Estimate the recommended dwelling coverage for your home insurance policy.
Understanding Dwelling Coverage
Dwelling coverage, also known as Coverage A, is a crucial part of your homeowners insurance policy. It protects the physical structure of your home against covered perils such as fire, windstorms, hail, and vandalism. This coverage typically pays to repair or rebuild your home if it's damaged or destroyed by a covered event.
How Dwelling Coverage is Calculated
The primary method to determine adequate dwelling coverage is by estimating the cost to rebuild your home from the ground up. This is not based on the market value or assessed value of your home, but rather on the actual cost of materials and labor in your specific location.
Our calculator uses the following formula to provide an estimated dwelling coverage amount:
Main Dwelling Cost: Total Square Footage * Cost Per Square Foot to Rebuild
Finished Basement Cost: Basement Square Footage * Cost Per Square Foot to Rebuild * Basement Cost Multiplier
Total Estimated Rebuild Cost: Main Dwelling Cost + Finished Basement Cost
Recommended Dwelling Coverage: Total Estimated Rebuild Cost + Coverage for Other Structures
Key Factors to Consider:
Cost Per Square Foot: This can vary significantly by region, the quality of materials used in construction, and current labor costs. Always aim for an up-to-date and localized estimate. You can often find this information from local contractors, builders, or real estate professionals.
Basement Finishing: If you have a finished basement, it adds to the total cost of rebuilding. The 'Basement Cost Multiplier' accounts for potential differences in rebuilding costs compared to the main house. A multiplier of 1.0 would mean it costs the same per square foot as the main house, while a lower multiplier (like 0.8) reflects a potentially lower cost per square foot for basement finishes.
Other Structures: This includes detached structures on your property like garages, sheds, gazebos, fences, or swimming pools. Ensure these are adequately covered.
Inflation Guard: Many policies include an "inflation guard" endorsement that automatically increases your dwelling coverage limit annually to keep pace with rising construction costs.
Guaranteed/Extended Replacement Cost: For added protection, consider policies offering guaranteed or extended replacement cost, which provides extra coverage beyond your dwelling limit if rebuilding costs exceed it.
Why This Calculator is Useful
Using a dwelling coverage calculator helps you:
Avoid Underinsurance: Ensures you have enough coverage to fully rebuild your home after a major loss, preventing significant out-of-pocket expenses.
Prevent Overinsurance: Avoid paying premiums for more coverage than you actually need.
Informed Decisions: Provides a data-driven starting point for discussions with your insurance agent.
