How Ohio Sets Workers' Compensation Rates
Ohio uses a class‑based rating system where each job type is assigned a classification code. Rates are calculated by multiplying the class's manual rate (set by the Ohio Bureau of Workers' Compensation) by the employer's experience modification factor, which reflects the company's past claim history.

Key Components of the Rate Formula
The basic formula is:
- Manual Rate (per $100 of payroll) × Payroll × Experience Modifier = Premium
Manual rates are updated annually based on statewide loss costs, medical inflation, and legislative adjustments. The experience modifier can lower or raise a premium by up to 30 % depending on safety performance.
Recent Rate Trends in Ohio
For 2024, the Ohio Bureau reported a modest 2‑3 % increase in manual rates for high‑risk classes such as construction and manufacturing, while low‑risk office categories saw flat or slightly reduced rates. Medical cost growth and a rise in claim frequency are the primary drivers.
Impact on Different Industries
Below is a snapshot of typical manual rates for common Ohio classifications:
| Industry | Class Code | Manual Rate ($/100 payroll) |
|---|---|---|
| Construction – General | 5401 | 2.85 |
| Manufacturing – Fabrication | 5601 | 2.40 |
| Healthcare – Nursing | 6205 | 1.90 |
| Office – Administrative | 8810 | 0.95 |
Employers should compare their own premiums against these benchmarks to gauge whether their experience modifier is favorable.
Factors That Can Alter Your Rate
Beyond the experience modifier, several actions can affect the final premium:
- Implementing robust safety programs can lower the modifier over time.
- Accurate payroll reporting prevents over‑charging.
- Participating in the Ohio Workers' Compensation Self‑Insurance Fund may offer rate flexibility for large firms.
