What You Need to Know
Workers' compensation insurance provides medical benefits, wage replacement, and rehabilitation services to employees injured on the job, regardless of fault. It also shields employers from lawsuits by injured workers (exclusive remedy doctrine). Required in 49 states for employers with at least one employee (Texas being the exception where it is optional). Premiums are calculated as a rate per $100 of payroll and vary significantly by job classification.
Workers' Compensation Insurance Cost by Business Size
| Business Size | Annual Revenue | Typical Premium | Notes |
|---|---|---|---|
| Micro Business (1–4 employees) | Under $500K payroll | $500–$5,000/yr | Highly variable by class code. Office: $200–$800. Construction: $3,000–$15,000. |
| Small Business (5–24 employees) | $500K–$2M payroll | $2,000–$25,000/yr | EMR begins to apply once you've been in business 3+ years. |
| Mid-Size (25–100 employees) | $2M–$8M payroll | $15,000–$100,000/yr | At this level, return-to-work programs and safety investments have significant ROI. |
| Large Employer (100+ employees) | Over $8M payroll | $75,000–$500,000+/yr | Large-deductible and captive programs become cost-effective. Group rating available in many states. |
What Determines Your Premium?
- Job Classification Code (Very High impact) — Office clerical pays $0.15–$0.40 per $100 payroll. Roofing can cost $25–$45 per $100 payroll. Correct classification is critical — review with your agent annually.
- Experience Modification Rate (EMR) (High impact) — Your EMR multiplies your entire premium. An EMR of 0.80 saves 20%. An EMR of 1.50 adds 50%. Safety programs and return-to-work plans are the primary levers to improve your EMR.
- Total Payroll (High impact) — Premium scales directly with payroll. $1M in payroll at a 2.00 rate = $20,000 base premium. Accurate payroll reporting prevents audit surprises.
- State (High impact) — California rates are among the highest nationally. Texas, Florida, and Ohio rates are typically lower. Ohio requires purchase through the BWC (monopolistic state).
- Claims History (High impact) — Each lost-time claim can increase your EMR by 10–25%. A single severe claim can affect your EMR for 3 years. Medical-only claims have about 30% of the EMR impact of lost-time claims.
- Deductible (Medium impact) — Large-deductible plans (per-claim deductibles of $25K–$500K) can reduce premium 15–40% for large employers who can absorb claim costs.
- Safety Programs (Medium impact) — Documented safety programs can qualify for schedule credits of 5–15%. Group rating programs in some states can provide discounts of 30–53%.
