Flooring Waste
Add waste allowance to a room area for flooring orders.
About Flooring Waste
The waste allowance is applied to the room area to cover cutting, off-cuts and the odd damaged plank. Flooring must be bought all at once, so ordering the extra up front avoids a dye-lot mismatch on a reorder.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
