Business Interruption Insurance

Business interruption insurance (also called business income insurance) reimburses a company for lost net income and continuing fixed expenses — such as rent, payroll, and loan payments — when a covered property loss forces a partial or full shutdown. Coverage kicks in after a waiting period (typically 48–72 hours) and pays until operations resume, up to the policy's restoration period limit.

Who this is for: Any business with a physical location, revenue-generating operations, or supply-chain dependencies that could be disrupted by fire, storm, vandalism, or another covered peril.

TL;DR — Key Takeaways

• Business interruption (BI) insurance replaces lost net income plus continuing expenses after a covered property loss — it does not cover the physical damage itself (that is commercial property insurance).
• BI is almost always sold as an endorsement to a commercial property policy or as part of a Business Owner's Policy (BOP), not as a standalone product.
• Coverage has a waiting period (typically 48–72 hours) and a maximum restoration period (commonly 12 months, extendable to 24 months).
• Standard BI policies exclude pandemics, floods, and earthquakes — separate coverage is required for those perils.
• Annual premiums typically run 0.25%–1.5% of insured revenue, depending on industry, location, and limit selected.

What Does Business Interruption Insurance Cover?

Business interruption insurance covers the revenue and expenses a business would have earned and incurred had the covered loss not occurred. Specifically, it reimburses:

• Net income (profit) that would have been earned during the shutdown period
• Continuing fixed expenses — rent/mortgage, utilities, lease payments, and payroll for key employees retained during the shutdown
• Temporary relocation costs if the business moves to a temporary location to resume operations
• Extra expenses incurred to minimize the shutdown (e.g., renting emergency equipment, expediting repairs)
• Payroll continuation for retained employees during restoration (may require a separate payroll endorsement on larger policies)

What Business Interruption Insurance Does NOT Cover

How Business Interruption Insurance Is Structured

BI coverage is not a standalone policy. It is attached to a commercial property form — either as a Business Income (and Extra Expense) coverage form (ISO CP 00 30) or bundled into a Business Owner's Policy (BOP) for eligible small businesses. Key structural elements include:

Waiting Period (Deductible)

Most BI policies impose a 72-hour waiting period before coverage begins. Some carriers use a dollar deductible instead (common in manufacturing). The waiting period is not reimbursed.

Restoration Period

The maximum length of time the insurer will pay — typically 12 months, extendable to 24 months by endorsement. The period ends when the damaged property is (or could reasonably be) restored, not when revenue fully recovers.

Coinsurance Clause

Many BI forms include an 80% coinsurance requirement: you must insure at least 80% of your projected annual business income. If you underinsure, the carrier applies a coinsurance penalty that reduces the claim payout proportionally. Use an agreed value endorsement to suspend coinsurance if you are confident in your limit.

Extended Period of Indemnity

A coverage option (set in the ISO CP 00 30 Declarations) that extends coverage beyond the restoration period while revenue ramps back up — commonly available in 30-, 60-, 90-, or 180-day increments.

Business Interruption Insurance Cost by Business Type

Premium depends on annual revenue, industry risk class, property construction, location (CAT exposure), selected limit, and restoration period. The figures below are illustrative industry ranges for a 12-month restoration period with no extended period endorsement.

Ranges reflect standard market pricing as of mid-2026. Your actual premium will vary. Request a quote for your specific operation.

How to Calculate the Right Business Interruption Limit

Underinsuring BI is the most common and costly mistake. Follow this process to set an accurate limit:

1. Pull your last 12 months of net income from your P&L statement (or your accountant's file).
2. Add back continuing fixed expenses — rent, utilities, loan payments, insurance premiums, and key-employee payroll you would retain during a shutdown.
3. Project forward 12–24 months using your expected revenue growth rate; insurers look at projected, not historical, income.
4. Apply the coinsurance test: your limit must equal at least 80% of that projected annual business income figure, or you risk a coinsurance penalty at claim time.
5. Add Extra Expense coverage — most ISO forms include it, but verify the sublimit is sufficient for your temporary-relocation or expediting costs.
6. Consider a 24-month restoration period if your industry typically involves lengthy rebuilds (e.g., food processing, healthcare, specialized manufacturing).
7. Review annually — revenue growth, new equipment, or lease changes can make last year's limit inadequate.

Real-World Example: Restaurant Fire in Texas

Scenario (illustrative — not a guarantee of coverage or outcome):

A Houston, Texas barbecue restaurant with $1.2 million in annual gross revenue experiences a commercial kitchen fire. The fire destroys the kitchen and hood system; the property insurer pays to rebuild under the commercial property policy.

