Definition of 'Accrued Expense'
An accounting expense recognized in the books before it is paid for. It is a liability, and is usually current. These expenses are typically periodic and documented on a company's balance sheet due to the high probability that they will be collected.
Investopedia explains 'Accrued Expense'
Accrued expenses are the opposite of prepaid expenses. Firms will typically incur periodic expenses such as wages, interest and taxes. Even though they are to be paid at some future date, they are indicated on the firm's balance sheet from when the firm can reasonably expect their payment, until the time they are paid.
An example would be accruing interest that is building up on a bank loan.
