How PEO Workers' Comp Rates Work
The Structure Behind Your Workers Comp Rate
PEO workers comp rates are built from filed base rates, experience modifiers, group rating discounts, and PEO markups. Understanding how these pieces fit together tells you why your rate is what it is, why different PEOs quote different rates, and how to get the lowest possible rate for your business.

Key Workers Comp Factors
Filed Base Rate
Each class code has a base rate filed with the state. This is the starting point before any discounts or modifiers are applied.
Experience Modifier
Your EMOD scales the base rate up or down based on your claims history versus your industry average.
Group Rating Discount
PEOs pool your payroll to earn group rating discounts that lower your effective rate below the filed base rate.
Schedule Credits
Credits for safety programs, drug free workplaces, or return to work programs can reduce your rate further.
PEO Markup
Some PEOs add a markup over the pure cost. This raises your effective rate. Others pass through at cost.
Class Code Accuracy
Accurate class code assignment ensures you pay the right rate for each role. Misclassification leads to wrong rates and audit adjustments.
The 4 Layers of a PEO Workers Comp Rate
Your final PEO workers comp rate is built from four layers. First is the filed base rate, which is set by the state for each class code. Second is the experience modifier, which scales the base rate up or down. Third is the group rating discount, which the PEO earns by pooling your payroll. Fourth is the PEO markup, which some PEOs add over the pure cost. Your final rate is the result of all four layers combined.
- Filed base rate set by the state for each class code
- Experience modifier scales the base rate up or down
- Group rating discount from PEO payroll pooling
- Schedule credits for safety programs
- PEO markup added by some PEOs
- Your final rate is all four layers combined
Why Different PEOs Quote Different Rates
The filed base rate and your EMOD are the same regardless of which PEO you use. What differs is the group rating discount and the PEO markup. Each PEO has its own group rating arrangement with its carrier, which means different PEOs earn different discounts for the same class codes. And each PEO has its own markup policy. This is why the same business gets different rates from different PEOs. A broker compares the final rate across multiple PEOs.
How to Get the Lowest PEO Workers Comp Rate
To get the lowest rate, you need to optimize the layers you can control. Improve your EMOD through safety programs. Ensure your class codes are accurate. Choose a PEO with a strong group rating arrangement for your industry. And choose a PEO that passes workers comp through at cost instead of marking it up. A broker shops your risk across multiple PEOs to find the one with the best combination of group discount and low or no markup.
