A 50%-of-6% match on $80,000 is $2,400, and half is easy to lose

The 2026 401(k) deferral cap is $24,500. The match depends on the plan formula, the paycheck pattern and the vesting clock. The arithmetic, with sources.

What happened
The IRS set the 2026 401(k) elective deferral limit at $24,500 on November 13, 2025, with an $8,000 catch-up at 50 and over and an $11,250 catch-up at ages 60 to 63. The overall limit on all contributions is $72,000. None of those figures says what an employer adds; that is set by each plan's match formula and vesting schedule.
Why
A match is a percentage of what the employee defers, up to a ceiling expressed as a percentage of pay. Most plans compute it paycheck by paycheck, so the timing of deferrals changes the dollars received. Employer money then vests on a schedule of up to three years (cliff) or six years (graded) before it belongs to the employee.
The numbers that matter
$24,500401(k) elective deferral limit, 2026 (IRS, Nov 13, 2025)
$2,400Annual match on an $80,000 salary at 50% of the first 6% deferred (calculation)

Why it matters
On an $80,000 salary a 50%-of-6% match is worth 3% of pay, or $2,400 a year, and it can be halved by a 3% deferral, missed by front-loading, or forfeited by leaving before the cliff.
What happens nextas we saw it on 29 Oct 2026
The IRS publishes the 2027 limits in a November notice each year; the 2026 figures came in IR-2025-111 on November 13, 2025. The mandatory Roth catch-up rules in the final regulations apply to taxable years beginning after December 31, 2026.

401(k) match
Employer match on an $80,000 salary at 50% of the first 6% deferred, 2026 plan year

The match tops out at 3% of pay once the employee defers 6%; below that, every point of deferral left out costs $400 of employer money.

Go deeper

An employer that matches half of the first 6% of pay is offering 3% of salary, every year, on one condition: the employee has to put in 6% first. On an $80,000 salary that is $2,400 a year of employer money. A worker who defers 3% collects $1,200 of it. A worker who defers 6% but reaches the $24,500 federal cap in June may, depending on the plan, collect less than $1,500. And a worker who leaves after two and a half years under a three-year cliff can collect none of it.

None of those outcomes appears in the IRS limits. The limits cap what goes in; the match formula, the paycheck pattern and the vesting schedule decide what the employer side is worth. The age-by-age limits themselves are covered in the retirement limits piece.

The 2026 limits: $24,500, $8,000, $11,250 and $72,000

Data
The elective deferral limit is $24,500 for 2026, up $1,000
IRS news release IR-2025-111 of November 13, 2025 states that “the amount individuals can contribute to their 401(k) plans in 2026 has increased to $24,500, up from $23,500 for 2025.” The catch-up at 50 and over “is increased to $8,000, up from $7,500 for 2025.” At 60 to 63 the higher catch-up “remains $11,250.” Notice 2025-67, the underlying cost-of-living notice, puts the section 415(c) limit on all contributions at $72,000 for 2026, up from $70,000, and the compensation a plan may count at $360,000, up from $350,000.

The IRS page on 401(k) contribution limits, last reviewed April 8, 2026, restates the overall limit as “$72,000 in 2026 ($80,000 including catch-up contributions or up to $83,250 for those age 60 to 63).” The $47,500 gap between $24,500 and $72,000 is the room for employer money: matching, profit sharing and any after-tax contributions a plan allows. On an $80,000 salary a 50%-of-6% match uses $2,400 of it.

The $80,000 example: $2,400 on offer, $1,200 left behind at 3%

A match has two numbers: the rate and the ceiling. “50% of the first 6%” means the employer adds 50 cents for every dollar deferred until the deferral reaches 6% of pay, then stops. The same plan could be described as “3% of pay, conditional on a 6% deferral”, which is the clearer way to think about it.

Data
In BLS survey data, six in ten savings-and-thrift participants had a match up to a specified percentage of earnings, and half of those plans capped the match at 6%
The BLS article “Defined contribution retirement plans: Who has them and what do they cost?” (Beyond the Numbers, Vol. 5 No. 17, December 2016) reports that in 2015, 62% of savings and thrift plan participants were in plans where “the employer matched up to a specified percentage of employee earnings.” Of those plans, one-half matched “up to 6 percent of employee contributions (or earnings)”, and the rest had “lower contribution ceilings, typically 3 percent or 4 percent of earnings.” The BLS puts its 2022 match detail in spreadsheets that were not readable for this piece, so 2015 is the latest figure quoted.
Wealth Signal calculation
At 6% the worker defers $4,800 and the employer adds $2,400; at 3% the match halves
Salary $80,000. Deferral at 6%: $80,000 × 0.06 = $4,800. Match: 50% × $4,800 = $2,400, or 3.0% of salary. Deferral at 3%: $2,400. Match: $1,200. Difference: $1,200 a year of employer money not collected. A 10% deferral is $8,000 from the employee, but the match is still $2,400, because the ceiling is 6% of pay, not 6% of the deferral.

Source: calculation. Deferral limit from IRS IR-2025-111, November 13, 2025. $24,500 ÷ $80,000 = 30.6%. Assumes the match is paid on every paycheck and the worker defers evenly all year.

The BLS automatic-enrollment fact sheet of April 13, 2023 shows why the 3% row matters: in 2022, 42% of private industry workers in savings and thrift plans had automatic enrollment, and the median default contribution was 3% of earnings. A worker left at a 3% default under a 50%-of-6% formula sits in the second row of the table.

