About this calculator

Flooring cost has three components: material (varies wildly by type), underlayment (often required), and installation. This calculator totals them per room with a configurable waste percentage for plank and tile patterns.

Material price ranges (per sq ft)

  • Vinyl plank (LVP) — $2–6. Waterproof, easy DIY install, fine for rentals.
  • Laminate — $1.50–5. Cheap and durable but not waterproof.
  • Engineered hardwood — $4–12. Real wood top layer over plywood. Good for most living spaces.
  • Solid hardwood — $6–15. Sand-able multiple times. Heritage-grade.
  • Tile (porcelain, ceramic) — $2–10 material, $5–15 install (labor-intensive).
  • Natural stone (marble, slate) — $10–40+. Expensive material and install.
  • Carpet — $1–8 + pad. Cheap and comfortable; needs replacement every 5–10 years.

Waste planning

Straight-pattern plank or sheet: 7–10% waste. Diagonal layouts, herringbone, or odd-shaped rooms: 12–15%. Large-format tile with random offset: 10–15%. Always order one full extra box for future repairs — dye lots vary and you may not find a match later.

Installation cost factors

DIY-friendly: floating click-lock LVP/laminate (~$0–1/sq ft if you self-install). Glue-down or nail-down hardwood: $3–6/sq ft labor. Tile: $5–15/sq ft, more for intricate patterns. Carpet: $0.50–2/sq ft. Demolition of old flooring is extra ($1–3/sq ft).

The hidden costs

  • Subfloor prep — leveling, repair, moisture barrier. $1–3/sq ft.
  • Underlayment — required for most floating floors. $0.25–1/sq ft.
  • Transitions and trim — quarter-round, T-mold, thresholds. $1–3 per linear foot.
  • Disposal — Dumpster rental for ripped-out flooring.

Frequently asked questions

What’s the cheapest durable flooring?
Vinyl plank (LVP). $2–4/sq ft material, easy DIY install ($0/sq ft labor), waterproof, lasts 10–20 years in residential. Doesn’t look as premium as hardwood but holds up better in kids/pets households.
Is engineered hardwood as good as solid?
For everyday durability, yes — often better in basements and below-grade applications because it tolerates moisture variation. Solid wood can be sanded and refinished 4–6 times over its life; engineered can be refinished 1–2 times depending on top-layer thickness.
How long does flooring installation take?
DIY click-lock plank: 1 weekend for a 200 sq ft room. Pro install: 1–3 days for a typical residential job. Tile: 2–4 days depending on prep and grout cure time. Plan for the room being unusable during work.
Can I install over existing flooring?
Floating floors (LVP, laminate, engineered hardwood) can usually go over existing tile, vinyl, or hardwood if it’s smooth and level. Carpet usually has to come up first. Always check manufacturer warranty requirements.
