In the upcoming sections, we explore the typical procedure for calculating commercial property insurance, focusing on the commonly considered factors.

Property Value

The value of your commercial property is one of the basic factors that goes into calculations for coverage needs and rates.

Typically, an authorized appraiser or existing property assessment documents establish this value.

Future Earnings Potential

Insurance providers often factor in a property’s future earnings potential.

For instance, an established manufacturer’s new plant might be assigned higher potential earnings than a building for a completely new business.

Building Construction

Insurance providers assess the materials used in your property’s construction. Material considerations impact insurance rates and related elements such as:

  1. Fire resistance of materials
  2. Quality of electrical wiring
  3. State of essential building systems (like plumbing, HVAC)

Overall age and condition of your commercial property are also evaluated. Yet, updating an older building strategically can help mitigate these concerns.


The usage of a structure affects commercial property rates during calculations.

For instance, a building with welding and similar processes typically has higher insurance costs compared to one housing doctors’ offices.

Protections & Precautions

While making commercial insurance calculations, certain protections and precautions may lead to lower rates for you. Features or considerations of this nature that could contribute to reduced rates include:

Proximity to fire hydrants or fire stations
Fire and burglar alarm systems
Sprinkler systems
Property surveillance cameras

Exposure to Risk

Risk exposure is factored into commercial property insurance calculations.

For instance, if your business is in a high-crime neighborhood or a flood-prone area, you might face elevated rates.

Other Businesses in the Area

Although not major, it’s a factor in calculating commercial property insurance.

For instance, if your office is near a fireworks factory, it’ll be taken into account.

Getting a Fair Calculation

Commercial insurance is intricate, influenced by factors for rates and coverage.

To ensure a fair calculation for commercial property insurance, gather:

  1. Updated property condition documentation
  2. Proof of completed relevant updates
  3. Comparable area commercial property rates

Businesses face diverse risks, requiring varied insurance.
