Short answer

Business Interruption Insurance Calculator

$607,500Recommended coverage limit

Estimated premium for this limit: ~$2,430/yr ($203/mo). Choose the 'extended period of indemnity' endorsement — revenue rarely snaps back the day you reopen; 30–90 extra days of ramp coverage costs little.

How it's calculated: $337,500 lost profit + $270,000 continuing expenses over 6 months. Adjust the inputs below to recalculate for your own numbers.

Disclaimer: Estimates only — not insurance, tax, or legal advice. Actual premiums depend on underwriting, state, carrier, claims history, and plan details. Confirm numbers with a licensed agent, broker, or Healthcare.gov before acting.

Formula used

Limit = (revenue × margin ÷ 12 + continuing/mo) × months

Business interruption replaces what you would have earned (gross profit) plus the bills that keep arriving while you're closed. The standard trap: coinsurance clauses penalize underinsured limits — insure to at least 80–100% of the real exposure.

Why most BI claims underpay

Coinsurance: if you carry $250K of coverage but the formula says you need $500K, the insurer pays only half your claim. Second trap: the 'period of restoration' ends at physical repair — but your customers took 6 months to find you again. Extended-period endorsements and accurate worksheets fix both.

  • BI is triggered by covered property damage — pandemic closures were largely excluded.
  • Contingent BI covers losses when a key SUPPLIER or customer burns down.
  • Service businesses can often work remotely — need less limit; manufacturers need the most.

FAQ

How much business interruption coverage do I need?

Months of realistic downtime × (monthly gross profit + monthly continuing expenses). For most businesses that's 6–12 months — a fire rebuild with permitting routinely takes 9.

Does business interruption cover pandemics?

Standard policies require direct physical damage to insured property, and most now carry explicit virus exclusions. COVID-era claims were overwhelmingly denied. Specialized parametric products exist but are niche.

Is business interruption insurance worth it?

At roughly 0.4% of the limit per year, a $500K limit costs ~$2,000/yr. Given that a quarter of businesses never reopen after a major uninsured loss, it's among the highest-leverage coverages a physical business can buy.
