Hey, if you’re in your 40s juggling work, kids, and that mortgage, that 401(k) you set up years ago is probably just sitting there—quietly losing you over $100,000 to high fees and crappy default funds.
You think it’s “fine,” but it’s not. Most parents like us don’t even know it’s happening. In this guide, I’ll walk you through my 1-hour fix: spot the problem, make one smart switch, and automate it so you reclaim family time without the guilt.
The Silent $100K Killer in Your 401(k)
Picture this: A dad like Mark—42, two kids, $120K salary. His 401(k) shows $60K. Solid, right? Wrong. We logged in, and it was parked in a “Target Date 2050 Fund” with a 0.9% expense ratio.
That “tiny” fee? Over 25 years, it eats $100K+ of your growth. Target date funds sound safe, but they charge 20x more than index funds and stuff in bonds you don’t need yet.

Fees + over-diversification = slow leak. Your money works for Wall Street, not your family.

|---|---|---|
| Target Date 2050 | 0.9% | $100K+ lost |
