Workers' Compensation: NJ Workers’ Compensation: Profit Surge

An Analysis of Premiums, Profitability, and Trends from the NJCRIB 2025 Annual Report

Introduction

New Jersey’s workers’ compensation insurance market is one of the largest in the nation. Governed by N.J.S.A. 34:15-1 et seq., the system operates under the oversight of the New Jersey Compensation Rating and Inspection Bureau (NJCRIB), a non-profit advisory organization established in 1917 under N.J.S.A. 34:15-89 and 34:15-90.1. Each year, NJCRIB publishes a comprehensive Annual Report providing a window into the financial health and claims performance of the New Jersey workers’ compensation system. The 2025 Annual Report reveals a market that is highly profitable for carriers, steadily declining in cost per unit of payroll, and evolving in the nature and distribution of workplace injuries.

This analysis examines three dimensions of that report:

(1) the size and structure of the premium base;

(2) the profitability of the system for insurers; and

(3) the key trends in claims frequency, loss severity, and injury types that define the current landscape for injured workers, employers, and practitioners.

I. The Premium Landscape: A $2.59 Billion Market

Total Written Premium

New Jersey’s workers’ compensation market generated $2.59 billion in direct written premium during Calendar Year (CY) 2025, with total written premium across all carriers reaching $4.15 billion when accounting for reinsurance and other market participations. Net premium earned for CY 2025 stood at $2.77 billion, with net incurred losses of $1.39 billion, indicating a substantial underwriting margin.

The market consists of approximately 327,000 policies, of which an overwhelming 97% are written in the voluntary market, and only 3% remain in the residual (assigned risk) market. This composition reflects a healthy, competitive insurance marketplace in which most employers can secure coverage through normal market channels rather than the insurer-of-last-resort pool.

Rate Environment: Ten Consecutive Years of Reductions

Perhaps the most striking headline in the 2025 Annual Report is the continuation of an extraordinary rate-reduction cycle. Effective January 1, 2026, NJCRIB filed a -4.3% overall rate change — the tenth consecutive year of rate reductions since 2017 (with no rate change filed in 2021). The weighted annual manual rate has declined from $2.15 per $100 of payroll in 2017 to $1.43 per $100 of payroll in 2026— a 33.5% decline over nine years.

This sustained downward trend in the cost of coverage reflects a confluence of factors: declining claim frequency, constrained medical cost growth in the workers’ compensation line (relative to general health care), judicial and legislative reforms, and an increasingly favorable loss development environment. Employers have benefited meaningfully from these reductions, particularly those in high-manual-rate industries such as construction, manufacturing, and healthcare.

Year	Weighted Manual Rate (per $100 payroll)
2017	$2.15
2019	$2.03
2021	$1.79
2023	$1.63
2025	$1.51
2026 (filed)	$1.43

Top Carriers by Written Premium

The NJ workers’ compensation market is concentrated among a handful of major insurers. The top five carriers by direct written premium for CY 2025 were:

• NJ Manufacturers Group: $472 million

• Chubb Limited Group: $381 million

• Hartford Fire & Casualty Group: $366 million

• AmTrust Financial Services Group: $319 million

• Travelers Group: $311 million

These five carriers collectively write approximately $1.85 billion — roughly 45% of the total market premium — demonstrating the concentration of market power in a relatively small number of carriers.

II. Profitability: A Highly Favorable Environment for Insurers

Combined Ratios Signal Strong Underwriting Gains

The combined ratio is the primary measure of insurance profitability, representing the percentage of premiums that go to losses and expenses. A combined ratio below 100 indicates an underwriting profit; the lower the ratio, the greater the profit.

New Jersey’s workers’ compensation market has produced remarkably favorable combined ratios in recent years:

• CY 2023 Combined Ratio: 80.3 — an exceptional underwriting profit of nearly 20 cents on every premium dollar

• CY 2024 Combined Ratio: 94.0 — still solidly profitable, though trending toward equilibrium

A combined ratio of 80.3 in CY 2023 means that for every dollar of premium collected, only 80.3 cents went to losses and expenses — leaving nearly 20 cents of pure underwriting profit. Even the higher CY 2024 ratio of 94.0 implies a meaningful underwriting gain, supplemented by investment income on loss reserves (which in a low-frequency environment are held for years before being disbursed).

Loss Ratio Analysis

The voluntary market Policy Year (PY) 2024 loss ratio was just 31.5% — meaning that for policies written in 2024 on the voluntary market, losses were tracking at approximately 31.5 cents per premium dollar through the most recent evaluation. This is a historically low loss ratio, reflecting the fundamental health of the insurance market.

