What This Calculator Does
The Lumber Cost Calculator computes the total cost of dimensional lumber based on board feet or linear feet and the current price per unit. Enter the quantity and unit price to get the total lumber cost for your framing, decking, or woodworking project.
Lumber prices in the US are highly volatile, influenced by housing starts, seasonal demand, and mill production. In 2026, dimensional lumber (2x4, 2x6, 2x8) ranges from $1.20-$2.00 per board foot depending on species and region.
For a typical 2,000 sq ft house, framing lumber represents approximately $12,000-$20,000 of the total material cost. Using this calculator helps you compare quotes from multiple suppliers.
