How Much Is a 401(k) Match Actually Worth?
TL;DR / Quick Take
A 6% match on $150k base is $9,000 of free money every year — but only if you're vested and actually contribute enough to capture the full match. Always run the numbers before you treat two offers as equal.
The Match Formula Most People Skip
Employers describe 401(k) matches in shorthand: "50% up to 6%" or "100% on first 4%." The translation matters. A 50% match up to 6% on a $150,000 salary means you contribute 6% ($9,000) and the company adds half ($4,500). A 100% match up to 4% means you put in 4% ($6,000) and they match dollar-for-dollar ($6,000).
Before comparing offers, write out each formula with your actual base salary. The difference between a 3% and 6% match on $180k is $5,400 per year — every year you're fully vested.
Checklist: What to Verify Before You Count It
- Match percentage and cap: What fraction of your contribution do they match, and up to what percent of salary?
- Vesting schedule: Is the match fully vested on day one, or does it cliff-vest over 3–4 years?
- Eligibility delay: Some plans don't start matching until you've been there 6–12 months.
- Your contribution requirement: You must contribute to get the match. Budget for that.
- Plan quality: High expense-ratio funds can erode match value over time — worth a glance, not a deep dive at offer stage.
Worked Example: Two Offers, Same Base
Jamie has two $160,000 base offers. Company A matches 100% up to 4%. Company B matches 50% up to 8%.
- Company A: Contribute $6,400 (4%), receive $6,400 match → $12,800 total/year
- Company B: Contribute $12,800 (8%), receive $6,400 match → $19,200 total/year
Company B's match is worth $6,400 more annually — but only if Jamie can afford to defer an extra $6,400 into the plan. If cash flow is tight in year one, Company A's simpler structure might actually net more in hand.
Frequently Asked Questions
Should I count an unvested 401(k) match in Adjusted Value?
If you plan to stay less than the vesting cliff, discount heavily or exclude it. A 4-year graded vest on a 2-year stay means you might only keep 50% of accumulated match.
Is a 401(k) match taxed?
Contributions are pre-tax; the match goes into your account pre-tax too. You pay ordinary income tax when you withdraw in retirement.
Can I negotiate a better 401(k) match?
Sometimes. Companies often have more flexibility on match formula or immediate vesting than on base salary, especially if they can't move the number you asked for.
