Theoretically, the fixed investment of the fund has only a lower investment limit and no upper investment limit. But it depends on the regulations of different fund companies or consignment platforms on fund products. For example, on the Alipay platform, the Foundation sets a fixed investment of 10 yuan, and there is no upper limit; ICBC will definitely invest in 200 yuan, and the difference of additional investment must be an integer multiple of 100 yuan, with no upper limit.

After investors set the date, amount and total term of fixed investment, as long as there is enough money in the bank card bound by investors, the fund can operate on its own, which is somewhat similar to regular small deposits. Investors don't have to worry about choosing the right investment opportunity, but they can also get compound interest income for a long time, which is suitable for novice investors or investors who lack time to make a market.

Advantages of fixed investment fund:

1, share the investment cost. Fixed investment of the fund is a regular fixed investment of the fund, which is a simple long-term investment method. If investors want to invest in the fund for a long time, but can't take out a large sum of money at one time to obtain high returns, then they can try to use the method of fixed investment in the fund. Through fixed investment, investors can divide the target investment amount into several equal parts according to the investment years and decide the interval and amount of fixed investment. In this way, the cost of investors is shared, the financial pressure of investors is reduced, and long-term high returns can be obtained.

2. Avoid certain risks. When the fund falls, many people will start to predict the market and intraday trading, which may lead to an increase in investment costs and investment losses. Buy more when the market falls, reduce the cost of holding positions, and avoid the risks brought by investor day trading to some extent.

3. Save time, effort and worry. Investors participate in the fixed investment of the fund, and after signing a contract with the fund, the fund automatically deducts the fixed investment amount of investors in each period within the specified fixed investment period, saving investors' time and energy.

4. The starting point of investment is low. The initial investment amount of the fund's fixed investment is low, and even Alipay platform only needs 10 yuan to start the investment, and there is no investment ceiling. Investors at all levels can participate in the investment.

5. Mandatory savings. After the investor signs the fixed investment agreement, as long as there is enough fixed investment funds in the bank card of the bound account, before the agreement expires, the system will automatically deduct the money to purchase the fund share, which is similar to compulsory savings.
