Comparability Principle

Comparability is one of the key qualities which accounting information must possess. Accounting information is comparable when accounting standards and policies are applied consistently from one period to another and from one region to another. The characteristic of comparability of financial statements is important because it allows us to compare a set of financial statements with those of prior periods and those of other companies.

Examples

  1. We can compare 20X2 financial statements of ExxonMobil with its 20X1 financial statements to know whether performance and position improved or deteriorated.
  2. We can compare the ExxonMobil financial statements with that of BP if both are prepared in accordance with same set of accounting standards, such as IFRS or US GAAP, etc.
  3. When preparing 20X3 financial statements we are required to present with each of the 20X3 figure the corresponding 20X2 figures. This is done to add the characteristic of comparability to the financial statements.

Accounting standards are intended to outline the best accounting treatment so that companies follow them and hence accounting information is understandable, relevant and reliable and comparable. Consistency means that the accounting policies should be changed only when there are valid grounds for such a change.
