Estimate the total cost of a water damage insurance claim based on the affected area, water source category, damage severity, and structural components involved.
Affected Area (sq ft)
Water Source Category
Category 1 – Clean Water (burst pipe, appliance overflow) Category 2 – Grey Water (washing machine, dishwasher) Category 3 – Black Water (sewage, flooding)
Damage Severity
Class 1 – Minor (small area, minimal absorption) Class 2 – Significant (entire room, carpet/walls affected) Class 3 – Extensive (ceilings, walls, floors saturated) Class 4 – Specialty Drying (hardwood, concrete, plaster)
Number of Floors Affected
Structural Components Affected
Drywall / Ceilings Flooring Replacement Mold Remediation Electrical Inspection HVAC / Ductwork
Insurance Deductible ($)

#### Formula
Step 1 – Water Mitigation Cost: Mitigation = Area × Base Rate ($/sqft) × Severity Multiplier × Floor Multiplier • Base Rate: Cat 1 = $3.75 | Cat 2 = $5.50 | Cat 3 = $8.25 per sq ft • Severity Multiplier: Class 1 = 1.0 | Class 2 = 1.4 | Class 3 = 1.85 | Class 4 = 2.3 • Floor Multiplier = 1 + (Floors − 1) × 0.15
Step 2 – Structural Repairs: Drywall = Area × $2.50 | Flooring = Area × $4.00 | Mold = Area × $3.25 × category/severity adjustments Electrical = $850 (flat) | HVAC = $1,200 (flat)
Step 3 – Contents Estimate: Contents = Area × $1.80 × Category Factor (Cat 1 = 1.0, Cat 2 = 1.2, Cat 3 = 1.5)
Step 4 – Additional Living Expenses (Class 3 & 4 only): ALE = Area × $0.90 × Severity Multiplier
Step 5 – Net Claim: Net Payout = max(0, Gross Total − Deductible)
#### Assumptions & References
- Water damage categories (1–3) follow IICRC S500 Standard for Professional Water Damage Restoration.
- Damage classes (1–4) follow IICRC S500 classification for moisture absorption and drying complexity.
- Base mitigation rates sourced from Xactimate pricing data and national averages (HomeAdvisor, Angi, 2023–2024).
