Personal lines vs commercial lines commissions: how they differ for an agency

Short answer. Personal lines (home, auto, renters, other coverage for individuals and households) usually come as many small, mostly direct bill policies, so commission arrives as many small lines that change mainly at renewal, on installments and on cancellations. Commercial lines (coverage for businesses) usually mean fewer, larger accounts with more endorsements, premium audits after the term and, more often, agency bill, so the commission on one policy can change several times after it was written. Rates, splits between new and renewal, and billing are set by each carrier’s agreement and schedule, not by the line itself.

A personal policy changes mostly at renewal. A commercial one can change every month of its term.

TL;DR

Personal lines: high volume, small premiums, mostly direct bill. The risk is a missing or wrong-rate line hidden among hundreds.
Commercial lines: fewer accounts, larger premiums, more endorsements and audits, more agency bill. The risk is a policy whose commission changes after you stopped looking.
New and renewal rates come from each carrier’s schedule. Check the rate on each policy, in both lines.
Premium audits are mostly a commercial issue, because premium on lines such as workers’ compensation is based on estimates trued up later.
Fees are not commission. Whether you may charge them is a state question.
We don’t publish typical commission rates for either line: we have no public source that applies across carriers.

This guide is for owners and account managers at US independent property and casualty (P&C) agencies who write both personal and commercial business and want to know why the two behave differently on commission statements. It is about how the commission arrives and what to check. How agency bill and direct bill work in general is in direct bill vs agency bill commissions; the arithmetic of audits and endorsements has its own guides, linked below. Your agency agreements and commission schedules decide the specifics.

What is the difference between personal lines and commercial lines?

Personal lines cover individuals and households: homeowners, renters, personal auto, umbrella and similar. Commercial lines cover businesses: commercial property, general liability, commercial auto, workers’ compensation, package policies and more. Regulators draw the line in their own documents; the California Department of Insurance, for example, lists dwelling fire, homeowners multiple peril and private passenger auto liability as personal lines, and commercial fire and commercial multiple peril as commercial lines in the definitions for a 2004 study (California Department of Insurance). For commission purposes what matters is what each carrier’s schedule calls the line, because that decides the rate.

How do new business and renewal commission differ between them?

Many carrier schedules set one rate for new business and another for renewals, and some set different rates by line, by product or by state. Neither line has a universal pattern we can source, so we don’t quote one. What differs in practice is where the checking effort goes:

Personal lines: most lines are renewals. A personal auto or home policy usually renews with little change, and the error to catch is a renewal paid at the new-business rate, the old rate after a schedule change, or not at all. See missing renewal commissions.
Commercial lines: a renewal is often re-quoted, re-rated or moved to another carrier, so it can look like new business on one statement and a renewal on another. Check which rate the carrier applied, and whether a rewritten policy was coded as new or renewal under your schedule.

Why do premium audits matter mostly for commercial lines?

Some commercial policies are priced on an estimate, such as payroll for workers’ compensation or sales or payroll for some general liability, and the carrier audits the actual figure, usually after the term. As Nancy Germond of the Big “I” put it in IA Magazine, “estimated payroll is just that, an estimate” (IA Magazine). The audit can produce additional or return premium months later, and commission follows it in either direction. Personal policies are rarely rated this way, so audits seldom touch personal lines commission. How to check audit commission, including what happens when the insured won’t pay it, is in commission on premium audits.

How do billing and installments differ?

The usual tendency, which our direct bill guide covers with its source, is that larger accounts lean toward agency bill and small personal policies toward direct bill (Insuranceopedia). The carrier and your agreement decide each policy.

Personal lines are mostly direct bill, often paid in installments. Depending on the carrier, commission may be paid on the full term premium up front or on each installment as it is collected. On a per-installment carrier, one policy produces a line every month, and a missed payment simply produces no line, which is easy to miss.
Commercial lines come both ways. On agency bill, you collect the premium, keep the commission and remit the net on the account current, so the commission is right only if the account current is right; see agency bill reconciliation. Larger commercial accounts are also more often premium financed, which changes who pays whom but not the commission rate.

Where do fees fit?

A policy fee charged by a carrier and a broker or service fee charged by your agency are not commission, and they shouldn’t be counted as commission when you check a statement. Whether an agency may charge a fee on top of commission, and how it must be disclosed, depends on the state and sometimes on the line; examples from California and New York are in how to increase agency revenue. Keep fees in their own column so they don’t hide a commission shortfall.

How often do endorsements change the commission?

Personal policies get them too, when a car is swapped or a driver added, but commercial accounts tend to change more during the term: vehicles, locations, payroll, additional insureds, new coverages. Each endorsement with a premium change should produce a commission line, positive or negative, usually at the policy’s rate unless the schedule says otherwise. On a busy commercial account, the term’s commission is the original line plus every endorsement and the audit, so checking only the first line misses most of the movement. How to check one is in commission on mid-term endorsements.

How does each show up on a commission statement?

Personal lines: many lines, each small, often one per policy per month or per installment, and some carriers issue a separate personal lines statement. The total looks plausible even when a few lines are missing, because no single line is large.
Commercial lines: fewer accounts but several lines per policy over the term: the original premium, endorsements, cancellations, audits, spread across separate policies (property, liability, auto, workers’ compensation) on one account. On agency bill, the same items appear on the account current as premium less commission. Lines for one account may arrive on different months’ statements.

What should you check each month for each?

Personal lines. Every policy you expect to see renewed or paid this month has a line; the rate matches the schedule for new or renewal; installment lines keep arriving; cancellations come back from the right effective date, pro rata or short rate as the policy provides; no policy appears twice.

Commercial lines. Each endorsement with a premium change has a commission line at the right rate; audits are tracked as open items until final; agency bill net remitted matches the account current; rewrites are coded new or renewal as your schedule says; fees are separated from commission.

Where Lapidar fits

Lapidar checks carrier statements line by line against your book and the rates in your schedules, for personal and commercial lines alike, and flags missing, underpaid and paid-twice commission. It is in its founding pilot, it has no customers yet, and we’ll say so until that changes.

Frequently asked questions

Do commercial lines pay higher commission than personal lines?

It depends on the carrier, product and state; rates are set in each carrier’s commission schedule. We don’t publish typical rates for either line because we have no public source that applies across carriers. Check your own schedules.

Why are premium audits mostly a commercial lines issue?

Some commercial policies, such as workers’ compensation, are priced on estimated payroll or sales and audited after the term. The audit can create additional or return premium, and commission follows it. Personal policies are rarely rated that way.

Are personal lines usually direct bill?

Often. Smaller policies, such as condo owners’ and tenants’ policies, tend to be billed direct, while larger accounts lean toward agency bill. The carrier and your agreement decide each policy.

Is a policy fee part of my commission?

No. A carrier’s policy fee or an agency’s broker fee is separate from commission and should be tracked separately. Whether an agency may charge a fee depends on state rules.
