For example, I bought a 30,000 yuan wealth management, with an annual interest rate of 4.2% and a purchase period of 30 days.

After 30 days, my income is 30,000 yuan * 4.2%/365 * 30 = 103.5626 yuan.

Extended data:

The wealth management funds in the market are basically based on the earliest mode of issuing wealth management funds to increase wealth. Usually, financial funds have the following characteristics:

1, low threshold. Compared with general bank wealth management products, wealth management funds have obvious low threshold characteristics. The purchase limit of general bank wealth management products is 50 thousand, and it is generally impossible to buy less than 50 thousand. The wealth management fund can be purchased at 1000 yuan. This is a more important factor to attract small ordinary investors.

2. There is no charge. The wealth management fund does not charge subscription and redemption fees. However, a small amount of management fees, custody fees and sales service fees will be charged. According to media statistics, the annual expense rate of monetary fund is about 0.43%, and the average annual expense rate of wealth management fund is about 0.36%. So overall, the cost of buying short-term financial funds is still very low.

3. You can buy it every day. The first phase of bank wealth management products was issued, and the trading time was limited. There are two modes of financial fund trading. One is that Huitianfu can buy on any trading day as long as the fund is open for subscription. The other is the Hua 'an model, which is similar to bank wealth management products and is open for subscription and redemption on a regular basis. At present, the vast majority of wealth management funds in the market are mainly based on the mode of exchange and wealth.

4. Open regularly. Financial management funds have an operating period and cannot be redeemed before the expiration of the operating period. You can't redeem it until it expires. The operation period of the wealth management fund includes 7 days, 14 days, 28 days, 30 days, 60 days, 90 days, etc.

5. Low risk and transparent operation. Financial funds have strict restrictions on the types and duration of their investments. You can't invest in A shares and convertible bonds, but you can only invest in short-term high-security varieties such as central bank bills, short-term financing bills, and agreed deposits within 397 days.

So the risk is very low, equivalent to a money fund. In addition, compared with the bank's wealth management products, the wealth management fund also has an advantage that its operation will be more transparent. Because it is a fund custody, the data of the fund's seven-day annualized rate of return and other yield data will be published every day.

6. The net unit value is always 1 yuan, and the general wealth management fund adopts the amortized cost method similar to the money fund, so its net unit value is always 1 yuan, and the income is calculated daily and carried forward on schedule.

7, automatic rollover, holidays have benefits. Financial funds have a time limit. Compared with the method of redemption of bank wealth management products, if the wealth management funds are not redeemed at maturity, the user's principal and interest will automatically become the share of wealth management funds, which will be rolled over to the next period for investment, so there will be no income blank period similar to that of bank wealth management products. In addition, wealth management funds mainly invest in the money market, and there are also benefits on holidays.
