You can value an insurance book of business in three ways: a revenue multiple (typically 1.5x to 3x annual commissions), an EBITDA multiple (6x to 12x), or a discounted cash flow (DCF) calculation. Most small books sell on the revenue multiple, while larger agencies command EBITDA-based valuations.
In this guide, you’ll learn:
- The three valuation methods buyers and sellers actually use
- Current 2026 multiples and where your book likely falls
- The 8 factors that push your valuation up or drag it down
- A worked example showing each method side by side
- Common mistakes that cost sellers tens of thousands
Here’s the step-by-step process you can follow whether you’re buying, selling, or planning your exit.
What Is an Insurance Book of Business?
An insurance book of business is the complete portfolio of policies, clients, and renewal commissions controlled by an agent or agency. It includes active policy data, carrier appointments, expiration dates, premium volumes, and the relationships that generate recurring revenue. When you buy or sell a book, you’re paying for that future stream of commissions, not just a customer list.
Books are bought and sold constantly. An agent retiring sells their book to a successor. A captive agent moves to independent and sells their old book back to the carrier. A growing agency rolls up smaller producers. Each transaction needs a defensible valuation, and the methods below are the industry standards.
Method 1: Revenue Multiple (The Quick Method)
The revenue multiple is the fastest way to value a book. You take the annual gross commissions the book generated last year, then multiply by an industry multiple — typically 1.5x to 3.0x for personal lines and small commercial books.
Formula: Annual Commissions x Multiple = Book Value
So a personal lines book generating $200,000 in annual commissions at a 2.0x multiple is worth roughly $400,000.
The multiple you use depends on the book’s quality. According to Peak Business Valuation, most insurance books trade between 1.5x and 2.5x trailing twelve-month commissions. Premium books with 90%+ retention and stable carrier appointments hit the high end. Books with churn issues or single-carrier dependence sell at the low end.
When to use the revenue multiple
This method works best for small books (under $500K in annual commissions), straightforward personal lines portfolios, and quick napkin-math negotiations between two agents. It’s the dominant method for owner-to-owner sales because it’s simple and the data is easy to verify.
Method 2: EBITDA Multiple (The Standard for Agencies)
For full insurance agencies — not just standalone books — buyers and sellers prefer the EBITDA multiple method. EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It represents the true operating profit of the business.
Formula: EBITDA x Multiple = Agency Value
Current 2026 multiples typically run 6x to 12x EBITDA. Smaller agencies (under $1M in revenue) usually transact at 6x to 8x. Mid-sized agencies hit 8x to 10x. Larger platforms with 20%+ EBITDA margins and strong organic growth can reach 10x to 12x or higher when private equity buyers are involved.
Sica Fletcher’s market data shows the average insurance agency now sells at 8x to 12x EBITDA, up sharply from a decade ago when 5x to 7x was standard. PE consolidation has bid up multiples across the sector.
Calculating EBITDA correctly
You start with net income, then add back interest expense, taxes, depreciation, and amortization. For owner-operated agencies, you also add back excess owner compensation — anything paid to the owner above what you’d pay a hired manager. This is called adjusted EBITDA or seller’s discretionary earnings, and it’s what most buyers will base their offer on.
If your agency reports $150,000 in net income, $20,000 in interest, $10,000 in taxes, $15,000 in depreciation, and the owner takes a $200,000 salary when a hired GM would cost $100,000, your adjusted EBITDA is $295,000. At a 7x multiple, that’s a $2.06 million valuation.
Method 3: Discounted Cash Flow (The Most Rigorous)
The discounted cash flow (DCF) method is the most thorough valuation approach. You project the book’s future cash flows (typically 5 to 10 years), then discount them back to present value using a discount rate that reflects the risk of those cash flows.
Formula: Sum of (Future Cash Flow / (1 + Discount Rate)^Year) = Present Value
DCF is the standard method used by certified business appraisers, M&A advisors, and lenders financing acquisitions. According to the International Risk Management Institute, DCF gives the most accurate valuation because it accounts for retention rates, growth, and the time value of money.
When to use DCF
Use DCF when you need a defensible valuation for a court proceeding, divorce, partner buyout, SBA loan, or estate planning. It’s overkill for a $300K personal lines book changing hands between two agents, but essential for any deal above $1 million or any situation where you need a paper trail.
A simplified DCF for a book generating $200,000 annual commissions, growing 3% per year, with a 90% retention rate and a 12% discount rate, would value the book at roughly $1.4 million over a 10-year projection — substantially higher than the revenue multiple method would suggest.
