Workers’ compensation premium in Utah is built on a simple per-$100-of-payroll formula, then adjusted for your industry risk and claims history. This calculator applies the standard insurance math — manual premium, experience modifier, and schedule credits — so you can estimate annual and monthly cost before requesting quotes.
How it works
Premium starts from payroll and the class base rate:
Manual premium = (Annual payroll ÷ 100) × Class base rate per $100
That figure is then scaled by your experience modifier and any schedule credit:
Modified premium = Manual premium × EMR Net premium = Modified premium × (1 − schedule credit %)
A clerical class might run about $0.10 per $100 of payroll, while roofing can exceed $14 per $100 — the same payroll produces very different premiums depending on the job class.
Utah specifics
- No monopolistic state fund. Utah’s former state fund (now WCF Insurance) was privatised and competes with other carriers. You buy coverage on the open market.
- NCCI class codes and loss costs. Utah uses NCCI loss costs; each carrier applies a loss cost multiplier (LCM) to set its rates, so the rate you enter should be the carrier’s final rate per $100.
- Coverage is mandatory for nearly all employees under the Utah Workers’ Compensation Act, regulated by the Utah Labor Commission.
Worked example
A small Utah office with $250,000 payroll under class 8810 (clerical, ~$0.10/$100) and an EMR of 1.00:
- Manual premium = (250,000 ÷ 100) × 0.10 = $250
- Modified premium = 250 × 1.00 = $250/year
A roofing crew with the same payroll under class 5551 (~$14/$100):
- Manual premium = (250,000 ÷ 100) × 14 = $35,000/year before EMR and credits
Note: These are illustrative rates. Your real Utah premium depends on NCCI loss costs, the carrier’s loss cost multiplier, schedule credits, and assessments. Confirm with a licensed agent.
