Cumulative return rate of funds = (total amount of funds sold-total amount of funds bought)/total amount of funds bought × 100%, and the cumulative return rate of funds will be directly displayed in the investor's account without manual calculation by investors.

For example, if an investor buys a fund of 6,543.8+10,000 yuan, and sells it after holding it for a period of time, the selling amount is 654.38+ 065.438+000,000 yuan, then the cumulative rate of return of the fund can be calculated as: (654.38+065.438+00000 yuan-654.38+000000 yuan).
