What Underwriters Do
Underwriters evaluate a business's exposure to workplace injury risks and decide whether to issue a workers‑comp policy, at what rate, and with which conditions. They use statistical data, industry benchmarks, and company‑specific information to set a price that reflects expected claim costs and profit margins.

Key Data Collection Steps
1. Business Profile: Industry, employee count, payroll, and location.
2. Claims History: Number, severity, and frequency of past claims.
3. Safety Programs: Training, safety audits, and injury prevention measures.
4. Operational Details: Work processes, equipment, and hazards.
Risk Classification and Rating
Underwriters assign a classification code based on the business's industry and job duties. Each code has a standard rate table that reflects typical loss experience. Adjustments are made for:
- Claims history (positive or negative experience modifiers)
- Safety program effectiveness (discounts for proven programs)
- Payroll growth or decline
- Geographic risk factors
Example Table of Common Classifications
| Classification | Typical Loss Ratio | Notes |
|---|---|---|
| Manufacturing – Assembly | 2.5–3.5 | High physical contact |
| Office‑Based | 1.0–1.5 | Low physical risk |
| Construction – Heavy Equipment | 3.0–4.0 | High injury potential |
Pricing Determination
Premiums result from multiplying the base rate by the payroll amount and applying any experience or safety adjustments. Insurers may also add a profit margin and a risk loading for high‑variance businesses.
Policy Issuance and Underwriting Approval
Once the rate is set, the underwriting team reviews the application, verifies data, and may request additional information or site inspections. Approval leads to policy issuance, coverage commencement, and ongoing monitoring of claims activity.
Post‑Issue Monitoring
Underwriters track claim trends and safety improvements. Significant changes can trigger rate adjustments or policy renewals, ensuring the premium continues to reflect actual risk.
