Key Features of the Lowes Deck Calculator
This calculator includes several useful features designed to simplify deck planning.
1. Deck Area Calculation
The tool calculates the total square footage of your deck using deck length and width measurements.
This provides a foundation for estimating material requirements.
2. Board Quantity Estimation
Based on deck dimensions and board width, the calculator estimates the number of boards required to cover the deck surface.
This helps users understand material needs before purchasing supplies.
3. Waste Factor Adjustment
Most deck projects generate some waste due to:
- Cutting boards
- Trim work
- Design adjustments
- Installation errors
The calculator includes a waste percentage option that automatically adjusts board quantities to account for material loss.
4. Cost Estimation
By entering the price per board, users receive an estimated material cost for the decking boards.
This helps create a realistic project budget.
5. Copy and Share Results
Users can save, copy, or share estimates with:
- Family members
- Contractors
- Project partners
- Suppliers
This makes collaboration easier during project planning.
