Why is waste factor needed for flooring?

Cuts, layout direction, damaged planks, and pattern matching all create overage needs beyond raw room area.

What waste factor is typical?

Many projects use 7-12%, while diagonal or complex layouts may require more.

Can I use this for tile and vinyl?

Yes. As long as you enter accurate box coverage for your product, the math is the same.

Does this include underlayment and trim?

No. This estimate is for flooring material boxes only.

Why are boxes rounded up?

Retail packaging is sold in full boxes, so ordering must round up to avoid shortages.
