Every business uses resources to generate revenue and maintain its operations. Some of those resources are recognized as expenses immediately, while others are initially recorded as assets and become expenses only when they are consumed, sold or depreciated.
An expense does not always involve an immediate cash payment. A company may recognize an electricity expense before paying the supplier, pay insurance in advance and recognize the expense over several months, or record depreciation without making a cash payment during the period.
Understanding these differences helps finance teams calculate profit correctly, prepare reliable financial statements, control spending and distinguish operational costs from asset purchases.
This guide explains what an expense means in accounting, how expenses differ from costs and expenditures, the main ways businesses classify them and the journal entries used to record common examples.
An expense is a decrease in economic benefits recognized during an accounting period that reduces the business’s profit and equity, other than a distribution to owners.

An expense does not have to involve an immediate cash payment.

For example, suppose a business uses SAR 3,000 of electricity during June but pays the supplier in July. Under accrual accounting, it records the expense in June:
Debit: Utilities Expense — SAR 3,000
Credit: Accrued Expenses or Accounts Payable — SAR 3,000
When the amount is paid in July, the business removes the liability:
Debit: Accrued Expenses or Accounts Payable — SAR 3,000
Credit: Cash — SAR 3,000
The July payment does not create a second expense because the expense was already recognized in June.
