Common-size financial statements are a powerful tool for comparing companies of different sizes. By expressing financial data as percentages, they allow analysts to easily spot trends, patterns, and differences in financial structures across firms and industries.

These standardized statements facilitate comparative analysis, trend identification, and industry benchmarking. They come in three main types: income statements, balance sheets, and cash flow statements, each offering unique insights into a company's financial health and performance.

Purpose of common-size statements

• Facilitates financial comparison between companies of different sizes by expressing financial statement items as percentages
• Enables analysts to identify trends and patterns in financial data more easily
• Supports decision-making processes for investors, managers, and other stakeholders in business valuation

Comparative financial analysis

• Standardizes financial data to allow direct comparison between companies regardless of size
• Highlights relative proportions of financial statement items (revenue, expenses, assets, liabilities)
• Reveals differences in financial structures and operational efficiencies between firms

Trend identification over time

• Tracks changes in financial statement proportions across multiple periods
• Uncovers shifts in business strategies or market conditions
• Helps predict future financial performance based on historical trends

Industry benchmarking

• Compares a company's financial ratios to industry averages or best-in-class performers
• Identifies areas where a company outperforms or underperforms relative to peers
• Guides strategic decision-making to improve competitive positioning

Types of common-size statements

• Provide a standardized view of financial information for easier analysis and comparison
• Enhance understanding of a company's financial structure and performance relative to its size

Income statement

• Expresses all items as a percentage of total revenue or net sales
• Reveals the proportion of costs and expenses relative to revenue
• Highlights changes in profit margins and expense ratios over time

Balance sheet

• Presents all items as a percentage of total assets
• Shows the relative importance of different asset categories and funding sources
• Facilitates comparison of capital structure and asset allocation across companies

Cash flow statement

• Displays cash flow components as percentages of total cash inflows or outflows
• Illustrates the relative significance of operating, investing, and financing activities
• Helps assess a company's cash generation and usage patterns

Calculation methods

• Involve transforming raw financial data into percentage-based representations
• Enable meaningful comparisons across different time periods and companies

Vertical analysis

• Expresses each line item as a percentage of a base figure within the same period
• Uses total revenue as the base for income statements
• Employs total assets as the base for balance sheets
• Calculation: $(Line \space item \space value \space / \space Base \space figure) \space \space 100$

Horizontal analysis

• Compares financial data over time using a base year as a reference point
• Calculates percentage changes for each line item relative to the base year
• Reveals trends and growth rates in financial performance
• Formula: $((Current \space year \space value \space - \space Base \space year \space value) \space / \space Base \space year \space value) \space \space 100$

Key ratios in common-size analysis

• Encompass current ratio, quick ratio, and cash ratio
• Indicate the company's short-term financial stability and working capital management

Solvency ratios

Efficiency ratios

• Measure how effectively a company utilizes its assets and manages its operations
• Comprise inventory turnover, accounts receivable turnover, and asset turnover ratios
• Indicate the company's operational efficiency and resource management capabilities
