Horizontal and vertical analysis
Financial statement analysis turns raw numbers into insight. Horizontal and vertical analysis are the first tools analysts reach for.
Why analyse statements
Investors, lenders, managers, and regulators analyse financial statements to judge profitability, liquidity, solvency, and efficiency, to compare with competitors, and to spot trends or warning signs. Analysis always needs context: industry norms, economic conditions, and the company's strategy.
Horizontal analysis
Horizontal (trend) analysis compares line items across periods. Percentage change = (current year - base year) / base year x 100. If revenue rose from 400,000 to 460,000 dollars, it grew 15%. Comparing growth rates across items, such as revenue growing 15% but expenses growing 25%, reveals pressure on margins.
Trend percentages
For longer periods, trend percentages express each year's amount as a percentage of a base year. If base-year sales are 100%, and later years are 108%, 117%, and 130%, the trend shows accelerating growth. Trends help separate one-off changes from lasting patterns.
Vertical analysis
Vertical (common-size) analysis expresses each item as a percentage of a base within the same statement: on the income statement, each item as a percentage of net sales; on the balance sheet, each item as a percentage of total assets. A cost of goods sold of 60% of sales means 40 cents of each sales dollar remains as gross profit.
Common-size comparisons
Common-size statements allow comparisons between companies of different sizes. A small firm and a giant competitor can be compared by seeing whether each spends a similar share of sales on marketing or carries a similar share of assets as inventory.
Benchmarks
Analysts compare a company with its own past results, with competitors, and with industry averages, available from sources such as financial databases and trade associations. A ratio is only good or bad relative to sensible benchmarks: grocery stores normally have thin margins, while software companies often have high margins.
Limits of analysis
Analysis has limits: statements use historical costs and estimates; companies may choose different accounting methods (such as FIFO versus LIFO); one-off items can distort comparisons; inflation can make trends misleading; and numbers do not capture everything, such as brand strength or management quality.
Worked example
Company X's income statement shows net sales of 2,000,000 dollars, COGS of 1,300,000, operating expenses of 500,000, and net income of 140,000. Common-size: COGS 65%, gross profit 35%, operating expenses 25%, net income 7%. Last year, COGS was 62% of sales; the 3-point rise suggests rising input costs or price cuts worth investigating.
Key takeaways
Statement analysis assesses profitability, liquidity, solvency, and efficiency in context. Horizontal analysis compares items over time using percentage changes and trend percentages. Vertical analysis expresses items as percentages of sales or total assets. Common-size statements enable comparisons between companies of different sizes. Benchmarks include past results, competitors, and industry averages. Analysis is limited by estimates, accounting choices, one-off items, and inflation.
