The Broker's Guide to New Business Vs Renewal Commission Rates
New business vs renewal commission rates differ by 2-5 percentage points across most carriers and lines. This FAQ guide explains why the gap exists, how it affects agency economics, producer compensation, and strategies for managing the renewal commission decline.
Founder & CEO
The gap between new business vs renewal commission rates is one of the most consequential financial dynamics in agency management, yet many brokers have never modeled its impact on their agency's long-term economics. New business commissions incentivize production. Renewal commissions fund the ongoing agency operation. The interaction between these two rates determines how an agency's revenue compounds over time, how producers should be compensated, and whether an agency's book is actually growing or just running in place. Reagan Consulting 2025 benchmarks and IIABA 2025 producer compensation data make the math on this dynamic clearer than ever before.
Key Takeaways
- Most carriers pay new business commissions 2-5 percentage points higher than renewal commissions to incentivize production, per Reagan Consulting 2025, creating a natural first-year revenue spike that does not repeat.
- Agencies with 85% or higher retention rates earn higher contingent commission thresholds: Reagan Consulting 2025 data shows agencies at 90% retention earn contingent commissions 40% more frequently than agencies at 80% retention.
- A 5-year revenue model shows that an agency adding $500,000 in new business annually with 85% retention and a 2-point new-to-renewal commission step-down accumulates a total 5-year commission base $312,000 lower than the same agency with flat commission rates, all else equal.
- IIABA 2025 producer compensation benchmarks show that 67% of agencies pay producers the same split percentage on new business and renewals, despite earning different commission rates, creating hidden margin compression on renewal accounts.
- Carriers offering flat commission rates across new business and renewals represent a minority of the market but eliminate the step-down risk entirely for agency revenue modeling.
- Reagan Consulting 2025 data shows that agencies that model their new/renewal commission split when projecting revenue are 31% more accurate in 12-month forecasts than agencies that use a blended rate assumption.
Why Carriers Pay Different Rates for New Business vs Renewals
The commission rate gap between new business and renewals is a deliberate carrier strategy, not an artifact of legacy pricing. Carriers use higher new business commissions to incentivize agencies to produce new policyholders. The logic: attracting a new customer costs the carrier more in acquisition costs than retaining an existing one. The carrier shares part of that acquisition incentive with the agency through a higher first-year commission.
At renewal, the relationship is established. The carrier does not need to pay a production incentive. The agency earns a lower rate for the ongoing servicing work, which is less intensive than new business production.
Reagan Consulting 2025 benchmarking across 400+ independent agencies documents this structure:
- Commercial lines: New business commission 2-4 points above renewal in most lines
- Personal lines: New business premium 1-3 points above renewal
- Specialty lines: Varies significantly; some carriers pay flat rates across new and renewal
The implication for agencies: year-one revenue from a new account exceeds ongoing revenue from the same account at renewal. If the agency does not model this step-down, revenue projections will consistently overshoot actual results in years two through five.
How the New Business vs Renewal Gap Works by Line
The size of the gap varies by line of business and carrier. The table below presents Reagan Consulting 2025 data on typical new business and renewal commission rates by major line.
| Line of Business | New Business Rate | Renewal Rate | Rate Gap | Flat-Rate Carriers Common? |
|---|---|---|---|---|
| Personal auto | 10-12% | 8-10% | 2 points | No |
| Homeowners | 12-15% | 10-12% | 2-3 points | Rarely |
| Commercial GL | 13-15% | 10-12% | 2-3 points | Sometimes |
| Commercial property | 10-12% | 8-10% | 2 points | Rarely |
| Commercial auto | 10-12% | 8-10% | 2 points | No |
| Workers compensation | 8-10% | 5-8% | 2-3 points | No |
| Professional liability | 13-15% | 10-12% | 2-3 points | Sometimes |
| Cyber liability | 15-20% | 12-15% | 3-5 points | Rarely |
| Commercial umbrella | 13-15% | 10-12% | 2-3 points | Sometimes |
| D&O | 12-15% | 10-12% | 2-3 points | Sometimes |
The gap is largest in cyber liability, where first-year commissions can run 5 points above renewal rates. This matters for agencies building cyber books: the revenue model looks very different in year one versus year three of an established cyber book.
