Inland Marine premium for Private Investigators is calculated per $100 of equipment value, using AAIS / ISO loss costs as the framework. Carriers apply their own loss-cost multiplier, your experience modifier (3-year loss history), and schedule rating (underwriter judgment) to produce the final premium. The audit at policy expiration trues up estimated vs actual exposure.
How is Inland Marine premium calculated for Private Investigators?
Private Investigators pay Inland Marine priced per $100 of equipment value. The rate per unit is the multiplicand; your declared exposure is the multiplier. The product is your base premium before experience-modifier and schedule-rating adjustments.
Understanding the unit lets you ask the right questions at renewal: which exposure changed, what rate is being applied, and where the schedule credits or debits landed. Without that view, the renewal number arrives unexplained.
Why class codes matter for Private Investigators Inland Marine rating
Before any premium is calculated, the underwriter assigns a AAIS / ISO classification to the private investigator. That class determines the base rate per $100 of equipment value and constrains which carriers can quote at all. The class is set based on the predominant operation — what generates the largest share of revenue or payroll.
Mixed operations create classification challenges. A private investigator that does multiple types of work may legitimately fit in two or three different classes, and the choice between them can swing premium 15-30%. Documenting the operation split clearly in the application reduces the risk of mis-classification.
How does schedule rating affect Private Investigators Inland Marine?
Filed schedule-rating plans give underwriters discretion to apply credits or debits to Private Investigators Inland Marine based on operational qualities. The underwriter documents the rationale; the credit or debit applies through the policy term.
Schedule credits add up to real money. A 10% schedule credit on a $15,000 premium is $1,500/year — and that credit usually carries forward at renewal as long as the operational factors that justified it remain.
How three years of claims affect Private Investigators Inland Marine pricing
Private Investigators experience modifiers reflect actual loss performance against expected. The actual is your paid losses (excluding incurred-but-not-paid reserves on open claims); the expected is the class's average loss-cost benchmark.
Improving the mod is a long game. A single clean year reduces the most recent (heaviest-weighted) year's impact. Three consecutive clean years can move a debit mod into credit territory. The patience pays — mod credits compound across multiple policy lines.
The renewal-time math for Private Investigators Inland Marine
At renewal, the Private Investigators Inland Marine premium recalculates with updated inputs: the new base rate (from any approved rate filings), updated exposure (declared or audited), refreshed experience modifier, and any schedule-rating adjustments the underwriter applies.
The combined effect determines the renewal premium. A flat renewal year on a clean account might be ±3-5%. Years with claims or significant exposure changes can move premium ±20-40% or more.
Why two carriers price the same Private Investigators risk differently on Inland Marine
Two carriers can quote the same private investigator on Inland Marine and produce premiums that differ 15-30%. The difference comes from carrier-specific loss-cost multipliers (each carrier's adjustment to the AAIS / ISO base rate), schedule-rating philosophy, and target loss ratios for the segment.
Some carriers actively pursue workforce provider business and price aggressively for it; others see the segment as marginal and price defensively. Knowing which carriers are currently in either bucket is the broker's job — and it materially affects which markets to target.
Where Private Investigators accounts most often get over-rated on Inland Marine
Three methodology errors account for most Private Investigators Inland Marine overpayments: mis-classification (a class assignment that doesn't match the predominant operation), over-stated exposure (more revenue/payroll declared than reality), and unclaimed credits (schedule rating left on the table).
The fix is process, not policy. Pre-renewal audits catch these errors before they get baked into another year of pricing.

Filed plans typically allow ±15-25%. Documented safety, claims-free history, and operational quality earn credits; minor concerns trigger debits. Schedule rating is real money — a 10% credit on a $15K premium is $1,500/year.
Each carrier has its own loss-cost multiplier, schedule-rating philosophy, and target loss ratio for workforce provider. Spreads of 15-30% between cheapest and most expensive are normal.
Three years. Claims roll out of the experience-mod window on their 3rd anniversary. After that, the claim no longer directly affects the mod (though it may still be in the loss history carriers review).
The unit your premium is rated against — for this coverage, that is per $100 of equipment value. Higher exposure means higher base premium; lower exposure means lower base premium, all else equal.
