Red Flag 1: You Don’t Know Your Fund Expense Ratios

If you’ve never looked up your 401k fund expense ratios, you may be paying 10–40× more than necessary. Log in now and check. Above 0.5% for any actively managed fund warrants consideration of alternatives. Above 1.0% for any fund is almost certainly too expensive.

Red Flag 2: Your Balance Is Far Below Age Benchmarks

Fidelity benchmarks: 1× salary at 30, 3× at 40, 6× at 50. If you’re more than 30% below these targets, your current contribution rate isn’t enough. Run the calculator to determine what rate would close the gap by retirement.

Red Flag 3: You’re in a Money Market or Stable Value Fund at 35

A 35-year-old in a money market fund earns 2–4% when they should be earning 7–10% in equities. On $100,000, the 30-year difference between 3% and 7% return is $424,000 vs. $761,000 — a $337,000 loss from allocation alone.

Red Flag 4: You Have Multiple Old 401k Plans Left Behind

The average American has left $5,400 in orphaned 401k plans from past employers. These accounts may have high fees, investments that have drifted, and no attention. Consolidate all old plans into your current employer’s plan or a rollover IRA.

Red Flag 5: Your Contribution Hasn’t Increased in 3+ Years

If you’re earning more than you were 3 years ago but contributing the same percentage — congratulations, you’ve given yourself a raise. The contribution rate should ideally increase each year. If it hasn’t, enable auto-escalation today.

⚠️The Stale-Rate Trap

Contributing 6% of $55,000 in 2020: $3,300/year. Contributing the same 6% of $75,000 in 2025: $4,500/year. But contributing 10% of $75,000: $7,500/year. The stale-rate investor contributes $4,500; the rate-optimizer contributes $7,500. Over 25 years at 7%, that $3,000 annual gap = $204,000 in retirement wealth.
