What it means
Standard property insurance pays to repair your physical building and replace damaged equipment, but it does nothing to help you pay ongoing bills while the doors are closed. This is where business interruption insurance steps in.
It is designed to protect your cash flow during a crisis, ensuring that your business can survive a period of enforced closure without going under. When disaster strikes, this type of insurance typically covers the net profit your business would have generated during that period based on historical records.
It also covers essential ongoing expenses that do not stop just because you are closed. These usually include commercial rent, employee wages, loan interest, and taxes.
Crucially, policies often cover temporary relocation costs if you need to rent a temporary office or storefront to keep serving customers while your primary location is repaired. To calculate your payout, insurers look closely at your past financial performance and future projections.
They want to determine what your revenue and costs would have been had the disruption never happened. It is important to note that these policies almost always require physical damage to insured property as a trigger, meaning standard market downturns or supply chain issues without property damage are generally excluded unless specific endorsements were purchased.
In practice, this coverage acts as a financial safety net for managers and owners. Without it, a few months of zero revenue combined with continuing fixed costs can drain cash reserves completely, leading to permanent closure.
By transferring this specific operational risk to an insurer, businesses can focus their energy on recovery rather than worrying about imminent bankruptcy. Think of business interruption insurance as a financial parachute.
Standard property insurance fixes the airplane if it is damaged, but the parachute ensures you keep floating safely rather than crashing when your income stream suddenly stops.
In practice
Real-world examples
Example 1
A boutique clothing shop suffers a severe water pipe burst, forcing a two-month closure for repairs. The insurance covers their monthly rent of $3,000 and replaces $8,000 in lost monthly profits.
Example 2
An independent accountancy firm experiences a devastating electrical fire. Their policy covers $15,000 a month to lease temporary office space and keep paying their core team of five staff members.
Example 3
A regional manufacturing business has a key assembly machine destroyed by a lightning strike. The policy reimburses $45,000 for delayed customer orders and ongoing fixed payroll during the six-week repair.

Formula
Calculation
Indemnity Payout = Lost Net Profit + Continuing Fixed Costs
This is the same as: Revenue lost during the closure - Costs saved because the business is closed
Worked example. A bakery normally earns $40,000 of revenue a month with operating costs of $30,000, a net profit of $10,000. It is shut for three months after a fire and its revenue falls to zero. Rent of $5,000 and furlough pay for key bakers of $4,000 continue each month.
- Lost net profit = $10,000 x 3 = $30,000
- Continuing fixed costs = ($5,000 + $4,000) x 3 = $27,000
- Indemnity payout = $30,000 + $27,000 = $57,000
Cross-check: revenue lost is $40,000 x 3 = $120,000. Operating costs stop at $30,000 - $9,000 = $21,000 a month, which includes ingredients of $11,000, so costs saved over three months are $21,000 x 3 = $63,000. Payout = $120,000 - $63,000 = $57,000, the same answer. A policy usually pays only for the agreed indemnity period, and often only after a short waiting period, so a closure that lasts longer than the period is not covered for the extra time.Case study
Seen in the real world
This is a fictional, illustrative scenario. Brighton Bakery, a popular local cafe and bakery, suffered a severe kitchen fire that forced a complete shutdown for three months. Fortunately, the owner, Sarah, had maintained a comprehensive business interruption policy. Before the fire, Brighton Bakery averaged monthly revenues of $40,000 with operating costs of $30,000, leaving a net profit of $10,000 per month.
During the three months of closure, revenue dropped to zero. However, Sarah still had to pay rent of $5,000 per month and retained her two senior bakers on partial furlough pay costing $4,000 monthly, while saving on raw ingredients and other running costs of $21,000 a month, including $11,000 of ingredients. Upon filing the claim, the insurance assessor calculated the payout based on lost profit plus continuing fixed expenses. Over the three months, the total indemnity came to $57,000 (representing $30,000 in lost profit and $27,000 in fixed rent and staff costs).
This vital injection of funds allowed Brighton Bakery to pay its bills, retain key talent, and reopen successfully without taking on crippling debt. The claim took several weeks to settle, so Sarah used her overdraft to cover the first month's bills and asked the insurer for an interim payment. Her up-to-date monthly accounts made it easy to prove the lost profit. She has since reviewed the sum insured every year, because a policy based on last year's lower profit would have left her short.
Watch out
Common mistakes
- Assuming standard property insurance automatically covers lost profits and ongoing wages during a closure.
- Underinsuring the business by failing to update the sum insured as revenue grows year over year.
- Failing to keep accurate, up-to-date financial records, which makes proving the lost income claim extremely difficult.
Questions
People also ask
Does this insurance cover a drop in sales if customers simply stop coming?
No. Policies almost always require a direct physical loss or damage, such as a fire or flood, to trigger the coverage.
How is the payout amount decided?
Insurers review your past financial accounts, tax returns, and sales trends to calculate what your profit would have been had the event not occurred.
Are staff wages covered during the shutdown?
Yes, many policies cover ongoing payroll, especially for key employees you need to retain so you can reopen quickly.
