Generally, you can see the benefits in two days after buying a money fund. The monetary fund is generally t+ 1, and the share is confirmed. If it is Friday, you have to wait until Monday. Suppose the investor bought the fund before Monday 15:00, and calculated the income after confirming the share on Tuesday, and you can see it on Wednesday.
It is also worth noting that the net value of a fund is only one copy per day, which is generally updated around 20 o'clock that day (delay is not excluded). If it is a consignment fund, some platforms will be updated the next day.
