The calculation method is different:

External deduction formula:

Net subscription amount = subscription amount /(1+ subscription rate)

Subscription fee = subscription amount-net subscription amount

Subscription share = (subscription amount-subscription fee)/fund share face value

Internal deduction formula:

Subscription rate

subscription share = (subscription amount-subscription fee)/face value of fund share

For example, suppose that a fund is to be subscribed for 1, yuan, the subscription rate is 1.5%, and the net value of the fund is 1 yuan.

calculated by internal deduction method: net subscription amount =1×(1-1.5%)=985 share =985/1=985

calculated by external deduction method: net subscription amount =1/(1+1.5%)=9852.22 share = 9852.22 share. The calculation method is as follows:

profit and loss of the day = available share of the day * ten thousand profits of the day/1,

cumulative profit and loss = market value of positions+redemption amount+cash dividend amount+transfer-out fund amount-subscription amount-fixed investment amount-transfer-in fund amount

2. If it is a non-monetary fund, The calculation method is as follows:

profit and loss of the day = available share of the day * net fund return rate of the day

cumulative profit and loss = market value of positions+redemption amount+cash dividend amount+transfer-out fund amount-subscription amount-fixed investment amount-transfer-in fund amount
