Business Interruption Insurance

Frequently Asked Questions

What does business interruption insurance cover?

Lost net income, continuing fixed expenses (rent, payroll, loan payments), and extra expenses to relocate or restart after a covered property loss (fire, storm, etc.). It does NOT cover pandemic-related shutdowns unless specifically endorsed.

How much business interruption coverage do I need?

Calculate 12-18 months of gross profit + continuing expenses. Use historical financials and account for the time needed to rebuild and resume operations. The standard restoration period is 12 months but extended periods of indemnity (18-24 months) are recommended.

Why was COVID-19 not covered by business interruption?

Most policies require "direct physical loss or damage" to property. Courts have overwhelmingly ruled (Hartford, Cincinnati Insurance cases) that virus contamination doesn't qualify. Many policies added explicit virus exclusions after SARS in 2003-2006.

How This Calculator Works

Business interruption (BI) insurance - sometimes called business income coverage - replaces the earnings your company loses while a covered peril (fire, storm, equipment breakdown, civil-authority order) shuts you down. This tool does two jobs at once. First it estimates the recommended coverage you should carry, working from the gross earnings the policy is meant to protect rather than from raw revenue. Second it estimates the annual premium a carrier would charge, by applying an industry base rate to your revenue and then adjusting for the indemnity period you select and the waiting period (time deductible) you choose. You enter annual revenue, net profit, operating expenses, an extra-expense figure, your industry, the indemnity period in months, and the waiting period in hours; the calculator returns coverage, premium, daily income at risk, and a risk-tier note.

Formula / Method

Coverage is built on gross earnings, not revenue, because a shutdown does not relieve you of every cost. The tool approximates continuing operating expenses (rent, leases, core payroll, debt service) at 70% of total operating expenses: continuing opex = opex × 0.70. Annual gross earnings = net profit + continuing opex, and monthly gross earnings = annual gross earnings ÷ 12. Recommended coverage = (monthly gross earnings × indemnity months) + extra expense. Premium starts as base = revenue × industry rate (1.8% professional services up to 4.5% restaurants), is scaled by an indemnity multiplier (3 mo ×0.45, 6 mo ×0.70, 12 mo ×1.00, 18 mo ×1.30, 24 mo ×1.55), then by a waiting-period factor (≤24 h ×1.20, ≤48 h ×1.08, ≤72 h ×1.00, longer ×0.92). Daily income at risk = annual gross earnings ÷ 365.

Worked Example

A retail business has $1,000,000 revenue, $150,000 net profit, $600,000 operating expenses, $50,000 extra-expense coverage, a 12-month indemnity period, and a 72-hour waiting period. Continuing opex = 600,000 × 0.70 = $420,000. Annual gross earnings = 150,000 + 420,000 = $570,000, so monthly gross earnings ≈ $47,500. Recommended coverage = (47,500 × 12) + 50,000 = $620,000. Premium: base = 1,000,000 × 0.025 = $25,000; 12-month multiplier is 1.00 and the 72-hour factor is 1.00, so the annual premium stays near $25,000 - about $2,083/month, or 2.5% of revenue. Daily income at risk = 570,000 ÷ 365 ≈ $1,562/day, the figure the policy effectively backstops.

Common Mistakes

Insuring revenue instead of gross earnings - you over-insure by including costs (raw materials, shipping) that stop during a closure.

Choosing a 3–6 month indemnity period when your real rebuild or supply lead time runs 12–18 months - coverage runs out before you reopen.

Buying the shortest 24-hour waiting period for the premium credit, then discovering most short outages self-resolve before any longer one triggers a claim.

Forgetting extra-expense coverage, which funds the temporary location or rented equipment that actually gets you operating again.

Assuming a standard policy covers supplier or utility failures - those need Contingent BI and Service Interruption endorsements.

Tips & FAQ

What is the indemnity period? The maximum length of time the insurer will pay lost earnings, starting after the waiting period - 12 months is the market standard and roughly matches a typical rebuild. Why does the waiting period save money? It is a time deductible; you absorb the first 24–168 hours, so a longer wait earns a premium credit but exposes you to short outages. What endorsements matter? Contingent BI (supplier/customer shutdown), Service Interruption (utility outages), Leader Property (anchor-tenant closure), and Ingress/Egress (blocked access) close the most common gaps. Reference points: FEMA notes that roughly 40% of small businesses never reopen after a disaster and that a restaurant rebuild often runs 9–14 months. These figures are planning estimates from 2025 commercial-market rate cards (Insurance Information Institute, NAIC, SMB carrier data) and not a quote, binding offer, or insurance advice - confirm coverage, sub-limits, and pricing with a licensed commercial agent.
