"7-day annualized rate of return" is the average income level of the money fund in the last 7 days, which is obtained by calculating the geometric average of the yield of the product in the last 7 days. The formula is as follows: (∑Ri/ 10000 copies) 365/7× 100%.

The calculation method of annualized rate of return is to convert the current rate of return (daily rate of return, weekly rate of return, monthly rate of return) into annual rate of return, which is a theoretical rate of return, not an actual rate of return. For example, the daily rate of return is one in ten thousand, and the annualized rate of return is 3.65% (an average of 365 days a year). Because annualized rate of return is variable, annualized rate of return is not necessarily the same as annualized rate of return.
