Your experience mod is a multiplier on your workers' comp premium, and most Michigan businesses find out theirs is wrong only after paying it for three years.
A 1.25 mod means you pay 25% more than the class rate. A 0.85 means 15% less. The spread between those two on a $60,000 premium is real money.
The part worth understanding: frequency hurts you more than severity. Three $8,000 claims damage your mod more than one $24,000 claim, because the formula weights the number of claims heavily. That changes how you should handle small injuries.
Mods also lag by about three years, which cuts both ways.
