Understanding How Your Experience Rating Mod affects Workers’ Comp E-Mod Works (And How to Lower It)
If your workers’ comp premium is significant, your Experience Rating Mod can quietly cost you six figures. Most owners don’t understand it until it’s already hammering them for years.
At The Coyle Group, we’ve seen businesses with mods above 1.25 struggle to win contracts, while companies that actively manage their mod consistently secure better rates and maintain predictable costs.
The Bottom Line (TL;DR)
Base Premium | Mod 0.75 | Mod 1.00 | Mod 1.25 |
|---|---|---|---|
$50,000 | $37,500 | $50,000 | $62,500 |
$100,000 | $75,000 | $100,000 | $125,000 |
$250,000 | $187,500 | $250,000 | $312,500 |
Who Needs to Understand Their Mod
This matters if you have meaningful workers’ comp premium (construction, manufacturing, trucking, landscaping), your experience rating mod is 1.0+ (or unknown), you’re bidding jobs where the mod affects competitiveness, or you’re buying comp online with no strategic guidance.
According to the National Council on Compensation Insurance (NCCI), experience rating typically applies to businesses with annual premiums exceeding $5,000-$10,000.
What 40+ Years Taught Me About This Risk
After four decades advising employers on workers’ comp cost control, I’ve watched countless businesses discover their experience rating mod is costing them tens of thousands unnecessarily. Companies that thrive treat their experience mod as a financial metric, monitoring it quarterly and managing claims strategically. Those who ignore their mod usually call us when it hits 1.35 and they’re suddenly uncompetitive on bids.
What is an Experience Rating Mod?
An Experience Rating Mod (E-Mod, X-Mod, or EMR) compares your claims to similar businesses and adjusts your premium accordingly. It either debits you for worse-than-expected claims or credits you for better performance.

How the Experience Rating Mod Impacts Premium
Formula: Standard Premium × Experience Mod = Modified Premium
Example with $100,000 base:
For construction companies bidding competitively, many GCs require subcontractors to maintain mods below 1.0 just to qualify for work.
How Your Mod is Calculated
Three key components:
According to NCCI’s methodology, this lag allows claims to develop and carriers to report accurate data. Your mod reflects whether your actual losses are higher, lower, or similar to comparable businesses.
Why Experience RatingMatters
The system creates fairness by ensuring premiums reflect actual risk rather than subsidizing poor performers. It rewards employers with fewer claims through lower premiums and encourages comprehensive safety programs.
According to OSHA, effective safety programs can reduce injury costs by 20-40%, directly improving your mod over time.
The Cost ofIgnoring Your Mod
Doing nothing means:
Active management delivers:
A manufacturer with $200,000 base premium whose mod rises from 1.0 to 1.3 pays an extra $60,000 annually, $180,000 over three years in unnecessary costs.
The 3-Step Plan to Lower Your Mod
Step 1: Get Visibility
Request your 5-year loss runs, mod worksheet from NCCI, and identify top drivers. Focus on claims appearing across multiple years, inflated open reserves, and the ratio of medical-only vs. lost-time claims.
Step 2: Fix Preventable Leakage
Claims handling:
Return-to-work strategy:
According to NCCI’s Experience Rating Adjustment, medical-only claims are reduced 70% in mod calculations, while indemnity payments go in at nearly full value. This makes return-to-work programs extremely valuable.
Step 3: Reduce Frequency and Severity
Safety management:
Practical controls:
Understanding how premiums are calculated helps translate these efforts into savings.
CommonMistakes Costing You Money
Mistake #1: Nobody Monitors Claims
Without quarterly loss run reviews and oversight, claims adjusters operate unchecked, and premiums become unpredictable.
Fix: Assign one executive as “claims owner” and schedule quarterly reviews.
Mistake #2: Wrong Broker Approach
Online or payroll-integrated purchasing provides minimal strategy.
Fix:If your mod is 1.0+, work with brokers offering quarterly claim reviews, safety program development, and mod projections, not just policy placement.
Mistake #3: Accepting High Reserves
Adjusters often set reserves conservatively high, directly increasing your mod even if claims settle lower.
Fix:Request reserve justification for claims >$25,000 and challenge with medical documentation quarterly.
Real-World Example: Reducing a 1.13 Mod to 0.98
A general contractor came to us with a 1.13 mod, too high for many contracts they wanted to bid on.
