Deck calculator & estimator

Deck size and square footage

The size of your deck is one of the most significant factors in determining the overall decking cost. Naturally, a larger deck will require more materials and labor, increasing the price. Deck costs are often calculated per square foot, so knowing your deck's square footage is essential for creating an accurate estimate.

On average, deck costs range from $15 to $50 per square foot, depending on the materials and complexity of the design.

Here's a more detailed breakdown of average costs based on the deck size:

• Small deck (10x10 feet or 100 sq. ft.): $1,550 to $5,050
• Medium deck (12x24 feet or 288 sq. ft.): $4,400 to $14,500
• Large deck (16x20 feet or 320 sq. ft.): $4,850 to $16,000

Type of deck material

The type of material you choose for your deck will have a huge impact on the total deck installation cost. Here's a quick breakdown of popular decking material options:

• Wood decking: Pressure–treated wood is the most affordable option, costing around $15 to $25 per square foot. Cedar and redwood are slightly more expensive but offer a natural, rustic look.
• Composite decking: This low–maintenance option costs between $25 and $45 per square foot. While pricier upfront, it saves money over time due to its durability and minimal upkeep.
• Exotic hardwoods like Ipe (Brazilian hardwood): If you're looking for luxury, exotic hardwoods can cost $30 to $60 per square foot. These materials are incredibly durable and visually stunning. However, they come with a higher price tag.

Labor costs

Labor costs are a significant part of your deck–building budget. On average, labor accounts for about 50% of the total deck installation cost. Professional deck builders typically charge between $10 and $30 per square foot for labor, depending on the complexity of the project and local rates.

For instance, a simple rectangular deck will cost less to build than a multi–level deck with intricate railings and built–in seating. Additionally, if your project requires extensive site preparation or adherence to strict local building codes, labor costs may increase.

Deck design and features

Your deck design plays a big role in the overall cost. A basic, no-frills deck will be more affordable, while custom features such as stairs, deck railings, outdoor lighting, and pergolas can drive up the price. If you're working with a tight budget, focus on the essentials and save the extras for a future upgrade.

Local building codes and permits

Before you start building, you'll need to check your local building codes and obtain the necessary permits. These regulations ensure your deck is safe and structurally sound. Permit costs vary by location but typically range from $100 to $500. Remember that skipping this step could result in fines or even having to tear down your deck. So, it's worth the investment.

DIY vs. professional installation

If you're considering a DIY approach to save on labor costs, keep in mind that building a deck requires skill and knowledge of local building codes. Rookie mistakes can lead to costly repairs or even safety hazards. Hiring a professional may be expensive but it ensures the job is done correctly and up to code.

What is the average deck removal cost?

The average cost to remove a deck ranges from $500 to $2,000, with most homeowners spending around $1,200 for a standard–sized deck.

Can I save money by building the deck myself?

DIY deck installation can save on labor costs, but it requires the necessary skills and tools. Any mistake can cost you dearly.

Can I finance deck installation?

Some homeowners use home improvement loans to finance deck installation, while others save and pay in cash.
