401k Employer Match Basics

An employer match is money your company adds to your 401k when you contribute — often described as the closest thing to free money in personal finance.

How matches are structured

Common formulas include:

• Full match: 100% of your contributions up to a cap (e.g., 100% of the first 4% of salary).
• Partial match: 50 cents per dollar up to a cap (e.g., 50% of the first 6%).
• Tiered match: different rates at different contribution levels.

A "50% of the first 6%" match means contributing 6% of salary earns you an extra 3% from your employer — an immediate 50% return on those dollars.

Contribute at least to the match

Whatever your other financial priorities, contributing enough to capture the full match almost always comes first. Leaving match dollars on the table is forfeiting part of your compensation.

Vesting schedules

Your own contributions are always 100% yours. Employer contributions may vest over time:

• Cliff vesting: you own 0% until a set anniversary (up to 3 years), then 100%.
• Graded vesting: ownership phases in, commonly 20% per year over 2–6 years.

Leaving a job before vesting means forfeiting the unvested employer money — worth checking before a job change.

Watch the timing

Some plans match per paycheck rather than annually. Maxing out your 401k early in the year can cause missed match in later pay periods unless the plan has a true-up provision. If you front-load contributions, confirm whether your plan trues up.

Key takeaways

• Know your plan's exact match formula and contribute at least enough to capture all of it.
• Vesting schedules determine when employer money becomes truly yours.
• Check for a true-up provision before front-loading contributions.