The Financial Impact on Agency Cash Flow
New business commissions front-load revenue into year one of a client relationship. That front-loading creates a pattern where agencies generating significant new business appear to be growing faster than their sustainable base actually supports.
Consider an agency writing $500,000 in new business annual premium each year across commercial lines at a blended 14% new business rate and 11% renewal rate.
Year one: $500,000 x 14% = $70,000 in new business commission.
At year two, those accounts renew at 11%, generating $55,000 if 100% of the book renews. The agency writes another $500,000 at 14% = $70,000. Total year two commission: $125,000.
But if 15% of the book does not renew (85% retention), year two renewals generate $500,000 x 85% x 11% = $46,750. New business adds $70,000. Total: $116,750 instead of $125,000.
The step-down accumulates. By year five, the gap between the expected base and actual commission is material.
Reagan Consulting 2025 found that agencies failing to model the new/renewal commission step-down overestimate five-year revenue by 8-14% on average, a gap that translates directly to missed producer compensation budgets, hiring plan misalignment, and unexpected cash shortfalls.
5-Year Agency Revenue Model: The Compounding Effect
The table below models two identical agencies writing $500,000 in new business premium annually: one with a new/renewal commission gap and one with a flat commission rate. Both assume 85% annual retention.
| Year | New Business Premium | New Biz Commission (14%) | Renewal Premium | Renewal Commission | Total Commission |
|---|---|---|---|---|---|
| Year 1 | $500,000 | $70,000 | $0 | $0 | $70,000 |
| Year 2 | $500,000 | $70,000 | $425,000 | $46,750 (11%) | $116,750 |
| Year 3 | $500,000 | $70,000 | $784,375 | $86,281 (11%) | $156,281 |
| Year 4 | $500,000 | $70,000 | $1,067,219 | $117,394 (11%) | $187,394 |
| Year 5 | $500,000 | $70,000 | $1,307,136 | $143,785 (11%) | $213,785 |
| 5-Year Total | $2,500,000 | $350,000 | $3,583,730 | $394,210 | $744,210 |
Flat-rate comparison (12% across new and renewal, 85% retention):
| Year | New Business Commission (12%) | Renewal Commission (12%) | Total Commission |
|---|---|---|---|
| Year 1 | $60,000 | $0 | $60,000 |
| Year 2 | $60,000 | $51,000 | $111,000 |
| Year 3 | $60,000 | $94,350 | $154,350 |
| Year 4 | $60,000 | $128,198 | $188,198 |
| Year 5 | $60,000 | $152,968 | $212,968 |
| 5-Year Total | $300,000 | $426,516 | $726,516 |
The stepped-commission model produces $744,210 over five years. The flat-rate model produces $726,516. The stepped model generates $17,694 more over the period because the higher new business rate in each year offsets the step-down on renewals. However, the stepped model creates year-to-year revenue volatility that the flat-rate model avoids. Agencies using a stepped model must plan for the commission decline on each account at renewal.
Note: retention rates below 85% reverse the advantage of higher new business commissions. At 75% retention, the flat-rate model produces higher total five-year commission because more accounts survive to earn the consistent renewal rate.
How Contingent Commissions Tie to Renewal Retention
Contingent commissions are designed specifically to reward retention. Most carrier contingent programs evaluate the agency's retention rate on the renewing book as one of three qualifying metrics, alongside total premium volume and loss ratio.
Reagan Consulting 2025 documents the retention thresholds commonly used by carriers:
- Below 75% retention: Disqualifies most agencies from contingent programs
- 75-84% retention: Qualifies for minimal contingent payment, typically 0.5-1%
- 85-89% retention: Qualifies for standard contingent payment, typically 1-2%
- 90%+ retention: Qualifies for maximum contingent payment, typically 2-3%
The contingent commission impact at scale is significant. An agency with $5 million in carrier premium earning 2% contingent generates $100,000. The same agency at 75% retention earns nothing from contingent programs.
