Understanding Horizontal Analysis

Horizontal analysis, also known as trend analysis, involves reviewing financial statements over multiple periods. This method allows you to observe changes and trends over time, providing a clear picture of business growth and areas that require attention.

Key Steps in Horizontal Analysis

Step 1: Select Time Periods

Choose consistent time periods to compare, such as quarterly or annually.

Step 2: Calculate Percentage Changes

Determine the percentage change for each line item from one period to the next.

Step 3: Analyze Trends

Identify significant trends or deviations and investigate their causes.

The Role of Vertical Analysis

Vertical analysis simplifies the financial review process by expressing each line item as a percentage of a base figure, such as total sales. This method is particularly useful for comparing companies of different sizes or assessing performance over time.

Implementing Vertical Analysis

Step 1: Establish a Base Figure

Decide on a base figure, typically total sales or revenue, for comparison.

Step 2: Convert Line Items

Express each line item as a percentage of the base figure.

Step 3: Compare Against Standards

Evaluate results against industry standards or historical data.
