In finance, an accrual (accumulation) of something is the adding together of interest or different investments over a period of time. Accruals in accounting For example, a company delivers a product to a customer who will pay for it 30 days later in the next fiscal year, which starts a week after the delivery. The company recognizes the proceeds as a revenue in its current income statement still for the fiscal year of the delivery, even though it will not get paid until the following accounting period. The proceeds are also an accrued income (asset) on the balance sheet for the delivery fiscal year, but not for the next fiscal year when cash is received. Similarly, the salesperson who sold the product earned a commission at the moment of sale (or delivery). The company will recognize the commission as an expense in its current income statement, even though the salesperson will actually get paid at the end of the following week in the next accounting period. The commission is also an accrued liability on the balance sheet for the delivery period, but not for the next period when the commission (cash) is paid out to the salesperson. The term accrual is also often used as an abbreviation for the terms accrued expense and accrued revenue that share the common name word, but they have the opposite economic/accounting characteristics.
