What is the interest due on a note payable in one fiscal period but not paid until the next fiscal period called?

The interest due on a note payable in one fiscal period but not paid until the next fiscal period is called "accrued interest." This interest is recognized as a liability on the balance sheet at the end of the fiscal period in which it is incurred, even though the payment occurs later. It reflects the obligation to pay interest that has accumulated but remains unpaid.
