1, the general formula for calculating the fund share. Fund share is the net value of the fund at the time of confirmation after deducting the formalities fee for investors to purchase the fund, that is, fund share = (purchase fund-formalities fee)/confirmation net value. For example, if an investor buys a fund with 654.38+10,000 yuan, the redemption rate is 1.5%, and the confirmed net value of the fund is 1 yuan, then the fund share = (10000-100000×1.5).

2. Calculation of subscription fund shares. When purchasing fund shares, you need to calculate the net subscription amount first, that is, divide the subscription fund amount by (1+ subscription fund rate), then calculate the subscription fund fee, that is, subtract the net subscription fund amount from the subscription fund amount, and finally calculate the subscription fund share, that is, divide the net subscription fund amount by the net fund share value on T day.

3. Calculation of redemption fund shares. When redeeming fund shares, it is necessary to first calculate the total redemption amount, that is, the redemption share multiplied by the net value of fund shares on T day, then calculate the redemption fee, that is, the total redemption amount multiplied by the redemption rate, and finally calculate the net redemption amount, that is, the total redemption amount minus the redemption fee.
