💵 Plywood & Lumber Prices — Sheet Cost by Thickness and Type

At US big-box retailers a standard 4×8 sheet runs roughly $10 to $90 depending on thickness and grade. The cheapest 1/4″ luan panels sit near $10–$22, structural 1/2″ CDX sheathing lands around $25–$40, and the 3/4″ sanded ACX or birch panels most cabinet work needs run $55–$90. Marine-grade 3/4″ panels start near $90 and climb past $150 at specialty dealers. Prices are retail estimates verified in November 2026 and move with region and season.

A 3/4-inch 4×8 sheet costs $35–$55 as CDX-style sheathing, $55–$90 sanded (ACX or A2 birch face), $45–$70 pressure treated, and $90–$150+ in marine grade. The spread is the face and the core: the same thickness of wood carries a C-face for a third of the price of a furniture-grade A face over a void-free hardwood core. For a typical 12-sheet cabinet project, the difference between sheathing stock and sanded stock is roughly $300–$500.

A 1/2-inch 4×8 CDX sheathing sheet is about $25–$40 at major US retailers in 2026. Sanded 1/2″ panels (BC/AC) run $35–$55, and 1/2″ pressure-treated sits near $40–$60. At 1/2″ the price per sheet is close to half of an equivalent-grade 3/4″ panel, which is why shed roofs and utility shelving often drop to 1/2″ whenever the span allows — the span rating, not the price, should make that call.

Three structural costs sit on every panel: log supply (mills price standing timber and freight into the veneer), resin and adhesive (petroleum-linked), and mill capacity — when housing starts surge, structural panel demand absorbs the mills that also feed the retail racks. Retail plywood prices roughly doubled between 2020 and 2022 during the pandemic building boom, then settled about 20–30% off the peak but stayed well above 2019 levels. Buying sanded grades during building-supply sales and structural panels in bulk units of 10–30 sheets recovers 5–15%.

A 2×4×8 SPF #2 stud costs about $4–$7 per piece at US big-box stores in 2026, and precut 92-5/8″ wall studs run slightly less at $3.50–$6. Prices swing hardest on this exact product — the 2×4 is the commodity index of framing lumber, and it can double during building booms. For a 20-stud wall frame, budget $80–$140 in studs plus $15–$30 in plates, which is why framing packages are usually quoted per-thousand-board-feet by contractors.

Marine-grade plywood runs $90–$150 for a 3/4-inch 4×8 sheet — roughly double sanded ACX and triple CDX. What the money buys is a void-free core and a verified boiling-water-proof glue line, not a waterproof coating. It is worth it where a hidden core void would fail something critical: boat hulls, exterior doors, transoms, permanently wet assemblies. For a shed roof or a painted planter, sealed exterior-grade ply does the same job for a third of the price.

A 3/4-inch 4×8 birch-faced plywood sheet with an A2 grade runs $55–$90; true Baltic birch is sold in 5×5 sheets and costs $60–$100 for 18 mm, which works out to a higher price per square foot but gives you 13 void-free plies and clean exposed edges. Baltic birch is worth the premium where edges show — drawer boxes, jigs, exposed shelving — and hard to justify where a face frame or edge banding hides everything.

Multiply the sheet count by the unit price, then add 8–12% for sales tax and delivery. The reliable sequence: first get the sheet count from the multi-room plywood calculator or the area-based plywood calculator, then refine it with the cut list calculator so offcut reuse is counted rather than guessed, and finally multiply by a real rack price from the tables above. A 100 sq ft subfloor at 23/32″ T&G needs about 5 sheets — roughly $190–$300 at 2026 prices — plus $20–$35 in construction screws.

Bulk wins when you will genuinely use the stock. Big-box stores sell structural sheathing in unit packs (typically 10–30 sheets) at a visible discount of about 5–12% per sheet, and lumber yards quote better per-sheet prices than retail racks on 25+ sheet orders with delivery. But 3/4″ sanded and specialty panels rarely get bulk pricing — those are priced by the sheet at retail everywhere. The worst outcome is bulk-buying sheathing that warps in a garage for two years: the discount evaporates.

Yes, and the pattern is consistent enough to plan around. Framing lumber typically softens in late fall and winter (November–February) when construction slows in northern states, and peaks in late spring as building season opens. Plywood moves less dramatically because panel production is steadier, but the same seasonal curve is visible. For a non-urgent project, buying sheet goods and framing lumber between December and February has historically saved 8–15% against the spring peak — a real saving on a 20-sheet order.
