Which term refers to the amount of money in a business at the end of a month?

The term that refers to the amount of money in a business at the end of a month is known as the closing balance. This figure represents the total cash available after all transactions—income and expenditures—have been accounted for during that month. It is a snapshot of the business's liquidity position at the end of the accounting period.

In contrast, the opening balance refers to the amount of money a business has at the beginning of a month or accounting period, which does not give the current status but instead provides a starting point for tracking cash flow. Cumulative cash flow indicates the total cash flow over a certain period, but it does not specifically refer to the ending position at a particular point in time. Net cash flow is the difference between cash inflows and outflows over a specific period but again does not indicate the amount remaining at the end of that period. Therefore, closing balance is the most accurate term to describe the final cash amount in a business at the end of a month.
