Homeowners Coverage Amount Calculator
Estimate the dwelling, personal property and liability coverage to insure your home to its rebuild cost — not its market price.
How it works
Dwelling = size × rebuild cost per sq ft · Personal property = dwelling × contents% · Loss of use ≈ dwelling × 20%
Homeowners insurance should cover the cost to rebuild your home, which is often very different from its market or purchase price — market value includes the land, which never needs rebuilding. Dwelling coverage (Coverage A) is the anchor; personal property is typically set at 50–70% of the dwelling, and loss-of-use around 20%. Insurers usually require you to insure to at least 80% of rebuild cost to avoid a coinsurance penalty on partial claims.
Worked example
A 2,000 sq ft home at $175/sq ft to rebuild needs $350,000 of dwelling coverage. Personal property at 60% adds $210,000, loss of use at 20% adds $70,000, for roughly $630,000 of coverage before liability.
Frequently asked questions
Should I insure my home for its market value?
No — insure it for the rebuild (replacement) cost. Market value includes the land, which does not burn down, so insuring to market value usually means paying for far more coverage than you could ever claim.
How much personal property coverage do I need?
Standard policies set personal property at 50–70% of the dwelling amount automatically. If you own high-value items — jewelry, art, collectibles — you may need scheduled endorsements above that limit.
What is the 80% coinsurance rule?
Most policies require you to insure to at least 80% of full rebuild cost. If you are underinsured below that, the insurer can reduce even partial claim payouts proportionally, so keep your dwelling limit current with construction costs.
