1. What is a Common Size Income Statement?
A common size income statement presents each item as a percentage of revenue, providing a standardized view for financial analysis. This format is useful in evaluating financial performance and in making sound business decisions. According to a 2024 study by the University of Texas at Austin’s McCombs School of Business, the common size income statement’s presentation of items as a percentage of revenue helps to easily compare the financial performance across different periods or companies, regardless of size.
1.1 What Are the Key Benefits of Using a Common Size Income Statement?
The key benefits include simplified financial comparisons, identification of trends, and improved decision-making. Here’s a closer look:
- Simplified Financial Comparisons: It enables easier comparison of financial data across different periods or between companies of varying sizes, as stated in a report by Harvard Business Review.
- Trend Identification: It helps identify trends in revenue, costs, and profitability over time.
- Improved Decision-Making: Businesses make informed decisions based on the identified trends and comparisons.
1.2 How Does a Common Size Income Statement Differ from a Regular Income Statement?
Unlike a regular income statement, which shows absolute dollar amounts, a common size income statement displays each item as a percentage of total revenue. This normalized format allows for comparative analysis.
Here’s a simple comparison:
| Feature | Regular Income Statement | Common Size Income Statement |
|---|---|---|
| Data Presentation | Absolute dollar amounts | Percentage of total revenue |
| Comparative Analysis | Difficult across different sizes | Easy, standardized comparison |
| Focus | Total financial values | Proportional financial values |
| Identifying Trends | Complicated | Simplified |
1.3 What Are the Primary Use Cases for a Common Size Income Statement?
The primary use cases include benchmarking against competitors, analyzing internal performance trends, and attracting investors by showcasing financial stability.
| Use Case | Description |
|---|---|
| Benchmarking | Comparing a company’s financial performance against industry averages or key competitors to identify areas of strength and weakness. |
| Internal Trend Analysis | Evaluating changes in revenue, costs, and profitability over multiple periods to detect emerging patterns and inform strategic decisions. |
| Attracting Investors | Presenting financial data in a standardized format that highlights financial stability and growth potential. |
1.4 What Is the Formula to Calculate Common Size Income Statement Items?
To calculate a common size income statement item, divide the line item amount by total revenue and multiply by 100 to get the percentage. The formula is:
(Line Item Amount / Total Revenue) * 100
For example, if Cost of Goods Sold (COGS) is $500,000 and Total Revenue is $2,000,000, the common size percentage for COGS is:
($500,000 / $2,000,000) * 100 = 25%
2. How to Prepare a Common Size Income Statement
Preparing a common size income statement involves several steps, from gathering financial data to calculating percentages and presenting the final statement. Understanding each step ensures accuracy and relevance.
2.1 What Data Do You Need to Collect?
Collect all line items from the income statement, including revenue, cost of goods sold (COGS), operating expenses, interest expenses, and taxes. Ensure the data is accurate and covers the period being analyzed.
Here’s a checklist of essential data:
- Revenue: Total sales and any other income sources.
- Cost of Goods Sold (COGS): Direct costs associated with producing goods or services.
- Gross Profit: Revenue minus COGS.
- Operating Expenses: Costs incurred from normal business operations.
- Interest Expenses: Costs of borrowing money.
- Taxes: Income taxes paid.
- Net Income: The final profit after all expenses and taxes.
2.2 What Steps Are Involved in Creating a Common Size Income Statement?
The steps involve identifying the base figure (usually total revenue), dividing each line item by this base, and multiplying by 100 to express each item as a percentage. The steps are shown below:
- Identify Base Figure: Total Revenue.
- Divide Each Line Item: Divide each item by total revenue.
- Multiply by 100: Convert each result to a percentage.
- Present the Statement: Display all items as percentages.
2.3 How Can Excel Help in Preparing a Common Size Income Statement?
Excel can automate calculations, create visually appealing statements, and facilitate comparisons. Use formulas to calculate percentages and charts to visualize the data.
Here’s how you can use Excel:
- Enter Data: Input the income statement data into columns.
- Calculate Percentages: Use formulas to divide each line item by total revenue and multiply by 100. For example, if total revenue is in cell B1 and COGS is in cell B2, the formula in cell C2 would be
=(B2/B1)*100. - Create Charts: Use Excel’s charting tools to create graphs that visualize the common size income statement.
- Use Pivot Tables: Pivot tables can quickly summarize and analyze large datasets, making it easier to create a common size income statement.
2.4 What Are Common Pitfalls to Avoid When Creating a Common Size Income Statement?
Common pitfalls include using incorrect data, misinterpreting percentages, and failing to compare data with industry benchmarks. Accuracy and context are crucial.
Here are some points to avoid:
- Inaccurate Data: Double-check all data entries to ensure accuracy.
- Misinterpreting Percentages: Understand the implications of each percentage in the context of the business.
- Lack of Benchmarking: Compare the common size income statement with industry averages or competitors to gain valuable insights.

3. Interpreting a Common Size Income Statement
Interpreting a common size income statement involves understanding what the percentages reveal about a company’s operational efficiency, profitability, and financial health.
3.1 How Do You Analyze Cost of Goods Sold (COGS) in a Common Size Income Statement?
A high COGS percentage indicates that a large portion of revenue is spent on production, potentially squeezing profit margins. Investigate ways to reduce production costs or increase prices.
Here’s what to look for:
- Trend Analysis: Look for changes in the COGS percentage over time. An increasing percentage may indicate rising costs of materials or inefficient production processes.
- Benchmarking: Compare the company’s COGS percentage to industry averages. A significantly higher percentage suggests the company is less efficient than its competitors.
- Root Cause Analysis: Investigate the reasons behind high COGS.
3.2 What Does a High or Low Operating Expense Percentage Indicate?
A high operating expense percentage could signal inefficiencies in managing overhead costs. A low percentage might indicate strong cost control or underinvestment in essential areas like marketing or R&D.
Consider the following points:
- High Percentage: Look for areas where operating expenses can be reduced. This could involve streamlining administrative processes, negotiating better deals with suppliers, or reducing marketing costs.
- Low Percentage: Ensure that essential investments are not being neglected.
- Industry Standards: Compare the operating expense percentage to industry averages.
3.3 How Can You Use a Common Size Income Statement to Identify Profitability Issues?
By examining gross profit margin and net profit margin percentages, you can identify areas where profitability is underperforming. Declining margins may necessitate strategic adjustments.
Steps to identifying profitability issues:
- Calculate Gross Profit Margin: (Gross Profit / Total Revenue) * 100.
- Calculate Net Profit Margin: (Net Income / Total Revenue) * 100.
- Analyze Trends: Look for declines in these margins over time.

5.2 How Do You Calculate Percentage Changes in a Common Size Income Statement?
To calculate the percentage change, subtract the previous period’s value from the current period’s value, divide by the previous period’s value, and multiply by 100. The formula is:
((Current Period Value - Previous Period Value) / Previous Period Value) * 100
For example, if revenue in 2024 is $2,200,000 and it was $2,000,000 in 2023, the percentage change is:
(($2,200,000 - $2,000,000) / $2,000,000) * 100 = 10%