Net incurred losses of $1.39 billion against net earned premiums of $2.77 billion imply a loss ratio of approximately 50% on a calendar-year basis. The difference between the 50% calendar-year loss ratio and the far lower 31.5% policy-year loss ratio reflects the inclusion of adverse development on older accident years in calendar-year figures.

The Discount Factor: A Hidden Profitability Amplifier

A particularly striking element of the profitability picture is the magnitude of discounting applied to workers’ compensation reserves. NJCRIB’s data shows that the total discounting on earned premium in 2025 was -42.7%. This means that insurance carriers are holding reserves for workers’ compensation claims at a significant discount to their nominal future value, reflecting the long-tailed nature of WC claims and the time value of money.

The practical effect of deep discounting in a low-interest-rate-to-rising-rate environment is that carriers who built reserves during low-rate periods and are now investing at higher yields benefit from a double advantage: investment income exceeds the discount assumptions embedded in their reserves.

Maximum Weekly Benefits vs. Carrier Profits

While carriers enjoy historically favorable profitability metrics, injured workers’ maximum weekly benefits continue their modest upward trend. The 2026 maximum weekly benefit is $1,199 per week (a 3.5% increase), up from $871 in 2016, a 37.7% increase over a decade. However, this benefit level is tied to the state average weekly wage and reflects the regulatory framework established under N.J.S.A. 34:15-12 .

The gap between carrier profitability and benefit levels is a policy tension that practitioners and advocates have noted. While premium rates have declined by 33.5% since 2017, injured workers have seen benefit increases of only 37.7% over a decade, a rate barely keeping pace with inflation, and well below wage growth in many sectors.

III. Claims and Loss Trends: The Changing Face of Workplace Injury

Frequency: A 26% Decline Over a Decade

One of the most significant long-term trends in New Jersey workers’ compensation is the sustained decline in claim frequency. NJCRIB measures frequency as the number of lost-time claims per $1 million in premium. The data shows a clear and consistent downward trend:

• 2014: 9.6 claims per $1 million of premium

• 2018: 8.2 claims per $1 million of premium

• 2023: 7.1 claims per $1 million of premium

This represents a 26% decline in claim frequency over nine years. The causes are multifactorial: improved workplace safety programs, better ergonomics and injury prevention, greater use of modified duty programs, changes in the composition of employment (toward service and technology sectors and away from manufacturing), and more rigorous claims investigation by carriers. The practical effect on the system is fewer claims entering the pipeline, which directly contributes to the favorable loss ratios described above.

Severity: Modest Growth, But Medical Costs Rising as a Share

While claim frequency has declined dramatically, per-claim costs have risen modestly. The average lost-time claim cost in CY 2025 was approximately $54,000. Breaking down severity by component:

• Indemnity (wage replacement) severity: Ranged approximately $42,000–$52,000 per claim across Policy Years 2014–2023

• Medical severity: Ranged approximately $37,000–$42,000 per claim over the same period

The more important trend is the shift in the composition of losses. Medical costs have grown as a percentage of total losses:

• Policy Year 2013 (5th report): Medical = 48.7% of total losses

• Policy Year 2013 (latest evaluation): Medical = 51.3% of total losses

• Policy Year 2023: Medical = 56.9% of total losses

This shift. from less than half to more than half of the total losses being medical. reflects the increasing sophistication and cost of medical treatment for workplace injuries, including surgeries, diagnostic imaging, physical therapy, and pharmaceutical costs. As New Jersey workers’ compensation practitioners know, medical management is increasingly central to case resolution, with disputes over treatment authorization, choice of physician, and medical appropriateness becoming more common. Relevant to this dynamic is the court’s holding in Lindquist v. City of Jersey City Fire Dept., which addressed the compensability of stress-related medical claims, an area of growing exposure as medical understanding of occupational stress evolves.

Top Injury Types by Claim Count

The NJCRIB data breaks down claims by injured body part and nature of injury, providing a detailed picture of the types of workplace injuries driving the system. The top injury sites by percentage of total claim count for Policy Year 2023 are:

Injury Site	% of Total Claims (PY 2023)
Fingers	10.13%
Lower Back	9.93%
Multiple Body Parts	8.74%
Knees	7.82%
Shoulders	6.91%

Top Injury Types by Total Losses (Dollars)

Measuring by total incurred losses (rather than claim count), the picture shifts toward more severe injuries:

Injury Site	% of Total Losses (PY 2023)
Multiple Body Parts	13.51%
Shoulders	12.72%
Lower Back	12.72%
Knees	9.84%
Head/Brain	7.21%

The significance of multiple body part claims topping the loss-dollar rankings reflects the reality that the most severe and costly injuries often involve systemic or multi-system trauma, cumulative exposure injuries, and complex orthopedic conditions. Shoulder and back injuries, while individually common, represent high-cost claims because they often require surgical intervention and extended periods of temporary total disability.

