Learn how an Experience Modifier adjusts Workers Compensation premiums based on historical claims performance and why it is one of the most important factors in commercial insurance rating.
Not every business presents the same level of risk. Two companies may have identical payroll, classifications, and operations, yet pay different Workers Compensation premiums because of their claims history. The Experience Modifier adjusts premium to reflect historical loss performance. Organizations with better-than-expected claims experience generally receive lower modifiers. Organizations with poorer claims performance generally receive higher modifiers.
Standard rating assumes average loss experience across similar businesses. The Experience Modifier recognizes that some organizations consistently perform better or worse than the average. It rewards strong loss performance and increases premiums for organizations with higher historical losses.
Two contractors may have:
One company may have very few workplace injuries, while the other experiences frequent claims. The Experience Modifier allows insurance pricing to reflect those differences.
The modifier is applied as a multiplier during the premium calculation.
A simplified formula looks like this: Calculated Premium × Experience Modifier = Adjusted Premium
For example:
Premium Before Modifier: $100,000
Experience Modifier: 0.85
Final Premium: $85,000
The modifier directly affects the final premium.
The Experience Modifier is centered around 1.00.
Better-than-average historical loss performance. Premium generally decreases.
Average historical loss performance. Premium remains unchanged.
Higher-than-average historical loss performance. Premium generally increases.
Although calculation methodologies vary by jurisdiction and rating organization, common factors include:
The modifier is based on statistical analysis rather than underwriter judgment.

These terms are closely related but have different meanings.
The calculation methodology.
The numerical result. Very concise.
In simple terms: Experience Rating is the process. Experience Modifier is one of the results.
These two adjustments serve different purposes.
Both may affect premium, but they originate from different rating processes.
Improving workplace safety can reduce future claims. Over time, fewer and less severe claims may contribute to a more favorable Experience Modifier and lower Workers Compensation premiums.
Businesses often invest in:
These efforts can improve long-term claims performance and positively influence future modifiers. For insurance carriers, modifiers improve pricing accuracy and reward safer businesses.