Vesting: the employer's money is not yours until the clock runs

Fact
Employee deferrals are always 100% vested; employer money may vest on a cliff of up to three years or a graded schedule of up to six
The IRS page “Retirement topics — vesting”, last reviewed April 8, 2026, states that “An employee's own contributions to the plan” are always fully vested. For employer contributions the plan document chooses the schedule. Under cliff vesting the employee owns 0% of employer money until a point no later than the end of the third year of service, then 100%. Under graded vesting the employee is at least 20% vested after two years, gaining 20 points a year to reach 100% no later than six years. A year of service is generally 1,000 hours in 12 months, “as defined by the plan.” Unvested amounts “may be forfeited by employees when they are paid their account balance or when they don't work more than 500 hours in a year for five years.”
Wealth Signal calculation
Leaving after 2.5 years under a 3-year cliff forfeits $6,000 of match on the $80,000 example, before any investment return
Match of $2,400 a year × 2.5 years = $6,000 of employer contributions at 0% vested. The employee's own $4,800 × 2.5 = $12,000 is fully vested and leaves with them. Gains or losses on the $6,000 go with it and are excluded here. Under a six-year graded schedule at the IRS minimum, the same worker at 2.5 years is 20% vested: $1,200 kept, $4,800 forfeited. Six months later, at three years, the cliff worker keeps all $7,200 and the graded worker 40%, $2,880.
Data
In the last BLS breakdown, 31% of savings-and-thrift participants had immediate vesting, 26% cliff and 34% graded
The BLS article “Selected characteristics of savings and thrift plans for private industry workers” (Beyond the Numbers, July 2015, 2012 data) reports those shares, with 9% not determinable. The cliff share rose from 18% in 2009.

Hitting the cap early: the per-paycheck arithmetic

A plan that calculates the match each pay period, on that period's pay and deferral, sets a trap for anyone who reaches $24,500 before the last paycheck of the year. The deferral stops because the law requires it, and the match stops with it, because there is nothing to match.

Wealth Signal calculation
Front-loading to the cap by the 16th of 26 paychecks costs $923 of match in a plan without a true-up
Salary $80,000 over 26 paychecks is $3,076.92 per paycheck. The full match in any period is 50% × 6% × $3,076.92 = $92.31; over 26 periods, $2,400. Suppose the worker defers 50% of pay, $1,538.46 a period. After 15 periods the total is $23,076.92; the 16th deferral is capped at $1,423.08 to reach $24,500. Match collected: 16 × $92.31 = $1,476.92, since the match is capped at 6% of pay each period however large the deferral. Periods 17 to 26 have no deferral and no match: 10 × $92.31 = $923.08 not received, 38.5% of the match. Deferring $942.31 a period, 30.6% of pay, reaches $24,500 at the 26th paycheck and collects the full $2,400.

Some plans fix this with a “true-up”: a year-end employer contribution that brings the match up to what the formula would have paid on annual pay and annual deferrals. Whether a plan does this is set in the plan document, not by law, and this article makes no claim about how many plans offer one. A worker who cannot find the word in their summary plan description can assume the per-period arithmetic applies.

Catch-up at 50 and the $11,250 window at 60 to 63

Wealth Signal calculation
The maximum employee deferral at ages 60 to 63 is $35,750 and the maximum total is $83,250
$24,500 + $11,250 = $35,750 of employee deferrals for someone who turns 60, 61, 62 or 63 in 2026. At 50 to 59, and again at 64 and over, it is $24,500 + $8,000 = $32,500. The IRS states the overall limit as $72,000 “($80,000 including catch-up contributions or up to $83,250 for those age 60 to 63)”, which is $72,000 + $8,000 and $72,000 + $11,250: catch-up contributions do not count against the $72,000.
Fact
From 2027, catch-up contributions by higher earners must be Roth, with the wage test set at $150,000 for 2025 wages
Treasury and the IRS issued final regulations on the SECURE 2.0 Roth catch-up rule in IR-2025-91 on September 15, 2025, published in the Federal Register on September 16, 2025 (TD 10033, 90 FR 44527). The rule covers a participant whose FICA wages from the employer sponsoring the plan for the prior year “exceeded $145,000”, indexed; Notice 2025-67 states that the Roth catch-up wage threshold for 2025 “is increased from $145,000 to $150,000.” The final rules “generally apply with respect to contributions in taxable years beginning after December 31, 2026,” with a “reasonable, good faith interpretation standard” before then. In plain terms, an affected worker's catch-up dollars go in after tax rather than before. The requirement touches the catch-up only, not the $24,500 base deferral and not the match.

What it means for your money

Four lines in a plan document settle most of it, and each has a dollar value on the $80,000 example.

  1. The ceiling. 6% here. Every point of deferral below it leaves $400 of employer money uncollected.
  2. The timing. Per-paycheck match, with or without a true-up. Without one, $24,500 spread over 26 paychecks collects $2,400; front-loaded into 16, $1,476.92.
  3. The clock. A three-year cliff: leaving at 2.5 years forfeits $6,000 of match; leaving at 3.0 years forfeits nothing.
  4. The age. The employee cap is $32,500 at 50 and $35,750 at 60 to 63; from 2027 the catch-up must be Roth for anyone over the wage threshold.

None of this says how much anyone should defer. It says what the formula pays for each choice, and that the employer side of a 401(k), which looks like a fixed benefit, is a function of variables the employee partly controls. The after-tax question behind the Roth rule is worked through in the Roth conversion piece and the backdoor Roth piece; what $2,400 a year becomes over decades is compound growth; the withdrawal end is in the RMD piece.

This article does not claim that any particular employer uses a 50%-of-6% formula, a three-year cliff or a per-paycheck match without a true-up; those are worked examples, and the plan document governs. The BLS figures are from survey years 2015 (match ceilings), 2012 (vesting) and 2022 (automatic enrollment), not 2026. The Roth catch-up summary omits exceptions, including later dates for governmental and collectively bargained plans. The calculations exclude investment returns, taxes and fees. Nothing here is tax or financial advice.
