Flooring Installation Cost Calculator
Add each room to estimate material (with waste), labor, prep, removal, underlayment, and trim for your new floor.
Add a row per room. For irregular rooms, enter an equivalent length × width that matches the measured area.
Leave 0 to use the material default.
Extra material for cuts. Diagonal / herringbone patterns need more; tile typically higher than carpet.
Adds $1.50/sq ft for tear-out and disposal.
Adds $0.55/sq ft of underlayment / padding.
Leave 0 to use the material default.
How We Calculated This
- Net area = Σ (room length × room width) across all rooms.
- Purchase area = net area × (1 + waste % ÷ 100).
- Flooring material = purchase area × material $/sq ft.
- Installation labor = net area × labor $/sq ft (labor billed on finished area, not waste).
- Underlayment (if on) = net area × $0.55/sq ft.
- Subfloor prep = net area × prep rate (none $0, minor $0.75, self-level $2.25 per sq ft).
- Remove existing floor (if on) = net area × $1.50/sq ft.
- Trim (if > 0) = baseboard linear ft × $3.50/lin ft.
- Total = material + underlayment + labor + prep + removal + trim + contingency.
- Cost per sq ft = total ÷ net area.
Assumptions
- Waste % varies by material and install pattern; expose a single editable input.
- All $/sq ft prices are editable planning assumptions, not verified national averages.
- Labor is charged on net (finished) area, not the waste-inflated purchase area.
What's excluded
- Subfloor structural replacement
- Moisture mitigation
- Stair treads
- Furniture moving
