The credit card report shows the total amount spent on each credit card by month. In other words, it shows the estimated billing amount. On the other hand, credit cards in asset liabilities include the amount of past use that has not yet been settled, the amount that is currently used and settled in the next month, and, if there is an installment, a future amount. In addition, some prepaid amounts may be reflected. Asset liabilities cover all of these cases, so of course there may be a difference from the amount charged this month on your credit card report.
