The accounting equation summarizes the essential nature of doubleentry system of accounting. Under which, the debit always equal to credit, and assets always equal to the sum of equities and liabilities. Accounting equation can be simply defined as a relationship between assets, liabilities and owner’s equity in the business.
The accounting equation connotes two equations that are basic and core to accrual accounting and doubleentry accounting system.
The following are two basic rules of accounting equation that distinguishes the accrual system of accounting from cash basis accounting, and singleentry system from the doubleentry system:
It derives its status only from the accrual system of accounting and thereby, it does not apply in a cashbased, singleentry accounting system.
It is pertinent to note that the term basic accounting equation is another name for the ‘Balance Sheet Equation’. The reason balance sheet always balances is because of the following equation:
Assets = Liabilities + Owners Equities
The ingredients of this equation  Assets, Liabilities, and Owner's equities are the three major sections of the Balance sheet. By using the above equation, the bookkeepers and accountants ensure that the "balance" always holds i.e., both sides of the equation are always equal.
The accounting equation represents an extension of the ‘Basic Equation’ to include another fundamental rule that applies to every accounting transaction when a doubleentry system of bookkeeping is used by the businesses.
Debits = Credits
This Accounting Equation summarizes the following:
This equation serves to provide an essential form of builtin error checking mechanism for accountants while preparing the financial statements.
The entire financial accounting depends on the accounting equation which is also known as the ‘Balance Sheet Equation’. The following are the different types of basic accounting equation:
This balance sheet equation tells you that all the assets owned by the business are either sponsored using the owners’ equity or the amount which company should owe others like suppliers or borrowings like Loans
The difference of assets and owner’s investment into business is your liabilities which you owe others in the form of payables to suppliers, banks etc.
This equation reveals the value of assets owned purely by owner equity.
While trying to do this correlation, we can note that incomes or gains will increase owner’s equity and expenses, or losses will reduce it.
Let us understand the accounting equation with the help of an example.
