How to Calculate Wood Price: 2026 Cost-Per-Board-Foot Chart
Wood price is calculated by multiplying the price per board foot by the total board feet needed — length × width × thickness (inches) ÷ 144 — then adding 10–15% for cutting waste. Skipping that waste factor is the single most common reason DIYers run short mid-project and pay for a second delivery. This guide covers real 2026 per-species pricing, rough-sawn vs. surfaced (S4S) cost differences, and how professionals estimate lumber for a job.

Understanding Board Feet: The Core Pricing Formula
A board foot is a unit of lumber volume — not length — equal to a piece of wood 12 inches long, 12 inches wide, and 1 inch thick (144 cubic inches). It’s the standard unit hardwood dealers price by, which is why a short, wide, thick board can cost more than a long, narrow, thin one.
The formula: (Length in inches × Width in inches × Thickness in inches) ÷ 144 = board feet. Multiply the result by the price per board foot to get the cost. For other project math beyond pricing, see our full woodworking calculators guide.
Worked example: A rough-sawn red oak board measuring 96″ long × 8″ wide × 1″ thick works out to (96 × 8 × 1) ÷ 144 = 5.3 board feet. At $4/bf for rough-sawn red oak, that single board costs about $21.20 before waste is added. If you need to convert a bulk order between board feet and cubic feet, see how many cubic feet are in a board foot.
2026 Lumber Price Chart by Species (Per Board Foot)
Hardwood pricing varies by grade (rough-sawn vs. surfaced/S4S), and the gap between the two is bigger than most buyers expect — covered in detail further down. These 2026 ranges are compiled from direct hardwood dealer price lists (The Wood Yard, Hearne Hardwoods) and current industry pricing guides. Note this chart covers standard dimensional boards — live-edge and slab pricing follows a different model, covered in how to calculate wood slab price.
| Species | Rough-Sawn ($/bf) | Surfaced/S4S ($/bf) | Best For |
|---|---|---|---|
| Black Walnut | $6–$12 | $10–$18 | Fine furniture, accent pieces |
| White Oak | $5–$10 | $8–$15 | Outdoor-rated furniture, flooring |
| Red Oak | $2–$5 | $4–$7 | Cabinetry, general furniture |
| Hard Maple | $3–$6 | $5–$9 | Cutting boards, butcher blocks |

Construction Lumber & Plywood Pricing (SPF, Pressure-Treated, Sheet Goods)
Framing lumber and sheet goods are priced very differently from hardwood — usually per piece or per sheet rather than a hand-calculated board-foot price, though the board-foot rate is still what’s behind the sticker:
- SPF construction lumber: roughly $0.50–$0.90 per board foot — a standard 2×4×8 stud runs about $3–$6.
- Pressure-treated lumber: roughly $0.90–$1.60 per board foot — a PT 2×4×8 runs about $6–$10.
- Douglas Fir: roughly $0.70–$1.20 per board foot — about $6–$15 for a 2×4×8.
- 3/4″ CDX plywood (4×8 sheet): roughly $30–$80 per sheet nationally, with most regions currently landing around $40–$55.
If you’re pricing an entire framing job rather than one board, a dedicated lumber calculator for framing will total studs, plates, and joists faster than pricing each piece by hand.
Rough-Sawn vs. Surfaced (S4S): Why the Same Species Costs Double
Rough-sawn lumber is lumber straight off the sawmill — it hasn’t been planed flat or squared on any face, and the price chart above shows it consistently running 30–45% cheaper per board foot than the same species surfaced. Surfaced lumber (S4S — surfaced four sides) has been milled flat, square, and to a consistent thickness at the mill, which is why it costs more even though it’s literally less wood by volume once the rough faces are planed away.
The gap isn’t just labor — it’s yield. Milling a 1″-thick rough board down to a flat 3/4″ surfaced board removes roughly a quarter of its volume as shavings, and mills price the surfaced product to recover that loss. Buying rough-sawn only saves money if you have a planer and the shop time to mill it yourself; otherwise the “cheaper” rough-sawn price disappears once you pay someone else to surface it.
Don’t Forget the Waste Factor When You Buy
Every board-foot calculation above gives you the wood needed for a perfect, zero-waste cut list. Real projects never hit that number — defects, miscuts, and layout constraints all eat into your total, so professionals add a waste percentage before ordering:
| Cut complexity | Typical waste factor |
|---|---|
| Simple straight cuts | 5% |
| Standard framing/project work | 10% |
| Trim, millwork, complex layouts | 15% |
| Diagonal or pattern cuts | 20% |
| Irregular or curved shapes | 25% |
📊 Rough-sawn lumber typically loses close to half its volume by the time it’s milled to finished thickness — about 25% from planing 1″ rough stock down to 3/4″ finished, plus another 5–15% from straight-lining edges and cutting around defects. Source: WoodWeb industry milling-loss estimates.
“I’ve been quoted a cheap-looking rough-sawn walnut price online, only to find the surfaced price at pickup was nearly double once milling was added. Always confirm whether a quote is rough or S4S before comparing prices between two suppliers — they’re rarely quoting the same product.”

