    What Is This Calculator?

    The Flooring Cost Calculator — Covers US floors — hardwood, laminate, vinyl, carpet and tile with grout and waste.

    What Does It Calculate?

    • Floor area in square feet
    • Boxes or rolls with waste
    • Grout and adhesive

    How to Use the Calculator

    1. Measure Room 12x10 ft, height 8 ft — use feet for length/width and inches for thickness where typical.
    2. Enter values and select units. The calculator converts to feet before calculating (inches /12, yards x3).
    3. Adjust waste % and optional price, then click Calculate. Results show with waste included.
    4. Use Reset to clear and try another size.

    Formula & Engineering Methodology

    Total = quantity × allowance factor × unit price × (1 + material tax / 100) + delivery + labor.

    • Area — Length x Width in ft2

    All units convert to exact standard engineering dimensions (NIST SP 811) before calculation to ensure consistency between US Customary and Metric measurements.

    Worked Example

    Example: Room 12x10 ft, height 8 ft

    STEPVALUE
    Wall area2x(12x8)+2x(10x8)=352 ft2
    Less openings-21 ft2 door =331 ft2
    Gallons @350 ft2/galceil(331/350)=1

    Construction Information

    Material: Tile 12x12 in = 1 ft2, 6.8 per ft2 with grout. Hardwood 20 ft2 per box. Carpet 12 ft wide rolls.

    • Measure longest x widest; split L-shapes into two rectangles and add.
    • Compact subgrade — soft spots add thickness.
    • For structural sizing (beams, headers, rebar) verify with a professional per local code.

    Material Information

    Tile 12x12 in = 1 ft2, 6.8 per ft2 with grout. Hardwood 20 ft2 per box. Carpet 12 ft wide rolls.

    Waste & Overages

    Add 10% for straight, 15% for diagonal or large tile. Pattern adds 20%.

    Practical Tips

    • Acclimate wood 72 hours
    • Stagger joints 6 in

    Common Mistakes

    • Not adding waste for diagonal — short 15%
    • Forgetting grout joint — count off

    Assumptions & Engineering References

    • Quantity and quoted unit price must use the same unit. Tax applies to materials only in this model; local treatment of services and delivery may differ.
    • Use a separate calculation for each material line and add the totals.
