We start from your wall area, subtract optional opening deductions (capped so you cannot deduct more than the total wall area), then scale by wastage to get adjusted covered area. That area is multiplied by your effective price per square foot—either entered directly or converted from price per square by dividing by 100. The dollar estimate is materials-only; labor and accessories are separate.
net sq ft = wall sq ft − min(deductions, wall sq ft)adjusted sq ft = net sq ft × (1 + wastage% ÷ 100)squares = adjusted sq ft ÷ 100cost = adjusted sq ft × ($/sq ft)More exterior projects? Vinyl fence cost and concrete stepping stone.
