Homeowners Insurance Calculator

About this calculator

Homeowners insurance premiums are typically priced per $1,000 of dwelling coverage (Coverage A), which should reflect the cost to rebuild the home from scratch — not its market value or purchase price, since land value doesn't need to be “rebuilt.” This calculator multiplies your estimated rebuild cost by the insurer's rate per $1,000 to project an annual premium, and shows how raising your deductible (the amount you pay out of pocket before coverage kicks in) typically lowers that premium.

Underinsuring the dwelling is one of the most common — and costly — mistakes homeowners make, since many policies apply a coinsurance penalty that reduces claim payouts if the insured amount falls below a required percentage (often 80%) of the true rebuild cost. Homebuyers shopping for a policy, insurance agents, and mortgage lenders (who typically require proof of adequate coverage) use this kind of estimate to set dwelling limits that actually match local construction costs.
