1, 7-day annualized meaning: the 7-day annualized rate of return of Yu 'ebao is the average income of the last 7 days.

2. Calculation method: The annualized rate of return of Yu 'ebao in recent 7 days is 4. 19%. If you deposit 1 0,000 yuan, the daily income is about 1 yuan 1.2 cents. Here's the payoff. 10000 yuan multiplied by 4. 19%, divided by 365 equals daily income.

3. Because the daily income of all money funds, including Yu 'ebao, is changing, the so-called annualized rate of return on the 7th, 30th and 90s is the annualized rate of return obtained by arithmetic average of the rate of return in the statistical interval.

4. The annualized rate of return is simply your financial capital. In these 7 or 30 days, you have enjoyed the income equivalent to the annual interest rate of X% (X equals the annualized rate of return). The income generated by your investment in Yu 'ebao within 7 days = Yu 'ebao share *X%*7/365.

Extended data:

The annualized rate of return of 1 and 7 days is the average income level of the monetary fund in the last 7 days, which is obtained after annualized. For example, the annualized rate of return of a monetary fund is 2% on the same day, and assuming that the income of the monetary fund in the next year can remain unchanged at the level of the previous seven days, then you can get 2% of the overall income if you hold it for one year.

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

6. For example, before the opening of a monetary fund on March 1 day, the value of each share was 100 yuan (that is, A= 100), and after the closing of the market on March 7, the value of each share was10/yuan (that is, b =/kloc- Then the seven-day annualized interest rate of this fund is (101-kloc-0/00-0)/100/7 * 365 *100%.
