Market share refers to the percentage of total sales, revenue, or customers that a company controls within a specific market or industry over a defined period. It is one of the most important metrics used to evaluate a company’s competitive position and performance.

What is market share?

Market share shows how large a company is compared to its competitors. It indicates the portion of an industry’s total demand that a business captures through its products or services.

For example, if the total smartphone market revenue is $100 billion and a company generates $25 billion in sales, its market share is 25%.

How is market share calculated?

The basic formula is

Market Share (%) = (Company Sales ÷ Total Market Sales) × 100

Example:

• Company revenue: $50 million
• Total industry revenue: $500 million

Market Share = (50 ÷ 500) × 100 = 10%

Market share can also be calculated based on:

• Units sold
• Customer base
• Subscription numbers
• Geographic market penetration

Types of Market Share

1. Revenue Market Share

Measures are based on the total sales value. Most commonly used in industry reports.

2. Unit Market Share

Based on the number of products sold rather than revenue.

3. Customer Market Share

Shows the percentage of total customers served in a market.

4. Relative Market Share

Compares a company’s share against its largest competitor.

Why Market Share is Important

Higher market share usually means stronger brand recognition and customer trust.

2. Shows Market Leadership
