Agency value is not produced by a single number. Two agencies of identical Normalized EBITDA can clear the market at enterprise values fifty percent apart, and the gap between them is not luck. It is the buyer's judgment on twenty different signals, weighted by twenty years of empirical research, then compressed into a single number called the Multiplier. The seller who understands which signals the buyer is reading — and which signals they are reading most heavily — can move their own number through the bands in ways that no negotiating tactic can.
This Pillar is a map of those signals. It is grounded in the National Alliance Research Academy's 38-factor study — the most comprehensive empirical ranking of value drivers in independent insurance agencies, refreshed three times across two decades — and it organizes the work into the Four Pillars of Premium Valuation that the institutional buyer's deal team will silently grade the seller against. If you take one thing away, let it be this: the Multiplier is not negotiated into existence; it is earned, one driver at a time, in the years before a buyer is ever in the room.
§ 01 · The 38-factor researchWhat the data has said for twenty years.
In 1993, 2001, and 2013, the National Alliance Research Academy surveyed thousands of agency owners on which operational factors most affect agency value. The 2013 third edition — drawn from 6,950 surveyed owners and 208 detailed respondents — produced a ranked list of 38 factors and a consistent finding across all three editions: the top three factors do not change.
The #1 factor, with a mean score of 4.84 on a 5-point scale, is Account Retention. The #2 factor is Quality of Personnel. The #3 factor is Customer Service. Together, these three form what the buyer's diligence team treats as the value foundation: client stickiness, human capital, and service delivery. A book strong on these three is a book the buyer will pay a premium for. A book weak on any of the three is a book whose multiple will compress, regardless of how high the headline EBITDA looks.
Below the top three, the factors fan out into four clusters that organize the rest of the work — financial performance, operational scale, market position, and intangible capital. Factors scored 4.0 or higher are flagged as critical and require remediation before listing. Factors scored 3.0 to 3.99 are important for ongoing management. The 38-factor framework is not a checklist of optional improvements; it is a diagnostic of which work has the most leverage on the multiple.
Twenty years of empirical research arrive at the same answer every time: the buyer pays the most for retention. The seller who treats retention as a chart on a dashboard pays the price. The seller who treats it as the central operating metric of the agency earns the Multiplier the chart implies.
§ 02 · The MultiplierA quality score, not a negotiation.
The market values an agency with a single equation and three inputs. Two of them have already been covered in detail in the agency valuation methods Pillar; the third is what this entire the critical factors of agency value Pillar is about.
Enterprise Value = Normalized EBITDA × Multiplier
Where Multiplier is the buyer's quality-adjusted ratio that captures the stability, sustainability, and growth profile of the agency's earnings. The Multiplier is not a single number across the market; it is a band, and the seller's work is to land in the upper half of the band for an agency of their size and book type.
The Multiplier organizes around Four Pillars of Premium Valuation. Each pillar contains a subset of the 38 factors, and each pillar is graded independently by a sophisticated buyer's diligence team. A book that scores high on three pillars and low on one will still clear the market band; a book weak on two or more will compress to the floor of its band, regardless of headline EBITDA.
- Financial Quality & Resilience. Normalized EBITDA, three-year earnings trend, margin profile, revenue diversification, contingent-income mix, and the credibility of the financial recasting itself. The seller's books are the primary evidence; the Quality of Earnings report is the validation.
- Operational Strength & Scalability. Owner dependency, documented standard operating procedures, AMS data integrity, producer compensation structure, revenue per employee, and the agency's demonstrated ability to operate at scale without the founder's daily involvement.
- Strategic Market Position. Carrier appointments, MGA relationships, niche concentration, geographic moat, line-of-business mix, and the agency's position relative to a regional or national consolidation thesis.
- Intangible Capital & Assets. Brand equity, producer non-piracy and non-compete coverage, key-employee retention contracts, perpetuation plan, E&O claims history, and the cleanliness of the corporate and ownership architecture.
The seller who walks into a buyer conversation knowing which of the Four Pillars their book is strongest on — and which they are weakest on — controls the framing of the negotiation. The seller who does not is anchoring on the buyer's framing, and the buyer's framing always emphasizes the pillar where the seller is weakest.
§ 03 · RetentionThe golden metric, in numbers.
Account Retention sits at the top of every empirical ranking for a reason: it is the single most predictive proxy for the future cash flow a buyer is acquiring. A book with 96% account-level retention is, in the buyer's underwriting, an annuity. A book with 85% retention is a wasting asset whose value erodes at compound speed.
