Cummins' Form 11-K filing for plan year 2025 describes two separate 401(k) plans. The terms on this page are read from the Cummins Retirement and Savings Plan. Not all of them state a match formula, so each one is listed below with the group it covers and what its filing says.

One row per plan, taken from the Form 11-K report this site has read for the plan year ended December 31, 2025. Each maximum comes from that plan’s own filing and describes only that plan.
What Cummins puts in, and what the plan costs
What Cummins put into the plan, per active participant
$3,894
Cummins Inc. put $3,894 into this plan for each of its 28,337 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.
Cummins put in more per active participant than 54% of plans with 5,000+ participants in industrial and materials manufacturing. The middle plan in that group of 178 reported $3,585. Industrial and materials manufacturing comes from business code 333610, which Cummins 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 Cummins 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 $3,894 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. Cummins Inc. also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $1,733 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 Cummins puts in
$1,733
a year, at a $49,500 salary.
The match paragraph, word for word
“For the RSP, the Company matches participant contributions at 100 percent of the first 1 percent of participant’s eligible wages contributed plus 50 percent of the next 5 percent contributed. Additionally, the Retiree Medical contribution is a flat, one time dollar contribution that the employer makes annually to the RSP after an employee has completed two years of service to the Company.”
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
100 out of 100
How fast the employer’s money becomes yours. Higher than 48% 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: 100%, 100%, 100%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“Participants are fully vested in all employee and employer contributions and earnings thereon at all times.”
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 Cummins' 401(k) match formula?
Cummins' 401(k) employer match tops out at 3.5% of pay. A tiered formula pays its best rate on the first slice of pay and less on the next, which is how the rate steps down.
| Match formula | 100% (dollar-for-dollar) of the first 1% of pay |
|---|---|
| then | 50% of the next 5% of pay |
| Maximum employer match | 3.5% of compensation |
| Paid in company stock | No, paid in cash or per your investment elections |
| Other employer contribution | Retiree Medical contribution: a flat, one-time dollar contribution the employer makes annually to the RSP after an employee has completed two years of service to the Company |
At a $45,000 salary, contributing 6% ($2,700) earns the full employer match of $1,575 for the year.
What the filing says, word for word
“For the RSP, the Company matches participant contributions at 100 percent of the first 1 percent of participant’s eligible wages contributed plus 50 percent of the next 5 percent contributed. Additionally, the Retiree Medical contribution is a flat, one time dollar contribution that the employer makes annually to the RSP after an employee has completed two years of service to the Company.”

What is Cummins' 401(k) vesting schedule?
Cummins vests the employer match immediately: 100% is yours as soon as it is paid in. Nothing is forfeited when you leave, which is not true of the two schedules that vest over time.
| Employer match vesting | Immediate: employer match is 100% vested when contributed |
|---|---|
| Your own contributions | Immediate: always 100% yours |
| Other employer contributions | Participants are fully vested in all employee and employer contributions and earnings thereon at all times |

Who can join Cummins' 401(k), and is enrollment automatic?
Cummins' filing does not mention automatic enrollment, which is not the same as the plan having none.
| Plan entry | Eligible employees are salaried and non-bargaining hourly employees of the Company, as well as union employees who have harmonized their benefits with the Plan |
|---|---|
| Excluded groups | Bargaining unit employees whose units have not harmonized benefits with the RSP (certain bargaining unit employees are covered by the separate Certain Bargained RSP) |
| Automatic enrollment | Not mentioned in the filing (not proof of absence) |
Eligibility, word for word
“For the RSP, eligible employees are salaried and non-bargaining hourly employees of the Company, as well as union employees who have harmonized their benefits with the Plan. For the Certain Bargained RSP, eligible employees are certain bargaining unit employees of the Company.”
