Because the unit cost of the fund changes from time to time. For example, the unit cost of a fund will change on the trading day, and the unit cost of buying depends on what the unit cost is when buying. For example, when a fund is on the 1th, its net unit value is a 3 yuan. At this time, we bought 3, yuan and held 1, shares. By the 2th, the net unit value of this fund came to 5 yuan. At this time, if you buy another 3, yuan, your share will be 6. The unit net value of the fund does not affect the purchase of the fund. Like stocks, there will be a minimum purchase limit, which is 1 shares. In the fund, there is no such statement, and more needs to look at the specific situation. Generally speaking, 1 yuan can buy, but there are also some funds that are not open to purchase. At this time, it is useless to have funds.

Many people hold funds for a long time, and the unit cost of funds is rising all the way. That is to say, the cost price is different at different time points. When the fund is soaring all the way, the cost price of the fund will become higher relatively, and the share that can be bought with the same money will become less at this time. In the process that the fund has been falling, the unit cost is constantly decreasing, and more shares can be bought at this time. The buying time of the fund is very important. Try to buy it when the fund falls, so that the cost will be reduced and the income will be higher. If you buy at a high point, not only the purchase cost is high, but also you need to take higher risks, which is relatively unworthy.

So the reason why the unit cost in the fund is different from the purchase price is that the unit cost of the fund will change, which may become higher and lower. It depends on the specific situation. The net unit value of high-quality funds will become higher and higher, and the purchase cost will also be higher.
