Assuming that the financing principal is RMB 654.38+10,000, the reference annualized net investment return rate of this product is 4%, and the actual financing period is 62 days, then the investor's income =100000× 4 %× 62/360 = 918.52 yuan. 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.

Annualized rate of return The annual rate of return converted from the net income per 10,000 fund shares of the Monetary Fund in the past seven days. There are two ways to carry forward money market funds: 1. "Daily dividends are carried forward on a monthly basis", which is equivalent to daily simple interest and monthly compound interest; 2. "Daily dividends are carried forward daily", which is equivalent to daily compound interest.

I. Annualized rate of return The annual rate of return converted from net income per 10,000 fund shares of the Monetary Fund in the past seven days. There are two ways to carry forward money market funds:

Calculation method of annualized rate of return:

Investors put the principal C into the market, and its market value becomes V after time t, so in this investment:

1, and the return is: p = v-c.

2. The rate of return is: K=P/C=(V-C)/C=V/C- 1.

3. The annualized rate of return is:

(1) y = (1+k) n-1= (1+k) (d/t)-1or

(2)y=(v/c)^n- 1=(v/c)^(d/t)- 1

Where N=D/T represents the number of repeated investments by investors within one year. D stands for the effective investment time of one year, with bank deposits, bills and bonds being D=360 days, stocks and futures being 250 days, and real estate and industry being D=365 days.

4. In the case of continuous multi-period investment, y = (1+k) n-1= (1+k) (d/t)-1.

Where: K=∏(Ki+ 1)- 1, T=∑Ti.

Second, the seven-day annualized rate of return.

The annualized rate of return of 1 and 7 days is the annual rate of return converted from the net income per 10,000 fund shares of the Monetary Fund in the past seven days.

The daily income of money funds will change constantly with the operation of fund managers and the fluctuation of money market interest rates. In fact, it is unlikely that the fund's income will remain unchanged for one year.

2. The regulatory authorities in some countries have strict formulas for calculating the annualized interest rate for seven days: if the value of a money fund is A before the first trading day and B after the seventh trading day, then the fee for these seven days is C (sometimes, for example, Yu 'ebao, according to the situation of 2014/315, C=0).

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