Formula Used
Let Ai=Li×Wi be each room area in the selected unit.
Waste factor per room is wi = 1 + (waste%/100), or default if blank.
- Net install area:
Anet = Σ(Ai × wi) - Materials:
Σ(Ai × wi × materialRatei) - Labor:
Σ(Ai × wi × laborRatei) - Extras (area-based):
(underlayment + adhesive + tearout + subfloor + finish) × Anet - Extras (discrete):
delivery + furniture + stairsCount×stairsRate + trimLen×trimRate - Subtotal: materials + labor + extras − discount
- Contingency:
subtotal × contingency%(added) - Tax:
(subtotal + contingency) × tax%(added) - Total:
subtotal + contingency + tax
Assumptions: labor priced on net area; tax applies to subtotal plus contingency. Adjust rates to match local practice.
