In Colorado, workers compensation is priced on your payroll, the kind of work your team does, and your claims history, then quoted by private insurers and the state fund competing for your business. Most small Colorado employers pay a few hundred to a few thousand dollars per employee per year, and rates have been trending down for over a decade.
Who this is for: Colorado owners who want to understand what drives their price and roughly what to budget.
The short version
- Payroll is the base. Premium is calculated per 100 dollars of payroll in each kind of work you do.
- The type of work sets the rate. Your price depends heavily on the category your work falls into for pricing, called the class code.
- Your claims history moves it. A score based on your past claims, called the experience modification rate, raises or lowers your cost.
- Carriers and the state fund compete. Colorado has a competitive market, so insurers and Pinnacol Assurance each set their own final rates, which means shopping pays off.
- Rates are falling. As of mid-2026, Colorado approved an average workers comp loss-cost cut of about 6.9 percent effective January 1, 2026, the twelfth straight annual decrease.
What drives your Colorado price
A handful of factors explain most of the number. Understanding them is how you avoid overpaying.
| Factor | How it affects price |
|---|---|
| Payroll | The base of the calculation; premium runs per 100 dollars of payroll |
| Type of work (the class code) | Riskier trades carry a higher rate than office work |
| Claims history (the experience modification rate) | A record of claims raises your cost; a clean record lowers it |
| How work is split across categories | Miscategorized payroll can overcharge you for years |
| Carrier and market | Each insurer and the state fund set their own rate over a shared baseline |
How Colorado rates are set
Colorado uses the rating bureau NCCI to collect payroll and claims data and file advisory baseline costs, called loss costs, for each kind of work. Those filings go to the Colorado Division of Insurance, part of the Department of Regulatory Agencies, which reviews them with an independent actuary and approves them. Each insurer then applies its own multiplier to the approved loss costs to set the rate it charges, and the state fund, Pinnacol Assurance, competes in the same market. Because carriers set their own multipliers, two insurers can quote the same business quite differently, which is exactly why shopping the market matters. As of mid-2026, the approved loss costs fell about 6.9 percent effective January 1, 2026, continuing a run of twelve straight annual decreases.
Illustrative price ranges
These are rough annual ranges for small Colorado employers, not quotes. Your real number depends on payroll, the exact work, and your claims record.
| Business type | Rough annual workers comp range |
|---|---|
| Office or professional services | $500 to $2,200 |
| Retail store | $1,100 to $4,600 |
| Restaurant or cafe | $2,200 to $9,000 |
| Cleaning or janitorial | $2,600 to $10,000 |
| Landscaping or small contracting | $3,000 to $13,000 |
A Centennial example
Illustrative, not a quote. A Centennial HVAC company with three installers and one office manager gets very different quotes from two carriers because each applies its own multiplier to the same baseline. By splitting the office manager's payroll out of the higher installer category and cleaning up a past claim on the record, the company lowers its price without changing its coverage. We review the categories and the claims score before you buy so you are not overpaying, and we compare private carriers against the state fund. See our workers comp for HVAC contractors page.
Real questions Colorado owners ask
How much does workers comp cost in Colorado?
Most small Colorado employers pay a few hundred to a few thousand dollars per employee per year. The exact price depends on your payroll, the kind of work, and your claims history.
What determines my workers comp rate in Colorado?
Your payroll, the category your work falls into for pricing, and your claims history are the big three. Riskier trades cost more than office work, and a record of claims raises the price.
Why do two Colorado carriers quote such different prices?
Colorado carriers start from a shared baseline but each applies its own multiplier, so the same business can get quite different quotes. That is why shopping several carriers, and the state fund, usually pays off.
Are Colorado workers comp rates going up or down?
Down. As of mid-2026, the approved loss costs fell about 6.9 percent effective January 1, 2026, the twelfth straight annual decrease, subject to review by the state each cycle.
How is the price actually calculated?
Premium runs per 100 dollars of payroll in each kind of work you do, adjusted by your claims-history score. Splitting payroll into the correct categories keeps you from overpaying.
Can I lower my workers comp cost in Colorado?
Often yes. Making sure payroll is in the right categories, improving your claims record, and shopping carriers and the state fund can all bring the price down without cutting your coverage.
Does Colorado have a state fund with set prices?
Colorado has a competitive state fund, Pinnacol Assurance, that competes with private insurers rather than setting one fixed price. Each sets its own rate over a shared baseline, so comparing quotes matters.
Why Colorado owners choose Morrow
- We shop the right market for you. In Colorado you buy workers' comp on the open market, where private insurers compete with the state-chartered fund, Pinnacol Assurance, which by law cannot turn away a Colorado employer, so we can shop your rate across carriers and still have Pinnacol as a guaranteed backstop for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