• Restoration period: 4 months (120 days) for permits, demolition, and rebuild
• 72-hour waiting period: First 3 days not covered
• Monthly net income + fixed expenses: ~$35,000/month ($420,000 annualized)
• BI payout: ~$140,000 (approximately 4 months × $35,000, minus the 3-day waiting period)
• Extra expense coverage: $18,000 for pop-up catering trailer rental during limited outdoor operations

Without BI coverage, the owner would have had to fund payroll, rent, and loan payments out of reserves — roughly $140,000 over four months — while generating zero revenue. With a well-structured BI policy, those costs were largely reimbursed.

Texas-specific note: Texas does not mandate BI insurance, but commercial lenders and some commercial leases require proof of business income coverage. Confirm requirements with your lender and landlord.

Frequently Asked Questions

What is business interruption insurance in simple terms?

Business interruption insurance pays your business's ongoing bills and replaces lost profit after a covered property disaster forces you to slow down or shut down. Think of it as a paycheck for your business while repairs are underway.

Is business interruption insurance included in a BOP?

Yes. A Business Owner's Policy (BOP) packages general liability, commercial property, and business income (BI) coverage into one policy for eligible small-to-mid-size businesses. BI limits in a BOP are often lower than a standalone endorsement, so review the limit carefully against your actual revenue.

Does business interruption insurance cover COVID-19 or future pandemics?

Standard ISO commercial property forms — and virtually all admitted carrier policies as of 2026 — exclude losses triggered by communicable disease or government shutdown orders not connected to direct physical damage. A small number of specialty insurers offer pandemic BI endorsements; availability is limited and premiums are high. [Verify with your broker for current market offerings.]

How long does business interruption coverage last?

The policy's restoration period sets the maximum: most standard policies cover 12 months. Extended restoration periods of 18 or 24 months are available by endorsement and are strongly recommended for businesses in industries with long rebuild timelines (manufacturing, healthcare, food processing).

What triggers a business interruption claim?

Coverage is triggered by a direct physical loss or damage to insured property caused by a covered peril (fire, windstorm, vandalism, etc.). The damage must be to your own property, unless you have a Contingent Business Interruption (CBI) endorsement covering supplier or customer locations.

What is the difference between business interruption and extra expense coverage?

BI replaces lost income and covers continuing fixed expenses. Extra expense coverage pays the additional costs above normal operating expenses that you incur specifically to minimize or shorten the shutdown — renting a temporary space, shipping product overnight, or leasing equipment. Most ISO commercial property forms bundle both; confirm your policy includes both components.

How is the business interruption claim amount calculated?

The insurer calculates the difference between projected revenue (based on historical financials and seasonal trends) and actual revenue earned during the restoration period, then adds covered continuing expenses. Documented books and records — tax returns, profit and loss statements, general ledgers — are essential. Keeping off-site backups of financial records dramatically speeds up the claims process.

Can I get business interruption insurance for a home-based business?

Standard homeowners policies explicitly exclude business income losses. A home-based business needs either a home-based business endorsement on the homeowners policy or a separate commercial policy. Coverage limits under home endorsements are modest; if revenue is significant, a standalone BOP is the better solution.

Why Morrow for Business Interruption Insurance

1. Independent agency, multiple carriers. Morrow places BI coverage with a panel of admitted and E&S market carriers — we are not captive to one company's appetite. That means we can find the right restoration period length, coinsurance waiver, and CBI extension for your specific operation rather than forcing your business into a one-size form.

2. Accurate limit-setting from the start. Underinsuring BI is the industry's most common coverage gap. Our producers walk through your financials before binding — not just at claim time — to build a limit that satisfies coinsurance requirements and reflects your real projected income.

3. Contingent BI and supply-chain expertise. For manufacturers, distributors, and multi-location retailers, we routinely structure CBI endorsements covering key suppliers and major customers — often an overlooked gap that standard BOP policies don't address.

4. Claims advocacy when it matters most. A BI claim involves your accountant, the carrier's forensic accountant, and a complex income calculation. Morrow stays in your corner throughout the adjustment process — reviewing the insurer's calculation, flagging underpayments, and helping you document extra expense spend.

5. Fast certificates and evidence of coverage. Commercial lenders and landlords requiring evidence of BI coverage get same-day turnaround on certificates of insurance [Morrow to confirm current processing SLA].
