How It Works
How to Calculate Market Share
Formula
Market Share = (Company Revenue / Total Market Revenue) x 100
Market share measures your slice of the total pie. A growing market share indicates you are outperforming competitors; a shrinking share means they are gaining ground even if your revenue is growing. The challenge is accurately defining and sizing the total addressable market. Use consistent data sources and timeframes for meaningful comparisons.
Worked Example
Your company earns $5,000,000 in a market worth $50,000,000 total.
- 01Market Share = ($5,000,000 / $50,000,000) x 100 = 10%
- 02Remaining Market = $50,000,000 - $5,000,000 = $45,000,000
Frequently Asked Questions
How do I find total market size?
Use industry reports from firms like Gartner, IBISWorld, or Statista. Government economic data (Census, BLS) provides sector-level figures. Trade associations publish industry statistics. You can also estimate from competitor revenues if public.
Is market share the most important metric?
It is one important indicator but not sufficient alone. A company can have high market share but low profitability. Market share combined with profit margins, growth rate, and customer satisfaction paints a complete competitive picture.
