Accounting Period Concept

Even though it is assumed that business will continue to exit for a long time, it is necessary to keep accounts in such a manner that the results are known at frequent intervals. Generally business concern adopt twelve months period for measuring the income of the concern.

This time interval is called 'Accounting Period'. At the end of each accounting period an Income and Expenditure Account and Balance Sheet are prepared. The Income and Expenditure Account disclose the income or loss sustained by the business during the accounting period. Similarly balance sheet reveals the financial position of the business on the last day of accounting period.

Truly speaking, the measurement of income or loss of a business entity is relatively simple on a whole life basis. A complete and accurate picture of the degree of success achieved by a business unit cannot be obtained until it is liquidated, converts its assets into cash and pays off its debts. On liquidation, it is possible to determine with finality its net income. But the owners, the investors and overall the Government, all are impatient and don not want, until the dissolution of the concern, to know what has been the results of the business activities. All these persons are interested in regular reports and accounts at proper intervals to know "how things are going?" This means that the final accounts must be prepared on a periodic basis rather than waiting till the business is terminated.

Dual Aspect Concept or Accounting Equivalence Concept

This is the basic concept of accounting. According to this concept, every financial transaction involves a two-folded aspect, (a)yielding of a benefit and (b) the giving of that benefit. For example, if a business has acquired an asset, it must have given up some other asset such as cash or the obligation to pay for it in the future. Thus a giver necessarily implies a receiver and a receiver necessarily implies a giver. There must be a double entry to have a complete record of each business transaction, an entry being made in the receiving account and an entry of the same amount in the giving account. The receiving account is termed as debtor and the giving account is called creditor. Thus every debit must have a corresponding credit and vice versa and upon this dual aspect has been raised the whole superstructure of Double Entry System of Accounting. 

The Accounting Equation, (i.e., Assets=Equities(or Liabilities+Capital) is based on dual aspect concept.

The term 'Assets' denotes the resources owned by the business while the term 'Equities' denotes the claims of various claimants including the proprietors of the business against the assets.

Cost Concept

A concept of accounting, closely related to the going concern concept, is that an asset is recorded in the books at the price paid to acquire it and that this cost is the basis for all subsequent accounting for the asset. This concept does not mean that the asset will always shown at cost but it means that cost becomes basis for all future accounting for the asset. Asset is recorded at cost at the time of its purchase but is systematically reduced in its value by charging depreciation. The market value of an asset may change with the passage of time, but for accounting purpose it continues to be shown in the books at its book value, i.e., the cost at which it was purchased minus depreciation provided up to date.

Going Concern Concept or Continue of activity concept

It is assumed that a business unit has a reasonable expectation of continuing business at a profit for an indefinite period of time. A business unit is deemed to be a going concern and not a gone concern. It will continue to operate in the future. Transactions are recorded in the books keeping in view the going concern aspect of the business unit. 

Money Measurement Concept

Money Measurement Concept

Money is the only practical unit of measurement that can be employed to achieve homogeneity of financial data, so accounting records only those transactions which can be expressed in terms of money though quantitative records are also kept. 

Business Entity Concept

Business Entity Concept

This concept implies that a business unit is separate and distinct from the person who supply capital to it. Irrespective of the form of organisation, a business unit has got its own individuality as distinguished from the persons who own or control it.
