The 7-day annualized rate of return is the annualized rate of return for the last 7 days. Every 7 days is different, and there will be fluctuations. It can only be used as a reference standard, which does not mean that you will get this benefit every day after you buy it.

Ten thousand copies of income refers to every ten thousand copies of income, because the net value of the money fund is always 1, so ten thousand copies of income is the income that can be obtained by buying ten thousand yuan. Because the income fluctuates every day, so does the annual income, about 3.5%-4.5%.

Extended data:

The calculation formula of annualized income for seven days is (B-A-C)/A/7*365* 100%.

For example, the value of a money fund before opening on March 7th is 100 yuan (that is, A = 100) and after closing on March 7th is10/yuan (that is, b =10/). Then the seven-day annualized interest rate of this fund is (101-kloc-0/00-0)/100/7 * 365 *100%.

The seven-day annual rate of return of the Fund is rounded to three decimal places.

The regulatory authorities in some countries have strict formulas for calculating the seven-day annualized interest rate: if the value of a monetary fund before the first day of trading is A, the value after the seventh day of trading is B, and the fee for these seven days is C (sometimes, for example, Yu 'ebao, according to the situation of 20 14/3/ 15, C=0).
