The basic accounting formula forms the logical basis for double entry accounting. The formula is:
Assets = Liabilities + Shareholders' Equity
The three components of the basic accounting formula are:
In essence, a business uses liabilities and shareholders' equity to obtain sufficient funding for the assets its needs to operate.
The basic accounting formula must balance at all times. If not, a journal entry was entered incorrectly, and must be fixed before financial statements can be issued. This balancing requirement is most easily seen in the balance sheet (also known as the statement of financial position), where the total of all assets must equal the combination of all liabilities and all shareholders' equity.
The basic accounting formula is one of the fundamental underpinnings of accounting, since it forms the basis for the recordation of all accounting transactions. In essence, if both sides of the basic accounting formula do not match at all times, there is an error in the accounting system that must be corrected.
The following table shows how a number of typical accounting transactions are recorded within the framework of the accounting equation:
|Transaction Type||Assets||Liabilities + Equity|
|Buy fixed assets on credit||Fixed assets increase||Accounts payable (liability) increases|
|Buy inventory on credit||Inventory increases||Accounts payable (liability) increases|
|Pay dividends||Cash decreases||Retained earnings (equity) decreases|
|Pay rent||Cash decreases||Income (equity) decreases|
|Pay supplier invoices||Cash decreases||Accounts payable (liability) decreases|
|Sell goods on credit (part 1)||Inventory decreases||Income (equity) decreases|
|Sell goods on credit (part 2)||Accounts receivable increases||Income (equity) increases|
|Sell services on credit||Accounts receivable increases||Income (equity) increases|
|Sell stock||Cash increases||Equity increases|
