Workers' Comp Premium Estimator
Estimate what workers' comp will cost per trade, and check whether you even have to cover yourself.
Sound familiar?
- “You're bidding a job and need a rough number for workers' comp before you can price the labor.”
- “You don't know your trade's class code or how the premium is even worked out.”
- “You're a sole proprietor and you're not sure if you have to carry comp on yourself at all.”
What this tool does
Pick your trade to get its NCCI class code, enter your annual payroll and your rate per $100, and see an estimated premium. It also flags whether your state runs a monopolistic fund and whether you have to cover yourself as an owner.

What the law actually says
- •Workers' comp premium is based on payroll: your rate per $100 of payroll, times your payroll, times your experience modifier (e-mod). Each trade has its own NCCI class code and rate.
- •Most states require coverage once you have employees. Four states (Ohio, Washington, Wyoming, North Dakota) run monopolistic funds you must buy from directly.
- •Whether you must cover yourself as an owner varies: Texas comp is fully elective, California requires it even for sole proprietors, and most states let officers opt out.
