What is Trend Analysis - Meaning, Formula, Example, & How to do

Trend analysis is a statistical technique used to identify patterns and trends in data, over time. This technique is widely used in several fields, including finance, economics and marketing, to forecast future trends and make informed decisions. In this article, we discuss what trend analysis is: its meaning and the formula to conduct trend analysis.

What is trend analysis?

Trend analysis is a technique used in financial analysis to identify patterns and trends in a company's financial data. It involves comparing financial data to identify trends and practices to help analysts and investors make informed decisions about a company's financial health and prospects.

Trend analysis can be applied to various financial metrics, such as revenue, profits, margins, and expenses, to help identify company performance trends. Investors and analysts can gain insights into a company's performance by analysing trends, identifying potential risks and opportunities. This information can later help in making better and informed investment decisions.

Meaning of trend analysis

Trend analysis is the process of examining a company's financial information over a specific time period to detect patterns and trends in its performance. This method can aid investors and analysts in recognising potential hazards and opportunities in a company's financial well-being, resulting in more informed investment decisions.

Financial indicators such as revenue, profits, margins, and expenses can be utilised to perform trend analysis. Analysts can pinpoint trends and patterns that offer insights into a company's financial performance and future prospects by comparing these metrics over time.

Formula for trend analysis

The trend analysis formula can differ based on the financial metrics under consideration.

However, the general approach involves computing the percentage change in the metric during a particular period. The formula is as follows:

Percentage change = [(Current value - Previous value) / Previous value] x 100

For instance, if an analyst wants to determine the percentage change in revenue over two years, they would use the following equation:

Percentage change in revenue = [(Current year revenue - Previous year revenue) / Previous year revenue] x 100

After computing the percentage change, the analyst can graph the information to detect trends or patterns.

How to do trend analysis

Trend analysis involves analysing a company's financial data over some time to identify patterns and trends in its performance. Here are the steps involved in trend analysis.

Step 1: Gather the financial data

The first step in trend analysis is gathering the financial data for the company. This data can be found in the company's financial statements, such as the income statement, balance sheet and cash flow statement. Analysts may also use financial databases and tools to access and analyse the financial data.

Step 2: Choose the financial metrics to be analysed

The next step is to choose the financial metrics to analyse. The selected metrics will depend on specific analysis and research goals. For example, an investor may focus on revenue and profit margins to determine a company's growth potential and profitability.

Step 3: Calculate the percentage change

After the financial metrics have been selected, the analyst can calculate the percentage change in each metric over a period using the formula described earlier. The analyst should choose a relevant period for the analysis and provide enough data to identify trends and patterns.

Step 4: Plot the data on a graph

After calculating the percentage change in the financial metrics, the analyst can plot the data on a graph to identify trends and patterns. Line graphs are commonly used for trend analysis, as they give analysts a visual to note the changes in data over time.

Step 5: Analyse the trends and patterns

The final step in trend analysis is to analyse the trends and patterns identified in the data. Analysts should look for changes in the data that are significant and consistent over time. They should also consider external factors that may have influenced the data, such as changes in the market or industry.

Trend analysis: The different approaches

Several types of trend analysis can be used to identify patterns and predict future trends. One common approach is time-series analysis, which involves analysing data over some time to identify trends and patterns. Another approach is the moving average analysis, which calculates the average of a set of data points over a specific period.

Seasonal analysis is another trend analysis involving data for seasonal variations, such as holiday shopping patterns. Cycle analysis involves analysing data to identify recurring patterns or cycles, such as economic or weather patterns. Finally, regression analysis is a statistical approach that analyses the relationship between two variables to identify trends and make predictions.

Each type of trend analysis has its strengths and weaknesses. The most appropriate approach will depend on the data being analysed and the research goals.

Benefits of trend analysis

Trend analysis is an essential tool in order to make informed business decisions. By analysing trends, organisations can identify patterns and predict future performance. Some of the benefits of trend analysis include:

  1. Identifying opportunities: By analysing trends, organisations can identify emerging market opportunities and make strategic decisions to capitalise on these.
  2. Forecasting future performance: Trend analysis gives companies the opportunity to forecast performance based on historical data. This helps businesses make informed decisions about investments, staffing and other vital areas.
  3. Tracking progress: Trend analysis enables organisations to track progress and identify areas of improvement. This helps organisations stay on track with their goals and make necessary adjustments to their strategies.
  4. Risk management: By monitoring trends, organisations can identify and proactively mitigate potential risks.


Trend analysis is a helpful technique to analyse a company's financial data and identify patterns and trends in its performance.
