The 10% discount on the fund rate is because the fund sales organization discounted the rate when selling products. Why should the sales organization discount? This is mainly because lowering the handling fee can sell more shares, and sales organizations can also get sales returns from fund companies.

Fund subscription fee = principal-principal /( 1+ subscription fee). For example, if an investor buys a fund with a price of 1 0,000 yuan, the subscription rate is 0. 15%, and the handling fee is: 1 0,000-0/0,000/(1.15%).
