Horizontal Analysis provides businesses a method to examine financial statement entries by looking at the documents’ number for a specific accounting time frame compared to the same length of a historical period for the same accounting line item.
Breaking the Process Down
It’s a way to measure trends and variances by looking at the current year’s values versus the reference year. This helps an analyst figure out if the values increase or decrease. It’s either done on an absolute value or a percentage change basis. The analysis provides a company’s growth and financial position against competitors.
This method is different compared to vertical analysis because vertical analysis looks at a single reporting period and measures the proportional relationship between items, compared to horizontal analysis evaluating multiple periods and multiple ratios for a more comprehensive approach.
Generally Accepted Accounting Principles (GAAP) require uniform and standardized financial statements for adequate financial statement analysis. This entails consistent accounting practices and fundamental principles being employed annually. Comparability constraints mandates that the business’ financial statements are in a form that permits analysts to evaluate them against other competitors in the same field. This is where horizontal analysis comes into play, creating consistency.
This analysis determines what impacts a company’s growth over time. For cyclical or seasonal companies, it lets analysts get a handle on what’s normal and what’s not. It also permits identification of variances in different product/business segments and how to project a company’s future performance.
Along with the three financial statements (balance sheet, cash flow statement, and income statement) providing working outcomes, it can similarly identify issues and strengths by looking at certain metrics like profit margins or the rate of inventory changing hands.
If a company reports higher earnings per share due to increases in revenue or lowers its figures of the COGS (cost of goods sold), analysts looking at the interest coverage ratio or cash flow-to-debt ratio, for example, can use horizontal analysis to gauge if a business has enough liquidity for continued operations.
Real World Example of Horizontal Analysis
Let’s say Company X had revenue of $100 million in the previous year and accounts receivable of $200 million during the “base year.” This is compared to revenue of $300 million in the present year and accounts receivable of $600 million. Based on these numbers, the calculations are as follows:
Revenue Comparison
[($300 million – $100 million)/$100 million)] x 100 = 200 percent
Accounts Receivable
[($600 million – $300 million)/$300 million)] x 100 = 100 percent
When it comes to interpreting horizontal analysis, the process needs context to ensure it’s used appropriately. The most prominent consideration is understanding what contributed to the base year’s numbers and the current year’s numbers. Did the company sell off a segment that increased profitability, or did they face massive lawsuits or spend excessive amounts of capex to ensure their viability and competitiveness in the upcoming years?
The calculation is straightforward, but being able to delve into what happened – and why – is the role of the business owner and investor to determine the true health of the business.
