Insurance agency profit sharing: how contingent commissions are calculated, and how to check yours

TL;DR

• Profit sharing and contingent commission usually name the same thing: a yearly carrier payment based on how your whole book with that carrier performed against a separate agreement.
• The carrier works it out from its own data, typically earned premium and incurred losses, including reserves on claims still open. Neither appears on your monthly commission statements.
• Most gaps between the carrier’s figure and yours come from scope: which agency codes were counted, which lines were left out, and where business placed through a network or moved between codes ended up.
• You can only check the payment if you kept your side of the numbers during the year and ask for the worksheet. Even then, a difference is a question for the carrier, not proof of money owed.

We’re building Lapidar, software meant to check monthly carrier commission statements. It isn’t ready yet, and it won’t calculate contingent commissions. This guide explains how the annual figure is usually put together and where it goes wrong, so you can read the next one with your own numbers beside it.

Much of what’s published on profit sharing is about earning more of it: which targets to chase, which carriers to concentrate on, how to reach a better tier. This guide covers the narrower job that comes after: checking the number you were actually paid.

What profit sharing is, and when it arrives

A contingent commission is paid on top of the ordinary commission on each policy. It depends on how the agency’s entire book with one carrier performed over a period, against targets set in a profit-sharing agreement or an addendum. It also goes by contingency bonus or contingent compensation, and some carriers run a separate growth bonus beside it.

The measurement period is usually a year, often the calendar year, though the agreement sets it. According to MarshBerry, these payouts are typically worked out once a year and paid in the spring after the year they cover. So the money lands months after the year has closed, usually as one statement line or a separate payment, tied to no particular policy.

It can be a large share of an agency’s income. MarshBerry puts contingent commissions at about 5%–7% of total annual revenue for many agencies, and as much as 10%–15% for some top-performing firms in some years. A 2025 article in IA Magazine gives 10%–20% or more of annual revenue in good years, and stresses that the income is unpredictable. Those are published ranges, not a benchmark for your agency, but they explain why one mistake on the worksheet can outweigh a year of small statement errors.

What usually drives the calculation

Every carrier writes its own formula, and one carrier can have several. The building blocks, in general terms, are these:

• Minimum premium volume. Below a set amount of eligible premium, nothing is paid, whatever the results.
• Loss ratio. Incurred losses divided by earned premium, for the year or sometimes averaged over several years. MarshBerry describes it as often a major factor in these programs.
• Growth. The change in premium against the prior year. It can be a condition for any payment at all, or a factor that raises the rate.
• Retention. The share of business that renewed. MarshBerry notes that retention and product-mix targets often work as qualifiers or multipliers.
• The grid. A table, often crossing loss ratio with growth or volume, that gives a percentage to apply to eligible premium. Because it is tiered, a small change near a boundary can move the whole payment up or down a level.
• Addendums and options. In a 2004 article republished by the Big “I” Virtual University, consultant Chris Burand warned that a carrier with nominally one contract can attach very different addendums to it, and that those addendums can change the outcome a great deal. Agreements may also offer choices, such as a stop-loss level, which usually limits how much of any single large claim counts against you.

So the first document to find isn’t a report. It’s the agreement and every addendum in force for the year being paid. Burand’s blunt observation, back in 2004, was that most agency owners never read their contracts.

Why the carrier’s figure and yours differ

Laid beside your own records, the carrier’s worksheet rarely agrees with them. Much of the gap has ordinary causes, and each has to be ruled out before anything is worth raising:

• Earned, not written, premium. Your monthly statements usually show written premium transaction by transaction, or premium as collected on pay-as-collected business. Many agreements measure the loss ratio on earned premium, the part that corresponds to coverage already provided. A policy written in December adds its full premium to your written total and almost nothing to earned. Some grids use written premium for growth and earned premium for the loss ratio, so one worksheet can mix both.
• Incurred losses include open reserves. The carrier’s incurred losses are normally what it has paid plus the reserve it set on each claim still open at the valuation date. You don’t set those reserves, and you may not see them claim by claim. One large open claim can push the loss ratio across a tier.
• Which codes roll up. An agency can hold several codes with one carrier: one per location, one from a book it bought, sub-codes for individual producers. The agreement says which of them count together. A code left out removes its premium and its losses, so the effect can go either way.
• Excluded lines or programs. Agreements often leave out particular lines, programs or products, or treat them under separate terms. Premium that looks eligible in your system may not be in the carrier’s base at all.
• Policies moved between codes. When policies change code mid-year, through a consolidation or an agent-of-record change, the premium and the loss history don’t always move together.
• Business placed through a network. If you write some of a carrier’s business through an aggregator or network, that volume usually counts toward the network’s agreement rather than yours, and what comes back to you depends on the network contract.

What to keep through the year

The worksheet arrives once. Your side of it has to be built during the year, while the details can still be recovered:

• Written premium by carrier and by agency code, month by month, taken from the carrier’s own commission statements rather than only from your management system, because the statements show what the carrier recorded. Keep new business, renewals, endorsements and cancellations visible instead of netting them.
• The carrier’s production and loss reports for each of your codes, saved each time they arrive, not just the latest one. Depending on the carrier, they show written and earned premium, incurred losses and the loss ratio for the year to date, and they are usually the only regular source of earned premium you’ll see before the worksheet. Keep the two bases apart: written premium from the statements, earned premium from these reports. A reserve that rose and later fell only shows up if you kept the earlier reports.
• Retention, as the agreement defines it: by policy count, by premium, or some other way. Your own definition doesn’t help if the carrier measures something else.
• The agreement, every addendum and the grid for that year, plus a dated note of every code change, book purchase or transfer.

