3%. Total: 6%.
  • 50% match up to 6%: You put in 6%, they put in 3%. Total: 9%.
  • Dollar-for-dollar up to 6%: The gold standard. You put in 6%, they put in 6%. Total: 12%.

How Much Should You Contribute?

At minimum: Enough to get the full employer match. This is the #1 financial priority after basic expenses. Contributing less means rejecting free money.

Ideally: 15% of your gross income for retirement (including employer match). If your employer matches 3%, contribute at least 12% yourself.

Maximum: $23,500 per year in 2026 ($31,000 if you're 50+).

Vesting Schedules

Your contributions are always 100% yours. But employer match money may have a vesting schedule β€” you only keep it after working there a certain number of years.

  • Immediate vesting: Match money is yours right away.
  • Cliff vesting: 0% vested until year 3, then 100% vested.
  • Graded vesting: 20% per year β€” fully vested after 5 years.

Check your vesting schedule before leaving a job. If you're close to a vesting milestone, staying a few more months could mean thousands of dollars.

What to Invest In

If you don't know what to choose, pick a target-date fund matching your expected retirement year (e.g., Target 2055 Fund if you'll retire around 2055). It automatically adjusts from aggressive to conservative as you age. Set it and forget it.

Common Mistakes

  • Not enrolling at all: Some companies auto-enroll at 3%, which may not be enough for the full match
  • Cashing out when changing jobs: Roll your 401k to an IRA or new employer's plan. Cashing out costs you 10% penalty + income taxes
  • Not increasing contributions with raises: When you get a raise, increase your 401k percentage by 1-2%. You won't miss money you never saw in your paycheck
🎯 Key Takeaway: Your 401k employer match is the highest-return investment available β€” a guaranteed 50-100% return. At minimum, contribute enough to get the full match. Choose a target-date fund if you're unsure what to invest in. Check your vesting schedule, and never cash out when changing jobs. A 25-year-old who maxes their match and invests $1,800/year of employer match at 8% returns will have $255,000+ from the match alone by age 65.
