How much are your fund's fees
actually costing you?
See the true long-run cost of your fund's expense ratio. Compare the potential no-fee growth against your real after-fee balance, and watch the fee-drag zone grow as compounding turns small percentages into large dollar losses.

Field guide
What is an expense ratio and why does it compound against you?
An expense ratio is the annual fee a mutual fund or ETF charges to cover operating costs: portfolio management, administrative overhead, marketing, and compliance. It's expressed as a percentage of assets under management and is deducted continuously from the fund's NAV (net asset value), not charged separately as a cash fee. A fund with a 1% expense ratio effectively reduces its gross return by 1% every year.
That sounds modest. But the math compounds relentlessly. Every dollar lost to fees is a dollar that no longer compounds. Over long time horizons, the fee drag snowballs into a much larger absolute loss than the headline percentage suggests.
The 1% rule: why small differences matter enormously.
Consider a $10,000 investment with $300/month contributions at 8% gross return over 30 years:
- 0.03% expense ratio (index ETF): ~$430,000 final balance. Fees cost roughly $3,000 over 30 years.
- 1.00% expense ratio (actively managed): ~$370,000 final balance. Fees cost roughly $63,000 over 30 years.
- 2.00% expense ratio (high-fee fund): ~$315,000 final balance. Fees cost roughly $118,000 over 30 years.
The 1% fund costs 21× more than the 0.03% fund in absolute dollar terms; yet the expense ratio is only 33× higher. That amplification is the direct result of compounding: you lose not just the fee itself but all the growth that fee would have generated.
Index funds vs. actively managed funds.
The debate between passive and active management is one of the most empirically settled in finance:
- Passive index funds track a market index (S&P 500, total market, bond index) mechanically. No research team, no stock picking. Expense ratios run 0.03% to 0.20%. They cannot beat the market by definition, but they capture nearly all of it.
- Actively managed funds employ portfolio managers who attempt to outperform a benchmark. Expense ratios typically run 0.50% to 1.50%, sometimes higher. The fund also incurs trading costs (bid-ask spreads, commissions) that erode returns further but don't appear in the expense ratio.
The SPIVA Scorecard (S&P Dow Jones Indices) has tracked fund performance for over 20 years. Its consistent finding: over any 15-year period, roughly 88–92% of actively managed US equity funds underperform their benchmark index after fees. The expense ratio is not just a cost. It's a headwind that most active managers fail to overcome.
This doesn't mean active management never wins; some funds and managers do consistently outperform. But identifying them in advance is extremely difficult, and their higher fees mean you need meaningfully better gross returns just to break even against a cheap index fund.
What is a “good” expense ratio?
The landscape has shifted dramatically over the past two decades. Vanguard, Fidelity, and BlackRock (iShares) have driven index fund fees toward near-zero:
| Fund type | Typical range | Examples |
|---|---|---|
| Broad index ETF | 0.03% – 0.07% | VOO, VTI, ITOT, FZROX |
| Sector / thematic ETF | 0.10% – 0.50% | Clean energy, tech, REITs |
| Low-cost active fund | 0.20% – 0.75% | Some Fidelity / DFA funds |
| Typical actively managed | 0.75% – 1.50% | Most mutual fund companies |
| High-fee / load funds | 1.50% – 3.00% | Some annuity subaccounts, alternatives |
As a general benchmark: anything above 0.50% for a core portfolio position warrants scrutiny. Above 1.00%, you need strong evidence of consistently superior after-fee returns to justify the cost.
How the calculator models expense ratio drag.
The expense ratio is modeled as a continuous annual drag on portfolio returns: net return = gross return − expense ratio. Both scenarios compound monthly using the geometric monthly rate derived from the annual return. This reflects how fund NAVs actually work; the fee is embedded in the daily price movement, not charged as a separate cash deduction at year-end.
The fee drag displayed is the year-by-year (and cumulative) difference between what you'd have in a zero-cost fund versus your actual after-fee balance. Because the difference compounds, the red zone on the chart grows non-linearly; the fee drag in year 25 is much larger than 25× the fee drag in year 1.
Disclaimer
This calculator assumes constant annual returns. Real returns are variable, and sequence of returns risk means actual outcomes differ from projections. The model does not include taxes on dividends or capital gains distributions, which also vary by fund type and account. Consult a financial adviser before making investment decisions.
