Experience Modification Rate (EMR) — Workers’ Comp
Your experience modification rate (EMR or “mod”) is a multiplier applied to your workers’ comp base premium. An EMR of 1.0 is average. Below 1.0 earns a credit (you pay less). Above 1.0 adds a surcharge (you pay more). For Florida contractors, the EMR can be the single largest factor in your WC cost.
How the EMR Is Calculated
NCCI calculates your EMR using 3 years of loss history (excluding the most recent policy year). The formula compares your actual losses to the expected losses for your industry and payroll size. Frequency of claims matters more than severity — multiple small claims can raise your EMR more than a single large claim.

How to Lower Your EMR
The most effective strategies: implement a formal return-to-work program (reduces claim duration and cost); invest in safety training and OSHA compliance; report claims promptly and manage them actively; correct class code misclassifications that inflate your expected losses; and review your NCCI unit stat report annually for errors.

EMR and Contractor Bidding
Many general contractors and project owners require subcontractors to have an EMR below 1.0 or 0.95 to bid on commercial projects. A high EMR can disqualify you from lucrative contracts. Improving your EMR is both a cost-reduction and a business-development strategy.
