Rough estimate only

This tool is for a simple rectangular ground-level or low deck area only. It may include deck boards, joists or blocking allowance, screws and fasteners, basic framing hardware, weed barrier or gravel allowance if selected, stain or sealer if selected, tool allowance, and cleanup supplies. It does not include multi-level decks, raised decks requiring engineered supports, stairs, railings, ledger attachment design, footing or pier engineering, permits, structural design, demolition of major existing structures, electrical work, hot tub support, waterproof deck systems, or professional labor. Decks can be structural, and local rules or permits may apply. Real costs can change based on local prices, deck size, decking material, framing condition, ground condition, removal needs, stain or sealer choice, tool needs, and cleanup.

Measurement system

Simple rectangular deck area

Estimate a simple ground-level or low rectangular deck or deck surface only. This does not include multi-level decks, raised decks needing engineered supports, stairs, railings, ledger design, permits, demolition of major structures, electrical work, hot tub support, waterproof systems, or professional labor.

Structural and permit warning

Decks can be structural. Check local rules and permits, and call a pro when support, ledger attachment, footings, railings, height, or framing condition is uncertain.

This assumes a simple rectangular deck or deck surface. For L-shapes or multiple areas, estimate each simple rectangle separately.

Project planning note

Review the selected options, site condition, material assumptions, and tool needs before buying supplies. This calculator is meant for rough DIY planning, not a professional quote.

Structural/permit note

This is a rough DIY material planning range, not a structural design. Decks can be structural, and local code, permit, footing, ledger, railing, and support rules may apply.

Recommended materials/tools

  • Pressure-treated wood for about 132 sq ft including 10% waste
  • New simple floating deck
  • New simple frame allowance
  • Deck screws or hidden fasteners, basic framing hardware, blocking allowance, and cleanup supplies
  • Weed barrier or gravel base allowance included
  • No stain or sealer allowance included
  • Basic deck tool allowance included

Basic DIY checklist

  • Confirm the deck is simple, rectangular, ground-level or low, and within local rules before buying materials.
  • Measure length and width, then buy decking with waste for cuts and board selection.
  • Plan framing, blocking, fastener, or inspection work before installing deck boards.
  • Prepare the ground with weed barrier or gravel where appropriate.
  • Lay out boards, fastener spacing, and cuts before installation.
  • Install boards, check fasteners, trim edges, and clean up offcuts.

When to call a pro

  • Decks can be structural, and local rules or permits may apply even for small or low decks.
  • Call a pro for raised decks, ledger attachments, engineered supports, stairs, railings, footings, or structural design.
  • A new floating deck still needs stable support, proper spacing, drainage, and local-code awareness.
  • Do not use this estimate for multi-level decks, raised decks needing engineered supports, stairs, railings, hot tub support, waterproof deck systems, permits, or professional labor.

This is a rough DIY material planning estimate for a simple rectangular deck or deck surface only. It does not include structural design, raised decks, stairs, railings, ledger attachment design, engineered footings, permits, major demolition, electrical work, hot tub support, waterproof deck systems, or professional labor.
