Definition of Total Expense Ratio Total expense ratio (TER) is the ratio between total fund costs and total fund assets. It provides information regarding total costs involved annually for investment funds.
In contrast to the gross expense ratio, the net expense ratio does reflect fee waivers in effect during the time period, and does not include interest and dividends on borrowed securities. The expense ratio does not reflect the fundâs brokerage costs or any investor sales charges.
