About this calculator

Quick total cost from a per-LF price quote. Most dimensional construction lumber (2×4, 2×6, etc.) is priced per linear foot or per stick. Hardwoods more often per board-foot. Always confirm pricing unit on the receipt.

Frequently asked

Why per LF instead of BF?+
For dimensional lumber (fixed cross-section), LF is a simpler quote. For mixed-size hardwoods, BF normalizes for volume.
2×4 prices?+
Spruce/Fir: ~$0.40-0.80/LF. Pressure-treated 2×4: ~$0.80-1.50/LF. Engineered LVL: $5-15/LF.
Bulk discount?+
Often 5-10% if buying a unit (typically 200+ pieces). Worth asking.
Tax included?+
Usually not in quoted price. Add 5-10% for sales tax in most US states.
Delivery cost?+
Free over $500-1000 typically; otherwise $50-150. Worth bundling orders.
