What is business interruption insurance?

Business interruption (BI) insurance covers you against the loss of income you may suffer if you are forced to close your doors. Coverage activates if you must close temporarily after a disaster event or unforeseen circumstances.

You will receive compensation to provide you with the revenue you would have received if you were running as usual. You will also have protection for normal day-to-day operating expenses.

It is also referred to as loss of business income insurance. It helps you recover lost revenue and cover expenses. You can add this to an existing policy or as an add-on. It may be part of a comprehensive plan.

Do I need business interruption insurance?

Most businesses should put serious thought into getting this type of insurance. You never know when an unexpected event or disaster could occur and cause you to shut down.

Without it, you will lose revenue because you are not operating daily. Repairing and restoring your property after a disaster could take weeks or months. Every day that you are closed results in more lost revenue. Plus, you still have to pay the bills, your employees, and account for other expenses.

All organizations, especially new companies, start-ups, and SMBs, can benefit from it. Smaller establishments are less equipped and need to be financially stable enough to withstand a disaster, causing a sudden closure.

Newer companies typically have more difficulty recovering after a disaster or loss event. They are more likely to close after a loss if they do not have business interruption insurance.

What is the most common type of business interruption?

Many things can interrupt business operations. But two main threats top the list - fire and water:

Fire: Even a small fire can shut down a business for days or weeks. A business only takes a few minutes to go up in flames and experience significant damage.
Water: This is one of a business owner's biggest enemies. It can cause damage in many ways, such as a burst pipe, flood, significant rainfall, or leak.

Examples of what causes business interruptions

Any company with a physical location could have an interruption. It helps to protect you against loss events. Here’s a list of things that are most likely to cause a business interruption:

Fire and explosion
Water damage
Power outages
IT and website problems
Cyber hacking
Natural disasters
Machine and equipment failure
Supplier issues

You can also get protection from other unexpected events that hurt your operating ability. Examples include :

A fire at your top supplier’s warehouse.
A top customer experiences a disaster, preventing them from buying from you.

What is covered by business interruption insurance?

Business interruption insurance calculation

One of the most common questions we receive from our clients about business interruption coverage is, how is business interruption insurance calculated? Losses from a business interruption are more challenging to calculate than physical loss. There are some intangibles to consider. Different methods to calculate loss are also based on your business type, industry, and other considerations. Business interruption calculations can get complex. Here’s a simple BI calculation to help you understand how it works:

Lost income + Payroll + Operating expenses + Additional expenses = business losses from interruption

Lost income: Based on the average revenue. Consider seasonal revenue changes and the impact the closure has on potential future revenue.
Payroll: The cost to pay your employees, including benefits.
Operating expenses: The cost of normal operating expenses
Additional expenses: Additional costs of setting up a temporary location, repairs, communications, marketing, and additional payroll.

You will be expected to show proof of loss. Compensation for loss will be based on your coverage and up to your policy limits.

Note: This is a basic example for illustrative purposes. Insurers may use different methods to measure business interruption loss and compensation.
