Every owner retires exactly once. The multiple is set by the years before that day.

If you own an insurance agency, your book of business is probably your largest asset, ahead of your house and well ahead of anything in a brokerage account. Which raises the question most owners avoid until it is too late to fix anything: what is it actually worth, and what is quietly changing the number

This guide covers how books are valued, what buyers pay premiums for, what they discount, and what you can check in your own agency management system this week to know where you stand.

How a book of business is valued

Books sell as a multiple of either gross commission or EBITDA. The two methods answer different questions, and buyers pick the one that favors them unless you push back.

The multiple is not a mark of honor. It is a price for expected persistence: how much of the revenue the buyer believes will still be there in two years.

What quietly destroys the value

The destroyers are quieter than the builders, and they compound for years before anyone totals them:

Most owners find out what the book was worth the day they try to sell it, which is the day it is too late to fix any of this. The fix window is the two or three years before.

What to check in your own AMS this week

You do not need a valuation firm to know where you stand. Five queries in your own system:

That list is a self-diagnosis. If you can pull it in an afternoon, your data is better than most. If each item is a project, the data itself is the first finding.

How we fit into this

We build and run the systems that work the destroyers: the renewal outreach that starts before the rate letter lands, the cross-sell work that turns one-policy households into three-policy ones, the data hygiene that keeps the book provable. It starts with the numbers, not the build: a fixed-fee look at your own book, ranked and priced, before anyone commits to anything.

Frequently asked questions

How much is an insurance book of business worth? +

Mostly between 1.5 and 3.5 times annual commission, depending on the mix. Personal lines books sit at the lower end, commercial at the higher end, with the best-run agencies commanding more. Larger agencies are usually valued as a multiple of EBITDA instead, commonly 4 to 6 times.

What is the rule of thumb for valuing a book of business? +

Two to three times commission is the working shorthand for a healthy commercial book. But rules of thumb ignore retention, concentration, and data quality, which is exactly where real offers move. Treat the shorthand as a floor for conversation, not a number to plan a retirement around.

Do you pay taxes on the sale of a book of business? +

Usually, and the structure decides how much. Asset sales generally allocate the price across tangible and intangible assets taxed at capital gains rates for the seller, while stock sales, where available, have their own treatment. This is accountant territory: have one involved before you sign anything.

What multiple does a personal lines book sell for? +

Commonly 1.5 to 2.5 times annual commission. Personal lines books churn faster, are easier for clients to move, and depend heavily on service quality, so buyers pay less per dollar of commission than for commercial. Strong retention records and clean data move a personal lines book toward the top of that range.

How do I prepare my book of business for sale? +

Start two to three years out. Lift retention, capture the cross-sell you already own, diversify the top of the client list, clean the AMS records, and move client relationships off your personal phone and onto the firm. The preparation is the same work a well-run book does anyway, done on purpose.
