What is replacement cost in insurance?

Replacement cost is the amount needed to rebuild or repair your home using materials of like kind and quality at current prices, without deducting for depreciation. It differs from market value (which includes land and location) and actual cash value (which subtracts depreciation).

How is cost per square foot determined?

Construction cost per square foot varies by region, labor market, and material prices. The regional presets in this tool use broadly averaged figures. For a precise estimate, contact a local contractor or appraiser, or reference the Marshall & Swift / CoreLogic cost guides your insurer may use.

Should I insure for market value or replacement cost?

Insure for replacement cost, not market value. Market value includes land (which cannot burn down) and fluctuates with real estate demand. Replacement cost reflects only what it costs to rebuild the structure, which is the actual exposure your insurer covers.

What happens if I am underinsured?

If your coverage limit is below your true replacement cost, you bear the gap out of pocket after a total loss. Many policies also apply a coinsurance clause that reduces partial-loss payouts when coverage falls below 80% of replacement cost.

Does this include the cost of land?

No. Replacement cost for insurance purposes covers the structure only — not the land beneath it. Land is excluded from dwelling coverage because it is not destroyed in a fire or storm.

How often should I update my replacement cost estimate?

Review it annually, or after any major renovation. Construction costs have risen sharply in recent years; a figure that was accurate three years ago may now understate your real exposure by 20–40%.