The numbers behind this are unsentimental. At 96% account retention, the buyer's five-year revenue projection is 81.5% of year-one revenue. At 90%, it is 59%. At 85%, it is 44%. The Multiplier compresses to match. An agency at 96% retention can clear an 8× to 10× band; the same agency at 85% retention clears 5× to 7× — a delta of three turns of the multiple that the seller created or destroyed through the operating discipline of the past three years.
| Account retention | Multiple band |
|---|---|
| Below 85% (declining book) | 4× – 5× |
| 85% – 89% (market median) | 5× – 7× |
| 90% – 92% (above median) | 7× – 8× |
| 93% – 95% (market band — prepared) | 8× – 10× |
| 96%+ (competitive band — premium) | 10× – 12× |
| 96%+ with platform fit (kill-zone) | 12× – 19× |
Two practical points follow from this. The first is that retention has to be measured at the account level, not the revenue level. Revenue retention is inflated by rate increases on the renewing book; account retention is not. Buyers will normalize to account retention themselves; a seller who quotes a 97% revenue retention number on an 88% account retention book is going to lose credibility before the second conversation.
The second point is that retention has a documentation requirement. A retention number that exists only in the agency owner's head is worth nothing to a buyer. A retention number with three trailing years of policy-count and account-count history pulled from the AMS, broken down by line of business and producer book, is worth the premium it implies. The Strategic Runway is when an owner builds that documentation; the diligence period is when a buyer will demand it.
§ 04 · Personnel & owner dependencyThe #2 driver and the #1 discount.
Quality of Personnel is the #2 factor in the empirical ranking, and the working definition is more concrete than the phrase suggests. A buyer's diligence team will probe four sub-questions: producer book ownership and tenure, account manager experience and credentials (CIC, CPCU, ARM), staff turnover trends, and the depth of any management layer between the owner and the front-line work. The book whose three top producers have ten-plus years of tenure and whose AMs hold mid-career designations clears a multiple band above the book that is two years away from its #1 producer's retirement.
The mirror image of the Quality of Personnel driver is Owner Dependency — the single most material discount in the 38-factor framework. High owner dependency triggers a 10% to 25% reduction in enterprise value, applied against the otherwise-supported Multiplier. The buyer's working diagnostic is the Vacation Test: can the agency operate at full revenue for thirty consecutive days without the owner's direct involvement? Most agencies cannot, and the buyer prices the failure in.
Closing the Owner Dependency discount is the highest-leverage operational work an agency owner can do in the years before a sale. It has four components: a management layer between the owner and the front line; documented SOPs for every revenue-producing function; a producer compensation structure that retains producers without the owner's personal relationships; and clean AMS data that allows another operator to read the book without a translator. None of the four is glamorous. Each of the four moves the Multiplier.
Owner Dependency is the biggest self-inflicted discount in the 38-factor framework. It is also the most fixable, given a Strategic Runway. Most owners do not fix it because the work feels personal — and they pay the discount precisely because of that.
§ 05 · Growth qualitySignal vs. noise.
Top-line revenue growth looks the same on a spreadsheet whether it came from new client acquisition or from carrier-driven rate increases on the renewing book. To a sophisticated buyer, those two sources of growth are valued very differently — and the seller who does not disaggregate them in their own books invites the buyer to do it for them, almost always to the seller's disadvantage.
Organic growth — growth from new clients, new lines of business, or new producer hires — is the growth the market pays the full Multiplier for. It is evidence that the agency's go-to-market actually functions and that the next five years of revenue will look bigger than the last five. A book with a defensible three-year organic growth rate in the 6% to 10% band clears the upper half of any size-tier multiple band; a book in the 10%-plus band, sustained over three years, frequently clears into the competitive band entirely.
Inflationary growth — growth from rate increases imposed by carriers on the existing book — looks the same in revenue but signals the opposite. It is passive. It will end when the rate cycle ends. Buyers strip it out of the growth rate to assess organic performance, and a seller who does not pre-strip it themselves is going to watch the buyer do it more aggressively. A book that grew 12% revenue but only 1.5% in policy count and account count is, for the buyer, a book that didn't really grow at all.
The discipline is straightforward: every quarterly report a prepared seller produces should separate "organic policy count growth" from "renewal-rate effect on existing accounts" from "new lines or producers." Each becomes a line in the diligence packet, and the buyer's risk-adjustment moves to match the share of total growth that is actually organic.
§ 06 · Carrier mix and concentrationThe market-access foundation.
An agency's carrier mix is the foundation of its market access — and a structural source of either premium or compression depending on how it is constructed. Three sub-drivers move the Multiplier here: carrier concentration risk, MGA relationships, and the underlying commission economics across the book.
The first sub-driver is carrier concentration. A book with more than 40% of revenue from a single carrier is, in the buyer's underwriting, a book one cancellation away from a structural revenue cliff. Sophisticated buyers compress the Multiplier by a half-turn or more for books at 40%-plus concentration; books above 60% may not be acquirable by an aggregator at all without an explicit pre-close carrier appointment transfer. The Strategic Runway is when an owner deliberately balances the book — moving accounts across carriers, building secondary appointments — to bring concentration below the buyer's compression threshold.
The second sub-driver is MGA relationships. Wholesalers and MGAs are increasingly the only access path for specialty E&S lines, hard-to-place commercial accounts, and emerging risk categories. A book with documented, defensible MGA relationships — particularly relationships that the seller's producers can transfer to a buyer — earns a multiple premium because it represents incremental market access the buyer cannot replicate by acquisition alone. The premium is concrete: a seller's MGA book frequently clears at a multiple a turn above the seller's underlying agency multiple, because the buyer is paying for capability not just cash flow.
The third sub-driver is commission economics. The buyer's diligence team will run a line-by-line analysis of the commission rate on each major appointment, comparing the seller's rates against the buyer's existing platform. Where the seller's rates are above the platform, the buyer captures the uplift and pays the seller for it. Where the seller's rates are below, the buyer takes the gap as risk and compresses the Multiplier accordingly. The owner who renegotiates two or three under-market commission rates in the year before a sale typically recovers more in multiple uplift than the cost of the renegotiation itself.
§ 07 · The driver scorecardEight signals to grade your book.
The 38-factor research is exhaustive; a working seller's diagnostic does not need to be. Eight drivers concentrate the empirical weight of the framework into a checklist a prepared owner can grade their own book against in an afternoon. Every "yes" is a half-turn closer to the upper band; every "no" is the work that has to happen before a credible listing.
- Account-level retention above 92% for three trailing years. Measured at the account, not the revenue. Documented from the AMS, broken down by line and producer.
- Quality of Personnel — at least two senior producers with five-plus years of tenure and at least one mid-career-designation AM. Producer non-piracy and non-compete coverage current within twelve months.
- Vacation Test passed. Thirty consecutive days at full revenue with the owner uninvolved. Documented evidence, not assertion.
- Three-year organic growth rate above 5%, with rate effect explicitly stripped out. Policy count and account count rising independently of carrier rate increases.
- Carrier concentration below 40% on the largest single carrier. Secondary appointments alive on every major line. MGA relationships documented and transferable.
- Commission rates at or above platform benchmarks. Where the rates are below, a documented plan to renegotiate before listing.
- Normalized EBITDA margin at or above tier median. Three-year trend stable or rising. Add-back stack defensible without a QoE.
- Owner Dependency closed. A management layer between owner and front-line work. Documented SOPs. Clean AMS. Producer compensation structure independent of the owner's relationships.
An owner who can answer "yes" to seven or eight of these is anchoring in the competitive band of their tier's multiple range. An owner at five or six is anchoring in the market band. Below five, the seller is anchoring in the band where the buyer's offer is going to be the floor — the band where the Silent Discount lives.
The Multiplier is not a number a buyer assigns. It is a number a buyer discovers in the operating record of the agency. The seller's work, in the years before a sale, is to make the discovery favorable.
The work of grading these drivers is also the work of remediating them. The 38-factor research is read most usefully not as a postmortem of agencies that already sold, but as a forward-looking diagnostic of where the next three years of operating attention should go. Every driver an owner moves before listing is a driver they cannot move once a buyer is in the room. The competitive band is reserved for owners who do this work in advance; the market band is for owners who arrive at the conversation with most of it still in front of them.
The Four Pillars of Premium Valuation are not aspirational. They are the empirical structure the institutional buyer's investment committee uses to defend or compress every offer. A seller who learns to grade their own book through those four pillars stops being surprised by the buyer's number — because they have already arrived at the same number, from the same evidence, before the first call.
Your next chapter starts with one diagnostic. The same eight drivers a buyer's deal team will silently grade your book against, run honestly against your own book first. Milly Books delivers an objective, data-driven valuation of your book of business — anchored to actual market transactions and the same 38-factor framework professional buyers use.
The self-diagnostic checklist — grade your own book before the buyer does:
- Score the book against the Four Pillars of Premium Valuation the way an investment committee will.
- Find your weakest of the eight drivers — that is where the buyer will compress the offer.
- Quantify the retention, growth, and concentration metrics that move the multiple most.
- Address the fixable factors during the Strategic Runway, before going to market.
- Arrive at the buyer's number first, from the same evidence — so the offer never surprises you.
