Dual Aspect Concept: Definition

The dual aspect concept of accounting relates to the idea of double entry bookkeeping. Every transaction affects the business in at least two aspects. These two aspects are equal and opposite in nature. It is also known as the accounting equivalence concept.

Dual Aspect Concept: Explanation

To ensure a comprehensive and complete record, it is necessary to make two entries to record each transaction. This concept is based on the assumption that a business never truly owns anything.

Anything that a business has (namely, assets) is owed either to outsiders (i.e., liabilities) or to the owner who is a separate entity (i.e., capital). Hence, when a business gets anything, it must record both facts: an increase in assets and an increase in liability or capital.

Similarly, whenever anything leaves the business, there is a reduction in assets and a corresponding reduction in either liability or capital. This fact applies to all the transactions that a business may enter into at any stage of its existence.

There are two types of claims against the assets of the business: one of the owners and another of the creditors. So, we can say that the total assets of a business are equal to its liabilities.

Liabilities to owners are known as capital and liabilities to others are called liabilities. We can express this relationship between assets and liabilities in the form of the following equation:

Assets = Liabilities + Capital

This concept is based on the fact that if there is something given, someone else receives it. It can also be said that every time a transaction takes place, there is always a two-sided effect. A transaction may affect either both sides or only one side of the accounting equation.

Thus, according to this concept, every transaction has two effects for the same amount: one is a debit and the other is a credit. This is explained with the help of the following example.

Example

If Mr. A starts a business with cash amounting to $100,000, it will have the following effects on the accounting equation:

Assets                                   = Liabilities                               + Owner’s Equity
Cash     +                              = Capital
1,00,000                               = 10,000

If Mr. A purchases goods as credit from Mr. B amounting to $10,000, then the latest position of the accounting equation will be as follows:

Assets                                   = Liabilities                               + Owner’s Equity
Cash  +  Purchases              = Creditors                               + Capital
100,000                               = 10,000
100,000  +  10,000             = 10,000                                  + 100,000

As this example shows, every new transaction will affect the accounting equation. It is important to remember that both sides of this equation will always remain equal.

Further Explanation

In defining the other accounting concepts, it was mentioned that accounting is essentially concerned with the business entity itself rather than its owners, managers, or employees.

Clearly, then, the assets owned by a business enterprise are the property (or, in legal terminology, the equity) of the persons who provided the funds for the acquisition of such assets.

Example 2

For example, if Mr. A uses $500,000 in cash as the start-up capital for a business called Modern Traders, the assets owned by the company at that stage would be a cash balance of $500,000.

Corresponding to this amount would be the equity (i.e., an amount that can be claimed by Mr. A). This relationship is expressed as follows:

Assets = Equities (Claims)

In accounting terms, this transaction is represented as follows:
Accounting for Start-up Capital
Suppose that after some time, goods worth $400,000 are purchased with this start-up capital. The position would change as follows:
Accounting for Purchase
Subsequently, if the business enterprise borrows $300,000 from a bank to finance its purchases, the new position would be:
Accounting for Borrowed Funds
The equity or claim of an outsider is technically called a liability. So, we might rewrite our equation in the following way:

Assets = Equities = Owners’ equity + Outsiders’ equity = Owners’ equity + liabilities

Thus, the accounting equation that finally emerges is:

Assets = Owners’ equity + Liabilities

This accounting equation can be used to record any business transaction, however complex. To pursue our accounting examples, assume that goods worth an additional sum of $350,000 are purchased in cash. The situation would now be:
Accounting for Additional Purchase
Thereafter, goods worth $700,000 are sold for $900,000 cash. It is easy to make the necessary adjustments in the value of the goods, which will now come down from $750,000 to $50,000.

However, cash or other assets have now increased by $900,000, resulting in an extra amount of $200,000 on the equities side as well. To whom does this extra amount of $200,000 accrue as property?

Clearly, the banker cannot claim more than the original sum of the money lent to the enterprise (i.e., $300,000). This is simply because the company’s transactions have been profitable. So, the outsiders’ equity or liability will remain constant at $300,000.

Inevitably, we come to the conclusion that this sum belongs to the owners and should be recorded in the owners’ equity. The resulting situation will now be:
Accounting for Owners' Equity
A few days after this transaction, the broker claims $50,000 as their commission for bringing the business to the enterprise, and the sum is duly paid.

Clearly, the banker will not accept anything less than $300,000 (i.e., the original amount lent) because expenditure has been incurred by the enterprise. The amount of outsiders’ equity or liability must, therefore, be maintained at its original figure of $300,000.

The decrease in assets due to an expense incurred to earn profit would, therefore, be viewed as a reduction in the owners’ equity. The final picture is shown as follows:
Accounting for Reduction in Assets
This concept is technically stated as follows: “for every debit, there is a credit.”

Notice that the comparison of owners’ equity at the beginning of the accounting period ($500,000) and at the end of it ($650,000) enables us to determine the profit for the period (i.e., $150,000).

As this represents the economist’s concept of profit, the accounting equation provides us with a method of profit measurement. Since the profit has not been withdrawn by the owner, we can prepare the balance sheet at the end of the accounting period as follows:
