The total sum of each transaction is displayed for the searched period. In the case of an unconditional full inquiry or an asset or liability inquiry, the accumulated amount from the start of the household account book to the searched period is displayed. It is a concept similar to the balance of a deposit and withdrawal passbook. On the other hand, if you are looking at the cost or revenue side, it displays the sum of the start and end dates.
The total within the period may not be displayed under certain conditions. This includes searching for items for which no item is specified.
