The Workers' Comp Experience Mod Multi-Unit Franchisees Never Audit

Two multi-unit franchisees each run four locations. Operator A owns 100 percent of every LLC in the group. Operator B brought in a local partner at two of the four stores, each holding 55 percent, dropping Operator B's stake below the ownership threshold that ties workers' comp experience together. When a line cook at one of Operator A's stores tears a rotator cuff and the claim reserves land at $34,000, the mod moves at all four of his locations before the next renewal. When the same injury happens at one of Operator B's minority-owned stores, only that unit's premium changes. Same injury, same claim size, same carrier class code, and a completely different bill, because the workers' comp experience mod aggregates across commonly owned locations, not across a brand or a menu.

What a workers' comp experience mod actually measures

The experience modification rate, or e-mod, is a multiplier the National Council on Compensation Insurance (NCCI) or a state rating bureau applies to a business's base workers' comp premium. A mod of 1.00 means a business is filing claims at exactly the industry average for its size and classification code. Below 1.00 is a credit; above 1.00 is a debit, and every point above 1.00 adds directly to the premium a franchisee pays regardless of what the base rate table says.

The mod isn't calculated off last year's claims. NCCI uses a three-year window that excludes the most recent policy year, so an e-mod effective in 2026 is built from claims filed across 2022, 2023, and 2024. That lag means a location that cleaned up its safety record eighteen months ago is still paying for it, and a location with a rough 2023 won't feel the full premium hit until the mod catches up with the calendar.

Why frequency beats severity in the formula

NCCI splits every claim into a primary loss and an excess loss, and the primary portion, capped at roughly $17,000 to $19,000 depending on the state and year, carries far more weight in the mod formula than the excess portion above that cap. The practical effect: six small claims totaling $20,000 over three years will move a location's mod more than one $20,000 claim in the same window. A franchise unit with a habit of minor slip-and-falls or repetitive strain claims is a worse mod risk than a unit with one bad year and an otherwise clean record, even if the total dollars paid out are identical.

That formula rewards claim frequency management over claim severity management, which is the opposite of how most franchise operators think about safety. A single serious injury gets a root-cause review. A pattern of minor claims across a shift schedule rarely gets the same scrutiny, and it's the pattern that's actually driving the number.

The ownership threshold that decides what your workers' comp experience mod combines

NCCI's Experience Rating Plan Manual, Rule 3.D, combines the workers' comp experience of any legal entities with more than 50 percent common ownership, even when each entity holds a separate policy and a separate FEIN. Ownership is measured by voting stock, membership interest, or board control, whichever applies to the entity type, and the rule chains: if Entity A owns a majority of Entity B, which owns a majority of Entity C, all three combine regardless of how many entities sit in between.

For a franchisee, this means the LLC-per-location structure a franchise attorney sets up for liability protection does nothing to separate insurance risk unless the ownership split is deliberately structured at or below 50 percent in at least one entity. Most multi-unit franchisees never structure for that threshold because nobody explains that the mod, not just the liability shield, depends on it.

What a bad mod actually costs

Run the math on a mid-size location. Restaurant workers' comp rates average $1.06 per $100 of payroll under NCCI class code 9082; retail runs closer to $1.66 per $100 of payroll. A location with $2 million in annual payroll at the retail rate carries a base premium of roughly $33,200 before the mod is applied. At a 0.85 mod, that location pays about $28,200. At a 1.25 mod, driven by claim frequency at a sibling location under the same ownership, the same store pays roughly $41,500 for identical staffing and identical sales. That is a $13,300 swing attributable entirely to claims filed somewhere else in the network.

Multiply that gap across every combined location and the number stops being a rounding error. A ten-unit group carrying a 1.25 mod instead of a 0.85 mod on $2 million payroll per location is paying more than $130,000 a year in premium that traces back to claim frequency at a handful of stores, not the group's overall safety record. The average cost of a single workers' comp claim was $47,316 for accidents occurring in 2022 and 2023, according to the National Safety Council's Injury Facts data, sourced from NCCI. One bad claim year at one location is enough to move a group mod for three years.

Where the mod audit actually needs to happen

Most franchise finance teams review the renewal premium once a year and treat the mod as a number the broker hands them. The audit that actually protects the group happens earlier, at three points: when a new unit is added to an existing ownership entity instead of a new one, when a location is sold or a partner buys in, and when the experience rating worksheet arrives each year showing which specific claims are driving the primary loss total.

Pull the worksheet and check three things. First, confirm which entities are combined and whether that list matches the current cap table, because ownership changes don't automatically get reported to the rating bureau. Second, identify which location and which claim type is contributing the largest primary loss, since that is the location that needs a claims-frequency intervention, not a group-wide safety memo. Third, check the classification codes assigned to each location against the actual work being performed. Misclassified payroll, a kitchen crew coded under a lower-risk clerical code, for example, understates the expected loss baseline and can inflate the mod even when claims are average.

The number that follows the group, not the location

An experience mod is one of the few operating numbers in a franchise system that ignores brand standards entirely and tracks ownership structure instead. A location can run a clean kitchen, pass every health inspection, and still carry a premium penalty because a sibling store two states away had a bad string of claims and both entities sit under the same majority owner. Revscale's franchise data infrastructure surfaces claims and compliance signals at the location level specifically so operators can see which unit is driving group-wide costs before the renewal notice does the explaining for them.

The fix is not complicated once the mechanism is visible. Franchisees adding units through new entities should decide the ownership split before the first employee is hired, not after the second claim arrives. The workers' comp experience mod is calculated off decisions made at formation, not off decisions made during the next renewal cycle, and by the time the worksheet shows up, the only thing left to manage is which claims get filed next.
