All calculators use nominal lumber dimensions (the size you ask for, e.g. 2×4) with the industry-standard board feet formula: (thickness × width × length) ÷ 12. Results include a 10% waste factor by default and a cost estimate at ~$0.85/BF that you can adjust in each calculator. Always confirm pricing with your local lumber yard before ordering.
