How to calculate the cost of a deck

Many variables determine the material and labor costs of installing a deck. Not only its size, but the type of wood or material used, its height above the ground, and whether stairs and railings are included.Here’s what you’ll need to know to use our deck cost calculator:
  • Deck dimensions in feet
  • Type of decking material
  • Pressure-treated wood
  • Cedar/redwood
  • Composite
  • Hardwoods, including Ipe
  • Height above ground, if applicable
  • Custom price per square foot (optional)
  • Whether railing and/or stairs are included
Once you click on the Calculate button, you’ll receive a detailed estimate of the cost of the deck, including deck area, material cost, estimated installation cost, railing cost, and stair cost. Factors that will increase the cost of a deck include material selection, elevation, and labor rates.Note that our calculator does not include costs such as ground clearing, excavation, permits, supervision, and overhead/profit.

Example: Cost for a 12’x24’ Composite Deck

Here’s an example showing how our deck material calculator determines the cost of installing a 12' x 24’ composite deck.Calculator inputs:
  • Deck length: 12 feet
  • Deck width: 24 feet

  • Height above ground: 2 feet
  • Include railing and stairs
Based on the inputs above, the calculator estimates the cost for installing the deck at $18,036. Here’s the breakdown:
  • Deck area: 288 square feet
  • Material cost: $2,880 ($10 per square foot)
  • Estimated installation cost: $3.456 ($12 per square foot)
  • Estimated railing cost: $10,500
  • Estimated stair cost: $1,200
