Formula Used

Building Raw Loss = Rebuilding Cost × Building Damage %

Contents Raw Loss = Contents Value × Contents Damage %

Debris Removal = (Building Raw Loss + Contents Raw Loss) × Debris Removal %

Required Coinsurance = Rebuilding Cost × Coinsurance %

Coinsurance Ratio = Building Coverage Limit ÷ Required Coinsurance

Building Payout = min(Building Basis Loss × Coinsurance Ratio, Building Coverage Limit)

Contents Payout = min(Contents Basis Loss, Contents Coverage Limit)

Gross Covered Claim = Building Payout + Contents Payout + Extra Expense Payout + Debris Removal

Net Payout = Gross Covered Claim − Deductible

Owner Cost = Basis Total Loss − Net Payout

For Actual Cash Value, basis loss is reduced by depreciation. For Replacement Cost, depreciation is ignored in the payout basis.

FAQs

1) What does this fire damage insurance calculator estimate?

It estimates raw loss, adjusted loss basis, gross covered claim, net payout after deductible, underinsurance exposure, and likely owner cost from a fire-related property claim.

2) Does this tool replace an insurer or adjuster opinion?

No. It is a planning calculator for budgeting and policy review. Final settlement depends on policy wording, endorsements, inspections, exclusions, and insurer claim handling.

3) Why is coinsurance included?

Many property policies require a minimum insurance level relative to rebuilding value. If your limit falls below that target, a claim payment can be reduced even when the loss is partial.

4) What is the difference between replacement cost and actual cash value?

Replacement cost usually ignores depreciation in the payout basis. Actual cash value reduces the basis by depreciation, which often lowers the reimbursable amount for building or contents damage.

5) Should contents be valued separately from the building?

Yes. Personal or business contents often have a separate limit and loss pattern. Keeping them separate makes coverage gaps and reimbursement estimates more realistic.

6) Does the deductible always apply once?

Many policies apply one deductible per covered occurrence, but policy wording can differ. Review your declarations page and endorsements before relying on a single deductible assumption.

7) How can I choose a better building coverage limit?

Start with current rebuilding cost, add inflation guard, and compare the result with any coinsurance target. Limits based only on market value may leave important rebuilding costs uninsured.

8) Can this calculator be used for homes and commercial properties?

Yes. It works for both as a planning model. Enter rebuilding values, contents amounts, extra expense estimates, and policy limits that match your property type.
