Accounting Equation With Revenue and Expense

1. Basic accounting equations can be extended by incorporating the equity component of the owner, ie capital, revenue, and expenses as follows:

Asset = Liability + Owner’s Equity

Asset = Liability + [Capital + Net Profit]

Asset = Liability + [Capital + (Revenue-Expense)

Which,

Asset = Liability + Capital + Revenue – Expense

2. When a transaction involves revenue and expense, profit or loss will be available:
Revenue > Expense → Net Profit → Owner’s Equity increase

Revenue < Expense → Net Loss → Owner’s Equity decrease

3. From the accounting equation, the revenue derived from the transactions will lead to an increase in assets, or the reduction of liabilities. Such instances include:
(a) When merchandise is sold in cash, assets are increased in cash.
(b) If the merchandise is sold on a credit basis, assets are increased in the form of debtors.
(c) If the proceeds are used to pay the creditor, the liability will be reduced in the form of creditors.
4. Expenses result in asset diminution, or in other words, an increase in liabilities. When an item is paid in cash, liability is incurred in cash, or rather, the assets in cash are reduced. If an expense remains unpaid, the liability increases in the form of accrued expenses.
