This allows comparison across firms of different sizes or across periods for the same firm.
The Concept: Why Percentages, Not Rupees?
When you look at a company's Profit & Loss statement, you see numbers like "Revenue ₹10,00,000" and "Cost of Goods Sold ₹6,00,000." That tells you the absolute amounts. But what if you want to compare this company with a giant competitor whose revenue is ₹100 crore? The raw rupee figures are useless for comparison — a ₹6 lakh COGS might be 60% of revenue for the small firm but only 0.6% for the large one.
Common size statements solve this problem. They convert every absolute figure into a percentage of a single, meaningful base. This is called vertical analysis — you're analysing each item's proportion within the same period, not across time.
The accounting treatment is straightforward: you take the existing financial statement and add a percentage column. No journal entries, no ledger postings. It's a recasting of existing data, not a new set of books.
The Two Common Size Statements
1. Common Size Income Statement
Base: Revenue from Operations (Net Sales) = 100%
Every other item — Cost of Materials Consumed, Employee Benefit Expenses, Finance Costs, Tax, Net Profit — is expressed as a percentage of this base.
Why this base? Revenue is the primary operating activity. It tells you how much of each rupee earned is consumed by costs, and how much remains as profit. A rising percentage for "Employee Benefits" over three years, for example, signals that labour costs are growing faster than sales — a red flag.
2. Common Size Balance Sheet
Base: Total Assets (or Total Equity & Liabilities) = 100%
Every asset (Current, Non-current) and every claim (Shareholders' Funds, Non-current Liabilities, Current Liabilities) is shown as a percentage of the total.
Why this base? It reveals the composition of the company's resources and funding. A company with 80% fixed assets is capital-intensive (manufacturing); one with 80% current assets is likely a trading or service firm. On the liabilities side, a rising percentage of debt signals increasing financial risk.
Example: A Simple Trading Company
Let's take a small company, ABC Traders, with the following data for the year ended 31st March 2024:
| Item | Amount (₹) |
|---|---|
| Revenue from Operations | 5,00,000 |
| Cost of Goods Sold | 3,00,000 |
| Employee Benefit Expenses | 80,000 |
| Depreciation | 20,000 |
| Other Expenses | 30,000 |
| Tax @ 30% | 21,000 |
| Net Profit | 49,000 |
Balance Sheet as on 31st March 2024:
| Item | Amount (₹) |
|---|---|
| Assets | |
| Non-current Assets (Fixed Assets) | 3,00,000 |
| Current Assets (Inventory, Debtors, Cash) | 2,00,000 |
| Total Assets | 5,00,000 |
| Equity & Liabilities | |
| Shareholders' Funds (Equity) | 3,50,000 |
| Non-current Liabilities (Loan) | 1,00,000 |
| Current Liabilities (Creditors) | 50,000 |
| Total Equity & Liabilities | 5,00,000 |
Step 1: Common Size Income Statement
Base = Revenue from Operations = ₹5,00,000 = 100%
| Particulars | Absolute Amount (₹) | Common Size Percentage |
|---|---|---|
| Revenue from Operations | 5,00,000 | 100.00% |
| Less: Cost of Goods Sold | (3,00,000) | (60.00%) |
| Gross Profit | 2,00,000 | 40.00% |
| Less: Employee Benefit Expenses | (80,000) | (16.00%) |
| Less: Depreciation | (20,000) | (4.00%) |
| Less: Other Expenses | (30,000) | (6.00%) |
| Profit Before Tax | 70,000 | 14.00% |
| Less: Tax @ 30% | (21,000) | (4.20%) |
| Net Profit | 49,000 | 9.80% |
How each percentage is calculated:
- Cost of Goods Sold % = (3,00,000 / 5,00,000) × 100 = 60%
- Gross Profit % = (2,00,000 / 5,00,000) × 100 = 40%
- Employee Benefits % = (80,000 / 5,00,000) × 100 = 16%
- Net Profit % = (49,000 / 5,00,000) × 100 = 9.8%
The percentages in a common size Income Statement should always add up vertically: Gross Profit % + all expense % = 100% (before tax). Here: 40% Gross Profit minus 16% minus 4% minus 6% = 14% PBT, then minus 4.2% tax = 9.8% Net Profit. This cross-check catches calculation errors.
Step 2: Common Size Balance Sheet
Base = Total Assets (or Total Equity & Liabilities) = ₹5,00,000 = 100%
| Particulars | Absolute Amount (₹) | Common Size Percentage |
|---|---|---|
| ASSETS | ||
| I. Non-current Assets | ||
| Fixed Assets | 3,00,000 | 60.00% |
| II. Current Assets | ||
| Inventory, Debtors, Cash | 2,00,000 | 40.00% |
| Total Assets | 5,00,000 | 100.00% |
| EQUITY & LIABILITIES |
