- Enter deck dimensions — measure the width and depth of your planned deck in feet. A 12x16 deck (192 sq ft) is a common starter size.
- Select deck height — ground-level decks are cheapest to build. Elevated decks need more footings, posts, and labor, increasing costs 15-50%.
- Choose decking material — pressure-treated wood (most common, cheapest), cedar (natural beauty), composite (low maintenance), PVC (premium), redwood (luxury), or set a custom cost per sq ft.
- Set labor cost — adjust the labor rate per sq ft for your region. Elevated decks and premium materials cost more.
- Toggle options — include railings, stairs, old deck removal, and a 10% waste factor as needed.
- Click Calculate — see total cost, cost per sq ft, and a detailed breakdown.
📌 5 tips for building a deck
- ✓ Get 3+ quotes from licensed contractors. Decking prices vary 30-50% between contractors for the same materials. Ensure each quote includes footings, framing, decking, railings, stairs, permits, and cleanup in writing.
- ✓ Build in spring or early fall. Decking needs temperatures above 50°F (10°C) for proper board spacing and sealing. Summer is peak season with peak prices; off-season discounts of 10-15% are common in late fall and winter in mild climates.
- ✓ Don\u2019t skip the footings. Proper concrete footings below the frost line prevent heaving and settling. A 12x16 deck typically needs 6-9 footings depending on local codes. Skipping footings to save $500 can cost $5,000+ in repairs within 5 years.
- ✓ Consider composite for low maintenance. Composite decking costs 2-3x more upfront but saves $200-$500/year on staining, sealing, and board replacement. Over 15 years, composite often costs less total than wood when maintenance is included.
- ✓ Order 10-15% extra material. Waste from cutting boards to length, notching around posts, and angled corners adds up fast. Running short mid-project means delivery fees and potential color mismatches from different production batches. Leftover unopened materials can usually be returned.
