Investment Fee Calculator (Expense Ratio Drag)
Fees look tiny — 1% sounds like nothing. Enter your portfolio and contributions to see what that percentage actually removes from your final balance over the years.

Why a 1% fee is not 1% of your money
The fee is charged on your whole balance every year — and, worse, the fee money stops compounding for you. Over 30 years, a $50,000 portfolio with $500/month at 8% gross grows to about $1.19M at a 0.05% fee, but only about $0.98M at a 1% fee. The "tiny" 1% consumed over $200,000 — roughly 18% of your final wealth.
Fee drag compounds: net return = gross return − fee, every single year
What fees are normal?
| Product | Typical annual fee |
|---|---|
| Broad index funds / ETFs | 0.03–0.10% |
| Actively managed mutual funds | 0.5–1.2% |
| Human financial advisor (AUM) | ~1% on top of fund fees |
| Robo-advisors | 0.25% + fund fees |
| Old 401(k) plans (worst cases) | 1.5–2% all-in |
The uncomfortable evidence
Decades of SPIVA scorecards show most actively managed funds underperform their index after fees over 10–15 year periods. Paying more does not reliably buy more return — it only reliably costs more. Checking a fund's expense ratio takes ten seconds and is the highest-paid ten seconds in investing.
Frequently asked questions
How much does a 1% fee cost over 30 years?
On a $50,000 start plus $500/month at 8% gross, about $200,000+ versus a 0.05% index fund — nearly a fifth of your final balance. Run your own numbers above.
What is an expense ratio?
The annual percentage a fund charges on assets, deducted invisibly from returns. 0.05% means 50 cents per $1,000 per year; 1% means $10 per $1,000 — every year, on a growing balance.
Is a financial advisor worth 1%?
For investment selection alone, rarely — low-cost index portfolios beat most managed alternatives after fees. Advisors can earn their fee on tax planning, estate work, and stopping panic-selling; flat-fee or hourly advisors deliver that without the compounding drag.
How do I find my total fee?
Add every layer: fund expense ratios (in the fund fact sheet), advisor AUM fee, platform/account fees, and for 401(k)s the plan administration fee (in the annual fee disclosure).