The Shrinking Residual Market

One of the most dramatic trends in the 2025 Annual Report is the precipitous decline of the residual market (the Assigned Risk Plan), which serves employers unable to obtain coverage in the voluntary market:

• 2023: 61,700 risks in the residual market

• 2024: 24,800 risks — a 59.8% decline in one year

• 2025: 19,600 risks — a further 21% decline

The residual market’s share of total premium has fallen from 6.1% in 2018 to just 2.9% in 2025. While this contraction is broadly positive — reflecting the competitive voluntary market absorbing more employers — it also means the residual pool contains a higher concentration of adverse risks. The residual market loss ratio rose to 72.9% for Policy Year 2024 (compared to just 31.5% for the voluntary market), confirming the higher-risk composition of the remaining assigned-risk employers.

Legislative Developments in 2025

The 2025 Annual Report highlights several significant legislative changes affecting the New Jersey workers’ compensation system:

First Responder Mental Health Protections: New legislation expanded confidential counseling benefits for first responders following critical incidents, recognizing the occupational mental health toll on police, fire, and emergency medical personnel. This reflects a broader national trend, accelerated by COVID-19, toward acknowledging psychological injuries as compensable occupational exposures. See related case law in Brunell v. Wildwood Crest Police Dept ., addressing psychiatric injury compensability in NJ.

Wage Calculation Reform: Legislation changed the method for calculating wages for workers who receive board and lodging as part of their compensation, replacing a fixed valuation with a CPI-indexed approach. This affects the average weekly wage calculation that underpins both temporary and permanent disability benefits under N.J.S.A. 34:15-37.

Minimum Wage Increase: New Jersey’s minimum wage increased to $15.49 per hour effective January 1, 2025, indexed to the CPI. This has a downstream effect on workers’ compensation wage calculations for minimum-wage earners, indirectly increasing the cost of temporary total disability benefits for the lowest-paid injured workers.

IV. What This Means for Stakeholders

For employers, the sustained rate reductions represent a genuine cost savings — the premium per $100 of payroll is at its lowest level in decades. Employers with favorable experience records continue to benefit from experience rating credits, and the competitive voluntary market means most can obtain coverage without entering the assigned risk pool.

For injured workers, the data present a more mixed picture. While benefit levels have increased modestly, the growing dominance of medical costs in total losses means that medical management, authorization disputes, and treatment decisions are increasingly central to the adequacy of their recovery. The shift toward medical intensity underscores the importance of competent legal representation to ensure access to appropriate medical care under N.J.S.A. 34:15-15 (right to medical treatment).

For practitioners and courts, the declining frequency paired with rising per-claim medical costs means that the remaining cases in the system tend to be more complex, involving multiple body parts, significant medical treatment, and difficult causation or apportionment questions. The New Jersey Division of Workers’ Compensation and its judges continue to administer a substantial and sophisticated caseload.

For carriers, the combined ratio data confirm what investment analysts have noted: workers’ compensation in New Jersey has been an exceptionally profitable line of business for the past several years. The key question is whether the CY 2024 combined ratio of 94.0, moving toward break-even from the exceptional 80.3 in 2023, signals a reversion toward market equilibrium, or whether additional rate reductions will pressure profitability below acceptable thresholds.

Conclusion

The NJCRIB 2025 Annual Report paints a portrait of a workers’ compensation system in a prolonged period of insurer profitability, driven by declining claim frequency, controlled growth in severity, and competitive underwriting dynamics. A $2.59 billion premium base, combined ratios well below 100, and a voluntary market loss ratio of just 31.5% demonstrate that New Jersey’s workers’ compensation market has delivered consistently strong returns for carriers over the past decade.

At the same time, trends in injury types and medical cost distributions point to an evolving system: fewer claims but more complex and expensive ones, with medical management increasingly central to case value. Legislative reforms on mental health, wage calculation, and minimum wage reflect an ongoing effort to keep the statutory framework current with modern workplace realities.

Practitioners, employers, insurers, and injured workers would all do well to study these trends carefully. The data underlying the NJCRIB Annual Report is not merely actuarial history; it is the landscape within which every workers’ compensation claim, negotiation, and judicial determination unfolds.