Quick Comparison: Which Method to Use
| Method | Best For | Typical Range | Effort |
|---|---|---|---|
| Revenue Multiple | Small books, quick deals | 1.5x to 3.0x commissions | Low |
| EBITDA Multiple | Full agencies, standard sales | 6x to 12x EBITDA | Medium |
| DCF | Large deals, legal/tax matters | Varies | High |
Most real-world transactions use a blend. A buyer might run all three methods, then negotiate within the range each one produces.
The 8 Factors That Move Your Valuation
Two books with identical revenue can be worth wildly different amounts. Here are the factors that drive the multiple up or down, ranked roughly by impact.
1. Retention Rate
Retention is the percentage of clients who renew year over year. According to Agency Performance Partners, the industry average sits around 84%, while top-performing agencies hit 96%+. Every percentage point of retention above 90% adds measurably to your multiple. Buyers pay a premium for predictability, and a 95% retention book is worth dramatically more than an 80% retention book of the same size.
2. Carrier Mix
Books concentrated with one carrier carry single-carrier risk. If that carrier exits the market, raises rates, or terminates the appointment, the entire book can collapse. Books with 5+ active carrier appointments sell at higher multiples because they’re more resilient.
3. Line of Business
Personal lines (auto, home) generate steady, predictable commissions and trade at 1.5x to 2.5x revenue. Commercial lines books — especially specialty commercial like cyber, professional liability, or trucking — trade at 2.0x to 3.5x because the policies are stickier and commission rates are higher. Life and health books are valued differently, often using a present-value-of-renewals model.
4. Geographic Concentration
A book concentrated in one zip code is more vulnerable to local economic shocks, natural disasters, or regulatory changes. Geographically diversified books command better multiples.
5. Average Account Size
Books with larger average premiums per account are more efficient to service and more profitable. A book with 200 commercial accounts averaging $5,000 in premium is more valuable than a book with 1,000 personal lines accounts averaging $1,000, even if total commissions are similar.
6. Client Demographics
Younger clients with longer expected policy lives boost valuation. A book heavy on retirees may produce strong current cash flow but face natural attrition, which buyers factor in.
7. Producer Dependence
If the book depends entirely on the seller’s personal relationships, the buyer faces transition risk. Books with strong CRM systems, documented processes, and multiple service staff transfer more smoothly and sell at higher multiples.
8. Growth Trajectory
A book growing at 8% annually is worth substantially more than a flat or declining book of the same size. Growth signals demand, sales capability, and future cash flow expansion.
Step-by-Step: How to Value Your Book
Follow this sequence whether you’re buying, selling, or just curious what your book is worth.
Step 1: Gather your financial data
You need three years of:
- Gross commission income by carrier
- Net commission income (after splits and fees)
- Operating expenses
- Owner compensation
- Policy count by line of business
- New business vs. renewal commission breakdown
Most agency management systems (Applied Epic, AMS360, EZLynx, HawkSoft) export these reports directly.
Step 2: Calculate your retention rate
Use this formula:
Policies in force at end of year / (Policies at start + new policies written) = Retention %
Calculate it for each of the past three years to show the trend. Buyers want to see the trajectory, not just last year’s number.
Step 3: Run all three valuation methods
Calculate the revenue multiple range, the EBITDA multiple range, and a basic DCF. The three numbers should fall within a similar range. If they don’t, dig into why — usually there’s an EBITDA adjustment or growth assumption that needs revisiting.
Step 4: Apply quality adjustments
Move within the range based on your specific factors. Strong retention, diverse carriers, and good growth push you to the high end. Concentration risk, declining revenue, or producer dependence push you to the low end.
Step 5: Get a second opinion
Before any transaction above $500K, hire a credentialed business appraiser or insurance M&A advisor. The fee — typically $5,000 to $15,000 — pays for itself many times over by surfacing value drivers you missed and giving you defensible numbers in negotiation. Firms like OPTIS Partners and MarshBerry specialize in insurance agency valuations.
Worked Example: A $250,000 Book of Business
Let’s value a real-world book with these characteristics:
- $250,000 in annual gross commissions
- 92% retention rate
- 4 carrier appointments (good diversification)
- Personal lines auto and home
- Growing 4% annually
- $75,000 in adjusted EBITDA
- Owner-operated, no other staff
Revenue multiple calculation
At the midpoint multiple of 2.0x for a quality personal lines book:
$250,000 x 2.0 = $500,000
The 92% retention and growth justify pushing toward the upper end. Reasonable range: $425,000 to $550,000.
