Coverage for lost income after an insured property loss disrupts operations.
Business interruption is coverage for lost business income and certain continuing expenses when an insured property loss disrupts normal operations.
A business can survive physical damage and still fail because revenue stops while payroll, rent, debt service, and other fixed costs continue. This coverage matters because the operational shutdown is often the larger problem.
Business-interruption wording commonly sits beside commercial property rather than standing alone. The usual logic is:
Waiting periods, restoration periods, extra expense, and valuation methods are often central to the claim.
That structure matters because business interruption is usually downstream of the property trigger. The file does not start with “how much revenue was lost?” It starts with “was there a covered property event, and did that event actually interrupt operations?” Only after that does the claim move into financial measurement.
| Term | Main trigger logic | Main question it answers |
|---|---|---|
| Business interruption | Covered loss disrupts the insured business’s own operations | Is there an interruption claim at all after the triggering event? |
| Business Income | Sits inside interruption wording | How is the lost income and continuing-expense component measured? |
| Extra Expense | Additional spend after the covered interruption | What extra costs were reasonably incurred to reduce downtime? |
| Contingent Business Interruption | Damage happens at a supplier, customer, or other outside dependency | Did someone else’s damaged property interrupt this business? |
| Civil Authority Coverage | Access is blocked by authority action tied to a covered event | Did official closure or restricted access interrupt the business? |
| Question | Why it matters |
|---|---|
| Was there insured physical loss or damage? | Business interruption usually depends on a covered property trigger. |
| Did the event actually disrupt operations? | A covered fire or water loss does not create an income claim if the business kept operating normally. |
| What would the business likely have earned but for the loss? | The claim depends on evidence, not guesswork. |
| What continuing expenses still had to be paid? | Payroll, rent, debt service, and similar costs often remain relevant even when revenue falls. |
| How long did the covered interruption last? | The answer is shaped by the policy’s restoration period, waiting period, and mitigation facts. |
A fire damages a restaurant kitchen and the business closes for two months while repairs are completed. The property policy addresses the damaged equipment and building elements, while business-interruption coverage may address lost income and certain ongoing operating costs during the shutdown.
In a real file, the claim may also have to separate sales the restaurant truly lost from sales it recovered later, document payroll that continued during the closure, and explain whether the restaurant could have operated partially through delivery, temporary premises, or limited service.
Business interruption is not the same as commercial property. Property coverage pays for physical damage to insured assets. Business interruption responds to the economic consequences of the shutdown caused by that physical loss.
It is also different from commercial general liability, which deals with liability to others rather than the insured business’s own lost income.
It is also broader than business income alone. Business interruption is the wider coverage idea, while business income and extra expense are major components inside that structure.
Another common mistake is assuming every slowdown qualifies. Many businesses suffer lower revenue for market reasons, staffing issues, or supplier problems that are not business-interruption claims unless the wording extends to those situations.
It is also a mistake to use business interruption as a catch-all label for every income-loss extension. The real file may turn on whether the loss happened at the insured site, at a dependent property, or because access was blocked by civil authority.
Not every drop in revenue is a business-interruption claim. The wording usually requires a covered trigger, a defined restoration period, and supportable income evidence.
