I know a Principal Engineer making $450K total comp.
A brilliant, senior level, who manages a team of 15, makes complex architectural decisions worth millions.
But his 401(k) contribution? $0.
"I've got RSUs vesting every quarter. I'm good on retirement."
Not really, you're leaving $10K+ on the table every year.
Here's the math he wasn't running:
His company matches 50% on the first 4% of contributions. For someone at his comp level, that's roughly $9,000-10,000 in free money annually.
He's been there 6 years. That's $60K he just didn't take. Plus the compound growth he missed on that $60K.
Over a 10-year career? He could've potentially walked away from $100K+ in matching alone.
This isn't advanced optimization. It's basic math.
Why do high earners skip the 401(k)?
I see three reasons:
1. "I've got equity, I don't need it"
RSUs are great. But they're not a retirement account. They're taxed as income when they vest. They're concentrated in one stock. And if you leave or get laid off, unvested RSUs disappear.
A 401(k) is tax-deferred, has multiple investments to diversify funds, and it's yours no matter what happens at work.
They're not interchangeable.
2. "I'll do it later when I have more time"
There's never a perfect moment. Meanwhile, the match you're not getting this year is gone forever. You can't go back and claim it later.
3. "It's complicated, I'll figure it out eventually"
It takes 20 minutes to set up, nothing too complex.
The real cost of skipping the match:
Let's say you're 35, making $200K base, and your company matches 50% on 4%. That's $4,000/year in free money.
If you contribute nothing for 10 years:
●You: $0
●Company: $0
●Total: $0
If you contribute enough to get the match for 10 years at 7% growth:
●You: $55,000
●Company: $55,000
●Growth: $22,000
●Total: $132,000
You left $132K on the table because you didn't spend 20 minutes setting it up.
"But I'm saving in other ways"
Great, keep doing that. But the 401(k) match is literally free money with a guaranteed 50% return.
You're not beating that with stock picks, crypto, or real estate. It's the easiest financial decision you'll ever make.
I get it, when you're making $300K, $400K, $500K, a few thousand in 401(k) matching doesn't feel urgent.
But that's $10K/year you're turning down. Over a career, it's $250K-500K+ with growth.
RSUs are great, but they're not a substitute for tax-deferred retirement savings with free matching.
Take the free money.
