A 401(k) employer match is money your company adds to your retirement account based on the salary you contribute yourself, and it is compensation you only receive by deferring enough of your own pay to trigger the plan formula.
A 401(k) employer match is a contribution your employer deposits into your 401(k) tied to what you defer from your own paycheck, commonly 50 cents or $1 per dollar up to 3% to 6% of pay. For 2026, the match does not count toward your $24,500 employee deferral limit, but it does count toward the combined $72,000 annual-additions cap (Source: IRS Notice 2025-67, 2025).
What is a 401(k) employer match?
A 401(k) employer match is a contribution your employer adds to your 401(k) in proportion to the money you defer from your own salary. The IRS states that in a traditional 401(k) plan the “employer can make matching contributions for an employee who contributes elective deferrals to the 401(k) plan” (Source: IRS, 401(k) Plan Overview, 2026). The match is separate from your salary deferral and only arrives when you contribute.

The match is often called “free money” because it adds employer dollars on top of what you already save, though it becomes fully yours only after you meet the plan’s vesting conditions. In a traditional 401(k), matching contributions grow tax-deferred and “don’t reduce the amount you can contribute to the plan from your salary” (Source: IRS, Matching Contributions Help You Save More for Retirement, 2026).
How does it work?
A 401(k) employer match works by applying a formula to your own contributions, up to a set percentage of your salary. Your employer chooses the formula, sets the cap, and deposits the match into your account, usually each pay period. Two variables drive the amount: the match rate (cents per dollar you defer) and the cap (the percentage of pay the match applies to).
Full, partial, and tiered match types
Employers use three broad match structures. A full match (also called dollar-for-dollar or 100%) adds $1 per $1 you contribute up to the cap. A partial match adds a fraction, commonly 50 cents per dollar, up to the cap. A tiered match blends rates across pay bands, such as 100% on the first slice and 50% on the next.
| Match type | Rate | What it means |
|---|---|---|
| Full (dollar-for-dollar) | 100% | $1 of employer money per $1 you contribute, up to the cap |
| Partial | Often 50% | $0.50 of employer money per $1 you contribute, up to the cap |
| Tiered | Blended | Different rates on different pay bands (for example 100% then 50%) |
Common match formulas
Two match formulas appear most often. The first is a tiered design: 100% on the first 3% of pay plus 50% on the next 2%, which produces a 4% employer contribution when you defer 5%. The second is a flat partial design: 50% up to 6% of pay, producing a 3% employer contribution when you defer 6%. Each plan document sets the exact rate and cap that apply to you.
| Formula | You contribute to max it | Effective employer match |
|---|---|---|
| 100% on first 3% + 50% on next 2% | 5% of salary | 4% of salary |
| 50% up to 6% of salary | 6% of salary | 3% of salary |
| IRS example: 50% up to 5% of salary | 5% of salary | 2.5% of salary |
The first row is a generic industry example rather than an IRS-published formula. Each plan document controls the exact rate and cap, stated in your summary plan description.
Worked dollar examples
Turning a 401(k) employer match formula into dollars requires only your salary and your contribution rate. The two examples below apply a 50%-up-to-6% formula to show how the match is calculated and how deferring below the cap leaves employer money unclaimed. These are arithmetic illustrations, not projections.
Example 1: $50,000 salary, 6% contribution
This example uses a 50% match on contributions up to 6% of salary. A saver earning $50,000 who contributes the full 6% defers $3,000 of their own pay across the year. Because the contribution reaches the cap, the employer match applies in full, and the steps below show how the $50,000 salary turns into a combined deposit.
- You contribute 6% of $50,000, which is $3,000 for the year.
- Your employer matches 50% of that, which is $1,500.
- Total added to your 401(k): $4,500 for the year.
Example 2: $80,000 salary, 3% contribution (under the cap)
This example shows what happens when a saver contributes below the match cap. A worker earning $80,000 who defers only 3% puts in $2,400, even though the same 50%-up-to-6% formula would match a larger contribution. The steps below show the match earned at 3% and how much employer money stays unclaimed until the contribution rises toward the 6% cap.
- You contribute 3% of $80,000, which is $2,400.
- The match is 50% of that 3%, which is $1,200, and part of the match goes unclaimed because the formula would match up to 6%.
- Raising your contribution to 6% ($4,800) would raise the match to $2,400.
The compensation an employer can use to figure a match is capped at $360,000 for 2026 (Source: IRS Notice 2025-67, 2025).
What is the average and a good match?
The average 401(k) employer match was 4.6% of pay in 2023, with a median of 4.0%, and about 78% of plans offered a match, according to Vanguard’s How America Saves 2024 report. As a general benchmark, many observers describe a match of 4% to 6% of pay as competitive and a match above 6% as generous. The figure that governs your account is your own plan’s formula, not an industry average.
| Benchmark | Figure | Source |
|---|---|---|
| Average employer match | 4.6% of pay | Vanguard, How America Saves 2024 |
| Median employer match | 4.0% of pay | Vanguard, How America Saves 2024 |
| Plans offering any match | About 78% | Vanguard, How America Saves 2024 |
| Plans with immediate vesting | About 44% | Vanguard, How America Saves 2024 |
Vesting: when the match becomes yours
Vesting determines how much of the 401(k) employer match you keep if you leave. Your own contributions are always 100% yours, but the IRS lets a plan require a set number of years of service before the match fully vests (Source: IRS, 401(k) Plan Overview, 2026). Only about 44% of plans vest the match immediately (Source: Vanguard, How America Saves 2024).
