Marsh McLennan filed two Form 11-K reports for plan year 2025, of which one has been read. The other report has not, so this page cannot say what the plan it covers pays.

What Marsh McLennan puts in, and what the plan costs
What Marsh McLennan put into the plan, per active participant
$8,635
Marsh & McLennan Companies, Inc. put $8,635 into this plan for each of its 17,704 active participants in plan year 2024. This is the whole employer side of the plan: matching money, profit sharing, non-elective and safe-harbor contributions, and reallocated forfeitures. The Form 5500 does not separate them, so this is what the employer put in and not the match.
Marsh McLennan put in more per active participant than 87% of plans with 5,000+ participants in insurance. The middle plan in that group of 98 reported $5,049. Insurance comes from business code 524210, which Marsh McLennan entered on its own Form 5500. Sponsors pick that code themselves, so a code that does not describe what the employer does ranks the plan against the wrong companies.
Matched to this employer by sponsor name, not by an identifier stated in the filing. This record could cover another plan of the same employer.
What this figure cannot separate: how much Marsh McLennan pays, and how much it puts in
This is dollars, not a rate. A Form 5500 carries no payroll, so the figure reflects both how much the employer puts in and how much the employer pays: two plans running the same formula report different amounts when one pays better. Crossing the peer group with industry holds most of that difference still, and none of it disappears.
This is one plan year, not an average. A true-up, a plan merger or a one-off contribution moves a single year on its own.

The $8,635 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. Marsh & McLennan Companies, Inc. also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $1,485 a year at a $49,500 salary, and the same filing states employer contributions made outside the match. That second figure is what the formula pays one worker on that salary, and not an amount either filing reports. The two figures cover different plan years and measure different things, so neither one is the other one corrected.
What Marsh McLennan puts in
$1,485
a year, at a $49,500 salary.
The match paragraph, word for word
“The Company makes matching contributions, after completion of 1 year of vesting service, of 50% on the first 6% of eligible compensation (base pay) that participants contribute to the Plan in any pay period. The Company makes an automatic Company contribution equal to 4% of eligible base pay, (the "Fixed Contribution"). Eligible U.S. employees of the Company are eligible to receive the Fixed Contribution with the exception of MMA. The Fixed Contribution is paid into the Plan by the Company regardless of whether an employee contributes to the Plan.”
What you contribute to collect all of it
Contribute at least 6% of your pay to collect the full match.
That is $2,970 a year at a $49,500 salary, and it scales with your own.
Vesting score
57.14 out of 100
How fast the employer’s money becomes yours. Higher than 4% of the 253 schedules we have scored.
It measures vesting speed and nothing else. It says nothing about the size of the match, what the plan charges, or the funds inside it.
Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 0%, 0%, 33.33%, 66.67%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“Participants are vested immediately in their own contributions plus actual earnings thereon. Participants hired before January 1, 1998 are fully vested in the Company’s matching contributions. Participants hired on or after January 1, 1998 and who terminated employment with the Company on or before June 30, 2002 vested in the Company’s matching contribution as follows: 0% if less than 3 years of service, 33% after 3 years of service, 67% after 4 years of service, and 100% after 5 years of service. Participants who were hired on or after July 1, 2002 and who terminated employment with the Company on or before December 31, 2005, were subject to the following vesting schedule: 0% if less than 2 years of service, 20% after 2 years of service, 40% after 3 years of service, 67% after 4 years of service and 100% after 5 years of service. Participants who were active employees as of January 1, 2006, or participants who terminate employment on or after January 1, 2006 who have at least 1 hour of service on or after January 1, 2006, vest in the Company’s matching contribution and Fixed Contribution as follows: 0% if less than 2 years of service, 33-1/3% after 2 years of service, 66-2/3% after 3 years of service and 100% after 4 years of service.”
A worker hired today collects no match for 1 year. This is a filed term, and it does not move the score above.
Eligibility, word for word
“In accordance with the Plan provisions, employees who are at least 18 years of age and classified as a United States (U.S.) regular or temporary employee, paid from U.S. payroll, and who are employees of any subsidiary or affiliate of Marsh & McLennan Companies, Inc. (the "Company", "Marsh" or the "Plan Sponsor"), with the exception of any employee of Marsh & McLennan Agency LLC and its subsidiaries and affiliates ("MMA"), are eligible to contribute to the Plan.”
The wait before the match starts and the year-end true-up appear above when the filing states them. Neither is part of the score, and a filing that is silent on one of them is not a plan without it.
What the plan costs, against plans of its size
Not reported
The Form 5500 filing does not report the plan-paid administrative expenses this figure needs.
What is Marsh McLennan's 401(k) match formula?
Marsh McLennan's 401(k) employer match tops out at 3% of pay. The match is deposited each payroll. One rate up to one limit is the commonest of the four shapes a match formula takes.
| Match formula | 50% of the first 6% of pay |
|---|---|
| Maximum employer match | 3% of compensation |
| Deposited | Each payroll |
| Paid in company stock | No, paid in cash or per your investment elections |
| Conditions | Matching contributions begin after completion of 1 year of vesting service; the match applies to eligible compensation (base pay) contributed in any pay period |
| Other employer contribution | Automatic Fixed Contribution equal to 4% of eligible base pay, paid regardless of whether the employee contributes to the Plan (not available to MMA employees) |
At a $60,000 salary, contributing 6% ($3,600) earns the full employer match of $1,800 for the year.

What is Marsh McLennan's 401(k) vesting schedule?
Marsh McLennan vests the employer match on a graded schedule: 33.33% after two years, rising to 100% after four. Each step is money that leaves with you that year, which is how a graded schedule differs from a cliff.

|---|---|
| Your own contributions | Immediate: always 100% yours |
| Accelerated vesting | Participants hired before January 1, 1998 are fully vested in Company matching contributions; participants who terminated before 2006 remain subject to legacy 5-year schedules |
| Other employer contributions | The Fixed Contribution vests on the same schedule as the Company matching contribution (0% below 2 years, 33-1/3% after 2 years, 66-2/3% after 3 years, 100% after 4 years of service) |
