QUICK ANSWER

Business Interruption premium for Property Restoration Companies is calculated <strong>per $1,000 of insured income</strong>, using 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.

The unit of exposure behind Property Restoration Companies Business Interruption pricing

For Property Restoration Companies, Business Interruption premium is calculated per $1,000 of insured income. That is the unit of exposure carriers use to scale premium against the size of the operation. ISO maintains the rating framework most carriers start with, and each insurer layers on its own loss-cost multiplier.

Why the unit matters: a property restoration company with twice the exposure unit will pay roughly twice the base premium, all else equal. If you understand the rating basis, you can predict how operational changes (revenue growth, headcount additions, fleet expansion) will move premium at renewal.

How does the Business Interruption audit work for Property Restoration Companies?

The audit on Business Interruption for Property Restoration Companies reconciles estimated exposure (used to set the policy premium) against actual exposure (what really happened during the policy period). The auditor pulls payroll records, tax filings, vehicle inventories, or whatever the rating basis requires.

Audits are not optional. Refusing to provide audit data typically results in the carrier applying maximum exposure assumptions and billing the difference — a much worse outcome than cooperating with a clean audit.

How a typical property restoration company Business Interruption premium adds up

A property restoration company can model their own Business Interruption premium movement at renewal by understanding the five factors that produce it. Base rate × exposure × experience modifier × schedule rating × surcharges = premium.

What this means in practice: if your exposure (revenue, payroll, etc.) drops 10%, expect roughly a 10% reduction in base premium before adjustments. If your experience modifier improves from 1.05 to 0.95, that's a 9.5% credit on top. The math is layered but predictable.

Property Restoration Companies experience-mod mechanics

The experience modifier compares a property restoration company's actual three-year paid losses to the expected losses for the class. A modifier of 1.00 is neutral; below 1.00 is a credit (better than class average); above 1.00 is a debit (worse than class average).

The mod multiplies through the base rate, so its impact is direct. A mod of 0.90 produces a 10% premium reduction; a mod of 1.20 produces a 20% premium increase. For Property Restoration Companies, the mod is one of the largest single inputs to the final premium.

How Property Restoration Companies Business Interruption pricing recalculates at renewal

Renewal pricing for Property Restoration Companies Business Interruption is not a static carry-forward. Every input gets refreshed: rates from state filings, exposure from declarations or audits, experience modifier from the rolling three-year loss window, and underwriter judgment via schedule rating.

Understanding which input moved is the key to understanding the renewal number. A 12% renewal increase could be all rate (state-level), all exposure (your growth), all experience mod (a claim), or a combination. The renewal proposal should break down which lever moved.

Carrier-to-carrier rating variation on Property Restoration Companies Business Interruption

Two carriers can quote the same property restoration company on Business Interruption and produce premiums that differ 15-30%. The difference comes from carrier-specific loss-cost multipliers (each carrier's adjustment to the ISO base rate), schedule-rating philosophy, and target loss ratios for the segment.

Some carriers actively pursue specialty trade 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.

Hidden methodology errors on Property Restoration Companies Business Interruption

The most common reasons Property Restoration Companies overpay on Business Interruption are methodology errors, not bad rates. Top three by frequency: wrong class code (15-30% overpricing), wrong exposure declaration (auditable, but only at year-end), and missed schedule-rating credits the underwriter could have applied if asked.

None of these require operational changes to fix — just attention to the methodology paper trail. A 30-minute audit of the current binder against last year's typically surfaces at least one correctable error.
