Horizontal vs vertical analysis answers two different questions: what changed across periods, and what each line item represents within one statement.
财务报表横向分析与纵向分析回答两个不同问题：多个期间发生了什么变化，以及单期报表中每个项目占基准项目的多少。
Horizontal analysis, also called trend analysis, moves across reporting periods. It compares the same line item—revenue, inventory, operating income, or cash—from one period to another. Vertical analysis moves within one statement. It converts each line item into a percentage of a selected base, creating a common-size financial statement.
横向分析也称趋势分析，沿着报告期间展开，比较收入、存货、营业利润或现金等同一项目在不同期间的变化。纵向分析则在同一张报表内部展开，把每个项目换算为某个基准项目的百分比，形成共同百分比财务报表。
Measures absolute change, percentage change, direction, volatility, and multi-period trend.
衡量绝对变化、百分比变化、方向、波动以及多个期间的趋势。
Measures composition, cost structure, margins, financing mix, and relative scale.
衡量报表构成、成本结构、利润率、融资结构和相对规模。
The methods are complementary rather than competing. Horizontal analysis can reveal that cost of goods sold rose 25%; vertical analysis can reveal that it also consumed a larger share of revenue. The first finding identifies movement. The second explains structural significance.
两种方法互补而非互斥。横向分析可能发现销售成本增长了25%；纵向分析则进一步发现销售成本占收入的比例也上升了。前者识别变化，后者说明这种变化对报表结构意味着什么。
Use absolute change and percentage change together. A large percentage calculated from a tiny base can look dramatic while being economically small. For vertical analysis, name the denominator explicitly so another analyst can reproduce the result.
绝对变化与百分比变化应配合使用。基期金额很小时，即使经济影响不大，也可能产生夸张的增长率。做纵向分析时，应明确写出分母，确保其他分析者能够复算。
Percentage change from zero is undefined. Do not replace it with 100% or an arbitrary number. Report the absolute movement and mark the percentage as not meaningful. A negative base can also reverse the intuitive sign of a percentage; explain the transition in words, especially when a company moves from a loss to a profit.
从零开始的百分比变化在数学上没有定义，不能用100%或任意数字替代。应报告绝对变化，并把百分比标记为“不适用”或“无意义”。基期为负数时，百分比符号也可能违背直觉，特别是企业由亏损转为盈利时，应使用文字解释变化。
The following fictional income statement uses simplified figures solely to demonstrate the calculation. Amounts are in millions. It is not a real company, forecast, recommendation, or performance claim.
下面使用虚构且简化的利润表演示计算，金额单位为百万。案例不代表真实公司、预测、投资建议或业绩承诺。
| Income statement item利润表项目 | 2024 | 2025 | Dollar change绝对变化 | Horizontal %横向变动率 | 2024 vertical %2024纵向占比 | 2025 vertical %2025纵向占比 |
|---|---|---|---|---|---|---|
| Revenue收入 | 1,000 | 1,200 | +200 | +20.0% | 100.0% | 100.0% |
| Cost of goods sold销售成本 | 600 | 750 | +150 | +25.0% | 60.0% | 62.5% |
| Operating expenses营业费用 | 200 | 240 | +40 | +20.0% | 20.0% | 20.0% |
| Net income净利润 | 120 | 138 | +18 | +15.0% | 12.0% | 11.5% |
A horizontal-only conclusion might say the business improved because revenue and net income increased. The vertical view adds an important qualification: cost structure deteriorated and net margin compressed. The next research question is not “Did profit rise?” but “Why did input costs, product mix, pricing, or operating leverage prevent profit from keeping pace with revenue?”
只看横向结果，可能会因为收入和净利润增加而判断经营改善。纵向结果增加了重要限定：成本结构恶化，净利率收窄。下一步研究不应停留在“利润是否增长”，而应追问原材料成本、产品组合、定价或经营杠杆为何让利润没有跟上收入增速。
Vertical analysis is only meaningful when the base matches the statement and the analytical question. Revenue is conventional for an income statement. Total assets are conventional for the asset side of a balance sheet. Liabilities and equity can be related to total liabilities and equity, which equals total assets under the accounting equation.
纵向分析是否有意义，取决于基准项目是否与报表类型和分析问题匹配。利润表通常以收入为基准；资产负债表资产端通常以总资产为基准；负债和权益也可用负债与权益合计作为基准，根据会计恒等式，该金额等于总资产。
Common-size percentages reduce the effect of absolute company size, making vertical analysis useful for peer comparison. They do not eliminate accounting differences. Align fiscal periods, currencies, consolidation scope, discontinued operations, and line-item definitions before drawing conclusions.
共同百分比可以减弱企业绝对规模对比较的影响，因此纵向分析适合同行比较。但它不能消除会计差异。得出结论前，应统一财政年度、币种、合并范围、终止经营项目和报表项目定义。
Reliable analysis starts before the formulas. It requires consistent periods, units, statement versions, and field definitions. QVeris can support the capability-discovery and data-retrieval steps; the arithmetic should remain explicit and deterministic.
可靠分析从计算公式之前开始，需要统一期间、单位、报表版本和字段定义。QVeris可以支持能力发现与数据获取步骤，而计算逻辑应保持明确、确定且可复算。
Specify company, statement, annual or quarterly frequency, comparison window, currency, and whether the objective is trend, structure, or peer comparison.
明确公司、报表、年度或季度频率、比较区间、币种，以及目标是趋势、结构还是同行比较。
Use QVeris to discover and inspect relevant financial-data capabilities, including FMP statement endpoints where available, then request the needed periods and fields.

Align units, signs, fiscal periods, restated figures, and field meaning. Keep missing values distinct from zeros.

Compute absolute and percentage changes across periods, then compute common-size percentages within each period. Preserve the exact formulas.

Use filings, notes, segment disclosures, management commentary, and industry context to explain material movements rather than treating percentages as causes.
