Your workers compensation renewal comes in and the premium is higher than last year—again. You haven’t had a major claim. You run a tight operation. So why does the number keep going up?
Few business owners have a background in workers comp rating, so wondering what’s behind the number is natural. Payroll, job classifications, and carrier rates all play a part. For many Central New York contractors and small business owners, one more piece is a calculation they may not have seen: the experience modification factor.
At the Horan insurance agency, we’re an independent agency working with multiple carriers across Central New York. That gives us an informed view of how workers comp costs come together at renewal, which an agency tied to one carrier may not have. Understanding the factor can help you make more informed decisions at renewal time.
This article covers what the factor is, how the New York Compensation Insurance Rating Board calculates it, and what it means above or below 1.0. It also covers steps CNY business owners may take to manage it over time.
How Does the Experience Modification Factor Work as Your Workers Comp Scorecard?
The experience modification factor is a multiplier applied to your workers compensation base premium. The New York Compensation Insurance Rating Board calculates it using your actual claims history compared to what it expects other businesses of your size and type to generate. Think of it as a performance score—one that follows your business into every renewal conversation.
A factor of 1.0 is the industry average. It means your claims experience is close to that of similar businesses. A factor below 1.0—say, 0.85—means your claims history is better than average and your premium gets a credit. A factor above 1.0—say, 1.20—means your history is worse than average and your premium gets a debit.
What That Looks Like in Real Dollars
The math is straightforward. If your base premium is $50,000 and your experience modification factor is 0.85, you pay $42,500. If it’s 1.20, that same base premium becomes $60,000. That’s a $17,500 swing on the same base premium, driven by claims history in this example.
For a CNY contractor in construction, manufacturing, or landscaping, that difference can be the margin between a profitable year and a difficult one.
Do Several Small Claims Affect Your Experience Modification Factor More Than One Large Claim?
They can. The Rating Board’s plan counts each claim only up to a split point set for your business’s size. One large claim has a limited effect, while several claims can add up.
This means several smaller claims—a sprained wrist here, a slip-and-fall there—can push your experience modification factor higher than a single serious injury might.
The plan also caps the factor when your experience period holds only a few claims. With one claim, the factor can’t exceed 1.12. With two claims, the cap is 1.40, and with three, it’s 1.75.
For employers with demanding manual work, a pattern of small, preventable claims can add up without any single event raising a red flag.
What Goes Into the Rating Board’s Calculation of Your Factor?
The Rating Board recalculates your factor each year. In most cases, it uses three policy years of data and leaves out the most recent one. The data includes:
- The number of claims filed during the experience period
- The amount paid on each claim (both medical and indemnity)
- Incurred amounts, meaning what the insurer has reserved for open claims
- Your payroll, which determines the expected losses for a business your size
Because incurred losses include reserves, an open claim can raise your factor even if it pays less than the reserve, until the reserve changes or the claim closes. This is one reason claim management matters throughout the life of a case, not just at the point of injury.
How Can You Work to Improve Your Experience Modification Factor Over Time?
Business owners may be able to improve their factor over time, though it can’t change overnight. Owners who take a systematic approach to safety and claim management may reach renewal in a more favorable position than those who wait for a problem to appear.
Approaches worth considering include:
- Implementing a formal safety program. New York follows federal Occupational Safety and Health Administration standards for private employers, and some, such as hazard communication, call for a written program and training. Even where one isn’t required, documented training, equipment inspections, and incident reports can give you a record that may support your case if someone disputes a claim.
- Reviewing open claims. Work with your carrier’s claims adjuster—and your agent—to monitor the status of open claims. High reserves or stalled cases can inflate your factor even when the payout is modest.
- Raising concerns about a claim in time. If you question whether a claim is compensable, talk with your carrier. The carrier or employer can file the Board’s Notice of Controversy (form C-7). Section 25 of the Workers’ Compensation Law sets a 25-day deadline after the Board mails a notice of indexing, and a late filing can limit the defenses available.
- Tracking near-miss incidents. Near-misses often come before workplace injuries and go unreported. A consistent internal reporting culture can identify hazard patterns before they result in compensable claims.
Can a Return-to-Work Program Help Manage Your Experience Modification Factor?
It may. A formal return-to-work program may help reduce claim costs, but no program can promise a lower factor.
The Workers’ Compensation Board describes an effective return-to-work program as a recommended practice. When an injured employee returns to modified duty, indemnity payments may shrink, and that may lower the losses that feed your factor.
Our guide to return-to-work programs in New York covers what a written program may include.
Take a business like a Cicero-area general contractor or a North Syracuse manufacturer with a seasonal workforce. A structured return-to-work program can also reduce the disruption that comes with an extended employee absence.
How Do You Review Your Experience Modification Factor Worksheet Before Renewal?
Request the worksheet, then check its payroll, classification, and claim entries against your own records.
The Rating Board calculates the factor and publishes a worksheet showing how your payroll and claims data became the final modifier. Your carrier has access to it, and employers or their authorized representatives can request a copy from the Rating Board.
Many business owners don’t request this document or review it. However, errors in payroll classification, duplicate claim entries, or misattributed losses do occur—and each can inflate your factor.
Before your next renewal, ask your agent to walk through your experience modification factor worksheet with you. If your factor has increased and the reason isn’t obvious, the worksheet may reveal a data issue worth raising with your carrier or the Rating Board.
An employer or its representative can also appeal a modification factor through the Rating Board’s appeal process.
A Hypothetical Look at How the Worksheet Can Surface Hidden Costs
A worksheet review can surface data errors that inflate a premium. Consider a hypothetical scenario: a small landscaping company in Onondaga County with eight employees and a base workers comp premium of $40,000.
At renewal, the owner notices the experience modification factor has climbed from 1.0 to 1.30, pushing the premium to $52,000. The owner requests the worksheet and finds that one claim appears twice, and another is still open with a reserve the owner wants to review with the carrier.
Working with the agent to raise those entries with the carrier may lead to corrected loss values. If the Rating Board receives corrected reports, it can revise the current factor and up to two preceding ones.
The scenario is illustrative, not guaranteed, but it reflects the kind of issue a worksheet review may catch.
Working With Your Agent to Understand Your Experience Modification Factor
We covered what the experience modification factor is, how the New York Compensation Insurance Rating Board calculates it, and steps that may help you manage it over time. A rising renewal is frustrating, and the factor can feel like a number you have no say in. Reviewing your worksheet and your open claims gives you something to act on.
An owner who studies the worksheet before renewal can walk into that conversation with composure and stability. An owner who waits may find an error only after it has shaped another year of premium.
