The expense ratio is the fee that never appears on a statement: a percentage of everything you hold, deducted inside the fund's net asset value every single night. A 1% fund on a $50,000 balance quietly takes about $500 in year one - but the real bill is bigger, because every dollar skimmed also misses decades of compounding. That second-order cost is what the calculator above prices.
The gap between fund classes is enormous and stable: broad index funds run near 0.03%, active funds average near 1%, and the SEC's investor education materials are blunt that fees may seem small but over time they can have a major impact. Whether the active fund earns its fee is unknowable in advance; what the fee costs is arithmetic, and the arithmetic is above.
How to use
- Find the fund's expense ratio in its prospectus fee table - listed as a percentage of assets per year.
- Enter your balance, the ratio, your realistic holding years and the return you expect before fees.
- Compare the fee column against a 0.03% index alternative - that spread is the decision.
Frequently asked questions
What does a 1% expense ratio actually cost?
On a $50,000 balance earning 7% for 20 years, about $33,000 in removed gains versus a zero-fee alternative - roughly a sixth of what the portfolio would have been. The first-year fee is only about $500; the rest is compounding the fund never got to do.
Is the expense ratio deducted from my account?
Not as a visible line - it comes out of the fund's net asset value, so your reported return is already after fees. That is why the fee feels free and why you have to compute the counterfactual yourself: the dollars that never arrived never show up as a charge.
What is inside the expense ratio?
Management fees, administrative costs, and sometimes 12b-1 marketing fees - everything the fund charges to operate. Trading costs inside the fund and any sales load are separate numbers, so check all three lines when comparing funds.
What expense ratio is considered good?
Broad US index funds sit near 0.03-0.10%, which the table above shows costs four figures over a career instead of five. Anything above 1% needs an argument for why the manager earns it - and the historical argument is weak, which is why the index share of fund assets keeps climbing.
Do I pay the expense ratio if the fund loses money?
Yes - the fee is a percentage of assets, not of profits, so it comes out in up markets and down. A fund that loses 10% still keeps its 1%, which is why the fee decision matters most for money you are certain to stay invested.
