TimberTech Decking Calculator
Planning a deck project without proper calculations can lead to wasted money, material shortages, or unnecessary delays. Whether you’re a homeowner, contractor, or DIY enthusiast, estimating the correct number of decking boards and total project cost is one of the most critical steps before construction begins.
The TimberTech Decking Calculator is a powerful and easy-to-use tool designed to give you accurate material estimates, cost breakdowns, and waste calculations in just seconds. Instead of guessing or manually calculating measurements, this tool helps you plan smarter, save money, and avoid costly mistakes.
What Is the TimberTech Decking Calculator?
The TimberTech Decking Calculator is an online estimation tool that helps you calculate:
- Total deck area
- Number of decking boards required
- Linear feet of decking material
- Additional boards needed for waste
- Total material cost
- Fastener cost
- Overall project budget
- Cost per square foot
By entering a few basic details about your deck and chosen board options, the calculator instantly generates a complete material and cost estimate tailored to your project.
Why Accurate Deck Calculations Matter
Decking projects involve precision. Even small miscalculations can result in:
- Buying too few boards and stopping work midway
- Overbuying materials and wasting money
- Incorrect spacing that affects drainage and durability
- Underestimating total cost
This calculator removes the guesswork by using real-world construction logic such as board spacing, waste factors, and coverage per board.
How to Use the TimberTech Decking Calculator
Using the calculator is simple and beginner-friendly. Follow these steps:
1. Enter Deck Dimensions
Input the length and width of your deck in feet. This determines the total deck area.
2. Select Board Length
Choose the board length that best matches your layout, such as 12, 16, or 20 feet.
3. Choose Board Width
Select your preferred board width. Wider boards cover more area but may change the number of rows required.
4. Select Board Spacing
Spacing affects drainage and expansion. You can choose from no gap or standard spacing options like ⅛″, 3⁄16″, or ¼″.
5. Set Waste Factor
Every project needs extra material for cuts, errors, and future repairs. Select a waste percentage based on your deck pattern:
- Standard layouts: lower waste
- Diagonal or complex designs: higher waste
6. Enter Board Cost
Provide the price per board to calculate accurate material costs.
7. Add Fastener Cost
Fasteners are essential and often forgotten. This tool includes fastener costs per 100 square feet for better budgeting.
8. Click Calculate
The tool instantly displays a full material and cost breakdown.
Example Deck Calculation
Imagine you’re building a deck with the following details:
- Deck size: 20 ft × 12 ft
- Board length: 16 ft
- Board width: 5.5 inches
- Spacing: 3⁄16 inch
- Waste factor: 10%
- Cost per board: $45
- Fastener cost: $25 per 100 sq ft
The calculator will instantly show:
- Total deck area in square feet
- Exact number of boards needed
- Extra boards added for waste
- Linear feet required
- Decking material cost
- Fastener cost
- Total estimated project cost
- Cost per square foot
This allows you to plan your purchase confidently before visiting the store.
