The calculation method of the fund's custody fee and management fee is as follows: the fund's management fee and custody fee are accrued daily and paid monthly according to a certain proportion of the fund's net asset value of the previous day. If the daily fund management fee payable = (the net asset value of the previous day × the annual management fee)/the actual number of days in the current year, it will be paid from the fund assets, and it is not necessary to charge investors separately. Investors buy 10000 fund, the net value of the fund is 1.0, the management fee is 1.5% (usually the annual management fee), and the annual custody fee is 0. 1%. Then the fund management fee accrued on that day =1000×1.0×1.5 %×1/365 = 0.411yuan, and the custody fee =1yuan. Generally speaking, the fund management fee rate is usually inversely proportional to the fund size and directly proportional to the risk, that is, the larger the fund size, the lower the fund management fee rate; The higher the risk degree of the fund, the higher the fund management fee rate. At the same time, the fund management fee rate is also affected by the fund type. In China, the fund management fee is accrued according to the ratio of 1.5%. The extraction ratio of bond fund management fee is less than1%; The extraction ratio of monetary fund management fee shall not be higher than 0.33%.
