Hardwood Flooring Cost Calculator

Solid white oak, prefinished, nailed down over a sound subfloor computes to about $14,720 ($11,776–$19,872) at national-average rates — roughly $15 per square foot. HomeGuide's 2025 installed band is $9–$25/sf and Angi's guides run $6–$25/sf, so species and grade choice swings the same 1,000 sq ft by four figures.

Refinishing, almost every time the floor is structurally sound: a full sand-and-refinish of 600 sq ft computes to about $3,000 versus $6,888 for new engineered red oak — refinish runs roughly 40–45% of replacement, before tear-out and disposal costs. Replace instead when boards are water-damaged or cupped, the wear layer is gone, or the floor has already been sanded to the nails.

About 20% at the same species: engineered carries a thinner wear layer of the same wood, so it prices at roughly 0.8× the solid material cost — white oak lands near $12.80/sf installed engineered vs $14.70 solid in this model, matching HomeGuide's installed bands ($9–$20 engineered, $11–$25 solid). Below grade or over concrete, engineered is not just cheaper — it is the correct product.

HomeGuide puts the finishing premium at $2–$5 per square foot; this calculator adds the midpoint, split between sand-and-coat labor and stain/finish materials. You get a seamless, perfectly flat surface and any stain color, but the crew is in your house for several more days and the floor cures off-limits — prefinished floors are walkable the day they are installed.

Yes. HomeGuide ranks nail-down cheapest, then glue-down, with floating the most involved; this model adds about 20% labor for glue (adhesive plus trowel work) and 10% plus an underlayment line for float. The real constraint is the subfloor: nail-down needs a wood subfloor it can bite into, while slabs force glue-down or floating engineered.

A two-person crew lays 300–500 sq ft of prefinished board per day, so a 600–1,000 sq ft main floor is typically 2–3 days of work — plus the step people forget: the bundles should acclimate in the room for 3+ days (longer in very dry or humid weather) so the boards reach the space's moisture content before they are fastened; skipping acclimation is how gaps and cupping start. Site-finished floors add one to two days of sanding and coats, then 2–3 days of cure before furniture returns; prefinished floors are walkable the evening they are laid. Any tear-out you select in this calculator comes first and is usually same-day for carpet.

Tear-out unless you select it — on the 600 sq ft reference floor, removing carpet adds roughly $690 at national-average labor and hard surfaces about $1,500; a subfloor patch runs about $4 per square foot of soft spots, so probe doorways and under the dishwasher before you sign. Also excluded: replacing damaged joists (HomeGuide: $350–$1,000 per joist), baseboards and shoe molding, transition strips at doorways, furniture moving, and slab moisture-mitigation coatings — all common add-ons that show up as change orders when they were never budgeted.

Straight-lay installs waste about 8% to cutting — already included in the board line. Diagonal and herringbone layouts push waste to 15–20% and demand experienced labor: HomeGuide prices parquet and herringbone installs at $13–$40 per square foot installed, which is why this tool's straight-lay numbers will read low for pattern work.