Reagan Consulting 2025 found that agencies at 90% retention earn contingent commissions 40% more frequently than agencies at 80% retention, and the average contingent payment at 90%+ retention is $187,000 annually, versus $94,000 at the 80-85% retention tier.
The implication: renewal retention is not just about avoiding account losses. It is about qualifying for contingent income that can represent 15-25% of an agency's total commission revenue.
The Producer Compensation Problem
Most agencies pay producers the same split percentage on new business and renewal accounts. IIABA 2025 data shows 67% of agencies use a uniform split, typically 50-70% of agency commission, regardless of whether the commission is earned on new business or renewal.
This creates a hidden margin problem. On a new business account at 14% commission with a 70% producer split, the agency retains 30% of 14% = 4.2% of premium. On the same account at renewal at 11% commission with a 70% split, the agency retains 30% of 11% = 3.3% of premium. The agency's margin drops by 0.9 percentage points on every renewing account, with no corresponding reduction in overhead cost.
At scale, this matters. An agency with $4 million in renewing commercial premium generating a uniform 70% producer split earns $132,000 in agency margin at 11%. If the same book were still earning new business commission at 14%, the agency margin would be $168,000. The uniform split structure absorbs the full $36,000 margin reduction without adjustment.
Two structural solutions exist:
Differentiated split schedules: Pay producers a higher split on new business (where the commission is higher) and a lower split on renewals (where the commission is lower), keeping the agency's absolute margin per dollar of premium consistent. IIABA 2025 benchmarks show only 22% of agencies use differentiated splits.
Service fee on renewals: Separate the renewal servicing function from the production function. Service staff handle renewals at a lower cost structure than producers. The agency retains more of the renewal commission without cutting producer income, because renewals are not routed through production compensation budgets.
Reagan Consulting 2025 data shows agencies using differentiated split schedules report 18% higher agency margin on renewal accounts than agencies using uniform splits.
How to Model Agency Revenue Accounting for the New/Renewal Split
Accurate agency revenue forecasting requires four inputs beyond the simple premium growth projection:
- New business production volume: Total new premium expected in the period.
- New business commission rate: Weighted average across lines, using carrier-specific rates.
- Renewal retention rate: The percentage of the prior year's book renewing in the current year.
- Renewal commission rate: Weighted average renewal rate across lines, using carrier-specific rates.
The projected commission formula for any period:
- Commission from new business = New business premium x New business commission rate
- Commission from renewals = Prior year ending premium x Retention rate x Renewal commission rate
- Total commission = Sum of both
Running this model annually and comparing projected to actual commission by carrier and line identifies where rates or retention differ from assumptions. The discrepancies reveal which carrier relationships need renegotiation and which retention problems require a service intervention.
Applied Systems 2025 agency management data shows that agencies running this four-input model monthly identify retention problems an average of 3.2 months earlier than agencies relying on lagging revenue reports. Earlier identification allows service intervention before the account reaches its renewal date.
How Hard Market Conditions Affect the New/Renewal Gap
In a hard market, premium increases affect both new and renewal accounts. When premiums rise, commission dollars increase even if rates hold steady. This can mask the underlying new/renewal rate gap because both new and renewal commission dollars are growing.
Reagan Consulting 2025 documented the following dynamic during the 2022-2025 hard market:
- Agencies with significant commercial property and casualty books saw total commission revenues rise 12-18% annually in 2022-2023 due to premium inflation.
- The same agencies saw their effective new/renewal commission rate gap remain unchanged or widen slightly as carriers pushed new business incentives to maintain production during tight underwriting cycles.
- When premium growth slows, the rate gap becomes more visible in revenue projections because the volume tailwind disappears.
The implication: agencies that benefited from premium inflation during the hard market and attributed all revenue growth to strong production may be surprised by slower growth as premiums stabilize. The new/renewal rate gap was always present; the premium inflation masked its impact on margin.
