๐ก Did You Know?
๐ How Do Expense Ratios Work?
The expense ratio is deducted from fund assets daily โ you never see a bill. A 0.50% ratio means 0.50% of your investment is paid out annually for management, administration, and marketing.
Formula
Annual Cost = Investment Amount ร Expense Ratio
Example: $100,000 ร 0.50% = $500 per year
Over decades, fees compound against you. Money paid in fees never grows. Our compound interest calculator shows how small differences multiply.

โ Frequently Asked Questions
What is an expense ratio?
An expense ratio is the annual fee charged by mutual funds and ETFs, expressed as a percentage of assets under management. It covers management, administration, marketing (12b-1), and other operational costs. A 0.50% expense ratio means you pay $50 per year for every $10,000 invested.
What is a good expense ratio?
For index funds and ETFs, aim for under 0.20% โ ideally 0.03% to 0.15%. Vanguard S&P 500 (VOO) charges 0.03%. Actively managed funds typically charge 0.50% to 1.50%. Bond funds often have lower ratios (0.05% to 0.50%). Avoid funds over 1% unless they consistently outperform.
How does expense ratio impact returns?
Expense ratios directly reduce your returns. A 1% fee on a $100K investment costs $1,000 annually. Over 30 years with 7% growth, that 1% difference can cost $75,000+ in lost wealth. Fees compound against you โ money paid in fees never grows.
Index fund vs actively managed expense ratios?
Index funds average 0.03% to 0.20% because they passively track an index. Actively managed funds charge 0.50% to 1.50% for research and stock picking. Studies show most active funds underperform index funds after fees. John Bogle founded Vanguard to prove low-cost indexing wins.
What are 12b-1 fees?
12b-1 fees are marketing and distribution fees (up to 1% annually) that some funds charge. They cover broker compensation, advertising, and shareholder services. Many low-cost index funds and ETFs have zero 12b-1 fees. Avoid funds with high 12b-1 fees โ they add no value for buy-and-hold investors.
Total expense ratio vs TER?
Total Expense Ratio (TER) and expense ratio are the same โ the annual cost as a percentage of assets. Some regions use TER (Europe) vs expense ratio (US). Both include management, admin, and 12b-1 fees. Always check the prospectus for the exact figure.
