Expense Ratio

An expense ratio represents the total annual cost of owning a mutual fund or ETF, expressed as a percentage of your investment. If a fund has an expense ratio of 0.50%, you pay $5 per year for every $1,000 invested. This fee is deducted automatically from the fund's returns and is not billed separately.

Expense ratios vary widely by fund type. Passively managed index funds often charge between 0.03% and 0.20%, while actively managed funds typically charge 0.50% to 1.50% or more. Some specialty or alternative investment funds charge over 2%. The difference may seem small, but over a 30-year investment horizon, a 1% difference in expense ratio can reduce your final portfolio value by more than 25%.

Research consistently shows that lower-cost funds tend to outperform higher-cost funds over the long term, primarily because active managers rarely beat their benchmark index after fees. This finding has driven massive investor flows from actively managed mutual funds to low-cost index funds and ETFs. When selecting investments, expense ratio should be one of the first factors evaluated.
