Background on New Jersey Workers Compensation Rates
In New Jersey, workers' compensation premiums are calculated annually by the state's Department of Labor & Workforce Development (DLWD). The 2020 rates were finalized in early 2020 after reviewing industry data, claim history, and economic trends. Employers pay these premiums to insurers who then cover medical care, wage replacement, and rehabilitation for injured employees.

How the 2020 Rates Were Determined
The rate-setting process uses a statistical model that incorporates several key variables: the employer's industry classification (NAICS code), payroll size, claims history, and loss adjustment expense (LAE). For 2020, the DLWD adjusted the rate base to account for a 2.8% increase in average claim severity and a 1.2% rise in medical inflation. Insurers also reported higher administrative costs, prompting a modest premium bump.
Rate Base and Class Codes
Each business falls into a specific class code that reflects typical injury risk. For example, construction (NAICS 236) and manufacturing (NAICS 31‑33) usually attract higher rates than retail (NAICS 44‑45). The 2020 rate base for the average employer with a payroll of $1,000,000 was set at $2.10 per $100 of payroll. This figure varies by class code, with construction at $2.70 and retail at $1.60.
Premium Calculation Formula
Premium = (Rate Base × Payroll ÷ 100) × Safety Factor × Experience Modification (EM). The safety factor, typically 1.00 for most employers, can be reduced if the business demonstrates strong safety programs. The EM reflects past claim frequency and severity relative to the national average; a lower EM means a lower premium.
Key Factors Impacting 2020 Premiums
1. Claim Frequency: Employers with a higher number of claim reports saw increased EMs, pushing premiums up.
2. Medical Inflation: Rising costs for outpatient services and prescription drugs contributed to the overall premium increase.
3. Safety Programs: Companies that implemented OSHA-compliant safety training received a 5% discount on the safety factor.
4. Payroll Growth: A 4% payroll increase without a corresponding safety improvement raised the rate base proportionally.
Comparative Table of 2020 Class Rates
| Industry Class | Rate Base ($/100 payroll) | Typical EM |
|---|---|---|
| Construction (236) | 2.70 | 1.15 |
| Manufacturing (31‑33) | 2.40 | 1.10 |
| Retail (44‑45) | 1.60 | 0.95 |
| Healthcare (62) | 2.00 | 1.05 |
Strategies to Manage Premium Costs
- Conduct regular safety audits and document findings to qualify for safety factor reductions.
- Invest in ergonomic equipment to lower claim severity.
- Use an experienced claims management team to resolve disputes quickly, reducing LAE.
Implications for Employees
Employees injured in 2020 benefited from a streamlined claims process that allowed most medical expenses to be covered within 30 days. Wage replacement rates remained at 60% of average weekly wage, capped at 85% of the employee's prior earnings. Employers with low EMs provided faster payouts, improving employee satisfaction.
Looking Ahead
While the 2020 rates reflected a moderate rise, the DLWD announced a 2021 review that could introduce further adjustments based on post‑COVID recovery trends. Businesses should monitor upcoming announcements and adjust safety protocols accordingly.
