The annual operating cost of a fund expressed as a percentage of average assets.
How it works
A fund’s expense ratio expresses recurring operating expenses as a percentage of average net assets. These costs are generally deducted inside the fund and reduce investor returns.
Example
A 0.25% expense ratio represents about 25 in annual fund expenses for each 10,000 invested, though the daily effect varies with asset value.
Limitations
It excludes some trading costs, spreads, taxes, advice fees, and account charges. Low cost alone does not make a fund suitable.
