How to Fix 401(k) High Fees in 1 Hour & Save $100K as a 40-Year-Old Parent

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.
