What Duke Energy puts in, and what the plan costs

What Duke Energy put into the plan, per active participant

$9,486

Duke Energy Corporation put $9,486 into this plan for each of its 26,616 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.

0 · least per person100 · most per person

Duke Energy put in more per active participant than 87% of plans with 5,000+ participants at utilities. The middle plan in that group of 39 reported $5,837. Utilities comes from business code 221100, which Duke Energy 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.

What this figure cannot separate: how much Duke Energy 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 $9,486 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. Duke Energy Corporation also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $2,970 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 Duke Energy puts in

$2,970

a year, at a $49,500 salary.

The match paragraph, word for word
The Participating Company generally matches 100% of the first 6% of the employee’s eligible compensation that is contributed to the Plan in the form of pretax and/or Roth 401(k) contributions. A different matching contribution formula may apply to certain groups of employees covered by a collective bargaining agreement. Participant after-tax contributions and matching contributions are intended to satisfy the requirements of Section 401(m) of the IRC. The Participating Company also provides (i) a non-elective employer retirement contribution of 4% of eligible compensation for employees who are not eligible to participate in a defined benefit plan and (ii) discretionary prevailing wage contributions in amounts required to meet prevailing wage/benefit levels for employees subject to prevailing wage requirements.

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.

Vesting scheduleImmediate

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
A participant is 100% vested in their Plan account balance attributable to employee and company matching contributions (and earnings on those contributions). Employer retirement contributions and associated investment earnings are subject to a three-year vesting requirement and also vest, if, while employed, the employee dies, becomes disabled or attains age 65. Prevailing wage contributions and associated investment earnings are also subject to a three-year vesting requirement and also vest, if, while employed, the employee dies, becomes disabled or attains age 65.

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.
