Step-by-Step Examples
Example 1
1% Advisory Fee
$10k initial, $5k/yr, 8% return, 1% fee, 30 years.
- Without fees: ~$704,000
- With 1% fee (7% net): ~$530,000
- Fee cost: ~$174,000 (25% of potential wealth)
- This is why low-cost index funds matter enormously
✓ ~$174,000 lost to 1% fee
Example 2
Fund Selection
$50k initial, $6k/yr, 7% return, 0.8% vs 0.04% fee, 25 years.
- High fee 6.2% net: ~$620,000
- Low fee 6.96% net: ~$660,000
- Difference: ~$40,000
✓ ~$40,000 saved by choosing lower fees
Example 3
Near-Zero Fees
$25k, $3.6k/yr, 8%, 0.04% fee, 30 years.
- Difference from 0% fee: only ~$2,000
- Vanguard/Fidelity index funds are essentially free
✓ Nearly zero fee drag at 0.04%

Common Mistakes to Avoid
⚠️
Dismissing small fee differences
0.04% vs 1% on $500k is $4,800/year compounding for decades — not trivial.
⚠️
Not checking 401k expense ratios
Many plans include 0.5–1.5% funds. Choose the lowest-cost index option available.
⚠️
Assuming fees equal quality
Data consistently shows low-cost index funds outperform high-fee active funds after fees.
Frequently Asked Questions
What is an expense ratio? ▾
Annual fee as a % of investment, auto-deducted from returns. 1% on $100k = $1,000/yr regardless of performance.
Good expense ratio? ▾
Index funds: 0.03–0.20% (excellent). Actively managed: 0.5–1.5%. Avoid over 1% without strong justification.
Robo-advisor fees? ▾
Typically 0.25–0.50% on top of fund fees. Reasonable for hands-off investors.
Financial advisor fees? ▾
Fee-only: 0.5–1% AUM, or flat/hourly. AUM on large portfolios can cost $100k+ in foregone wealth.
Transaction fees? ▾
Most major brokerages eliminated stock/ETF trading commissions. Watch the fund expense ratio instead.
