Vertical analysis expresses each income statement item as a percentage of what base?

• A. Total Assets
• B. Net Income
• C. Operating Income
• D. Total Revenue

Answer: (D)

Vertical analysis on the income statement uses total revenue as the base. This standardizes each line item as a percentage of revenue, making it easy to compare cost structure and profitability across firms or periods regardless of size. For example, COGS, operating expenses, and taxes are all shown as a portion of revenue, so you can see how much of each revenue dollar goes to costs and how much remains as profit. Using total assets would be a balance sheet approach, not applicable here, and using net income or operating income as the base would defeat the purpose of comparing relative sizes across different companies.
