What Is an Expense Ratio? Definition and Example

An expense ratio is the yearly fee a fund charges, shown as a percentage of the money invested. A 0.10% ratio costs about 1 per 1,000 invested each year.
What it means
The fee is taken from the fund's assets, so you do not see a bill, but it reduces your return every year. Over decades, small differences add up. Compare expense ratios for similar funds, together with tracking quality and other costs such as brokerage and currency conversion.
Example
On 10,000 invested, a 0.05% ratio costs about 5 a year, while a 1% ratio costs about 100 a year.
Why it matters
Costs are one of the few things you can control as an investor.
