#### Formulas Used

Adjusted Gutter Footage = Linear Footage × (1 + Waste% / 100)

Gutter Channel Cost = Adjusted Footage × Unit Cost ($/ft by material & size)

Downspout Cost = (Number of Downspouts × Height × Waste Factor) × Downspout $/ft

Number of Hangers = ⌈ Linear Footage ÷ Hanger Spacing ⌉

Total Material Cost = Gutter Channel + Downspouts + Corners + End Caps + Hangers + Outlets

Cost per Linear Foot = Total Material Cost ÷ Original Linear Footage
