Workers Comp Cost Per Employee: Why the Question Itself Misleads You

Asking about workers comp cost per employee sends you looking for the wrong number.

In most states, workers compensation premiums are calculated as a percentage of payroll, set by your classification and adjusted for your claims history. Two employees sitting in the same office can generate wildly different premium costs if one earns $35,000 and the other earns $95,000. Searching for a single dollar figure per person gives you a false sense of what you actually owe.

The Real Formula Behind Workers Comp Pricing

In Texas, the premium starts with one equation: (annual payroll / 100) x class code rate x experience modifier, if one applies. New York’s State Insurance Fund says these rates are usually per $100 of payroll, with the rate determined by job classification.

When someone quotes you a “per employee” figure without knowing your classification, that number is meaningless.

The tradeoff with rate-per-$100 pricing is that your premium rises automatically as payroll grows. Hiring a new employee or giving raises increases your insurance cost even if your risk profile stays identical. Budget for this before the premium audit your carrier runs after the policy term ends.

Washington is the exception: its Department of Labor & Industries (L&I) charges an amount per hour worked, so when wages go up, the rate paid stays the same.

Pay-as-you-go billing through payroll integration (offered by carriers working with payroll providers like Gusto) changes the timing. Instead of estimating annual payroll up front, you pay premiums each pay period based on actual wages reported.

Class Codes Determine Your Starting Price

In Texas, clerical code 8810 applies only to employees doing office work exclusively. Listing a field technician under clerical code 8810 does not save money. The audit after the policy term can catch the discrepancy, and your premium for the audited period can increase.

In Texas, an employee who splits time between operations in more than one classification has their entire payroll assigned to the highest rated one. Construction is one of the exceptions, where Texas allows an individual employee’s payroll to be divided, but only with accurate records of the work each employee performed.

Where splitting is allowed, Texas does not permit an estimated or percentage allocation of payroll.

Your Experience Mod Multiplies or Shrinks the Bill

The experience modification rate (EMR) is a multiplier applied to your base premium. In Washington, L&I sets the factor each year from a three year experience period. Losses below what L&I expects for your risk class bring a factor below 1.0 the next year. Losses above it bring a factor above 1.0, and a claim affects your premiums for three calendar years.

Washington generally limits the change in a business’s factor to 25% in one year, up or down. Even a business with no claims counting against its factor can see its rate rise when the rate for its risk class goes up, according to L&I.

Some states skip experience rating for employers below a premium threshold. Washington uses no threshold: a business that reported worker hours during the three year experience period is experience rated.

State Rates Vary More Than You Expect

Workers compensation is regulated at the state level, and rate differences are significant. Four states run their own workers’ comp funds: North Dakota, Ohio, Washington and Wyoming. Who must buy from each fund differs by state, and the workers comp guide explains the rules for each. In Washington, workers pay on average about 24% of the premium, according to L&I, and about the same share under its proposed 2027 rates.

Oregon’s Department of Consumer and Business Services ranks premium rates in every state and the District of Columbia. Its 2024 index put New York at $1.98, or 182% of the study median, and Oregon at $0.89, or 82%. When budgeting for a new location or remote employee, check the destination state’s filed rates before assuming your current cost per worker translates.

What to Gather Before You Ask for a Quote

Start with the right inputs instead of searching for averages that never match your business.

Pull your current experience modification rate. Verify your class codes against the class code descriptions in your state’s workers comp manual. Gather your projected annual payroll broken down by classification.

Outside the four state fund states, request quotes from at least two carriers. Compare the rate per $100 at each classification, not just the total premium, so you can see exactly where the pricing differs.

Employers using a professional employer organization should request a separate workers comp rate breakdown to confirm bundled pricing is competitive. If your EMR is above 1.0, ask your broker about a formal return-to-work program. In Washington, L&I says helping injured workers return to work quickly and safely does have a return on investment. Check your total insurance costs to confirm you are not overpaying.
