# What is Common Size Statement in Management Accounting

Learn about common size statement in management accounting and how it helps in financial analysis and decision-making. Discover the importance, components, examples, case studies, and statistics of common size statements.

## Introduction to Common Size Statement

Common size statements are financial statements where each line item is shown as a percentage of a base figure. This base figure is usually some element of the statement like total assets, sales, or total expenses. Common size statements help in comparing companies of different sizes and industries by standardizing the data. They are widely used in management accounting for analysis and decision-making.

## Importance of Common Size Statement

Common size statements provide insights into the financial structure of a company. By converting absolute numbers into percentages, it becomes easier to see the relative size of different components and identify trends over time. This analysis can help managers in making informed decisions and evaluating the financial health of the organization.

## Components of Common Size Statement

The common size statement usually consists of the income statement and balance sheet. In the income statement, each line item is expressed as a percentage of total sales. On the balance sheet, each asset and liability item is shown as a percentage of total assets. This standardization allows for easy comparison between companies of different sizes.

## Example of Common Size Statement

Let’s consider Company A and Company B. Company A has total sales of \$1,000,000 and net income of \$200,000. Company B has total sales of \$500,000 and net income of \$100,000. In a common size income statement, the net income for Company A would be 20% (\$200,000/\$1,000,000) and for Company B, it would be 20% (\$100,000/\$500,000). This makes it easier to compare the profitability of both companies.

## Case Study: Common Size Analysis

Company X and Company Y are competitors in the same industry. By using common size statements, Company X analyzes that its cost of goods sold is 60% of sales, while Company Y’s cost of goods sold is 70% of sales. This information helps Company X understand its competitive position and make strategic decisions to improve profit margins.
