Estimate the cost to rebuild a home from its floor area, a build rate per square foot, and an optional complexity adjustment.
Rebuild cost is what it would take to reconstruct your home, which insurers use to set cover, not its market value. Multiply the floor area by a local build rate per square foot. A 2,000 square foot home at $150 a square foot is about $300,000. Complex builds cost more; this figure excludes the land.

What Is Rebuild Cost?
Rebuild cost, sometimes called reconstruction cost, is what it would take to rebuild your home from the ground up after a total loss. Home insurers use it to set the amount of cover, and it is deliberately different from market value, which includes the land and location.
Because it excludes the land, rebuild cost can be higher or lower than what the property would sell for. Insuring to the wrong figure risks being underinsured after a claim.
How to Estimate Rebuild Cost
Rebuild cost = Floor area x Build rate per sq ft (+ complexity)Multiply the finished floor area by a local build rate. A 2,000 square foot home at $150 a square foot is about $300,000. Adding a complexity adjustment for high-end finishes or a difficult site raises the estimate.
How to Read Your Result
The main figure is the estimated rebuild cost. The base box shows the cost before any complexity adjustment, and the per-square-foot box shows the all-in rate, which is easy to compare against local building figures.
More detail
Rebuild Cost vs Market Value
Market value reflects what a buyer would pay, including the land and the desirability of the location. Rebuild cost only covers reconstructing the structure. In expensive areas the market value is often far higher than the rebuild cost, while the reverse can happen where land is cheap.
If you are budgeting a purchase rather than insurance, the mortgage calculator and home equity calculator work from market value instead.
Making the Estimate More Accurate
Build rates vary widely by region, materials and finish, so use a local figure rather than a national average. For specific materials on a project, the paint coverage calculator and other tools in the construction hub help you cost the details.
Is rebuild cost the same as my home value?
No. Rebuild cost is what it takes to reconstruct the building and excludes the land. Market value includes the land and location, so the two figures are often quite different.
What build rate should I use?
Use a local cost per square foot for your area, quality of finish and type of construction. National averages are only a rough starting point because building costs vary widely by region.
Why does rebuild cost matter for insurance?
Home insurers set cover based on rebuild cost. Insuring for market value can leave you underinsured or overpaying, so matching the policy to the rebuild figure is important.
Does this include the land?
No. Land is not destroyed in most losses, so rebuild cost and insurance cover exclude it. This estimate is for the structure only.
Is my data saved?
No. The calculation runs in your browser and nothing you enter is stored.
