Business Interruption Insurance 2026: 75% of Small Businesses Are Underinsured — Here's What It Actually Covers

# Business Interruption Insurance 2026: 75% of Small Businesses Are Underinsured — Here's What It Actually Covers

> **Quick answer:** Business interruption insurance replaces lost revenue and covers fixed expenses when a covered disaster forces your business to close. It typically costs $500 to $3,000 per year bundled into a Business Owner's Policy (BOP). The critical problem in 2026: 75% of small businesses are underinsured, and standard policies have a major gap — tariff-driven supply chain shutdowns and supplier failures often don't trigger coverage because there was no physical property damage. Knowing this gap exists is step one. Acting on it is what separates businesses that reopen after a crisis from the 43% that never do.

Business interruption insurance sounds simple until you need it. Then the exclusions show up. In 2026, with tariffs disrupting supply chains and trade restrictions now affecting nearly $2.7 trillion in global merchandise, small business owners are discovering their policies don't cover what they assumed. Here's exactly what business interruption insurance covers, what it misses, how much it costs — and the psychology of why so many business owners skip it until it's too late.

Business interruption insurance — also called business income insurance — is designed to keep your business financially alive while it's physically shut down. If a covered event forces you to close, the policy replaces what you would have earned and covers costs that don't stop just because you do.
