Experience modification rate (e-mod)

Published 2026-06-12 · by Brokly

In plain terms: A multiplier on your workers' comp premium that compares your claims history to businesses like yours — better-than-average history discounts the premium; worse raises it.

Why it matters to you

It's the part of the premium you earn over time: safety compounds into cheaper coverage. And once your business is large enough to qualify for one, the mod follows you between insurers — switching carriers doesn't reset a bad year.

Where you’ll see it

On workers' comp quotes and policy paperwork as a factor near 1.0 — below it is a discount, above it a surcharge.
