More Variations
Dwelling coverage calculator for Coverage A checks
This tool compares the number on your declarations page with a replacement cost estimate. It helps you see whether a total-loss rebuild could exceed your current dwelling limit.
Why extended replacement cost matters
Some policies include an endorsement that adds extra coverage above the base dwelling limit. The calculator shows both the base gap and the gap after extension, which is the number homeowners often miss.
Use before renewal or after home improvements
Coverage can become stale after renovations, additions, material inflation, or local construction cost changes. Run the check before renewal and after major improvements.

Frequently Asked Questions
How much dwelling coverage do I need?▾
A common target is enough Coverage A to rebuild the home with similar materials after a covered total loss. Use a current replacement cost estimate, not the purchase price or tax value.
What is Coverage A?▾
Coverage A is the dwelling limit on a homeowners policy. It generally applies to the main structure, but policy language and exclusions vary.
What is extended replacement cost?▾
Extended replacement cost can increase the available dwelling limit by a percentage, such as 10%, 25%, or 50%, if rebuilding costs exceed the base Coverage A limit.
Does this calculator include personal property?▾
No. It focuses on dwelling coverage. Personal property, loss of use, other structures, and liability limits are separate parts of a homeowners policy.
What if the calculator shows a gap?▾
Ask your insurer for an updated replacement cost estimate and quote higher dwelling coverage or extended replacement cost if available.
