Operating Financials & Continuing Overhead
Determine business income loss and necessary continuing expenses during a catastrophe.
Protecting Enterprise Cash Flow with Business Interruption Insurance
Business interruption insurance (also known as business income coverage) replaces lost net operating profit and covers ongoing operational overhead—such as commercial lease payments, key executive payroll, debt service, and taxes—when a direct physical loss (fire, windstorm, pipe burst) halts standard business operations. Properly estimating the required Period of Restoration and coinsurance requirements ensures your company receives full indemnification without costly underinsurance penalties.

Separates non-negotiable overhead (rent, senior payroll, insurance, debt) from variable costs that pause during shutdown.
Period of Restoration Scaling
Simulates 1 to 12-month physical rebuilding and tenant re-occupancy timelines to estimate total claim value.
Extra Expense Rider Modeling
Includes temporary office relocation, expedited hardware replacement, and remote infrastructure contingency budgets.

Frequently Asked Questions
How is business interruption insurance calculated?
The standard insurance formula is: Net Income (Profit or Loss before taxes) + Continuing Normal Operating Expenses + Extra Expenses incurred to minimize shutdown duration.
What is the Period of Restoration?
The Period of Restoration begins immediately after the physical loss (or after an agreed 24-72 hour waiting period deductible) and concludes when the property is repaired and returned to normal operating condition.
What is the coinsurance clause in business income policies?
A coinsurance clause requires policyholders to maintain coverage equal to a specified percentage (commonly 80%, 90%, or 100%) of annual gross insurable earnings. Underinsuring results in proportional claim payout reductions.
What is the difference between Business Interruption and Extra Expense?
Business Interruption compensates for lost operating profits and ongoing baseline expenses, while Extra Expense covers additional emergency expenditures (such as renting temporary workspace or leasing emergency generators) incurred to keep operating.
