2.7: Debit and Credit Effects for Revenues and Expenses

In accounting, debit and credit are used to record transactions systematically. Every transaction affects at least two accounts, and the double-entry system ensures that the accounting equation stays balanced. Regarding revenues and expenses, the effects of debits and credits follow a specific rule based on how these accounts influence a company’s equity.

Revenues increase the owner's equity. So, the revenue account is credited when a business earns income through sales, services, or interest. For example, if a company earns ₹10,000 in sales, it will credit the sales revenue account, which increases the overall income. On the other side of the transaction, cash or accounts receivable is debited, reflecting the inflow of money or the expectation of future cash.

Expenses, on the other hand, reduce the owner’s equity. That’s why expense accounts are debited when recorded. For example, if a business pays ₹5,000 in rent, the rent expense account is debited, and cash is credited. This shows that an expense has been incurred and resources have been used. Recognizing the effects of debit and credit on revenues and expenditures helps maintain accurate records and supports correct financial reporting.

Revenue is the income a business earns from selling goods or services. 
On the other hand, an expense is the cost a business incurs to earn revenue, such as salaries and utilities.
Consider Sarah, who owns a bakery. 
She sells cakes worth five thousand dollars in a month, generating revenue. 
This transaction is recorded by crediting the Sales Revenue account and debiting the Cash account. It shows that Sarah has earned income.
Revenues have a normal credit balance because they increase Sarah’s net income, raising her equity. 
In the same month, Sarah pays eight hundred dollars for electricity and records it as an expense. 
The Utility Expense account is debited, and the Cash account is credited. This reflects the cost of operating the bakery. 
Expenses have a normal debit balance because they decrease Sarah’s equity. 
By understanding the effect of debits and credits on revenues and expenses, Sarah can maintain accurate financial records.
