What is Horizontal Analysis?
Horizontal analysis, also called trend analysis, is the technique of comparing financial statement line items across two or more consecutive periods to identify changes in absolute and percentage terms. It highlights growth patterns, contractions, and emerging risks in revenue, expenses, asset balances, and cash flow over time.
How It Works
- Select a base period as the starting point.
- Compute the absolute change: Current Period – Base Period.
- Compute the percentage change: Change / Base Period * 100.
- Apply consistently across the income statement, balance sheet, and cash flow statement.
- Interpret in context: industry conditions, one-off events, and inflation can distort trends.
Saudi Context
Tadawul-listed companies publish horizontal trend tables in MD&A sections of annual reports. Saudi auditors use horizontal analysis as an analytical procedure to identify unusual fluctuations triggering further substantive testing. Multi-year horizontal analysis of cash flows is also a key input to credit assessments by Saudi banks.
Example
A company’s revenue: 2023 = SAR 80m, 2024 = SAR 92m, 2025 = SAR 110m. Horizontal change 2023 to 2025 = +SAR 30m (+37.5%). Reading the trend: revenue grew 15% then 19.6%, signaling accelerating top line worth deeper investigation.
