Why did my commission change? Diagnosing a commission amount that moved
Short answer. A commission amount moves for one of a short list of reasons: the rate changed, the policy moved from new business to renewal, the premium changed through an endorsement or renewal, the policy cancelled and commission was charged back, a premium audit added or returned premium, a split or override reallocated it, the statement netted several items into one figure, or the line was mapped to a different producer code. Work out first whether the rate or the premium moved, because that narrows the list. Then confirm the cause on the statement line before you raise it with the carrier.

Most of the time the statement already explains the change, spread across two or three lines.
TL;DR
- Split the change first: commission is premium times rate, so check which of the two moved, or whether the line is a reversal rather than a payment.
- Rate moved: a new schedule, or the policy crossed from new business to renewal.
- Premium moved: an endorsement, a renewal at a new premium, a cancellation and chargeback, or a premium audit.
- Neither moved: look for netting on the statement, a split or override, or a line booked under another producer code.
This guide is for the moment a commission figure on a carrier statement isn’t what you expected: lower, higher, split in two, or negative. It is a checklist of the usual causes and how to tell them apart from the statement. If the problem is a renewal that stopped arriving altogether, why carriers stop paying renewal commissions covers that case in depth; this guide doesn’t repeat it. Lapidar is a tool that checks commission statements line by line; it is in its founding pilot. The guide covers property and casualty business. Practice varies between carriers and states, and your agency agreement governs.
Did the rate change or the premium change?
Commission on a line is, in most cases, premium times rate. Before going through causes, divide the commission on the line by the premium on the line and compare it with what you expected:
- The rate is different and the premium is what you expected: start with the rate causes (a new schedule, new business vs renewal, a split).
- The rate is the same and the premium is different: start with the premium causes (endorsement, renewal premium, cancellation, audit).
- Both look right but the total for the policy moved: look at how the statement groups lines (netting) and whether part of it went to another producer code.
Some statements don’t show premium on every line. Then ask the carrier for the premium behind the line, or match it to the transaction in your agency management system.
What are the usual causes of a commission change?
| Cause | What moved | What it tends to look like |
|---|---|---|
| Rate schedule change | Rate | Same premium, lower or higher rate, from a date onward |
| New business to renewal | Rate | A lower rate from the first renewal term |
| Endorsement or premium change | Premium | An extra line, positive or negative, mid-term |
| Mid-term cancellation, chargeback | Premium | A negative line referring to the original policy |
| Premium audit | Premium | A line after the term ends, either sign |
| Split or override | Share | Less on your code, the rest on another code or a separate agreement |
| Statement netting | Presentation | One figure combining several transactions |
| Producer code mapping | Where it landed | The commission appears under a different code or not at all |
Did the carrier change the rate schedule?
If the rate is lower on every line for one line of business, state or program from a certain date, a new commission schedule is the first suspect; agency trade press has noted commission cuts among the pressures on agencies in hard coastal markets (IA Magazine, 2025). Check whether you received one, and which date it keys on: policy effective date, transaction date or statement date can give different rates for the same policy. When a carrier changes your commission rate walks through the transition month, endorsements on older terms and what to update on your side.
Did the policy move from new business to renewal?
Many schedules pay a different rate for the first term than for renewals. A policy that paid one rate last year and a lower one this year may simply have renewed. Check the schedule for separate new business and renewal rates, and check that the carrier treated the term correctly: a rewritten policy can come through as new business, and a renewal can be mislabelled. See new business vs renewal commission.
Did the premium change?
An endorsement that adds or removes coverage changes the premium, and the carrier pays or takes back commission on the difference, usually as a separate line. A renewal at a lower premium pays less commission at the same rate. Look for:
- an extra line on the same policy number, with its own transaction date;
- a renewal premium that differs from the expiring term;
- installment billing, where with some carriers commission arrives in parts as each installment is paid, so one month shows only a fraction.
Was the policy cancelled mid-term?
When a policy cancels before the end of the term, the carrier usually takes back the commission on the unearned premium as a chargeback; your agency agreement sets how much is returned. It can arrive months after the cancellation and can be netted against new commission, so a month’s total drops without an obvious negative line. Check the cancellation date, the method (pro rata or short rate) and the rate it was charged back at; commission chargebacks explained covers how to check one.
Was there a premium audit?
On auditable lines such as workers’ compensation and some general liability, the final premium is set after the term from audited exposure. Additional premium brings extra commission; return premium brings a chargeback. These lines often arrive long after the term and can be mistaken for errors. Commission on premium audits explains what to check.
Was the commission split or overridden?
If the policy is shared with another agency, an agency cluster or a managing general agent, part of the commission may be paid elsewhere or deducted before it reaches you. An override can also be paid separately from the base commission, on another statement. Inside your agency, a producer split changes what a producer is paid, but not what the carrier pays the agency; if a producer says “my commission changed”, check which of the two moved.
Is the statement netting several items into one figure?
Some statements show one commission figure per policy or per period that combines new premium, endorsements, chargebacks and adjustments. The total moved; no single item explains it. Ask for, or download, the transaction-level detail behind the figure. Agency bill statements may also net commission against premium you owe, which is a different question from whether the commission itself is right.
Was the line mapped to a different producer code?
If the carrier changed the agency or producer code on a policy, after a merger, a new sub-code or a data change, the commission may now land under another code or on a different statement. From your side, it looks like the commission shrank or disappeared. Check every statement and code you receive from that carrier before concluding the money is missing.
What does diagnosing one look like?
- Last year, new business, premium $3,000.00 at 15%
- $450.00
- This year, renewal, premium $3,200.00 at 12%
- $384.00
- Endorsement in month 4, −$400.00 at 12%
- −$48.00
- Commission this year so far
- $336.00
- Change against last year
- −$114.00
The rate check (384 ÷ 3,200 = 12%) shows the rate moved; the schedule explains it. The negative line explains the rest. Only if neither matches the schedule or the policy history is it a discrepancy worth raising.
When should you ask the carrier?
When you have ruled out the causes you can see and the figure still doesn’t match. Give the carrier the policy, the statement and line, the premium and rate you expected and why, the amount paid and the difference. Several items fit in one commission discrepancy letter. Keep the schedule and the carrier’s answer with your notes, so the same question doesn’t come back next year.
Where Lapidar fits
Lapidar is built to check each statement line against the premium and rate you expect for that policy, and to flag lines that don’t fit. Finding the cause and talking to the carrier stay with you; Lapidar won’t contact your carriers. It is in its founding pilot, it has no customers yet, and we’ll say so until that changes. If you’d like to try it, the founding pilot is open below.
Frequently asked questions
Why is my renewal commission lower than my new business commission?
Many commission schedules pay a lower rate on renewals than on the first term. Check your schedule for separate new business and renewal rates. If the rate paid on the renewal is lower than the renewal rate in your schedule, raise it with the carrier.
Why is there a negative commission on my statement?
A negative line is usually a chargeback: commission taken back because of a cancellation, an endorsement that reduced the premium, or a premium audit that returned premium. Match it to the original policy and check its date, premium and rate.
My commission dropped but the rate is the same. What changed?
If the rate is the same, the premium changed, or the statement is presenting it differently. Look for an endorsement, a lower renewal premium, installment billing, a chargeback netted into the total, or part of the commission landing under another producer code.
