The math
What your mod costs you, in dollars
Your X-Mod is a multiplier on your whole workers' comp premium. A 1.00 is average. A 1.30 means you pay roughly 30% more than an average employer with the same payroll and type of work.
Here's the part most owners miss: each new mod is built from about three years of claims history. So one rough year doesn't cost you once — it shows up in three renewals in a row before it rolls off.
| Employer at 1.00 mod | $50,000 / yr |
|---|---|
| Employer at 1.30 mod | $65,000 / yr |
| Extra cost each year | +$15,000 |
$50,000 × 1.30 = $65,000 · $65,000 − $50,000 = $15,000
One bad year, three renewals
Renewal 1
+$15,000
Renewal 2
+$15,000
Renewal 3
+$15,000
Total extra cost from one bad year
$45,000

FAQ
Common questions
Plain-English answers about X-Mods and how CompCost IQ works.
Methodology
How the estimate works
Your X-Mod multiplies the portion of your premium it applies to. If everything else stays equal, premium moves in proportion to the X-Mod. See "The math" above for a worked example.
Full methodology- Estimated new premium = current premium × (new X-Mod ÷ current X-Mod).
- All other rating factors (payroll, class codes, carrier rates, schedule credits/debits, fees) are assumed unchanged unless you enter an assumption.
- Forecast payroll growth and rate changes are your own assumptions and compound annually from today's premium.
- Future X-Mods default to your new X-Mod unless you enter a value. CompCost IQ does not predict X-Mods.
- Higher- and lower-cost scenarios shift your assumed rate change up and down by the scenario spread.
