Use this homeowners insurance calculator as a planning checkpoint. It is designed to flag underinsurance risk, deductible cash pressure, weather add-ons, and escrow impact. It does not replace an insurer's replacement-cost estimator or a bindable quote.

Methodology
The calculator chooses dwelling coverage from the entered rebuild cost when provided, otherwise square footage multiplied by rebuild cost per square foot. It rounds dwelling coverage up to the nearest $10,000 and compares it with an 80% replacement-cost threshold based on the structure estimate.
Other structures, personal property, and loss-of-use are estimated as percentages of dwelling coverage. Liability coverage is displayed from the selected limit.
The base premium midpoint uses a simplified dwelling-rate factor, then adjusts for deductible, liability limit, roof age, home age, and location/weather risk. Flood, earthquake, and wind/hurricane selections are added as annual planning amounts and shown separately.
The premium range is a planning range only. Actual quotes depend on address-level underwriting, discounts, claims history, credit-based insurance score where allowed, roof shape/material, mitigation features, inspection results, and carrier appetite.
Important caveats
- Insurer replacement-cost estimators can differ materially from this calculator. Use actual quotes and the insurer's coverage forms before binding coverage.
- Replacement cost is not the same as market value. Market value includes land, location, demand, and financing conditions; dwelling coverage is about rebuilding the structure after a covered loss.
- Standard homeowners policies commonly exclude flood and earthquake damage. Wind, hurricane, named-storm, hail, and wildfire terms vary widely by state and carrier.
- Flood, earthquake, wind, and hurricane deductibles may be separate and may use percentages instead of flat dollar amounts.
- Roof age, roof condition, prior claims, vacant homes, older wiring or plumbing, wood stoves, pools, short-term rental use, and local wildfire or coastal exposure can change eligibility and price.
- Lenders usually require enough hazard insurance to protect the loan and may impose escrow, coverage, and deductible requirements.
- This calculator is educational planning math. It is not insurance, legal, tax, construction, or financial advice.

Frequently asked questions
How much homeowners insurance do I need?
Start with enough dwelling coverage to rebuild the home at local replacement cost, then check other structures, personal property, loss-of-use, liability, deductible, lender, and add-on needs.
Is dwelling coverage based on purchase price?
Usually no. Purchase price includes land and market demand. Dwelling coverage should be tied to the cost to rebuild the structure after a covered loss.
Should I include flood or earthquake coverage?
Price them separately when the risk is plausible because standard homeowners policies commonly exclude those losses. Lenders may require flood coverage in certain flood zones.
Does a higher deductible always save money?
Not always. It can reduce premium, but the savings are only useful if you can comfortably pay the deductible after a loss and if separate peril deductibles do not create a larger exposure.
