Market Growth vs Your Revenue Growth
What is Market Share Growth?
Market share growth measures how your company's portion of the total market is expanding over time. It's calculated as your revenue divided by total market size, expressed as a percentage. Growing market share requires understanding market dynamics, competitive positioning, and the relationship between overall market growth and your revenue growth.
The TAM (Total Addressable Market), SAM (Serviceable Available Market), and SOM (Serviceable Obtainable Market) framework helps prioritize growth strategies. TAM represents the total revenue opportunity, SAM is the portion you can serve, and SOM is what you can realistically capture. Focus on SOM for realistic planning. For revenue projections, use our Revenue Growth Calculator to see how market share growth translates to revenue.
How to Use This Calculator
Enter your current market share percentage, target market share, total market size, expected annual market growth rate, and years to reach the target. The calculator shows current revenue, target revenue, required growth rate, market size at target year, and revenue growth needed.
Use the chart to visualize how market size and your revenue grow over time. Understanding the relationship between market growth and your growth helps you see what's needed to gain market share.
Formula Explained
The market share growth calculation projects revenue and market size:
Market Size (Year N) = Market Size × (1 + Growth Rate)^N
Target Revenue = Market Size (Target Year) × (Target Share / 100)
Required Growth Rate = ((Target Revenue / Current Revenue)^(1/Years) - 1) × 100

Tips for Best Results
- Focus on realistic targets: Base market share targets on market dynamics, competitive landscape, and your capabilities. Aggressive targets without a plan are unrealistic.
- Understand market growth: If the market is growing, you need to grow faster than the market to gain share. If the market is shrinking, maintaining revenue might still gain share.
- Consider TAM, SAM, SOM: Focus on SOM (Serviceable Obtainable Market) for realistic planning. TAM is aspirational, but SOM is achievable.
- Grow profitably: Market share without profitability isn't sustainable. Focus on growing share with strong unit economics and positive margins.
- Monitor competitive dynamics: Track competitor market share and growth rates. Understand how competitive actions affect your ability to gain share.
- Track revenue growth: Use our Revenue Growth Calculator to project how revenue growth contributes to market share gains.
Frequently Asked Questions
What is market share growth?
Market share growth measures how your company's portion of the total market is expanding over time. It's calculated as your revenue divided by total market size. Growing market share requires understanding market dynamics, competitive positioning, and the relationship between market growth and your revenue growth.
How do I calculate market share?
Market share = (Your Revenue / Total Market Size) × 100. To grow market share, your revenue must grow faster than the overall market. If the market grows 10% annually and you grow 20%, you're gaining market share. If you grow slower than the market, you're losing share even if revenue increases.
What's the difference between TAM, SAM, and SOM?
TAM (Total Addressable Market) is the total revenue opportunity if you captured 100% of the market. SAM (Serviceable Available Market) is the portion of TAM you can realistically serve with your product. SOM (Serviceable Obtainable Market) is the portion of SAM you can capture in the near term. Focus on SOM for realistic planning.
How do I grow market share?
Grow market share by increasing revenue faster than market growth. Strategies include: improving product-market fit, expanding into new segments, increasing customer acquisition, reducing churn, improving pricing, and competitive differentiation. Focus on sustainable growth with strong unit economics.
What's a good market share?
Good market share varies by industry and market maturity. In fragmented markets, 5-10% might be strong. In concentrated markets, 20-30%+ might be needed for leadership. Focus on growing share profitably rather than just maximizing share. Market share without profitability isn't sustainable.
