Common Size Statement: A Tool for Financial Analysis & Performance

In the vast sea of financial data, making sense of raw numbers can be overwhelming. Companies generate numerous financial reports, but how do you truly compare performance over different periods, or benchmark against competitors of varying sizes? This is where the Common Size Statement emerges as an indispensable analytical tool, transforming absolute figures into powerful, comparable percentages.

What is a Common Size Statement?

A Common Size Statement is a financial statement (either an Income Statement or a Balance Sheet) where each line item is expressed as a percentage of a base figure within the same statement. This conversion standardizes the financial data, eliminating the distortion caused by differences in company size or changes in activity levels over time.

For an Income Statement (or Profit & Loss Statement), the base figure is typically Net Sales Revenue. Every revenue and expense item is then shown as a percentage of this net sales figure.

For a Balance Sheet, the base figure is usually Total Assets (which is always equal to Total Liabilities + Shareholders' Equity). Every asset, liability, and equity item is expressed as a percentage of this total.

This standardization allows for a 'vertical analysis,' making it easy to see the proportional composition of a company's financial structure and operational performance.

Objectives of Common Size Statement

The preparation and analysis of a Common Size Statement serve several crucial objectives for financial analysts, management, investors, and creditors:

Common Size Statement Format & Formula

Preparing a Common Size statement involves a simple but powerful calculation. Each item is divided by the base figure and multiplied by 100 to get a percentage.

Common Size Income Statement Format & Formula

For a Common Size Income Statement, Net Sales Revenue is always taken as 100%.

Formula for each Income Statement item: Percentage of Item=(Absolute Value of Item/Net Sales Revenue​)×100

Common Size Balance Sheet Format & Formula

For a Common Size Balance Sheet, Total Assets (or Total Liabilities & Equity) is always taken as 100%.

Formula for each Balance Sheet item: Percentage of Item=(Absolute Value of Item/Total Assets​)×100

Common Size Statement Analysis

Common Size Statement analysis involves more than just calculating percentages; it's about interpreting what those percentages reveal:

Income Statement Analysis:

• Cost Structure: Track changes in the percentage of COGS, selling, and administrative expenses relative to sales. A rising COGS percentage might indicate rising production costs or less efficient purchasing.
• Profitability Trends: Observe the trends in Gross Profit, Operating Profit, and Net Profit percentages. Are profit margins improving or deteriorating?
• Efficiency: Compare the percentage of operating expenses (selling, administrative) to sales. Lower percentages often indicate better cost control.

Balance Sheet Analysis:

• Asset Composition: Analyze how the company's assets are distributed. Is a larger proportion tied up in fixed assets or current assets? Has cash increased or decreased proportionally?
• Capital Structure: Examine the mix of debt (long-term and short-term liabilities) versus equity used to finance assets. A rising percentage of long-term debt might indicate increased leverage.
• Liquidity & Solvency: While not direct measures, changes in the proportion of current assets to total assets (liquidity) or debt to equity (solvency) can signal shifts.

By comparing these percentages over several periods for the same company (time-series analysis) or against industry averages and competitors (cross-sectional analysis), analysts can uncover underlying strengths, weaknesses, and significant trends that absolute numbers might obscure.

Importance of Common Size Statement

The importance of the Common Size Statement stems from its ability to standardize financial information, offering a clearer, more insightful view:

1. Eliminates Size Bias: It neutralizes the impact of differing company sizes, allowing for true "apples-to-apples" comparisons.
2. Highlights Proportional Changes: It makes changes in the composition of revenues, expenses, assets, or liabilities strikingly clear, even if the absolute values have increased.
3. Aids in Trend Analysis: It is highly effective for spotting trends in cost control, profitability, and financial structure over time.
4. Facilitates Benchmarking: Companies can easily benchmark their performance against industry leaders or competitors, identifying areas where they are more or less efficient.
5. Supports Strategic Decision-Making: Insights derived from common size analysis can inform management decisions related to cost reduction, investment strategies, financing choices, and operational improvements.

Difference Between Common Size and Comparative Statement

While both Common Size Statements and Comparative Statements are tools for financial analysis, they serve distinct purposes and present information differently:

In essence, a Common Size Statement answers the question, "What proportion of this is that?" while a Comparative Statement answers, "How much did this change from then to now?" Both are valuable and often used together for a holistic financial review.

Conclusion

The Common Size Statement is a foundational and incredibly powerful tool in financial analysis. Converting absolute financial figures into relative percentages provides unparalleled clarity, enabling meaningful comparisons across different periods or between disparate entities. Its ability to strip away the noise of scale differences allows for sharp insights into a company's operational efficiency, financial structure, and underlying trends.

For anyone seeking to truly understand the dynamics of a business beyond just its raw numbers, mastering the preparation and analysis of Common Size Statements is an essential step towards robust financial acumen.
