Calculation Methodology ▼
How This Calculator Works
  • Annual Premium = (Annual Payroll / 100) × Base WC Rate × Experience Modification Rate (EMR)
  • PEO Premium = (Annual Payroll / 100) × PEO Pooled Rate × PEO Pooled EMR Factor
  • EMR Projection: Based on NCCI split-point formula. Claims history impacts future EMR over a 3-year rolling window.
  • PEO Discount: PEO rates use a discount factor of 0.56 applied to direct market rates, reflecting pooled buying power.
  • 3-Year Trend: Direct carrier premiums trend at +3%/year (10-year average). PEO premiums trend at +2%/year due to scale.
  • Safety Credit: A 5% premium credit is applied when a formal safety program is in place.

Workers' comp in Indiana: how the system works

In Indiana, workers' comp is sold on the competitive private market, but rates are not set through NCCI. Indiana uses its own independent rating organization, the Indiana Compensation Rating Bureau (ICRB), which files the loss costs and classification rules carriers build their pricing on.

For roofing and construction employers, the class code drives the rate more than anything else: roofing carries some of the highest workers' comp rates of any trade because of fall exposure. Wherever you operate, the experience modification rate is the biggest lever you control, and a cleaner claims history compounds into lower premiums year over year.
