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.
Expense ratios are stated in terms of the annual percentage of assets that will be charged. Here are a few examples: A fund that has an expense ratio of 1.10 charges 1.10% a year of the total assets you have in the fund. A fund that has an expense ratio of .20 charges .20% or 1/5th of 1% of the amount you have invested.
