Therefore, the introduction of front-end charges and back-end charges at the same time fully considers the cost of investors. As the name implies, the front-end charge is to pay when buying a fund, and the back-end charge is to pay when buying a fund, and then pay when selling the fund. The back-end rate is graded according to the holding period. The longer the holding time, the lower the rate until it is zero. For example, if an investor pays 10000 yuan to buy "Huaxia Bond Fund" during the issuance period, chooses the back-end charging mode and sells it after holding it for five years, the subscription fees of both the front and back ends of the investor are zero, and the redemption rate of "Huaxia Bond Fund" is also zero, so there is no charge from buying to selling, and the investment cost is greatly reduced.

For small and medium-sized investors with small investment, it is much more affordable to choose the back-end charging mode and hold it for a long time under the same circumstances, especially for bond funds, because they can't enjoy the preferential rates brought by large funds. At the same time, back-end fees are also conducive to investors to establish a healthy investment concept of long-term investment.

As far as fund investment is concerned, if an investor chooses the back-end charging mode, the fees he should pay will always be put into operation as fund assets before redeeming the fund, so as to maximize the value of the funds he invested, and this part of the funds and the income he created will eventually be owned by the investor; If investors choose to hold the fund for a long time at the same time, it will increase the stability of the fund assets, reduce the position adjustment made by the fund manager due to the flow of funds, and avoid unnecessary losses of the fund's net value, and ultimately benefit investors.