Cliff versus graded vesting
Employers generally use one of two vesting schedules for matching contributions, subject to statutory maximums under 26 U.S. Code Section 411(a)(2)(B). A cliff schedule gives you 0% until a set date, then 100% at once, with a general statutory maximum of a 3-year cliff. A graded schedule vests you in rising increments, with a general statutory maximum of 2-to-6-year graded (Source: 26 U.S.C. Section 411, 2026).
| Years of service | 3-year cliff (vested %) | 6-year graded (vested %) |
|---|---|---|
| 2 | 0% | 20% |
| 3 | 100% | 40% |
| 4 | 100% | 60% |
| 5 | 100% | 80% |
| 6 | 100% | 100% |
If you leave before you are fully vested, you forfeit the unvested portion of the match; under a 6-year graded schedule, leaving after 3 years lets you keep 40% and forfeit 60%. Your own contributions and their earnings always leave with you because they are 100% vested at all times.
How it interacts with 2026 contribution limits
The 401(k) employer match does not count toward the employee deferral limit but does count toward the combined annual cap, a distinction many explainers flatten. For 2026, the employee elective deferral limit under IRC Section 402(g)(1) is $24,500, and the match sits outside that number. The combined limit on all contributions to your account under IRC Section 415(c) is $72,000 for 2026, and the match does count toward that figure (Source: IRS Notice 2025-67, 2025).
| 2026 limit | Amount | Does the match count? |
|---|---|---|
| Employee elective deferral (Section 402(g)) | $24,500 | No |
| Age 50+ catch-up (Section 414(v)) | $8,000 | No (employee money) |
| Ages 60-63 higher catch-up | $11,250 | No (employee money) |
| Combined annual additions (Section 415(c)) | $72,000 | Yes |
With the standard catch-up, a saver aged 50-59 or 64+ can defer up to $32,500 in 2026 ($24,500 plus $8,000), and a saver aged 60-63 can defer up to $35,750 under the SECURE 2.0 higher catch-up (Source: IRS Notice 2025-67, 2025). Our guide on how much to convert to a Roth can help when coordinating these accounts.
True-up provisions and front-loading contributions
A true-up is an annual employer calculation that restores 401(k) employer match dollars a saver can otherwise miss by front-loading contributions. Many plans match per paycheck, so hitting the $24,500 deferral limit before December stops your deferrals, and the per-paycheck match stops with them, even when a full-year contribution would have earned a larger match. A true-up corrects that timing effect. This point is rarely explained.
Plans that offer a true-up recalculate the match after year-end and deposit any shortfall; plans without one generally do not, so spreading contributions evenly across the year can protect the full match. Because a true-up is a plan feature rather than a legal requirement, checking whether your plan offers one is a factor to weigh before front-loading.
SECURE 2.0 changes to the match
SECURE 2.0, enacted in 2022, added features that change how a 401(k) employer match can be delivered rather than the basic idea of matching. Two stand out: optional Roth employer matching and matching on qualified student loan payments. Both are plan options an employer may or may not adopt, and both are largely absent from most match explainers.
Roth employer matching
SECURE 2.0 allows plans to offer employer matching contributions as Roth (after-tax) amounts if the plan permits and you elect it. A Roth match is included in your taxable income in the year it is made, and qualified withdrawals later can be tax-free. A traditional pre-tax match is not taxed now but is taxed as ordinary income at withdrawal (Source: IRS, Matching Contributions, 2026). These Roth mechanics also matter when planning a Roth conversion strategy.
Student-loan-payment matching
SECURE 2.0 permits employers to match your qualified student loan payments as if they were 401(k) contributions, so you can build retirement savings while repaying loans. Adoption is optional for each plan, and accelerated vesting can apply to these matches (Source: 26 U.S.C. Section 411, 2026). As balances grow, coordinating match dollars with later decisions such as required minimum distributions and the net investment income tax can matter for your long-term tax picture.

Frequently asked questions
How does a 401(k) match work?
A 401(k) match works when your employer adds money to your account based on your own contributions, up to a set percentage of your salary. The IRS confirms an employer “can make matching contributions for an employee who contributes elective deferrals” (Source: IRS, 401(k) Plan Overview, 2026). Your plan’s formula sets the match rate and the pay cap.
What is a good 401(k) match?
As a general benchmark, a 401(k) employer match of 4% to 6% of pay is often described as competitive, and a match above 6% as generous. Vanguard reports an average match of 4.6% of pay in 2023 (Source: Vanguard, How America Saves 2024). The figure that matters for you is your own plan’s formula, stated in your summary plan description.
Is a 401(k) match free money?
A 401(k) match is often called free money because it adds employer dollars on top of your own contributions at no extra cost beyond contributing. In a traditional plan the match “doesn’t reduce the amount you can contribute from your salary” (Source: IRS, Matching Contributions, 2026). It becomes fully yours once you meet the plan’s vesting conditions.
What does a 50% match up to 6% mean?
A 50% match up to 6% means your employer adds 50 cents for every dollar you contribute, but only on contributions up to 6% of your salary. As an arithmetic illustration, on a $50,000 salary, contributing 6% ($3,000) earns a $1,500 match. Contributing more than 6% earns no additional match, because the match applies only up to the 6% cap.
How much should I contribute to get the full 401(k) match?
To capture the full 401(k) employer match, one approach is to contribute at least the pay percentage your plan caps the match at. For a 50%-up-to-6% formula, that means deferring 6% of pay; for a 100%-first-3%-plus-50%-next-2% formula, that means 5%. Your summary plan description states the exact cap. This is educational, not advice.
Does the employer match count toward the 401(k) contribution limit?
The employer match does not count toward the 2026 employee elective deferral limit of $24,500, but it does count toward the combined annual-additions limit of $72,000 under IRC Section 415(c) (Source: IRS Notice 2025-67, 2025). So the match is added on top of what you can defer from salary, within that overall cap.
