Business Interruption Insurance for US Businesses
Business interruption insurance, also called business income insurance, replaces the revenue your business loses when a covered event forces you to suspend or reduce operations. Commercial property insurance pays to repair or replace the physical damage. Business interruption coverage pays the bills while that repair is happening.
What Business Interruption Insurance Covers
The policy replaces what your business would have earned if the covered event hadn't happened, and it covers the ongoing fixed expenses you can't stop paying during the closure. Both matter.
Lost Net Income
Replaces the revenue your business would have earned during the closure period, based on your documented financials.
Continuing Fixed Expenses
Covers rent, mortgage, loan repayments, utilities, and other obligations that don’t stop during a closure.

What Triggers a Business Interruption Claim
This is the part that catches business owners off guard more than any other aspect of BI coverage. Business interruption insurance doesn't pay out for loss of income on its own. There has to be direct physical damage to covered property from a covered peril first. The income loss flows from the physical damage - it doesn't stand alone.
Covered
A fire destroys your production floor and forces a three-month closure
Not covered
A power outage shuts you down for four days without physically damaging anything
Not covered
A government-ordered closure without adjacent physical damage
Not covered
A slow quarter because foot traffic dropped
The underlying commercial property coverage also matters. Business interruption only responds to the perils covered in your property policy. If your property policy excludes floods and your building floods, your BI coverage won't respond either. The two policies move together - which is why it's worth reviewing both at the same time.
What Business Interruption Insurance Does Not Cover
Knowing the exclusions in advance is considerably more useful than discovering them during a claim.
Floods and earthquakes
Excluded from your underlying property policy by default, which means BI won’t respond either. Separate endorsements are required.
Pandemics and communicable disease
Most standard BI policies exclude losses from disease, epidemic, or pandemic. Talk to a broker about specialty market options if your operation has specific exposure.
Government shutdowns without physical damage
A government order to close without a covered physical damage event nearby doesn’t trigger standard BI. Civil authority coverage requires proximate physical damage.
Undocumented income
BI claims are calculated from your documented financial records. Revenue that isn’t in your books can’t be claimed.
Utility interruptions
A power outage that shuts you down doesn’t trigger standard BI unless physical damage to covered property caused it. Off-premises utility interruption is a separate endorsement.
Cyber incidents
A cyberattack that takes your systems offline without physical property damage falls outside standard BI. Cyber coverage handles that exposure separately.
Normal business slowdowns
Market downturns, lost contracts, or seasonal revenue drops aren’t covered. BI responds to physical events, not business performance.
Third-party claims arising from your closure - a customer suing because you couldn't fulfill an order - fall under general liability, not business interruption.
Timing Mechanics
How the Waiting Period and Restoration Period Work
Two timing mechanics in every BI policy determine when coverage starts and when it ends. Both are negotiable at placement and both affect your real-world protection significantly.
Waiting Period
The time between when the physical damage occurs and when BI benefits begin. Most standard policies set this at 48 to 72 hours. It’s designed to filter out very short disruptions. For operations where even a day of closure means significant revenue loss, a shorter waiting period is worth requesting.
Restoration Period
How long coverage runs. The policy pays until your business is restored to its pre-loss operating condition, typically capped at 12 months. A manufacturer waiting on custom equipment with a six-month lead time, or a restaurant facing a full structural rebuild, can easily run past 12 months.
Extended Period of Indemnity
An endorsement that extends BI coverage beyond the restoration period to account for the ramp-up time after reopening. A business that closes for six months doesn’t return to full revenue on day one. The extended indemnity period - typically 30, 60, or 90 additional days - covers that lag.
Contingent Business Interruption
Standard BI covers income loss when your own property is damaged. Contingent business interruption (CBI) covers income loss when a key supplier, vendor, or customer suffers physical damage that prevents them from operating, and that interruption flows through to your business.
Your building is fine. Your equipment is fine. But your primary supplier's factory burned down. That's a CBI loss.
What triggers it
Business Interruption (BI)
Physical damage to your own covered property
Contingent BI (CBI)
Physical damage to a dependent third-party property (supplier, customer, or key partner)
What it pays
Business Interruption (BI)
Lost income and fixed expenses during your closure or reduced operations
Contingent BI (CBI)
Lost income and extra expenses resulting from the dependent property’s disruption
Who needs it
Business Interruption (BI)
Most businesses with a physical location or equipment-dependent operations
Contingent BI (CBI)
Manufacturers, retailers, or businesses that depend on a small number of critical suppliers or customers
Key limitations
Business Interruption (BI)
Excludes pandemics, floods/earthquakes (unless underlying property covers them), utility outages without physical damage
Contingent BI (CBI)
Often limited to first-tier suppliers; coverage territory may not extend internationally; requires physical damage
| Factor | Business Interruption (BI) | Contingent BI (CBI) |
|---|---|---|
| What triggers it | Physical damage to your own covered property | Physical damage to a dependent third-party property (supplier, customer, or key partner) |
| What it pays | Lost income and fixed expenses during your closure or reduced operations | Lost income and extra expenses resulting from the dependent property’s disruption |
| Who needs it | Most businesses with a physical location or equipment-dependent operations | Manufacturers, retailers, or businesses that depend on a small number of critical suppliers or customers |
| Key limitations | Excludes pandemics, floods/earthquakes (unless underlying property covers them), utility outages without physical damage | Often limited to first-tier suppliers; coverage territory may not extend internationally; requires physical damage |
For businesses with concentrated supply chains - one or two critical vendors who can't easily be replaced - named CBI coverage is worth structuring properly.
Coverage Calculation
How to Calculate How Much Coverage You Need
The most common BI mistake isn't buying the wrong policy - it's setting the limit too low. Businesses often anchor on last year's net profit and call it done. That misses the fixed expenses that keep running during a closure.
12-month gross income figure
The base number for income replacement calculation - use documented financials, not estimates.
Fixed expenses that continue during closure
Rent, loan repayments, payroll for retained staff, taxes - these need to be in your limit, not just net profit.
Realistic restoration period
How long would it actually take to rebuild, restock, and reopen? Factor in equipment lead times and permitting.
Extra expense exposure
Cost of renting temporary space, expediting equipment, or outsourcing operations during repairs.
Extended indemnity period
How long before you’d be back to pre-loss revenue after reopening? That lag is insurable.
CBI exposure
Do you rely on one or two critical suppliers or customers? If so, their disruption is your exposure.
A rough starting formula: take your 12-month gross income, add your fixed operating expenses for the same period, and multiply by the fraction of a year your realistic worst-case restoration takes. That gives you a floor. The right number depends on your specific operation.

How Rosella Places Business Interruption Coverage
Most brokers skip the income documentation conversation and just carry forward whatever the prior year's limits were. Limits set without reviewing actual financials are often the reason a BI claim comes up short.
We review your income documentation first
Before we submit, we review your financials, work through a realistic restoration period for your type of operation, and flag whether your supply chain makes CBI worth adding.
We place BI alongside your property coverage
BI isn’t sold as a standalone policy. It’s placed alongside commercial property or inside a BOP. The property placement decision affects what BI will and won’t respond to - we handle both together.
