#### Formula

1. Adjusted Cost per Linear Foot: Base Cost/ft = Material Rate × Style Multiplier × Size Multiplier Adjusted/ft = (Base × 40% material) + (Base × 60% labor × Region Multiplier) Final/ft = Adjusted/ft + (Labor Portion × (Stories Multiplier − 1)) 2. Gutter Line Cost = Linear Feet × Final Cost per Foot 3. Downspout Cost = Number of Downspouts × Per-Downspout Rate × Region Multiplier 4. Guard Cost = Linear Feet × Guard Rate per Foot 5. Removal Cost = Linear Feet × $1.00/ft × Region Multiplier (if applicable) 6. Total Cost = Gutter Line + Downspouts + Guards + Removal 7. Range = Total × 0.85 (low) to Total × 1.15 (high)
