I Turned Down Free 401k Money for Seven Years — $21,090 Gone

I opted out of the 401k at 24. The match was 100 percent up to 5 percent. Missed match over seven years: $15,635. Grown at 9 percent, it is $21,090. I am enrolled at 10 percent now. The opt-out language still stings.

Thirty-one years old, seven weeks into a new job, and it took a benefits portal and a Sunday night to make me count what the old one cost me. May 3, 7:30 p.m., couch, laptop on my knees, cat on the armrest, spreadsheet open with my own salaries typed into it, 2019 thru 2025. The right-hand column said MATCH MISSED. The total at the bottom did not get modest when I blinked.

Numbers make the stakes stop being abstract, so here are mine. $21,090 is fourteen months of my rent at $1,495. It is more than my 2016 Corolla is worth on any lot in town. It is most of the down payment I do not have at 31, missing from the account that was sposed to hold it.

The form that began all this was one page long, and I can still recite the sentence I initialed at 24: I elect to defer enrollment in the company retirement plan. Ten words, one checkbox, and I was sure I knew what the market was for.

the packet was twenty-two pages

Reno, 2019, first real job, a parts distributor paying $38,500 a year. The benefits packet ran 22 pages and the match was 100 percent of the first 5 percent, which came to $160 a paycheck of free money. Rent on Fourth Street: $1,450. Car payment: $315. My mother watched her 401k drop 40 percent in 2008 and still keeps that statement with the red numbers in a drawer, and I was 24 with her statement in my head instead of the match table in front of me. I checked defer. I kept the $160. I remember what I did with it and it was not investing.

what the match actually was

The arithmetic, for anyone who wants to see the machinery: 100 percent of 5 percent, year after year, on the salaries I actually earned. 2019: $1,925. 2020: $1,990. 2021: $2,060. 2022: $2,200. 2023: $2,345. 2024: $2,485. 2025: $2,630. The plan ran thru Empower, and everyone who enrolled sat in a target-date fund made mostly of index funds with a 0.04 expense ratio. I missed $15,635 of free money across seven years, every dollar of it matched, none of it taxed goin' in, all of it handed to people who never opened the packet twice.

the 2020 dip I watched from the sideline

March 2020 made me feel smart for about six weeks. The market fell 34 percent, every headline used the word crash, and my mother called to say thank God you never put money in that thing. Then the market rose 70 percent off the bottom without me, and the S&P 500 has approximately doubled since, and nobody felt smart by 2022. I was still telling the 401k story at barbecues the whole time, the one about the crash, and it was already outta date when I told it.

back in at thirty-one

The new job is a hospital system, and enrollment is automatic at 6 percent unless you opt out, which is the whole trick, because doing nothing is now the correct move and doing somethin' was always my talent. I set mine to 10 percent. The default fund is an index fund that tracks the whole market at a 0.02 expense ratio, and I read all 19 pages of this packet too, because I have a history with packets.

the two thousand at fidelity

While I was in there, HR pointed me to the 401k rollover form for a $2,270 account I left sitting at Fidelity in 2018, from a call-center year I do not bring up at parties. The rollover took eleven minutes online and the account had gone exactly nowhere in eight years. Two thousand two hundred seventy dollars, one decade of dividends, a balance that grew like a houseplant in a dark closet. It is in the new plan now, next to money that finally has a match behind it.

the spreadsheet math i ran three times

Back to the number in the title, cuz I owe you the work. $15,635 of missed match, invested at the index fund's 9 percent long-run average, compounds to about $21,090 by this month, depending on the exact days you assume. I ran it three times: once on the couch, once at the kitchen counter, once on my phone while the cat knocked a pen off the armrest. At 6 percent it comes out near $19,500. At 11 percent it is worse than the title. It does not get slight, which I imagine is the point of compounding, working exactly as advertised on money I never put in.

what i did about it

You cannot invoice the past. I asked, May 5, politely, and HR confirmed there is no make-up contribution for money you never deferred. So the honest list is short: enrolled at 10 percent, set the annual escalator to add a point every January, and wrote $21,090 on a sticky note inside my desk drawer at home where I keep the stamps. The cat has already knocked one stamp off the roll. The number stays.

the checkbox language

The old Reno portal still lets me log in, and the enrollment history page still shows my election from September 2019: DEFERRED, 0 percent, effective immediately, initials and date. At 31 it took ninety seconds of clicking to say 10 percent and be done. That is the entire distance between those two forms, ninety seconds, seven years. I ran the math one more time this mornin', May 11. It did not get slight.