Smart-Buying Tips: Suppliers, Bulk Orders & Timing
- Big-box vs. local lumberyard: big-box stores are usually cheaper and more convenient for construction-grade SPF, PT lumber, and plywood. Local hardwood lumberyards almost always beat big-box on hardwood species and let you hand-pick boards for grain and defects — something you can’t do buying pre-packaged stock.
- Best time to buy: lumber demand (and price) typically eases in late fall and winter as the spring building season winds down; buying ahead of spring project season can mean better pricing and availability.
- Compare quotes on equal terms: get every supplier quote in the same units (per board foot, same grade, same rough-vs-surfaced state) before comparing — see the section above on why rough-sawn and surfaced prices aren’t comparable.
- Ask about quantity breaks: most yards discount orders over 100 board feet, and many will negotiate further on repeat business.
This board-foot math applies to straight-grain lumber. Figured and specialty wood like burl prices on a completely different scale — see our burl wood value guide for real per-board-foot pricing by grain type.
Common Mistakes When Estimating Wood Cost
- Forgetting the waste factor entirely — ordering the exact board-foot total from your cut list, then running short mid-project.
- Comparing a rough-sawn quote to a surfaced quote — a $4/bf rough-sawn oak quote and a $6/bf surfaced oak quote are close to the same real cost once you pay to mill the rough stock yourself.
- Confusing linear feet with board feet — a linear foot only measures length; it ignores width and thickness entirely, so it only works as a pricing unit for lumber sold in one fixed dimension (like a 2×4).
- Assuming kiln-dried and air-dried cost the same — kiln-drying takes controlled weeks instead of months or years of air-drying and carries a price premium for that speed and the lower risk of warping.
Frequently Asked Questions
How do you calculate the price per foot of lumber?
Multiply the board footage (length × width × thickness in inches, ÷ 144) by the price per board foot. For lumber sold strictly by linear foot, like a standard 2×4, just multiply the total length by the price per linear foot instead.
How much lumber do I need for a project?
Total the board feet for every piece on your cut list, then add a waste factor of 10–15% for standard work (see the waste-factor table above). For framing-specific quantities like studs and plates, a board-feet-needed calculator walks through the same math per piece.
Is it cheaper to buy from a big-box store or a local lumberyard?
For construction-grade SPF, pressure-treated lumber, and plywood, big-box stores are usually cheaper. For hardwood species, local lumberyards typically beat big-box pricing and let you hand-select boards.
What’s the best time of year to buy lumber for the best price?
Late fall through winter, after the spring/summer building rush eases demand. Buying ahead of spring project season typically means better pricing and more in-stock selection.
What’s the difference between board feet and linear feet when pricing lumber?
Board feet measure volume (length × width × thickness), which is why hardwood of varying widths and thicknesses is priced by board foot. Linear feet measure only length and work as a pricing unit solely for lumber sold in one fixed width and thickness, like dimensional 2×4s.
Why does rough-sawn lumber cost less than surfaced lumber of the same species?
Surfacing removes roughly a quarter of a rough board’s volume as shavings to make it flat and square, and mills price the surfaced product to recover that milling loss and labor. Rough-sawn only saves money if you have a planer and the time to surface it yourself.
Conclusion
Calculating wood price comes down to one formula — board feet × price per board foot — applied correctly to the right grade of lumber. Use the 2026 species chart above to sanity-check any quote, always confirm whether you’re comparing rough-sawn or surfaced pricing, and build in 10–15% waste before you order so a good estimate doesn’t turn into a second trip to the lumberyard.
