The rate of return of open-end funds can be reflected in two parts, one is the growth of the fund's net value, and the other is the dividend of the fund. An approximate formula for calculating the annual return of funds is: annual return of funds = (net fund share at the end of the year-net fund share at the beginning of the year)/(net fund share at the beginning of the year-dividend at the beginning of the year) * 100% Generally speaking, the higher the return on investment, the higher the efficiency of fund assets operation, the better the fund performance and the higher the income of fund investors. Calculate your fund income: current profit and loss = current market value+cash dividend.

Current rate of return = (current profit and loss/investment amount) × 100%

Total yield = (total current profit and loss/total residual principal) × 100%