Each item is ordinary. Keeping all of them, for every carrier with an agreement, for twelve months before anyone asks, is where it usually breaks down.

Ask for the worksheet, and read it line by line

A contingent payment without its calculation can’t be checked. Ask the carrier for the worksheet behind the figure: the codes included, eligible premium (written and earned, as the agreement uses them), prior-year premium for growth, paid losses and reserves, the loss ratio, any stop-loss or large-loss adjustment, the tier reached and the rate applied. Ask for it in years when you were paid nothing, too.

Then put your own figure next to each line and find where the inputs differ, and why. Earned premium and losses on your side come from the production and loss reports you kept, code by code, not from the written premium on your statements. Running the grid on your own figures only shows which differences are big enough to matter; it doesn’t give the amount you’re owed.

Two lines explain the whole gap here, and they lead to different conversations. The missing code, EX-100-B, is a question of scope: if the agreement says it rolls up, its $85,000 of earned premium and its $14,000 of losses belong in the calculation. Adding it alone gives a loss ratio of 47.7%, still in the 1.0% tier, and a payment of $12,650.

The large claim, part of the incurred losses on both sides, is what moves the tier, and it is the weaker case. The worksheet counted its $110,000 reserve on the valuation date; it later closed at $32,000. Whether the carrier revisits the year for that depends entirely on the agreement, and some settle each year as of the valuation date and never reopen it. A difference on a worksheet is a question to raise, with your evidence attached. It isn’t money owed until the agreement says so.

Where errors hide

• Missing sub-codes. A code opened during the year for a new location or producer, and never linked to the master code the agreement measures.
• A book acquired mid-year. Its premium may count from the transfer date, from the start of the year, or not until next year. If the prior-year base and the current year treat it differently, growth is distorted in one direction or the other.
• Transferred policies. Policies moved in or out during the year can be counted twice or not at all, and their losses may stay behind.
• Large losses later closed lower. As in the example above. Where the agreement uses a loss ratio averaged over several years, the same claim can affect more than one payment, valued differently each time.
• Thresholds nobody noticed. Burand pointed out that contracts carry thresholds that are obvious and others that are hidden, and that the handling of claim reserves and closed claims affects the bonus. A condition buried in an addendum can decide the year on its own.

Why it matters beyond this year’s payment

Profit sharing also comes up when an agency is valued or sold. The 2025 IA Magazine article, by Keith J. Mangini of InsurBanc, describes sellers presenting a steady record of contingent income as evidence of sound underwriting and good retention, and buyers welcoming that record but treating it with caution. It singles out transferability: whether the agency’s appointments with carriers, and the profit-sharing agreements that come with them, pass to a buyer at all. What that means for a buyer’s due diligence is in buying an insurance book of business. Lenders, it adds, don’t treat the income as the main way a loan gets repaid, although a run of consistent years is taken as evidence of solid relationships with carriers.

MarshBerry makes a related point: contingent income that holds up over time and is spread across carriers can raise what an agency is worth and how interested buyers are.

The record is only as strong as its evidence. Years of worksheets checked against your own book of business, with differences raised and resolved, say more than a column of deposits.

Why this is hard at scale

Profit sharing is a once-a-year calculation on data you only partly see. The losses and reserves are the carrier’s. Earned premium doesn’t appear on your statements, only in the carrier’s own reports. Every carrier writes its own formula, and the addendums change it. By the time the worksheet arrives, the year closed months ago, and the checking is done from old files and memory.

The part you do control, your own record of written premium by carrier and code, is itself built from twelve months of statements per carrier, each in its own layout, many of them PDFs, with policy numbers that don’t match your system. If those monthly statements were never reconciled, the figure you set against the worksheet carries the same gaps. We go through that monthly work in what to check when reconciling carrier commission statements. Then multiply all of it by every carrier you have an agreement with.

Where Lapidar fits

To be plain about it: Lapidar does not calculate contingent commissions, and it won’t check a carrier’s losses or reserves. Those come from the carrier, under each agreement. What we’re building it to do is the monthly work underneath: check each carrier commission statement line by line against your book, and flag commissions that are missing, underpaid or paid twice. Once that check runs every month in the Lapidar web app, it will leave you a checked record of statement premium, carrier by carrier, to have in front of you when the worksheet arrives. It’s in development, it isn’t live, and it has no customers yet. What a full check of past commission statements covers is set out on our commission audit page.

Frequently asked questions

Is profit sharing the same as a contingent commission?

In everyday use, yes. Profit sharing, contingent commission and contingency bonus usually name the same thing: a payment on top of ordinary commission, based on how the agency’s whole book with one carrier performed against a separate agreement. Some carriers split it into more than one program, for example a profit-based payment and a growth bonus, each with its own rules, so read each agreement on its own terms.

Do producers get a share of profit sharing?

It depends on the agreement. Some agencies pass part of the contingent payment to producers, many keep it at agency level, and some producer agreements exclude it in so many words. Because the payment is calculated on the whole book with a carrier, not policy by policy, any share needs its own rule. Your producer agreements decide it. How agencies write those rules is covered in producer commission splits.

We didn’t qualify this year. What should we check?

Ask for the worksheet even when the answer is zero. Then check which agency codes were counted, whether the minimum volume was measured on written or earned premium, whether one large open reserve pushed the loss ratio over a threshold, whether business placed through a network counted toward someone else’s agreement, and whether a book bought or moved during the year changed the base. Not qualifying can be entirely correct. The point is to know why.
