Across the 3 states we track, filed loss costs for class 9079 range from $0.52 in Oregon to $2.13 in New Jersey — about a 4.1× difference. That spread reflects each state's own injury experience and whether it adopts NCCI advisory loss costs or files through an independent rating bureau such as California's WCIRB, New York's NYCIRB, or Pennsylvania's PCRB.
Nationally, Workers' Compensation carriers ran a 45.1% loss ratio, a 12% underwriting profit, and a 13% return on net worth (NAIC 2023) — the line-level economics behind the filed loss costs above. A class's filed loss cost is the regulator-approved starting point; how profitable it is for carriers to write shapes the loss-cost multipliers you actually pay. These figures come from the NAIC Report on Profitability by Line by State.
How your Workers' Comp rate is set
Your NCCI class code classifies the work your employees do by injury risk — it's the single biggest driver of your Workers' Comp base rate. The filed loss cost above is the only public, regulator-approved piece; your actual premium is:
Filed loss cost × carrier LCM × experience modifier × (payroll ÷ $100)
Most states use NCCI's loss-cost guidance; independent-bureau states (e.g., California/WCIRB, New York/NYCIRB, Pennsylvania/PCRB) and monopolistic state funds (e.g., Ohio BWC) file their own — which is why the same class code carries different filed rates by state above.
Methodology
Each loss cost is drawn from a public state-DOI rate filing (via the state's SERFF portal) or a public NCCI State Advisory Forum summary, traceable by its filing reference. Loss costs are per $100 of payroll before the carrier's loss-cost multiplier; your actual rate depends on your carrier's LCM, experience modifier, and state.
