As long as you can hold it for more than 5 years, the back-end charge is free.
In the case of direct sales, except for a few fund companies that charge 0.6%, the others charge 0.8%- 1.2%. The previous charging standard was 0.6%, which was recently increased (so I won't buy an open-end fund now).
The back-end fee is the same as consignment.
Suggestion: If you want to buy bond funds and money funds, you can go to the direct sales center to buy them. If checked, the handling fee is high and the arrival time is slow. If you want to buy stock funds, I suggest that you can use your stock account to buy closed-end funds in the secondary market. Closed-end funds not only trade at a discount, but also receive accounts quickly and the handling fee is not high, and only charge brokerage commissions.
