Most business owners know one thing about their Experience Mod: they want it to be below 1.0. Beyond that, the conversation often stops.
Unfortunately, one of the most talked-about numbers in workers’ compensation is also one of the most misunderstood. While many business owners view their Experience Mod as a simple scorecard, experienced risk advisors see something completely different. They view Experience Mod as a data point that raises important questions about safety, operations, claims management, and continuous improvement.
Here’s a new way to look at and understand Experience Mod.
What Is an Experience Mod?
An Experience Modification Factor, often called an Experience Mod or EMR, is a numerical rating that compares your company’s workers’ compensation claims history to what would be expected for businesses performing similar work. A score of 1.0 represents average claims performance for your industry. A score below 1.0 generally indicates fewer losses than expected, while a score above 1.0 indicates more losses than expected.
An Experience Mod is calculated using a formula developed by workers’ compensation rating bureaus such as the National Council on Compensation Insurance (NCCI) or state rating organizations.
At first glance, that seems simple enough. The problem is that many people assume the number tells the entire story. It doesn’t. Experience Mod reflects historical claims data, not necessarily the current state of your business. More importantly, it doesn’t explain why your Experience Mod landed where it did. That’s where many misconceptions begin.
What Influences an Experience Mod?
Several factors contribute to your Experience Mod calculation, including:
- Workers’ compensation claim frequency
- Claim severity
- Employee classifications
- Payroll within those classifications
- Three years of historical claims data
- Rating bureau formulas rather than insurance carrier calculations
Each of these factors matters, but they don’t all carry the same weight. That’s one reason two companies with very different safety records can sometimes have surprisingly similar Experience Mods.
Why the Number Doesn’t Tell the Whole Story
Imagine two concrete contractors. Company A employs one hundred field employees. Over the past three years, they’ve experienced twenty relatively minor workers’ compensation claims. Because of their size, payroll, and overall exposure, their Experience Mod remains below 1.0.
Company B employs twenty-five people. During the same period, they experience one severe injury resulting from an unfortunate accident. That single claim pushes their Experience Mod above 1.0.
Which company has the stronger safety culture? If you’re only looking at the Experience Mod, you might assume Company A. If you’re looking at the underlying claims history, you might come to a very different conclusion. This is why experienced advisors rarely stop at the number itself.
They begin asking better questions:
- Was this the result of one unavoidable incident, or does it reveal a pattern of recurring injuries?
- Were the claims concentrated around one task, one department, or one supervisor?
- Has the company implemented new safety procedures since those claims occurred?
- Are injuries becoming less frequent over time?
The Experience Mod provides a number, but it can’t answer those questions. People can.
Frequency Often Tells a Bigger Story Than Severity
One of the most overlooked aspects of the Experience Mod is the relationship between claim frequency and claim severity. A single catastrophic injury can significantly impact a smaller employer’s Experience Mod simply because there are fewer employees and less payroll available to absorb the loss. On the other hand, a larger company may experience frequent minor injuries without seeing the same increase.
That doesn’t necessarily mean the larger organization has a stronger safety program. In many cases, repeated minor injuries reveal deeper operational issues. Perhaps employees aren’t consistently following procedures, or maybe training has become inconsistent. Supervisors may not be reinforcing expectations, and communication may be breaking down on the jobsite.
Individually, each claim appears small. Collectively over time, though, they can point to a trend. That’s why experienced risk advisors look beyond the Experience Mod itself, studying the claims behind the number. When they dig in, those claims often reveal opportunities to improve safety, reduce risk, and strengthen operations.
Your Experience Mod Looks Backward. Your Business Shouldn’t.
Another important characteristic of an Experience Mod is that it’s built on historical information. Most calculations rely on a rolling three-year period of claims history. That means the improvements you make today won’t immediately appear in next year’s Experience Mod. At the same time, a company that has become complacent may continue benefiting from a favorable Experience Mod until more recent claims begin influencing the calculation.
Your Experience Mod reflects where you’ve been. It should never dictate where you’re going. Organizations committed to continuous improvement don’t wait for their Experience Mod to improve before making changes. They improve hiring practices, strengthen training, refine return-to-work programs, and invest in safety because those actions create healthier workplaces and stronger businesses. The lower Experience Mod eventually follows.
Looking Beyond the Number
Too often, business owners ask one question: “Is our Experience Mod good or bad?” A better question is this: “What is our Experience Mod trying to tell us?” That simple shift changes everything. Instead of treating the Experience Mod as a report card, it becomes a diagnostic tool. It encourages leaders to investigate patterns, evaluate processes, and identify opportunities to improve before the next claim occurs. The number becomes the beginning of the conversation rather than the conclusion.
At Kraus-Anderson Insurance, we’ve found that the organizations making the greatest long-term progress aren’t necessarily the ones with the lowest Experience Mods today. They’re the ones willing to ask difficult questions:
- What can we do differently?
- Where are our blind spots?
- How can we better protect our employees?
- How do we strengthen our culture instead of simply reacting to claims?
Those conversations are leading to stronger safety programs, healthier workplaces, more engaged employees, and ultimately, better long-term workers’ compensation performance. The Experience Mod simply provides one place to start.
A Frequently Asked Question
Can a company with a higher Experience Mod have a better safety program?
Absolutely. Smaller employers can experience a significant increase in their Experience Mod from a single serious injury because they have fewer employees and less payroll to absorb the loss. Meanwhile, a much larger organization may maintain a lower Experience Mod despite experiencing numerous smaller claims. That’s why the Experience Mod should never be viewed in isolation. Understanding the claims behind the number provides a much clearer picture of an organization’s safety culture, operational practices, and opportunities for improvement.
The Bottom Line
The goal isn’t simply achieving a lower Experience Mod. Yes, there are benefits to that, but the ultimate goal is creating a workplace where no one gets hurt, employees return home safely each day, and your business continually becomes stronger than it was yesterday.
Understanding how an Experience Mod is calculated is only the first step. In Part 2 of our Experience Mod series, we’ll look at why businesses that view it simply as a score often miss its greatest value, and why relying on the number alone can lead others to make assumptions that don’t always reflect the full story.
At Kraus-Anderson Insurance, we help organizations understand the story behind their Experience Mod, identify opportunities for improvement, and build long-term strategies that strengthen safety, reduce risk, and support business growth. Let us help you understand what your Experience Mod is saying about your business, and more importantly, where it can help you go next.
