Vertical Analysis: Definition, Examples, and Applications
By Markets & Investing DeskUpdated Nov 10, 2026
Definition
Vertical analysis expresses every line item on a financial statement as a percentage of one base figure from the same period, usually total revenue or total assets.
Key takeaways
- The formula is the line item divided by the base figure, multiplied by 100, and the base always equals 100%.
- Income statements use total revenue as the base, while balance sheets use total assets or total liabilities and equity.
- Common-size statements let a $50 million company be compared with a $5 billion company on cost structure.
- A falling revenue base raises every expense ratio even when actual spending stays flat.
Vertical analysis is a method of financial statement analysis in which every line item is expressed as a percentage of a single base figure from the same statement and the same period. On an income statement the base is usually total revenue (net sales). On a balance sheet it is total assets. A cost of goods sold of $600,000 against revenue of $1,000,000 becomes “60%.” The result shows how large each item is relative to the whole, independent of the company’s size.
Statements presented this way are called common-size financial statements, and the technique is also known as common-size analysis.
How Vertical Analysis Works
The formula
The vertical analysis formula is the same for every statement:
Vertical analysis % = (Line item ÷ Base figure) × 100
The base changes by statement:
| Statement | Typical base figure | What the percentages show |
|---|---|---|
| Income statement | Total revenue or net sales (some analysts use gross sales) | How much of each sales dollar goes to costs, expenses, taxes and profit |
| Balance sheet, assets side | Total assets | The mix of cash, receivables, inventory and long-term assets |
| Balance sheet, financing side | Total liabilities and equity | How the assets are funded: short-term debt, long-term debt, owners’ equity |
| Cash flow statement | Total cash inflows (or total outflows for the outflow items) | Which sources bring in cash and which uses consume it |
Whichever base you choose, use the same one for every period and every company you compare. A margin measured on gross sales will look lower than the same margin measured on net sales, because the denominator is larger.
Steps to compute it
- Pick the statement and the period, and identify the base figure (revenue, total assets, or total cash inflows).
- Divide each line item by the base and multiply by 100.
- Place the percentages in a column next to the dollar amounts.
- Repeat for other periods or companies, then compare the percentage columns rather than the dollar columns.
The base always equals 100%. On a balance sheet, the asset items add up to 100% and the liabilities-plus-equity items add up to 100%. On an income statement, subtotals such as gross profit and operating income carry their own percentages, which are the company’s margins.
Example of Vertical Analysis
Income statement (hypothetical)
Assume a company reports the following for one year, with a 25% tax rate applied to pretax income:
| Line item | Amount | % of revenue |
|---|---|---|
| Revenue | $800,000 | 100% |
| Cost of goods sold | $480,000 | 60% |
| Gross profit | $320,000 | 40% |
| Selling, general and administrative | $160,000 | 20% |
| Operating income | $160,000 | 20% |
| Interest expense | $16,000 | 2% |
| Pretax income | $144,000 | 18% |
| Taxes (25%) | $36,000 | 4.5% |
| Net income | $108,000 | 13.5% |
Read down the percentage column: of every dollar of sales, 60 cents covers product costs, 20 cents covers overhead, and 13.5 cents remains as profit. The gross margin is 40%, the operating margin 20%, the net margin 13.5%.
Balance sheet (hypothetical)
Assume total assets of $2,000,000:
| Assets | Amount | % of total assets |
|---|---|---|
| Cash | $200,000 | 10% |
| Accounts receivable | $300,000 | 15% |
| Inventory | $500,000 | 25% |
| Property, plant and equipment | $1,000,000 | 50% |
On the financing side, current liabilities of $400,000 (20%), long-term debt of $600,000 (30%) and shareholders’ equity of $1,000,000 (50%) total $2,000,000. Half the asset base is funded by owners and half by creditors.
The method also works on non-dollar data. If a company sells 40,000 units, of which 14,000 are product A and 26,000 are product B, product A is 35% of unit sales and product B is 65%.
How Vertical Analysis Is Used
Comparing companies of different sizes
A company with $50 million in revenue and one with $5 billion cannot be compared line by line in dollars. In common-size form they can. If both sell similar goods but one spends 60% of revenue on cost of goods sold and the other 52%, the second has a cost or pricing advantage regardless of scale. The same comparison works against industry norms.
Spotting vertical analysis trends
Running the same common-size statement over several years or quarters turns vertical analysis into a trend tool. Suppose (hypothetically) revenue grows each year, but cost of goods sold rises from 60% to 63% to 66% of revenue. Dollar profits might still increase, yet each sales dollar is becoming less profitable. Vertical analysis of income statement quarters works the same way, though seasonal businesses should be compared with the same quarter of prior years.
Cash flow vertical analysis
On the cash flow statement, each inflow is shown as a share of total inflows and each outflow as a share of total outflows. This reveals, for example, whether most cash comes from operations or from borrowing and asset sales, and whether spending is dominated by capital expenditures, debt repayment or dividends.
Vertical vs. Horizontal Analysis
Horizontal analysis, also called trend analysis, compares the same line item across periods. One year is chosen as the base and later years are expressed as a percentage of it or as a percentage change. If cash was $500,000 in the base year and $705,000 four years later, the later figure is shown as 141% of the base. Period-to-period changes are often stated as year-over-year growth.
| Vertical analysis | Horizontal analysis | |
|---|---|---|
| Compares | Items within one period | One item across periods |
| Base | A total from the same statement | A base year’s value for that item |
| Answers | “How big is this item relative to the whole?” | “How much has this item changed?” |
The two answer different questions. Revenue can grow 20% (horizontal) while marketing expense jumps from 8% to 12% of revenue (vertical). Analysts typically use both, along with ratio analysis, which relates items across statements, such as net income to equity.
Limitations of Vertical Analysis
- No absolute scale. A 30% net margin on $2 million of revenue produces far less profit than a 10% margin on $500 million. Percentages comparing two companies can rank them differently than dollar amounts would.
- Denominator effects. A percentage can change because the base changed, not because the item did. If revenue falls, every expense ratio rises even when spending is flat.
- Accounting differences. Companies classify costs differently (for example, what sits in cost of goods sold versus operating expenses), which can distort cross-company comparisons.
- Industry context. Typical cost and asset structures vary widely between, say, software and retail, so comparisons are most meaningful within the same industry.
- Description, not explanation. Vertical analysis shows that a ratio moved; it does not show why.
The Bottom Line
Vertical analysis helps investors and analysts see a company's cost, margin and funding structure at a glance and compare businesses of very different sizes. It works best with a consistent base across periods and companies, within the same industry, and alongside horizontal and ratio analysis. Because percentages hide absolute scale and do not explain why a ratio moved, the dollar figures still need checking.
