How do you calculate Quarterly Average Assets Under Management of mutual fund?

To calculate the Quarterly Average Assets Under Management (AUM) of a mutual fund, you first need to determine the AUM at the end of each month within the quarter. Then, sum these monthly AUM figures and divide the total by three, as there are three months in a quarter. This provides the average AUM for that quarter. Alternatively, you can calculate it using daily AUM figures by summing all daily AUM and dividing by the number of days in the quarter.
