Introduction
Sheet count is only half the budget — the other half is what each sheet costs. A 3/4″ sanded sheet can cost twice what a 1/2″ CDX sheet does, and specialty panels like marine-grade plywood sit in a different price universe entirely. Knowing the typical ranges before you shop keeps a lumberyard trip from turning into sticker shock.
The Plywood Sheet Calculator gives you the sheet count; this guide converts that count into money. Multiply your sheets by the per-sheet price for your chosen thickness and grade, add tax and delivery, and you have a realistic material budget. All prices below are typical US retail ranges — they move with region, season, tariffs, and lumber markets, so treat them as planning figures and confirm with local suppliers.
Typical Sheet Prices by Thickness and Grade
Plywood pricing follows two axes: thickness (more material, higher price) and grade (better faces and cores, higher price). These are typical per-sheet retail ranges at big-box stores and lumberyards:
| Thickness | CDX (construction) | BC / sanded | Marine-grade |
|---|---|---|---|
| 1/4″ (6.35 mm) | $18–$30 | $25–$40 | $60–$100 |
| 1/2″ (12.7 mm) | $28–$45 | $38–$55 | $80–$130 |
| 5/8″ (15.9 mm) | $35–$55 | $45–$65 | $95–$150 |
| 3/4″ (19.05 mm) | $42–$65 | $55–$80 | $110–$175 |
Underlayment panels (thin, smooth, for under flooring) typically run $20–$40 per sheet depending on thickness; hardwood plywood for cabinetry runs $50–$100+ per sheet by species. The material guide explains what each grade is actually for, so you don’t pay for quality the job doesn’t need.
CDX vs BC vs Sanded: What You’re Paying For
CDX is the workhorse construction panel: a C-grade face, D-grade back, exterior glue. It’s the cheapest structural option and the right call for sheathing that will be covered — wall sheathing behind siding, roof decks under shingles, subfloors under flooring. Paying for a prettier face here buys nothing.
BC gives you a B-grade face (smooth, few patches) over a C back — the step up for surfaces that stay visible or get painted, like soffits, garage interiors, or painted accent walls. Expect to pay roughly 25–40% more than CDX in the same thickness.
Sanded / AC panels have an A or B face sanded smooth at the mill. These are finish-grade sheets for visible work — shelving, painted built-ins, underlayment that takes finish flooring directly. The premium over CDX is 40–80% depending on thickness and species.
The expensive mistake is buying in the wrong direction: sanded plywood for hidden sheathing wastes money, while CDX for a visible painted surface costs you hours of filling and sanding. Match the grade to the exposure, not the budget line.
1/2″ vs 3/4″: The Two Most Common Choices
Most residential sheet counts land on one of these two thicknesses, and the price gap is real:
- 1/2″ (12.7 mm) CDX — typically $28–$45 per sheet. The standard for wall sheathing and many roof decks. Our canonical 12 × 16 ft wall (7 sheets) runs about $196–$315 in material.
- 3/4″ (19.05 mm) CDX or T&G — typically $42–$65 per sheet. The standard for subfloors, where stiffness matters. A 12 × 16 ft floor (also 7 sheets) runs about $294–$455.
Switching from 3/4″ to 1/2″ to save money on a subfloor is a false economy — the floor will feel bouncy and may not meet span requirements. Conversely, sheathing a shed wall in 3/4″ when 1/2″ is specified is money spent on stiffness the wall doesn’t need. Thickness is a structural decision first and a cost decision second.
What Drives the Price Beyond Thickness and Grade
- Region and freight. Prices run higher in the Northeast and on the West Coast, lower near southern mills. Remote delivery adds freight per load.
- Market cycles. Plywood prices swing with lumber futures, tariffs, and storm-driven demand. A range quoted last year may be stale — re-check before budgeting.
- Quantity. Full-unit (lift) pricing at lumberyards often beats per-sheet big-box pricing by 10–15% once you’re buying 30+ sheets.
- T&G and specialty edges. Tongue-and-groove subfloor panels cost a few dollars more per sheet than square-edge — worth it for the stiffness between joists.
- Delivery fees. Typically $50–$100+ per load; factor it in, and consolidate orders so you pay it once.
Worked Example: Budgeting the Canonical Wall
Take the standard example: a 12 ft × 16 ft surface = 192 sq ft → 6.0 sheets + 10% waste → 7 sheets.
Sheets: 192 ÷ 32 = 6.0 → × 1.10 = 6.6 → 7 sheets of 1/2″ CDX.
Step 2 — Grade and thickness. A wall like this typically takes 1/2″ (12.7 mm) CDX at $28–$45 per sheet.
Step 3 — Material. 7 × $28 = $196; 7 × $45 = $315. Budget range: $196–$315.
Step 4 — Add-ons. Sales tax (~$15–$25 on this range) and delivery if you can’t haul 7 sheets yourself (~$50–$75). Realistic all-in: roughly $260–$415.
Metric check: 3.66 m × 4.88 m = 17.84 m² → ÷ 2.973 = 6.0 → +10% → 7 sheets. Same count, same budget — the currency conversion is the only thing that changes.
How to Keep the Bill Down Without Cutting Corners
- Buy the right grade, not the best grade. CDX for covered sheathing is a feature, not a compromise.
- Plan cuts to reuse offcuts. A layout drawn on paper before you buy can drop waste below 10% — the formula guide covers cut optimization.
- Price the whole lift. At 30+ sheets, lumberyard unit pricing usually wins.
- Don’t shave thickness. Saving $8 a sheet on thinner panels that flex or fail inspection is the most expensive saving in construction.
- Consolidate deliveries. One $75 delivery beats three $50 ones. Estimate the whole job up front — the estimating guide shows how.

Frequently Asked Questions
How much does a 4×8 sheet of plywood cost?
Typically $18–$65 for standard construction grades depending on thickness, $55–$175 for sanded or marine-grade. Regional variation is significant — confirm with local suppliers.
Is 1/2″ or 3/4″ plywood cheaper?
1/2″ is cheaper per sheet (roughly $28–$45 for CDX vs $42–$65 for 3/4″ CDX). But choose by application: 1/2″ suits wall sheathing, 3/4″ suits subfloors. Buying the wrong thickness to save money is a false economy.
What’s the difference in price between CDX and sanded plywood?
Sanded/BC panels typically cost 25–80% more than CDX in the same thickness. CDX is for covered structural work; sanded is for visible or painted surfaces.
How much does it cost to sheath a 12×16 wall?
The wall needs 7 sheets (192 sq ft ÷ 32, +10% waste, rounded up). In 1/2″ CDX at $28–$45 per sheet, that’s $196–$315 in material before tax and delivery.
Why do plywood prices vary so much by region?
Freight distance from mills, local demand, storm rebuilding, tariffs, and lumber futures all move prices. Big-box stores and local lumberyards in the same town can differ 10–20%.
Does buying in bulk lower the price per sheet?
Often, yes — lumberyards commonly discount full-unit (lift) quantities of 30+ sheets by 10–15% versus single-sheet pricing.
Get Your Number
Budgeting plywood is two multiplications: sheets × price per sheet, plus tax and delivery. Get the sheet count from the Plywood Sheet Calculator, match the grade and thickness to the job using the ranges above, and confirm with two local suppliers — prices move, and the only quote that matters is today’s.
