Transaction rate, front end, back end. Stock-based trading rate is zero. Transaction costs include subscription rate, subscription rate, redemption rate and conversion rate. The management fee has been deducted in advance and investors may not consider it. The subscription rate of the far front-end is usually 1.0%, which is lower than that of the general front-end 1.5% (confirmed subscription cost = confirmed subscription rate * investment), so the front-end interest rate is to pay the subscription money in advance. If it can be confirmed that it has been held for more than three years, you can choose to hold the back-end subscription rate for more than three years, and the back-end subscription rate can be reduced to zero. The redemption rate of 1 year is usually in the range of 0.5% (redemption fee = redemption rate of redemption fund * market value). Funds may be different, please consult the announcement of your own funds for details.