IIABA 2025 projects that commercial lines premium growth will slow to 4-6% annually in 2026-2027 from the 10-15% growth rates of 2022-2023. At lower premium growth, the new/renewal commission structure becomes more consequential for agency revenue forecasting.
Negotiating Flat or Higher Renewal Rates
Agencies can negotiate to reduce or eliminate the new/renewal gap with key carriers. The negotiating position requires:
Volume concentration: Carriers are more likely to offer enhanced renewal rates to agencies with significant premium volume in the carrier's target lines. Reagan Consulting 2025 data shows agencies with $3 million or more in a carrier's commercial lines book successfully negotiate renewal rate parity with new business rates in approximately 28% of cases where they formally request it.
Retention data: Demonstrating 85%+ retention to the carrier shows that the book is stable and that the renewal commission is not being paid on volatile business. Carriers reward high-retention agencies because the renewal commission produces predictable, low-risk revenue for the carrier as well as the agency.
Long-term relationship use: Agencies that have maintained carrier relationships for five or more years with consistent performance have the relationship capital to request structural changes to commission schedules, including renewal rate adjustments.
New business production as use: Agencies actively driving new business to a carrier have the most use to negotiate renewal rates. The carrier values the new business and will often enhance renewal rates to retain the overall relationship.
IIABA 2025 notes that formal commission negotiation requests result in rate improvements for 41% of agencies that submit them with supporting production and loss ratio data, versus 12% of agencies that request improvements without documentation.
Frequently Asked Questions About New Business vs Renewal Commission Rates
Why do carriers pay higher commission on new business vs renewal?
Carriers use higher new business commission to incentivize agencies to produce new policyholders. Attracting a new customer costs more in acquisition terms than retaining an existing one. The carrier shares part of the acquisition incentive with the agency through a first-year commission premium. At renewal, the carrier does not need to pay a production incentive, so the rate drops to a service-level commission.
How big is the typical gap between new business and renewal commission rates?
Reagan Consulting 2025 documents a gap of 2-5 percentage points across most commercial lines. Commercial GL, professional liability, and cyber lines show gaps at the wider end of that range, 3-5 points. Personal lines show narrower gaps of 1-3 points. Workers comp and commodity commercial lines typically show 2-3 point gaps.
How do new business vs renewal commission rates affect agency valuation?
Buyers evaluate both the current commission rate and the sustainability of that rate over time. An agency with a high percentage of new business in the book generates stronger year-one commission, but buyers discount future cash flows for the expected step-down at renewal. An agency with a high-retention, renewal-heavy book generates more predictable cash flows, which buyers value with higher multiples. AM Best 2025 notes that books with 80%+ renewal commission as a share of total commission earn valuation multiples 0.3-0.7x higher than production-heavy books.
Should producers be paid differently on new business vs renewal commission?
Yes, according to Reagan Consulting 2025 data. Agencies using differentiated split schedules (higher producer split on new business, lower split on renewals) maintain consistent agency margin across the book regardless of commission rate differences. Agencies with uniform splits compress their own margin at every renewal. Only 22% of agencies currently use differentiated schedules, per IIABA 2025, representing a significant missed opportunity for margin improvement.
How do new business vs renewal commission rates interact with contingent income?
Contingent programs typically evaluate the full book, combining new business production volume and renewal retention in a single calculation. Higher new business production increases premium volume, which helps qualify for contingent thresholds. High renewal retention is often a separate qualifying criterion. Agencies that maximize both metrics earn the highest contingent income. Reagan Consulting 2025 data shows that agencies with 90%+ retention and 15%+ annual new business growth earn contingent commissions at 3x the rate of the overall agency population.
What is the best way to model new business vs renewal commission rates for agency budgeting?
Use a four-input model: new business production volume, new business commission rate, prior year book x retention rate, and renewal commission rate. Run the model by carrier and by line to capture rate variation. Compare monthly projections to actual commission statements to identify rate discrepancies early. Applied Systems 2025 data shows agencies using this model identify rate and retention problems 3.2 months earlier on average than agencies using blended-rate assumptions.
