Commercial property insurance rebuilds the building. It does nothing about the payroll, rent, loan payments, and lost profit that stack up over the twelve months the rebuilding takes. Business interruption is what keeps the company alive in between — and its limit is the number most often set once and never looked at again.
Property insurance answers the question of how the building gets rebuilt. Business interruption answers the harder one: what pays the bills, keeps the crew, and holds the customers while that happens.
Business interruption pays the income you would have earned and the expenses that keep running while you cannot operate. It is the coverage that determines whether a serious property loss is an expensive year or the end of the business.
What it covers
✓ Net income the business would have earned
✓ Payroll, rent, loan payments, and other continuing costs
✓ Extra expense to keep operating elsewhere
✓ Lost income at a supplier or key customer
✓ The ramp back up after you reopen
This is the most misunderstood thing about the coverage, and it caught a lot of business owners by surprise in 2020. Business interruption is triggered by direct physical loss or damage to covered property from a covered peril — a fire, a burst pipe, wind, a vehicle into the building. No physical damage generally means no business interruption claim, no matter how badly income is affected.
What is inside the coverage, though, is broader than most owners realize. Several extensions respond to losses that start somewhere other than your own building.
A covered loss at a supplier’s or major customer’s location that stops your production or your revenue. Essential for any manufacturer with a single-source supplier.
Off-premises power, water, or communications failure. Frequently excluded by default, and even when endorsed, overhead transmission lines are often carved out. Worth reading closely in Minnesota.
Government action blocking access to your property because of damage nearby. Usually capped at a short period, commonly around four weeks.
Physical obstruction preventing access to your premises, even when your own property is undamaged.
Damage to a nearby anchor business that drives your traffic. Relevant to retail and food service in shared centers.
The stretch after you reopen but before revenue returns to normal. Cheap to extend and routinely left too short.
The profit the business would have earned during the shutdown, based on historical performance and reasonable forward projections. Not revenue — profit, calculated from a gross earnings worksheet.
The costs that do not stop when production does — payroll, rent or mortgage, loan payments, insurance, utilities, equipment leases, and taxes. Keeping key employees through a shutdown is usually the difference between reopening and restarting.
The cost of operating somewhere else or working around the damage: temporary space, rented equipment, expedited shipping, overtime. Can also be bought standalone where continuing to operate matters more than recouping lost profit.
Coverage for the ramp back up after you reopen. Default endorsements are often 30 or 60 days. For a manufacturer who lost a production slot in a customer’s supply chain, 180 to 365 days is far more realistic.
The policy’s period of restoration ends when the property should be repaired or replaced with reasonable speed — not when you are back to pre-loss revenue. For a business that depends on one piece of equipment with a long lead time, the construction schedule is irrelevant. What matters is how long the machine takes to arrive. If a critical press is a fourteen-month order, a twelve-month period leaves a gap the policy will not fill.
Business interruption limits come from a gross earnings worksheet. If that worksheet was last completed when revenue was materially lower, the limit is short — and because business interruption commonly carries a coinsurance requirement, the shortfall reduces payment on a partial loss, not just a total one.
Reopening is not recovering. Customers who moved to a competitor during a nine-month shutdown do not all come back in week one. The endorsement that bridges that gap costs very little and is routinely left at a number nobody chose.
Some policies allow an agreed value option that suspends coinsurance entirely in exchange for a completed, current worksheet. If your carrier offers it and you are willing to do the worksheet properly, it removes the penalty risk from the equation.
The real number comes from a gross earnings worksheet. This gives you a realistic starting range in about a minute.
Current revenue, cost of goods sold, and the expenses that would continue during a shutdown. Twelve months forward, not twelve months back. This is the step most programs skip.
We look at what would actually have to be replaced and how long it takes to get. For manufacturers that means equipment lead times. For contractors it means fleet and specialty equipment.
Single-source suppliers, major customers, and utility exposure, so contingent business interruption is sized to something real rather than bought as a token limit.
Business interruption works alongside the coverages that trigger it. These pages explain how they fit together:
Most business owners can tell us their property limit. Very few can tell us their business income limit or where it came from. We will work through the worksheet with you either way.
Fill out the form and an agent will be in touch within one business day.
Period of restoration, coinsurance, extended period of indemnity, and contingent exposure are where business interruption claims are won or lost — and none of them get decided during the claim. They get decided when the policy is written.
Business interruption is the coverage I find wrong most often, and it is almost never because someone was careless. The number gets set when the policy is first written, revenue grows, equipment changes, and nobody goes back to the worksheet. I would much rather spend an hour on the math now than explain the gap to you during a claim. If you send me your declarations pages, I will tell you what I see — and if the limit is well built, I will tell you that too.
