Lowe’s deck lumber prices vary by species, board size, store, and local availability; pressure-treated pine is usually the least expensive option. For a basic 12-by-16-foot deck, expect roughly $700-$1,600 for decking boards and $1,300-$3,000 for decking plus common framing lumber, before fasteners, delivery, and labor.
Use these ranges as planning estimates, then check the local store’s current shelf or online price. Regional supply, board length, and whether the quote includes stairs or railings can change the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Pressure-treated deck boards | $0.70 per linear ft | $1.10 per linear ft | $1.60 per linear ft | Typical 5/4-by-6 boards; grade and length affect price |
| Cedar deck boards | $1.50 per linear ft | $2.30 per linear ft | $3.50 per linear ft | Board grade and local supply vary |
| Deck lumber for 12-by-16-foot project | $1,300 | $2,100 | $3,000 | Decking and basic framing; excludes labor and railings |
| Delivery | $0 | $79 | $150+ | Depends on store, distance, and order size |
What Lowe’s deck lumber costs for a 12-by-16-foot deck
A 192-square-foot deck using pressure-treated pine commonly needs about 450-550 linear feet of decking after allowing for cuts and waste. At roughly $0.70-$1.60 per linear foot, boards may cost $315-$880; wider price differences reflect board quality, length, and local pricing. Higher-grade cedar can put the decking-only bill around $675-$1,925.
Framing lumber adds a substantial amount. A basic platform may need joists, beams, rim boards, and posts, with a combined lumber allowance of about $600-$1,500. A practical lumber-only budget is $1,300-$3,000 for pressure-treated decking and framing.
Assumptions: 12-by-16-foot platform, standard residential framing, pressure-treated pine, ordinary access, and 10%-15% cutting waste; no stairs, railing, permits, or labor.
How decking boards and framing shape the quote
Prices below are broad retail planning ranges, not guaranteed Lowe’s quotes. Exact shelf prices can differ by ZIP code and product availability.
| Material or task | Typical price | Common quantity or unit | Budget note |
|---|---|---|---|
| Pressure-treated 5/4-by-6 decking | $8-$19 | 12-foot board | About $0.70-$1.60 per linear foot |
| Cedar 5/4-by-6 decking | $18-$42 | 12-foot board | Grade and availability drive the spread |
| Pressure-treated 2-by-8 joist | $15-$32 | 12-foot board | Longer lengths typically cost more |
| Posts and beam lumber | $20-$65 | Common 4-by-4 or 6-by-6 piece | Size, treatment, and length matter |
| Deck screws and connectors | $60-$220 | Small-to-medium deck allowance | Fastener type and quantity vary |
Deck-board prices alone do not represent the full lumber package. Joists, beams, posts, blocking, and hardware should be counted from the actual design rather than estimated from square footage alone.
Board length, joist spacing, and lumber grade change totals
Decking choice is one of the clearest price levers. Pressure-treated pine generally costs less than cedar, while premium grades and selected appearance can raise the board price. A 16-foot board may cost more than a 12-foot board but can reduce seams and offcuts when the deck dimensions suit it.
Framing specifications matter, too. Joists spaced 12 inches on center use more lumber than joists spaced 16 inches on center; the required spacing depends on the decking product, joist span, and local code. A deck higher than 30 inches above grade may require guardrails, while a longer span or heavier design can call for larger framing members.
Allow 10%-15% extra board length for cuts, defects, and layout waste. Complex angles or diagonal decking can require roughly 15%-20% extra, increasing material cost beyond a simple rectangular layout.
How delivery, stairs, and railings add lumber charges
A lumber order that fits in a vehicle may avoid a delivery fee, but full-length boards and framing bundles often need store delivery. A planning allowance of $79-$150 or more is reasonable for many orders, though local fees and distance determine the actual charge. Check whether unloading is included and whether the delivery truck can reach the site.
Stairs and railings are often excluded from basic deck estimates. A short stair run can add roughly $150-$500 in lumber and hardware, depending on width and design. Wood railing may add about $20-$60 per linear foot for materials; balusters, posts, and more decorative designs increase the price.
Confirm the quote covers every required component before comparing totals. Add blocking, ledger fasteners, post bases, flashing, and stair framing where the plan calls for them; these items can be easy to overlook in a boards-only shopping list.
Which project specifications raise the lumber bill fastest
Deck area changes board quantity nearly in proportion: a 300-square-foot deck typically needs about 56% more decking than a 192-square-foot deck, before layout adjustments. Height can add posts, bracing, stairs, and guardrails, so elevated decks often cost more than low platforms of the same size.
Span and load requirements influence joist dimensions and spacing. For example, changing from 2-by-8 joists to 2-by-10 joists increases lumber cost per member, and a design requiring 12-inch spacing uses about one-third more joists than 16-inch spacing across the same width. Local code and an approved plan should govern those choices.
Price the design’s actual dimensions and framing schedule, not just its square footage. Soil conditions, ledger attachment, unusual angles, and board lengths can also change quantities or require added material.
Regional Lowe’s pricing can differ by roughly 10%-25%
Retail lumber prices are store- and market-specific. High-demand metro areas, regions with limited supply, and places where treated lumber or cedar is less readily stocked may run about 10%-25% above a lower-cost market. Rural stores can have lower shelf prices in some areas but higher delivery charges or fewer long-board options.
Seasonal demand can affect availability and promotions, especially during spring and early summer. Rather than assume one national Lowe’s price, compare the same SKU and board length at nearby stores and confirm whether the quoted item is in stock.
Use local SKU pricing for the final estimate. Online prices may vary by ZIP code, and listed prices can change before pickup or delivery.
Three sample lumber budgets for different deck scopes
These examples illustrate material-only budgets using common U.S. retail ranges. They exclude labor, permits, demolition, and major site work; actual takeoffs depend on the plan and selected products.
| Deck scope | Board estimate | Framing and hardware | Approximate total |
|---|---|---|---|
| 10-by-12-foot low platform, treated pine | About 300-350 linear ft; $210-$560 | $450-$850 | $660-$1,410 |
| 12-by-16-foot platform, treated pine | About 450-550 linear ft; $315-$880 | $900-$2,120 | $1,215-$3,000 |
| 12-by-16-foot platform, cedar boards | About 450-550 linear ft; $675-$1,925 | $900-$2,120 | $1,575-$4,045 |
Assumptions: Standard rectangular layouts, 10%-15% waste, ordinary framing, and no railing or stair materials unless specified. Totals are rounded planning ranges.
Lower the Lowe’s deck lumber total without weakening the frame
Keep the shape rectangular and choose board lengths that limit offcuts. Compare treated pine with cedar by total installed scope, not only the cost per board. A straightforward pattern and standard board dimensions can reduce waste and simplify the cut list.
Before buying, compare the same lumber grade, dimensions, treatment, and length across local stores. Ask for a written takeoff or build a materials list from the plan, then add a measured waste allowance rather than purchasing extra bundles without calculation. Bundle delivery with other project materials if fees are charged per order.
Save on appearance choices and delivery logistics, not on code-required framing or fasteners. Avoid upgrading to premium boards where standard stock meets the design, and verify structural sizes with local code or a qualified professional.
