The quote handoff carries your inputs and assumptions. Only an explicit base cost is suggested as a quote cost; prices, rates and measurements remain planning notes.

Understand the result

How it works

Kerf board feet = kerf (in) × board width (in) × thickness (in) × total cuts ÷ 144. Usable = purchased board feet − defect allowance − kerf board feet.

  • All cuts use the entered cross section. Defect and kerf allowances are treated as separate losses; exclude overlap to avoid double counting. This estimates volume, not a cut arrangement.
