What waste factor should I use?

For straight-lay rectangular rooms use 5–8%. For diagonal or herringbone patterns, or rooms with many cuts (L-shapes, closets), use 10–15%. Stone and large-format tiles often need 10% minimum due to breakage risk.

Does the calculator include underlayment or subfloor costs?

No. The material cost field covers only the flooring surface. Add underlayment, adhesive, or subfloor prep costs separately in the notes field, or factor them into your labor rate.

What is a typical labor rate for flooring installation?

Labor rates vary widely by region and flooring type. Laminate and vinyl plank typically run $1.50–$3 per sq ft. Hardwood runs $3–$6. Tile (especially floor tile) runs $4–$8 per sq ft. Always get local quotes.

How do I handle an L-shaped or irregular room?

Divide the room into rectangles, calculate each section separately, then add the results together. Alternatively, enter the total square footage directly in the square feet input mode.

Is sales tax included in the estimate?

No. Tax rates vary by location. Multiply the material cost by your local tax rate and add it manually to get the final materials budget.

Can I use this for outdoor flooring like decking?

Yes. Enter the deck dimensions and use the cost per square foot for your decking material. The waste factor and labor rate fields work the same way.
