How to Calculate Deck Installation Cost By Using Our Calculator

Follow this step-by-step walkthrough to get a realistic quote for your new deck:

Step 1: Input Deck Dimensions

Enter the total square footage of your deck design. Use a layout guide if your deck is L-shaped or wraps around a corner.

Step 2: Choose Decking Material

Select from:

  • Pressure-treated wood
  • Redwood or cedar
  • Composite boards (Trex, TimberTech, etc.)

Material cost and lifespan will adjust automatically.

Step 3: Set Deck Height

Select ground level, raised, or multi-level deck. Higher decks increase the need for posts, railing, and stairs.

Step 4: Add Railing & Stairs

Enter how many linear feet of railing are needed and the number of stair treads or full flights.

Step 5: Select Joist and Frame Type

Toggle between wood or metal framing. Metal framing adds cost but increases lifespan and fire resistance.

Step 6: Configure Footings & Supports

Choose standard concrete piers or toggle for slope reinforcement if building on a hillside.

Step 7: Choose Board Layout & Finish

Select layout type: parallel, diagonal, or herringbone. Decorative layouts increase cutting labor.

Step 8: Add Hardware Options

Toggle hidden fasteners, post anchors, or stainless hardware for coastal builds.

Step 9: Enable Permit & Inspection Fees

Check this if required by your municipality. Most California decks require a plan review.

Step 10: Input Labor Rate

Use the average crew rate or enter your contractor’s hourly quote.

Step 11: Select Maintenance Plan

Choose:

  • No maintenance (composite)
  • Annual sealing and wash (wood decks)
  • Full service (power wash, reseal, hardware check)

Step 12: Click “Calculate”

The tool provides:

  • Total estimated range
  • Cost breakdown by labor, materials, permits, and extras
  • Optional PDF export for contractor comparison
