How the numbers work
- Area: 15 × 12 = 180 sq ft.
- With waste: 180 × 1.1 = 198 sq ft ÷ 22 sq ft per box = 9 boxes, 198 sq ft.
- Underlayment: 180 ÷ 100 sq ft per roll, rounded up = 2 rolls.
- Quarter round: 54 ft perimeter × 1.1 ÷ 8 ft = 8 pieces.
- Cost: 198 × $3.00 + 2 × $30.00 + 8 × $8.00 = $718.00.

What changes the cost
- Flooring grade
- Flooring is 83% of this list at $3.00 a square foot. Thicker laminate, higher wear ratings, vinyl plank and engineered hardwood are priced differently; the total scales with the price per square foot you enter.
- Underlayment
- Planks with an attached pad usually skip separate underlayment, which saves $60.00 here. Over concrete, use an underlayment with a vapor barrier.
- Waste and layout
- 10% suits a straight lay in a regular room. Diagonal runs take about 15% and herringbone about 20%; at 15% this room needs 10 boxes.
- What is not counted
- Transitions and thresholds, stair nosing, door jamb undercutting, subfloor leveling compound and removal of the old floor.
- Labor versus DIY
- These are register prices for doing the work yourself. A contractor's bid adds labor, equipment, overhead, permit fees where they apply, and markup on materials, so it will run well above this figure. Get two or three written bids against the same plan and compare the material lists line by line. Click-lock laminate is one of the friendlier DIY floors. A flat subfloor decides how it turns out.
- Regional prices
- Default prices are ballpark U.S. home-center figures. Expect them to differ by region, season, brand and grade. Enter your store's prices in the calculator and every quantity on this page reprices.
