Maximum employer match, as a share of pay

What 1st Source puts in, and what the plan costs

What 1st Source put into the plan, per active participant

$4,440

1st Source Corporation put $4,440 into this plan for each of its 1,196 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

1st Source put in more per active participant than 68% of plans with 1,000–4,999 participants at holding companies. The middle plan in that group of 157 reported $2,643. Holding companies comes from business code 551111, which 1st Source 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 1st Source 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 $4,440 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. 1st Source Corporation also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $2,475 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 1st Source puts in

$2,475

a year, at a $49,500 salary.

The match paragraph, word for word
“Matching Contribution — contribution is discretionary. The first 4% of a participant's eligible compensation contributed to the Plan is matched 100%, and the next 2% of a participant's eligible compensation contributed to the Plan is matched 50%.”

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

47.14 out of 100

How fast the employer’s money becomes yours. Higher than 3% of the 369 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 scheduleGraded, full at 5 years

Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 0%, 10%, 20%, 40%, 60%, 100%, 100%. The score is the average of those 7 readings.

Vesting, word for word
“Vesting of the 1st Source Employer Contributions, including match, fixed profit sharing, discretionary profit sharing, and regular contributions, is based on years of credited service. A credited year of service is at least 1,000 hours worked in a 12-month period. A participant is 10%, 20%, 40%, 60%, or 100% vested after completing one, two, three, four, or five or more years of credited service, respectively.”

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.

The formula, the six-year window and a worked example

What the plan costs, against plans of its size

71st percentile

$119.23 per participant in plan-paid administrative cost, more expensive than 71% of plans with 1,000–4,999 participants.

What is 1st Source's 401(k) match formula?

1st Source's 401(k) employer match tops out at 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 formula100% (dollar-for-dollar) of the first 4% of pay
then50% of the next 2% of pay
Maximum employer match5% of compensation
ConditionsThe matching contribution is labeled discretionary; employer contributions are provided to eligible full-time participants and may be made in cash or shares of 1st Source common stock
Other employer contributionFixed Profit Sharing Contribution: 2% of eligible annual compensation
Other employer contributionDiscretionary Profit Sharing Contribution: 1% of 1st Source's net profit awarded to eligible participants, determined annually by the Board of Directors
Other employer contributionRegular Contribution: discretionary, determined annually by the Board of Directors

At a $75,000 salary, contributing 6% ($4,500) earns the full employer match of $3,750 for the year.

What the filing says, word for word
“Matching Contribution — contribution is discretionary. The first 4% of a participant's eligible compensation contributed to the Plan is matched 100%, and the next 2% of a participant's eligible compensation contributed to the Plan is matched 50%.”

1st Source vests the employer match on a graded schedule: 10% after one year, rising to 100% after five. Each step is money that leaves with you that year, which is how a graded schedule differs from a cliff.

The plan assets, the participant counts, the plan-paid fees and the recordkeeper come from a different document, the plan’s DOL Form 5500 annual return, and the section that reports them links it. Comparisons with other employers are computed across the filings named in the section they appear in.
