How Workers Comp Premiums Are Calculated
Workers comp premium has a simple formula: (Estimated Annual Payroll ÷ 100) × Class Code Rate × Experience Modification Rate. Each variable is worth understanding because each one is something you can influence.
The base rate is tied to your NCCI class code — the four-digit code assigned to your type of work. Roofing (5551) consistently carries the highest rates in the industry, often $8 to $22 per $100 of payroll. Electrical work (5190) runs $3 to $6. Drywall and carpentry fall in the middle. The rate reflects the statistical frequency and severity of injuries in that trade nationwide.
Once you have the base rate, your EMR is applied as a multiplier. A 0.85 EMR reduces your premium by 15%. A 1.25 EMR increases it by 25%. For a contractor with $500,000 in payroll at a $4.00 rate, the difference between a 0.85 and 1.25 EMR is $8,000 per year.
Typical Workers Comp Costs by Trade
Roofing contractors consistently pay the highest rates — $8 to $22 per $100 of payroll depending on state and carrier. A roofing company with $300,000 in payroll could pay anywhere from $24,000 to $66,000 annually before EMR adjustments. That’s why a clean loss history matters so much for high-risk trades.
Electrical contractors typically pay $3 to $6 per $100. Plumbers run $2.50 to $5.00. Carpenters doing new construction pay $4 to $9. Interior trades like painting and drywall fall in the $2 to $4.50 range. Landscaping is often the lowest trade-adjacent category at $2 to $4.
Ghost policies for sole proprietors who exclude themselves often have minimum premiums of $500 to $1,500 annually depending on state. The owner is excluded from payroll, so the premium is calculated on the minimum reportable payroll floor — not your actual earnings.
What Drives Your EMR Up or Down
Your experience modification rate is calculated by the NCCI (or your state’s rating bureau) using claims data from the three policy years that ended two years prior to your current policy. So your 2025 policy uses data from 2021, 2022, and 2023.
Frequency of claims matters more than severity up to a point. The EMR formula uses primary losses (the first portion of each claim, typically up to $18,000) at full weight and excess losses at reduced weight. That means three small claims can hurt your EMR more than one large claim.
To reduce your EMR, focus on: implementing a return-to-work program, disputing fraudulent claims, reviewing your unit statistical report for errors, and building a genuine safety culture. Even one year of zero or minimal claims starts shifting the formula in your favor.
Pay-As-You-Go vs. Standard Billing
Standard workers comp billing requires you to estimate your annual payroll at inception and pay a deposit premium. At year-end, the carrier audits your actual payroll. If you underestimated, you receive an audit bill. If you overestimated, you get a refund. For contractors with seasonal crews or variable workloads, the audit can be a painful surprise.
Pay-as-you-go billing integrates with your payroll provider and calculates premium each pay cycle based on actual wages paid. There’s no deposit, no estimate, and no surprise audit — because the premium tracks actual payroll in real time.
The tradeoff is that pay-as-you-go typically requires a payroll service integration and sometimes carries a small processing fee. For most contractors, eliminating the audit risk far outweighs the nominal cost.
How to Reduce Your Workers Comp Premium
Request a classification review. If any employees are doing tasks safer than their current class code suggests, a reclassification can immediately reduce your rate. A carpenter who has moved to supervisory work might qualify for a lower-rated code.
Implement formal safety programs. Many carriers offer safety credits or schedule credits for documented programs — OSHA 10/30 certifications, pre-employment drug screening, toolbox talks, and written safety policies all signal lower risk.
Contest questionable claims. Claims that were filed fraudulently or that shouldn’t count as occupational injuries can be contested through your carrier. Successfully closing or reducing a claim lowers its impact on your EMR.
Shop at renewal. Your carrier is not your only option. Independent agents — like Trade Safe Insurance — can compare quotes from dozens of carriers at renewal and often find meaningful rate differences for the same coverage.

Frequently Asked Questions
What is the average workers comp cost for a contractor? +
It varies widely by trade. Most contractors pay between $2 and $10 per $100 of payroll. High-risk trades like roofing pay $8 to $22. Low-risk interior trades may pay $2 to $3.
How does the experience mod affect my premium? +
The EMR is a multiplier applied to your base premium. A 0.85 EMR saves 15%; a 1.20 EMR adds 20% to your total premium.
What is a minimum premium on a workers comp policy? +
Most carriers have a minimum annual premium regardless of payroll — often $500 to $1,500. This applies even to ghost policies with no actual payroll.
Can I lower my workers comp premium mid-policy? +
Generally no mid-term, but documenting payroll corrections, reclassifying employees, or disputing claims can affect the audit or future renewals.
Why did my renewal rate increase? +
Increases are usually driven by a rising EMR from prior claims, class code rate increases filed with the state, or loss of carrier credits. We review all three at renewal.
Does workers comp go up after a claim? +
Not immediately — claims take two years to enter your EMR calculation. But yes, a significant claim will raise your EMR in future policy years, increasing premiums.
