Business Interruption (BI) insurance replaces the income your business loses while it's shut down after a covered property loss — and keeps paying continuing expenses like rent and payroll. It typically costs $40-$130/month and is usually a coverage part inside your Commercial Property policy or BOP, not a standalone policy. The critical rule — the one that surprised thousands of businesses in 2020 — is that BI must follow a covered physical loss (fire, storm, etc.); a shutdown with no physical damage generally does not trigger it. Most policies pay for a restoration period of up to 12 months after a short waiting period (commonly 48-72 hours).
Property insurance rebuilds your building; Business Interruption keeps your business alive while it's being rebuilt. It's the coverage that pays net income, payroll, rent, loan payments, and relocation costs during the shutdown — and it's one of the most valuable and most misunderstood coverages small businesses buy.

Cost and period figures are typical-case and vary by revenue, policy, and carrier.

What Business Interruption covers
When a covered event forces your business to suspend operations, BI replaces the financial position you would have been in had the loss not occurred:
- Net income — the profit you would have earned during the shutdown.
- Continuing operating expenses — rent/lease, loan payments, and other fixed costs that don't stop.
- Payroll — to retain employees during the closure (often an option to include/exclude, or a limited period).
- Temporary relocation — the cost of moving to and operating from a temporary site.
- Extra Expense — the added costs to speed reopening (expedited shipping, temporary equipment, overtime).
The trigger: covered physical loss
This is the single most important thing to understand about BI. Standard Business Interruption is triggered only by a direct physical loss of or damage to covered property from a covered peril (fire, windstorm, etc.). A shutdown without physical damage — a pandemic order, a nearby event, a supplier's failure — generally does not trigger standard BI. This is why so many 2020 pandemic-closure claims were denied and litigated.
Who needs it & how much
Almost every business with a physical location, inventory, or equipment needs BI — it's often the difference between reopening and closing for good after a fire or storm. To size the limit, calculate the net income + continuing expenses you'd need to survive a realistic worst-case restoration period (how long would it take to rebuild and reopen?). Under-estimating the restoration period is the most common BI mistake.
How much does it cost?
Because BI is usually a coverage part of a property policy or BOP rather than standalone, the incremental cost is modest — typically $40-$130/month, scaling with your revenue and the coverage limit/period you select. The drivers:
- Business income & revenue — the primary rating factor (BI replaces lost revenue).
- Restoration period / indemnity period — longer coverage periods cost more.
- Industry & rebuild complexity — how long realistic recovery takes.
- Waiting period & endorsements — added perils (utility, civil authority, contingent BI) raise premium.

BI vs Extra Expense vs Contingent BI
- Business Interruption — replaces lost income during your own shutdown after a covered physical loss.
- Extra Expense — pays the added costs to keep operating or reopen faster; often bundled with BI.
- Contingent Business Interruption — covers income lost when a key supplier or customer suffers a covered loss and disrupts your operations.
- Civil Authority — covers a limited period when a government order (following nearby covered damage) blocks access to your premises.
What's NOT covered (key exclusions)
- Shutdowns with no physical damage — pandemics, market downturns, and voluntary closures (absent specific endorsements).
- Excluded property perils — flood and earthquake are excluded unless separately covered (as with property).
- Losses beyond the restoration/indemnity period — coverage ends when the period cap is reached.
- Uncovered utility/off-premises failures — unless a Utility Services or Contingent BI endorsement is added.
- Loss of market / permanent customer loss — BI covers the restoration period, not lost future business.
Frequently Asked Questions
Does business interruption cover COVID-style shutdowns?
Generally no. Standard Business Interruption requires a covered physical loss (fire, storm, etc.) to trigger. A closure with no physical damage — a pandemic order, market downturn, or voluntary shutdown — typically isn't covered, which is why most 2020 pandemic claims were denied. If that's your concern, you need specific endorsements (Civil Authority, Utility Services, Contingent BI), and even those are limited.
Is business interruption a separate policy?
Usually not — it's a coverage part inside a Commercial Property policy or a BOP. That's why its incremental cost is modest ($40-$130/month for most small businesses). Standalone business-income policies exist for larger or specialized risks.
How much business interruption coverage do I need?
Estimate the net income plus continuing expenses (rent, payroll, loan payments) you'd need to survive a realistic worst-case restoration period. The most common mistake is under-estimating how long recovery takes — if a full rebuild would take 9 months, a 3-month limit leaves you exposed. Match the indemnity period to your realistic recovery time.
What's the waiting period on a BI claim?
Most policies have a short waiting period (a "time deductible") of about 48-72 hours after the covered loss before payments begin. Coverage then continues through the restoration period up to the policy's cap (commonly 12 months).
Does BI cover lost income if my supplier shuts down?
Only if you have Contingent Business Interruption coverage. Standard BI responds to a covered physical loss at your premises. Contingent BI extends that to income you lose when a key supplier or customer suffers a covered loss that disrupts your operations — important for manufacturers and businesses with concentrated supply chains.
Does business interruption cover payroll?
Usually yes — payroll for retaining employees during the shutdown is a standard part of business-income coverage, though policies vary on whether ordinary payroll is included in full, for a limited number of days, or excluded by endorsement to lower premium. If keeping your staff through a closure matters, confirm ordinary payroll is included and for how long.
