Ask an agency owner what a carrier pays and you will hear one number: the base commission rate.

That number is real, and it is the least interesting thing about the contract.

Base commission is the part carriers compete on least and disclose most. What separates two agencies writing similar premium is sitting in the four other layers — the ones that never appear in a recruiting pitch because they depend on volume, loss ratio, and who signed the paper.

Here is the whole structure, layer by layer. It is the same five-layer structure OAA members are paid on, and the same one the rest of this site uses.1

Layer one: base commission

The share of written premium the carrier pays for placing the business. Rates differ by line, by class of business, and between new business and renewal.

What most owners miss: base commission is scheduled, not negotiated, for the overwhelming majority of independent agencies. If you are a 500-policy agency talking to a national carrier, the schedule you are offered is the schedule everyone your size is offered. You are not being singled out. You are being sorted by volume — which is the whole point of the layers below.

Layer two: profit sharing

Paid annually, based on two variables: how much premium you placed with the carrier, and how that book performed. Hit the volume threshold with a loss ratio under target and the carrier pays a percentage of premium on top of everything already earned. Miss the volume threshold by a dollar and you get nothing, no matter how clean the book is.

This is the layer that punishes small agencies hardest, and it punishes them twice. First, the threshold: a $900,000 book spread across seven carriers may not clear the minimum with any of them. Second, the math of small samples: one bad fire loss on a $250,000 book moves your loss ratio in a way the same loss on a $9M book does not. Good underwriting discipline gets erased by variance.

Scale fixes both problems — not because larger agencies are better underwriters, but because volume clears thresholds and dilutes single-claim variance.

Layer three: regional bonuses

Territory-level growth and retention incentives, negotiated on top of carrier compensation and paid on the business a region produces. Separate from profit sharing, and frequently misunderstood as the same thing: profit sharing pays on outcome — volume and loss ratio. Regional bonuses pay on behavior — new business production, retention above a stated floor, growth over prior year.

These are the most commonly left on the table, because they are the layer an agency has to plan around rather than simply earn. Two agencies with identical books can be paid very differently here based entirely on whether anyone read the addendum and built the year around hitting it.

For a standalone agency this layer usually does not exist at all. Regional incentive structures are negotiated for a territory, which means somebody has to be negotiating on behalf of one.

Layer four: SIAA Performance Marketing Support Fund bonuses

The first of the two layers that only exist inside a national alliance. The Performance Marketing Support Fund is an SIAA structure: bonus dollars tied to new business production, available to member agencies through the alliance and not otherwise reachable by an independent agency writing on its own paper.

The practical effect is that growth partly funds the marketing that produces it. That is a different operating posture from paying for lead generation out of margin and hoping the renewal year makes it back.

Layer five: SIAA national profitability bonuses

The top layer, and the one furthest out of reach alone. National profitability bonuses are paid on how the alliance’s entire book performs with a carrier — across every member agency, in every state.

No single agency, at any size an independent owner is likely to reach, produces enough premium to participate in results at that scale. This is the layer that is genuinely structural: you are either inside a network that clears it, or the money does not exist for you.

The asset underneath the layers

Not a layer, and not a payment — but the reason the layers matter.

Every policy you write is worth a multiple of its recurring revenue to a buyer — but only if you own it, and only if it can move. Ownership of expirations and portability of the book are contract terms, not assumptions. Captive agents learn this the hard way at retirement. Independent agents in poorly structured groups sometimes learn it the same way.

The question to answer before you sign anything: if I leave this relationship in year seven, whose customers are they, and which carrier appointments come with me? Get the answer in writing. An agency that owns its book with portable or direct appointments is worth a materially different multiple than one whose carrier access disappears at the exit door.

Why the layers compound

Owners tend to evaluate contracts one layer at a time, and usually only layer one. The layers are not independent.

Volume drives profit-sharing eligibility. Profit-sharing eligibility changes which carriers will write your appointment at all. Direct appointments change your base schedule. A better base schedule funds the producer who drives the growth that clears the bonus threshold. Every layer is an input to the next one.

Which is why an agency inside a network with real carrier leverage does not earn “a little more” than the same agency standing alone. It earns from five layers instead of one and a half.

What to do this quarter

You do not need a network to start. You need the documents.

  1. Pull every carrier agreement you have signed, including addenda. Most agencies cannot locate all of them. That is the first finding.
  2. Write down the profit-sharing threshold and current-year loss ratio for each carrier. If you cannot get the loss ratio from the portal, ask your marketing rep. They have it.
  3. Rank your carriers by total compensation per premium dollar, not by base rate. The list usually reorders. Sometimes dramatically.
  4. Identify the one carrier where a modest amount of additional premium would clear a threshold. That is your growth plan for the next two quarters, and it is worth more than a general instruction to “write more business.”
  5. Find the ownership and termination language. Read it twice.

Do that and you will know something most agency owners never find out: what your contracts are actually worth, and which of them are worth keeping.

Where OAA fits

OAA members keep their agencies, their books, and their names. What changes is the paper behind them: network-level contracts, network-level volume, and a share of the layers a standalone agency of the same size cannot reach on its own.2

We do not publish per-carrier or per-layer terms, and neither should anyone who has signed them. We do run the five-layer math with you on your own book, because the only honest version of this conversation is one run on your numbers.
