Field notes
Frequently asked questions
Why is labor calculated on net area?
This worksheet assumes installers charge for the area covered, while material includes cutting waste. Your contractor may use a different basis.
What belongs in fixed costs?
Use it for measured trim, delivery, disposal, floor preparation, or other known project amounts not already in a per-square-foot rate.
Is tax calculated correctly for my location?
Not necessarily. Taxability of products and services varies. Enter a rate only after checking the rules that apply to the purchase.
