Business income insurance replaces the net income your business would have earned and pays the operating expenses that continue, such as payroll, while operations are suspended by direct physical damage from a covered cause of loss. Think of it as disability insurance for the business: the commercial property policy repairs the building, and business income coverage keeps the business financially alive until it reopens. It pays during the period of restoration, which ends when the damaged property should reasonably be repaired.
This guide explains how the most widely used form works: the ISO Business Income (And Extra Expense) Coverage Form, CP 00 30.
Business Income Insurance
Business income insurance replaces net income a business would normally earn and pays normal operating expenses, including payroll, that continue while operations are suspended by direct physical damage from a covered cause of loss. Coverage runs through the period of restoration.
What is business income insurance and why does it matter?
Business income coverage puts a business back where it would have been if the loss had not happened. After a disaster damages a business's property, the repair bill is only half the financial loss. The other half is revenue that stops or slows while fixed costs such as rent, loan payments, key employees' pay and taxes keep coming. Business income insurance, often called business interruption insurance, fills that gap.
Many owners go without it. The National Association of Insurance Commissioners (NAIC) says only 30 to 40 percent of small business owners carry business interruption insurance.[1] That matters because FEMA reports that 40 percent of businesses never reopen after a disaster.[2] Time-related losses are hard to picture before they happen, which is why this is the piece most often missing from otherwise solid commercial insurance programs.
What does business interruption insurance cover?
Business interruption insurance covers the income you actually lose during the period of restoration plus the extra costs of keeping the business running. Under CP 00 30, business income means:
- Net income: the net profit or loss before income taxes that would have been earned, and
- Continuing normal operating expenses, including payroll.
Note the word "loss" in that definition. A business that was running at a loss can still recover, because the policy pays continuing expenses minus the net loss, leaving the insured where it would have been. For a manufacturer, net income includes the net sales value of production lost during the shutdown.
Coverage has three requirements:
- A suspension of operations, meaning a slowdown or stop of business activity (operations do not have to cease completely).
- Caused by direct physical loss or damage at the described premises from a "covered cause of loss", usually the same causes of loss as your commercial property coverage.
- Loss sustained during the period of restoration.
How does the period of restoration work?
The period of restoration is the time the policy pays for: it runs from the loss until the property should be repaired or the business moves to a new permanent location. For extra expense coverage, it begins immediately after the direct physical loss. For business income coverage, many CP 00 30 editions start it 72 hours after the loss, a waiting period that works like a deductible measured in time. It ends on the earlier of the date the property should be repaired, rebuilt or replaced with reasonable speed and similar quality, or the date the business resumes at a new permanent location.
"Should be" matters. Dragging your feet on repairs does not extend the coverage, and the period is not cut short by the policy's expiration date.
What is extra expense coverage?
Extra expense is the necessary cost you incur during the period of restoration to keep operating that you would not have had without the loss: renting temporary space, equipping a replacement location, moving costs and overtime. Under CP 00 30, extra expense is paid to avoid or reduce the suspension whether or not it reduces the business income loss, but the cost to repair or replace property is covered only to the extent it reduces the loss. Extra expense shares the single limit shown on the declarations, and coinsurance does not apply to it.
Some businesses simply cannot close: hospitals, law firms, insurance agencies, newspapers. Their loss is almost entirely extra expense rather than lost income. ISO offers a separate Extra Expense Coverage Form (CP 00 50) for them, and a business income form without extra expense (CP 00 32) for the opposite case.
What additional coverages are built in?
CP 00 30 includes four additional coverages worth knowing:
| Additional coverage | What it does | Key numbers |
|---|---|---|
| Civil Authority | Pays when a government order prohibits access to your premises because of damage to other property, provided your premises sit within the prohibited area and not more than one mile from the damaged property | Business income starts 72 hours after the order, up to 4 weeks, while extra expense starts immediately |
| Alterations and New Buildings | Covers income lost when damage to a building under construction delays your opening | Period of restoration starts on the date operations would have begun |
| Extended Business Income | Keeps continuous coverage after reopening for customers trying to locate your business again | Up to 60 days after operations resume, extendable by option |
| Interruption of Computer Operations | Limited give-back for suspensions caused by destruction or corruption of electronic data | $2,500 annual aggregate unless increased |
Reopening day is rarely a back-to-normal day. If income is still down after repairs are finished, the Extended Period of Indemnity optional coverage can extend Extended Business Income in 30-day steps up to 730 days.
How much coverage do I need, and what about coinsurance?
You need a limit at least equal to the coinsurance percentage on your declarations times your net income and operating expenses for the 12 months after the policy starts, or the insurer pays only a proportional share of the loss. That is CP 00 30's coinsurance condition. Choosing the percentage is really choosing how long a worst-case shutdown would last.
Sizing the limit takes four steps:
Work through the financials
Start with net sales, cost of goods sold, operating expenses and net profit. The Business Income Report/Work Sheet (CP 15 15), which your underwriter will ask for, walks through the calculation.
Estimate the worst-case restoration period
Estimate how long it would take to rebuild, restock and rehire, plus the time to get back to normal income after reopening. Add time for permit delays, code upgrades a building official may require, and contractor shortages after a regional disaster.
Separate continuing from non-continuing expenses
Rent, insurance, key payroll and loan payments usually continue, while some utilities and ordinary payroll may not. Only continuing expenses belong in the estimate.
Pick a coinsurance strategy, or opt out
Maximum Period of Indemnity pays for up to 120 days, Monthly Limit of Indemnity caps each 30-day period at 1/3, 1/4 or 1/6 of the limit, and Agreed Value suspends coinsurance for 12 months once the underwriter has a current CP 15 15 worksheet. Skip the renewal worksheet and coinsurance applies again.
One exclusion is hidden in the definitions rather than the exclusions list. The period of restoration specifically leaves out any extra time needed to comply with an ordinance or law that regulates construction, so the extra months spent bringing an older building up to current code are uninsured unless you add the Ordinance Or Law Increased Period Of Restoration endorsement (CP 15 31). It pairs with the direct damage side of ordinance or law coverage, which pays for the upgrade costs themselves.
Frequently asked questions
Is business income insurance the same as business interruption insurance?
Yes. "Business interruption" is the common name and "business income" is the formal name in the ISO forms. Both describe time element insurance, which measures the loss by how long you cannot do business.
Does my business have to shut down completely to collect?
No. The form defines "suspension" to include a slowdown as well as a full stop. A restaurant running at half capacity after a kitchen fire has a covered suspension.
Does business income coverage pay if a road closure or evacuation order shuts me down?
Only through the Civil Authority additional coverage, and only if the order results from direct physical damage to other property by a covered cause of loss. Your premises must be inside the prohibited area and no more than one mile from the damaged property. Business income is paid starting 72 hours after the order, for up to four weeks. An endorsement (CP 15 32) can change the time and distance limits.
Does the policy cover losses from a cyber attack or data corruption?
Essentially, no. Suspensions caused by destruction or corruption of electronic data are excluded, apart from the small Interruption of Computer Operations coverage of $2,500 a year unless increased. For meaningful protection, you need a cyber policy.

Testing your business income limit
Business income insurance replaces your net income and pays continuing expenses, including payroll, while a covered shutdown keeps you from earning, and it pays through the period of restoration. Check on your declarations whether business income starts immediately or after a 72-hour waiting period. How much the insurer pays then depends on the coinsurance percentage you chose and the length of your Extended Business Income period. Before your next renewal, use the CP 15 15 worksheet to test your limit against a worst-case rebuild.
