The math behind Private Investigators Professional Liability (E&O) premiums

For Private Investigators, Professional Liability (E&O) premium is calculated per professional FTE + revenue. ISO / carrier-proprietary maintains the rating framework that most carriers use as a starting point, with each carrier layering on its own loss-cost multiplier and credit/debit factors.

What pushes Professional Liability (E&O) premiums up for Private Investigators?

If two Private Investigators have similar revenue but materially different Professional Liability (E&O) premiums, the gap usually comes from one of these factors:

• Pay practices and overtime exposure (FLSA)
• Use of independent contractor vs W-2 classification

Of those, the top driver for most Private Investigators is the first — carriers price the rest as adjustments around it. A clean record on the top factor tends to outweigh imperfect performance on the lower ones.
