For any independent insurance agency owner, growth is a critical measure of health and a key driver of valuation. However, growth is rarely a straight line. It ebbs and flows, influenced by broad economic forces that create distinct patterns over time. By analyzing historical revenue growth trends, we can gain valuable perspective on how agencies of different sizes navigate economic cycles—and what it means for buyers and sellers in today’s market. Historical data reveals two very different growth stories when comparing small and medium-sized agencies, offering powerful insights for strategic planning.
A Tale of Two Growth Stories
The path to growth often looks different depending on an agency’s size. Smaller agencies tend to be more agile and responsive to market shifts, while medium- to large-sized agencies often exhibit greater stability.

| Agency Profile Metric | $500,000 and Less | $500K to $1M | $1M to $2M | $2M to $3M | $3M and Over |
|---|---|---|---|---|---|
| Average Annual Growth | 15% | 8% | 12% | 3% | 8% |
| Top 25% | 44% | 17% | 29% | 7% | 15% |
Key Takeaway: Top Performers Achieve Dramatically Higher Growth
The most significant differentiator is the Annual Revenue Growth. In every revenue category, the top-performing agencies grow at a much faster rate than the average. For instance, in the $1M-$2M range, top performers grew by 29%, more than double the average of 12%. This indicates a more aggressive and successful approach to new business development.
Key Takeaway: Growth Strategies Vary by Agency Size
While all top performers grow faster than average, their growth rates vary. The highest percentage growth is seen in the smallest (44%) and mid-sized (29%) categories, where it is easier to achieve large percentage gains on a smaller revenue base. The largest agencies still achieve an impressive 15% growth, double the average for their size, demonstrating that even large, established firms can drive aggressive growth.

| Agency Size | ’92-’93 | ’94-’95 | ’96-’97 | ’99-’00 | ’02-’03 | ’06-’07 | ’10-’11 | ’13-’14 | ’18-’19 |
|---|---|---|---|---|---|---|---|---|---|
| Small | 5% | 5% | 7% | 9% | 8% | 11% | 13% | 21% | 10% |
| Medium | 5% | 4% | 9% | 9% | 12% | 8% | 0% | 8% | 9% |
| Large | 3% | 11% | 8% | 9% | 14% | 12% | 0% | 9% | 6% |
Small Agencies: Volatility and High Potential
The average annual revenue growth for small agencies clearly mirrors the wider economy’s health. Key trends include:
- Modest Beginnings: Growth was steady but moderate through the 1990s.
- Pre-Recession Acceleration: Growth picked up in the mid-2000s as the economy expanded.
- A Post-Recession Spike: Following the Great Recession, smaller agencies saw a dramatic surge in growth, peaking at an average of 21% in the 2013-2014 period. This likely reflects their ability to adapt quickly and capitalize on opportunities in a strong recovery.
- A New Normal: In more recent years, growth has leveled off to a still-impressive average of $10%$, demonstrating sustained health.
This pattern suggests that small agencies are nimble enough to seize opportunities during economic upswings, leading to periods of explosive growth.
Medium Agencies: The Power of Stability
Medium-sized agencies have demonstrated a more consistent, if less spectacular, growth trajectory. Their journey is marked by stability:
- Steady Performance: Since the late 1990s, growth has reliably fluctuated between 8% and 12%.
- Recessionary Impact: The primary exception was a dip to 0% growth in the period immediately following the 2008 financial crisis, showcasing their vulnerability to major economic shocks.
- Moderate Recovery: Unlike their smaller counterparts, medium agencies did not experience a dramatic growth spike during the recovery, instead returning to their familiar pattern of steady, single-digit to low-double-digit growth.
This indicates that medium-sized agencies are built for resilience and predictability. Their value proposition often lies in consistent performance rather than rapid expansion.
What This Means for Your Agency’s Strategy
Understanding these historical trends is essential for contextualizing your own agency’s performance and preparing for a future transaction.
Implications for Sellers
When preparing to sell, the story behind your growth numbers is crucial.
- Frame Your Narrative: If you are a small agency owner, you can showcase your agility and high-growth potential by highlighting how you capitalized on favorable market conditions. If you own a medium-sized agency, your narrative should emphasize stability, predictability, and the resilience of your client base and revenue streams.
- Benchmark Your Performance: Contextualize your growth rates against these industry averages. If your agency outperformed the average during a downturn or grew faster than peers during a recovery, this becomes a powerful selling point that demonstrates superior management.
- Explain the Dips: Be prepared to discuss any periods of low or no growth in the context of broader economic events. Showing that you successfully navigated a recession is a testament to your agency’s strength.
Implications for Buyers
For buyers, these trends help in evaluating potential acquisition targets.
- Assess Sustainability: When looking at a small agency with a history of high growth, perform due diligence to determine if that growth is sustainable. Was it the result of a temporary market wave, or is it built on a solid, repeatable strategy?
- Value Stability: Don’t overlook the power of predictability. A medium-sized agency with a long history of steady, moderate growth can be a lower-risk investment that provides a solid foundation for future expansion.
- Look for Resilience: An agency that successfully weathered the 2008-2011 downturn without losing significant ground is an incredibly valuable asset. Its ability to perform under pressure signals strong operational and management fundamentals.
Looking Forward
An agency’s growth rate is a reflection of its strategy, leadership, and the economic environment it operates in. By analyzing your performance against these historical benchmarks, you can build a more compelling narrative, set a more accurate valuation, and make more informed strategic decisions.
