Expense Ratio Calculator
The Expense Ratio Calculator shows how fund management fees eat into your investment returns over time. Enter a fund's expense ratio and your investment amount to see the annual cost, 10-year impact, and comparison against index fund alternatives.
What is an Expense Ratio?
An expense ratio is the annual fee charged by a mutual fund or ETF to cover operating costs, expressed as a percentage of assets under management. A 0.50% expense ratio means you pay $50 per year for every $10,000 invested. This fee is deducted automatically from fund returns.
Expense ratios range from 0.03% for passive index funds (like Vanguard S&P 500) to over 2% for actively managed specialty funds. Over decades, even small differences in expense ratios compound into massive cost differences — a 1% higher fee can reduce your portfolio by 25% over 30 years.

Domande Frequenti
What is a good expense ratio? ▼
For index funds, 0.03%-0.20% is excellent. For actively managed funds, under 0.75% is good. Above 1.5% is expensive and hard to justify unless the fund consistently outperforms its benchmark after fees.
How are expense ratios charged? ▼
Expense ratios are deducted daily from the fund's net asset value (NAV). You don't receive a bill — the fee is automatically reflected in lower fund returns. A 0.50% annual ER means about 0.00137% is deducted each day.
Do ETFs have lower expense ratios than mutual funds? ▼
Generally yes. The average ETF expense ratio is about 0.16%, while the average mutual fund charges about 0.47%. Passive index ETFs can be as low as 0.03%.
Should I switch funds to save on expense ratio? ▼
Consider switching if the fee savings are significant (0.5%+ difference), the fund isn't outperforming, and there are no exit fees or tax consequences. Even 0.3% savings on a $200K portfolio saves $600/year.
Do expense ratios include trading costs? ▼
No. Expense ratios cover management fees, administration, and marketing costs (12b-1 fees). Trading costs (commissions, bid-ask spreads) are separate and reflected in fund returns but not the stated expense ratio.
