As a homeowner, it's customary for lenders to demand the procurement of homeowners insurance covering at least a certain amount of the home's value. This specialized insurance shields your property from various damages, encompassing both the inner and outer facets. These protections extend to covered events such as burglary, fire, or natural disasters. Aside from meeting the requirements of your lender, the sense of security that comes with homeowners insurance is invaluable, assuring you that you possess the means to mend or reconstruct your home in the event of an unforeseen mishap. Whether you still have a mortgage or even if your home is paid off and you no longer have to deal with a mortgage lender, homeowners insurance can help protect the equity you have in your home.


When selecting a homeowners insurance policy and the coverage, it's important to ensure your home is not underinsured. To do that, you want to follow the 80% rule, also recognized as the 80/20 rule, in homeowners insurance.

The 80% Rule

The 80% rule in homeowners insurance stipulates that homeowners need coverage amounting to at least 80% of their home's total replacement cost value to secure full coverage from their insurance provider. Most insurance companies abide by this rule, and it's crucial for homeowners to adhere to it. Doing so not only helps avoid penalties for underinsurance but also guarantees ample coverage in case of unforeseen events affecting your home.


Therefore, it becomes imperative to be well-informed about your total replacement cost when determining the appropriate coverage. This cost represents the amount required to rebuild your home using current building supplies and labor rates in the event of any damage.

Calculation of Replacement Cost

Determining replacement value usually involves multiplying the average local per-foot rebuilding cost by the square footage of your house.


Given the complexity of calculating this total, many insurance companies offer to estimate this value on your behalf. Nevertheless, understanding the key factors that contribute to calculating your total replacement cost is crucial. These factors include the square footage of your home, any renovations or improvements such as changes to flooring, appliances, fixtures, roof updates, or new windows, the cost of replacing materials, labor expenses in case of repairs, and the value of both interior and exterior components.


Regularly reviewing your home's total replacement cost value is essential. Adjusting your home insurance coverage is necessary to prevent being underinsured, especially if you've recently undertaken renovations or home improvements. Most insurance companies will make this adjustment automatically at the time of your annual renewal. This proactive approach ensures that your coverage aligns with the current value of your property.

An Example of How the 80% Rule Works

To better understand the 80/20 rule, let's delve into an example that demonstrates the 80% rule in home insurance.


Imagine you buy a home valued at $1,000,000 for its total replacement cost, and your home insurance covers $700,000. Now, consider a scenario where a fire causes $600,000 worth of damage to your home. While it might seem logical to assume your insurance would cover the entire cost, given that the damages are less than the coverage amount, this assumption is incorrect.


To adhere to the 80% rule, considering your home's replacement cost value of $1,000,000, you should have secured $800,000 in coverage (80% of $1,000,000). Falling short of meeting this rule implies that you won't be fully covered for all damages. Consequently, you'll need to dip into your own funds to cover a portion of the repair expenses. This underscores the significance of aligning your coverage with the appropriate replacement cost value, ensuring comprehensive protection for unforeseen events.
