Definition

401(k) employer match is when your employer contributes additional money to your retirement account based on what you contribute. Typical formula: 50% of your contributions up to 6% of salary. Skipping the match is leaving money on the table — typically a 50-100% instant return.

What it means

The most common match structure is “50% match up to 6% of salary”: contribute 6% of salary, employer adds 3%. On a $100K salary, contribute $6K, employer adds $3K = $9K/year. Some employers offer dollar-for-dollar match (more generous); some offer tiered matching that gets more generous at higher contribution levels (Walmart, Ford). Vesting schedules determine when match becomes “yours” — cliff vesting (3 years, then 100%), graded vesting (20% per year over 5 years), or immediate. Leaving before fully vested forfeits unvested match.

Formula

If salary = $S and match = X% of contribution up to Y% of salary, employer adds min(your_contribution, Y% × $S) × X%

Why it matters

The match is the single highest-return contribution most workers ever make. A 50% match is an instant 50% return on contributed dollars before any market movement. Compounded over a 30-year career at 7% real return, the match alone (3% of salary on a $100K earner = $3K/year) becomes ~$300K. Plus your matched contribution becomes another $600K. Skipping the match is forfeiting a ~$300K endowment for nothing.

Example

$100K salary, 50% match up to 6%. Contributing 6% ($6K) gets you $3K match = $9K/year total contribution. Over 30 years at 7% real return, the $3K/year match alone grows to ~$284K. Skipping = leaving $284K on the table.

Frequently asked questions

What if I can’t afford to max out?

At minimum, contribute up to the match. Even if it strains other parts of your budget, the 50%+ instant return beats nearly any other use of the money. Consider it part of your salary.

What’s a vesting cliff?

Cliff vesting: 0% vested until X years (typically 3), then jump to 100%. Leaving before the cliff forfeits ALL match. Graded vesting: incremental, e.g., 20% per year over 5 years.

Do I lose match if I leave my job?

Vested portion is yours; unvested portion is forfeited. After leaving, you can roll the 401k to your new employer’s plan or to an IRA — vested balance moves with you.
