A flat 10% waste allowance is the estimating shortcut almost every flooring bid leans on — and it’s often wrong in both directions.
Waste factor is a function of layout, not material
A simple running-bond LVP install in a rectangular room wastes very little material. The same product laid diagonally, or run through a room with heavy jogs, closets and transitions, wastes several times that. A flat percentage applied across an entire scope averages out the easy rooms and the hard ones — usually undercounting material on the rooms that actually need it.
We take off waste room by room
Instead of one blended percentage, we calculate waste per room based on layout complexity, plank/tile format, and pattern (straight lay, diagonal, herringbone, pattern-matched). A hallway with three doorways and a closet return gets a different factor than an open great room — because it should.
The margin impact compounds
A few points of waste factor on one room is a rounding error. Multiplied across every room type on a multi-unit project, it becomes a material-cost shortfall that shows up as lost margin — not a line item anyone can point to after the fact. We set waste by pattern and room geometry instead of applying one percentage across the scope.
