How to calculate laminate flooring
The formula: boxes = ceil( area × (1 + waste) ÷ box coverage )
- Measure the room length and width in feet and multiply for the floor area.
- Check the coverage printed on the laminate box — often about 20 sq ft.
- Add 10% for cuts and waste (15% for diagonal or herringbone layouts).
- Divide the area by the box coverage and round up. Buy a spare plank or two for repairs.

How much does laminate flooring cost?
Laminate flooring costs about $1–$3 per square foot for the planks, plus $0.20–$0.50 for underlayment. Installed by a pro, expect $3–$7 per square foot including labor. For a 12×12 room (144 sq ft), that's roughly $150–$500 in materials, or $430–$1,000 installed.
What drives the cost
- Plank quality — thickness, AC wear rating, and water resistance.
- Underlayment (sometimes pre-attached) and a moisture barrier.
- Pattern and room cuts — diagonal layouts and many doorways add waste.
- Subfloor prep, transitions, and trim.
DIY vs. hiring a pro
Click-lock laminate is one of the most DIY-friendly floors — no glue or nails, just a saw, spacers, and a tapping block. Most of the pro price is labor you can skip. Add 10% for waste (15% for diagonal layouts), let the planks acclimate in the room for 48 hours, and leave an expansion gap at the walls.
