A Vertical Analysis of Financial Statements of a company, in which the amounts of individual items of the Balance Sheet or Statement of Profit & Loss are expressed in relation to a common base, is known as a Common Size Financial Statement. In this method, the figures are converted into percentages by taking Revenue from Operations or Net Sales as the base in the Statement of Profit & Loss, and Total Assets or Total Equity and Liabilities as the base in the Balance Sheet. These percentages are then compared with corresponding percentages of other periods or other firms to draw meaningful conclusions regarding financial performance and position. A Common Size Statement is useful for both intra-firm and inter-firm comparisons of the Balance Sheet as well as the Income Statement.
Common-size Statements are accounting statements expressed in percentage of some base rather than rupees.~ Kohler