EBITDA multiple calculation
At a 7x EBITDA multiple for a small book:
$75,000 x 7 = $525,000
Reasonable range: $450,000 to $600,000.
DCF approximation
Using a 10-year projection with 4% growth, 92% retention, and a 15% discount rate, the present value of expected cash flows comes out to roughly $510,000.
The verdict
All three methods cluster around $475,000 to $550,000. A defensible asking price would be $525,000, with room to negotiate down to $475,000 in a soft market.
Common Mistakes That Cost Sellers Money
Sellers leave money on the table all the time. Watch for these:
- Using gross commissions instead of net. If you split commissions with a sub-producer or pay carrier fees, your real revenue is lower than your gross. Buyers will catch this in due diligence.
- Ignoring EBITDA adjustments. Forgetting to add back excess owner compensation can knock 30%+ off your valuation. Document every adjustment.
- Not normalizing for one-time events. A spike in commissions from a single large account or a one-time bonus inflates the trailing twelve months and won’t repeat.
- Selling on the wrong method. A high-EBITDA agency selling on a revenue multiple leaves significant value on the table. Match the method to the book.
- Neglecting the data room. Buyers discount uncertainty. Clean policy data, organized financials, and documented processes earn higher offers. According to the Big “I” association, well-prepared agencies sell for 15-20% more than poorly prepared ones.
How Long Does an Insurance Book Sale Take?
A typical insurance book sale takes 4 to 9 months from listing to closing. The valuation phase takes 2 to 4 weeks. Marketing and finding a buyer takes 2 to 4 months. Due diligence runs 30 to 60 days. Closing and transition take another 30 to 90 days.
Larger agency sales involving SBA financing or earnouts can stretch to 12 months. Smaller owner-to-owner book sales sometimes close in 60 days when both parties already know each other.
Should You Use a Broker?
For books above $500,000, a specialized insurance agency broker is usually worth the 8% to 12% commission. Brokers maintain buyer networks, run competitive processes, and consistently get sellers 15% to 25% higher prices than direct sales. Below $250,000, the broker fee often eats the premium they generate, and direct sales make more sense.
FAQ
How do you calculate the value of an insurance book of business?
You calculate the value of an insurance book of business using one of three methods: a revenue multiple (1.5x to 3x annual commissions), an EBITDA multiple (6x to 12x), or discounted cash flow (DCF). Most small books sell on the revenue multiple. Larger agencies use EBITDA. DCF is reserved for legal proceedings and large transactions.
What is the average multiple for an insurance book of business?
The average multiple for an insurance book of business is 2.0x to 2.5x annual gross commissions for personal lines books, and 2.5x to 3.5x for commercial lines books. EBITDA-based valuations average 7x to 9x for small to mid-sized agencies, with larger platforms reaching 10x to 12x.
How much is a $1 million book of business worth?
A book generating $1 million in annual commissions is typically worth $1.5 million to $3 million using the revenue multiple method. The exact number depends on retention rate, carrier mix, line of business, and growth trajectory. A high-quality commercial lines book at this revenue level can exceed $3 million.
Can I sell my book of business if I’m a captive agent?
Most captive agents (State Farm, Allstate, Farmers) cannot sell their book of business externally. Instead, they receive a termination payment or enhancement payment from the carrier, calculated using a formula in their captive agreement. These payments typically range from 1x to 2x annual commissions but vary by carrier.
What’s the difference between book of business and goodwill?
The book of business is the tangible asset — policies, client data, and renewal commissions. Goodwill is the intangible value — brand reputation, processes, staff relationships, and growth potential. In small book sales, the entire price is allocated to the book. In agency sales, the price splits between tangible assets, the book, and goodwill, which has tax implications for both buyer and seller.
How does retention rate affect book value?
Retention rate has the biggest single impact on book value. A book with 95% retention sells for 20% to 30% more than a similar book with 80% retention, because buyers can count on more years of cash flow. Every percentage point of retention above 90% measurably raises the multiple a buyer will pay.
Final Thoughts
Valuing an insurance book of business comes down to picking the right method for your situation, gathering clean data, and understanding the factors that drive your specific multiple. Most sellers underestimate their book by skipping EBITDA adjustments or ignoring the value of high retention. Most buyers overestimate by missing concentration risk or poor data quality.
Run all three methods. Get a second opinion before any deal above $500,000. And remember that the best valuation in the world won’t help if your data room is a mess — buyers pay premiums for confidence and clean financials.
Whether you’re buying your first book, selling after 30 years, or planning a succession, the methods above are the same ones professional appraisers use. Apply them honestly, and you’ll arrive at a defensible number both sides can agree on.
