Fund selling income is calculated according to the root fund share. The calculation formula of fund redemption amount is: redemption amount = (fund share * net value of fund share on T day)-redemption fee. Fund share refers to the number of funds held by investors, and the fund share at the time of redemption can be the same as or different from that at the time of purchase. When redeeming, the system will generally automatically calculate the fund shares, and investors only need to select the corresponding redemption shares, without having to calculate them themselves.

Net value of fund share on t day. T-day refers to the trading day of the fund, excluding legal holidays and weekends. The calculation period is based on the closing time of the story, that is, T-day before 15:00 and T+ 1 after 15:00. The rate of fund redemption fee is generally set according to the number of days held by the fund. Redemption fee = (fund share * net value of fund share on T day) * redemption rate.

The selling price of the fund is the net value of the fund unit on the day when the fund is sold (T day). For example, the net unit value of the fund on T day is 1, which means that the selling price of the fund is 1 yuan/share. T day refers to the fund trading day, excluding weekends and legal holidays. And the calculation time of the trading day is bounded by the closing time of the stock market 15:00. If it exceeds 15:00, the next trading day will be counted as T day. For example, if an investor submits a redemption application before March 6 15:00, then March 6 (Friday) is T day, and the selling price of the fund is calculated according to the net value of the fund unit on March 6. If an investor submits a redemption application after March 6th (Friday) 15:00, the redemption of the fund shall be calculated according to the net value of the fund on the next trading day. Since March 7th and 8th are weekends, not counting trading days, the next trading day is March 9th (Monday).

The net fund value is not updated in real time. Open-end funds update their net value once a day after the stock market closes (15:00). The fund must be sold before 15:00 on the same day, and the net value of the day must be updated after 15:00, so investors actually don't know their selling price when selling the fund. The unit net value seen by investors on the day of selling is the fund net value of the previous trading day.
