Introduction
Understanding the dynamics of competition within industries is crucial for business strategy and market analysis. The four-firm concentration ratio, a key metric for this analysis, measures the combined market share of the four largest firms within an industry. This ratio provides insights into market competitiveness and industry dominance, facilitating strategic decisions in business planning and investment. When the four largest firms dominate a significant portion of the market, the industry is considered highly concentrated, which could imply less competitive pressures and higher entry barriers for new firms.
To calculate the four-firm concentration ratio, you sum the market shares of the industry's four largest firms. A percentage result indicates how much of the market they control, guiding analysis on market health, competitive dynamics, and economic forecasting. This essential calculation demonstrates industry concentration and market structure effectiveness.
In the following sections, we will explore how Sourcetable lets you calculate the four-firm concentration ratio and more, using its AI-powered spreadsheet assistant, which you can try at app.sourcetable.com/signup.
How to Calculate the 4-Firm Concentration Ratio
The 4-firm concentration ratio is a vital metric used to assess the competitive landscape of an industry. This ratio helps identify markets dominated by the top four firms, indicating potential oligopolistic conditions.
Steps to Calculate the 4-Firm Concentration Ratio
To determine the 4-firm concentration ratio, follow these steps:
1. Identify the four largest companies in your industry of interest.
2. Obtain the market share percentages of these top four companies.
3. Sum up the market shares of these firms. The formula to compute the total market share percentage is: CR4 = S1 + S2 + S3 + S4 , where S1, S2, S3, and S4 represent the market shares of the four largest firms respectively.
4. Express the sum as a percentage to obtain the 4-firm concentration ratio.
This percentage will reveal the extent to which the largest four firms dominate the market, ranging from 0% (no concentration) to 100% (complete concentration).
Interpreting the Results
A higher 4-firm concentration ratio generally suggests less competition and potential oligopoly if the ratio exceeds 60%, indicating that the top firms significantly control the market.
How to Calculate the 4-Firm Concentration Ratio
The 4-firm concentration ratio is an important metric used to analyze the competitive landscape in various industries. This measurement helps determine whether an industry is dominated by a few large companies or has many small competitors.
Steps to Calculate the 4-Firm Concentration Ratio
To start, identify the four largest firms in your industry of interest. You will need accurate data on their market shares.
Next, obtain the market share percentages for these companies. Market share figures are typically available through industry reports, company financial documents, or market research databases.
Finally, sum the market share percentages of these top four firms. The formula to calculate the 4-firm concentration ratio is simply the addition of these percentages: Market Share A + Market Share B + Market Share C + Market Share D.
The resulting percentage, from 0% to 100%, indicates how much of the market is controlled by the top four firms. A higher percentage suggests less competition, often signaling the presence of an oligopoly.
Understanding this ratio allows investors and businesses to make more informed decisions regarding market entry, investment, and competitive strategy.

Examples of Calculating the 4-Firm Concentration Ratio
Example 1: Consumer Electronics Market
Assume four leading firms in the consumer electronics market have market shares of 30%, 25%, 20%, and 15% respectively. The 4-firm concentration ratio is calculated as the sum of these shares: 30% + 25% + 20% + 15% = 90%. This high concentration ratio indicates a market heavily dominated by the top four firms.
Example 2: Automotive Industry
In the automotive sector, four major companies might hold market shares of 22%, 18%, 15%, and 12%. To find the 4-firm concentration ratio, add these values: 22% + 18% + 15% + 12% = 67%. A 67% ratio reflects significant, though not overwhelming, market control by the top firms.
Example 3: Local Grocery Stores
Consider a local market with four grocery stores holding shares of 8%, 7%, 6%, and 5%. The 4-firm concentration ratio is 8% + 7% + 6% + 5% = 26%. This relatively low ratio suggests a competitive market with no dominant player.
Example 4: Tech Startups
If four emerging tech startups capture market shares of 5%, 4%, 3%, and 2%, their 4-firm concentration ratio would be 5% + 4% + 3% + 2% = 14%. This indicates a highly fragmented industry with plenty of room for new entrants and innovation.
Example 5: Pharmaceutical Companies
For pharmaceutical companies with respective market shares of 40%, 30%, 20%, and 10%, the concentration ratio is calculated by summing these percentages: 40% + 30% + 20% + 10% = 100%. This example shows complete market dominance by the top four firms, typical in industries with high barriers to entry and significant regulation.
