How much dwelling coverage do you actually need? This free home insurance coverage estimator uses your home’s square footage to suggest a starting dwelling, personal property, and liability coverage range.
Rebuild cost per sq ft varies significantly by region – check local construction cost data or ask your insurer for an accurate figure.
This is a general starting estimate based on rebuild cost, not market value. Always confirm exact coverage needs with a licensed insurance agent.
How the Home Insurance Coverage Estimator Works
Home insurance coverage estimation starts with one question: what would it cost to rebuild your house from the ground up, not what it would sell for on the market. This tool multiplies your home’s square footage by a local rebuild cost per square foot to suggest a starting dwelling coverage figure, then derives personal property and liability guidance from that number.
Formula: Dwelling Coverage = Square Footage × Rebuild Cost per Sq Ft. Personal Property Coverage = Dwelling Coverage × 0.6. Suggested Liability Coverage = $300,000 (a common baseline minimum, shown as “300,000+” since needs can run higher).
- Home square footage — the total finished square footage of the structure you’re insuring, entered in the “Home square footage” field.
- Rebuild cost per sq ft — your local cost to rebuild, entered in dollars in the “Local rebuild cost per sq ft” field; the calculator falls back to $150/sq ft if this is left blank or invalid.
- Dwelling coverage — the suggested amount to insure the structure itself, shown as the main result.
- Personal property (60%) — a starting estimate for belongings coverage, calculated as 60% of dwelling coverage.
- Suggested liability — a flat $300,000+ baseline shown regardless of home size, since liability needs depend more on assets and risk exposure than square footage.

Home Insurance Coverage Estimator FAQ
How much dwelling coverage do I actually need for my home?
Start with your home’s square footage multiplied by the local cost to rebuild per square foot, not its market sale price. Land value isn’t included since it doesn’t burn down or need replacing. This estimator gives a starting figure — a licensed agent can refine it using your home’s actual construction details.Why does rebuild cost per square foot matter more than my home’s market value?
Market value includes land, location demand, and neighborhood pricing, none of which apply to an insurance claim after a total loss. Insurers pay to rebuild the structure, so construction cost per square foot in your area is the number that actually drives your dwelling coverage need.Is personal property coverage always 60% of dwelling coverage?
60% is a common industry starting guideline used by many standard homeowners policies, not a fixed rule. If you own significant high-value items or work from home with expensive equipment, you may need to increase this percentage or add a separate endorsement.What does the $300,000 minimum liability coverage cover?
Liability coverage pays for injuries or property damage you’re legally responsible for that happen on your property or are caused by your household. The suggested $300,000+ figure is a common baseline; households with significant assets to protect often carry more.Where do I find my local rebuild cost per square foot?
Local contractors, your insurance agent, or regional construction cost data services can provide current rebuild estimates. Costs vary significantly by region due to labor rates, material costs, and local building codes, so a national average won’t be accurate for your area.Does this estimator account for high-value items like jewelry or art?
No. The personal property estimate is a general percentage of dwelling coverage and doesn’t account for individually valuable items. Jewelry, art, collectibles, and similar items typically need a separate scheduled endorsement with its own appraisal and coverage limit.Related Calculators
