Length, wood grade, and treatment level are the biggest price levers for 20 ft posts. A higher grade 6×6 with extra penetration during pressure treatment costs more but lasts longer. Per-foot premiums typically range from $2 to $8 beyond basic stock, depending on moisture content and regional supply. Assumptions: standard residential use; no rare species; typical water-based preservative.
Delivery distance and labor intensity frequently determine final pricing. Short distance delivery adds a modest fixed charge; long-haul routes or multiple trips push cost higher. Labor can scale with site access, backfill needs, and whether posts require notching or bracing.
Regional differences can shift prices by roughly 15%–35% between markets. Coastal zones often face higher delivery costs, while rural areas may have lower labor competition and faster turnaround. The ranges below reflect typical regional swings for a 20 ft 6×6 post with standard installation. Assumptions: consistent treatment method and standard supplier margins.
| Region | Post Price | Delivery | Labor | Notes |
|---|---|---|---|---|
| Northeast | $60-$95 | $40-$90 | $120-$260 | Higher urban transport cost |
| Central | $50-$80 | $25-$70 | $100-$230 | Balanced pricing |
| South | $45-$75 | $20-$60 | $90-$210 | Lower cold-weather handling |
| West | $55-$100 | $30-$85 | $110-$240 | Remote areas can raise costs |
Per-post pricing versus bulk discounts change the average price per unit. When ordering 20 or more posts, suppliers commonly offer a per-post reduction of 5%–12%. Bulk orders may also reduce delivery costs per post. Assumptions: standard drive-by delivery, no special handling equipment required.
Smart choices can trim costs without sacrificing structural integrity. Consider shorter lead times, opt for standard moisture content, choose common pressure-treated species, and limit add-ons like heavy brackets. Scheduling during off-peak seasons, bundling orders, and comparing multiple quotes can unlock price relief. Assumptions: typical residential project, standard site access.
Three sample quotes show how factors shift totals.
- Scenario A: 10 posts, 20 ft each, standard grade, no delivery surcharge, basic backfill. Materials $700; Labor $1,200; Delivery $60; Total $1,960.
- Scenario B: 25 posts, 20 ft, higher-grade pressure treatment, remote delivery, minor site prep. Materials $1,900; Labor $3,400; Delivery $240; Total $5,540.
- Scenario C: 12 posts, 20 ft, bulk discount applied, local delivery included. Materials $780; Labor $1,300; Delivery $0; Discount $60; Total $2,020.
Per-post pricing typically falls in a narrow band with regional variation. A single 20 ft 6×6 post commonly ranges from $40 to $110, with delivery and labor added on top. For budgeting, use the per-post price plus a fixed delivery and installation estimate per site.
