Assumptions
Flooring is sold by the box, not the square foot, and every box only covers its labeled area. Take the exact room area, add a waste percentage that matches your install pattern, then divide by the box coverage and round up to the next full box. Even a small remainder means you need to open another box.
Most laminate and floating floor products need underlayment for sound and cushion. On slab-on-grade concrete you also need a vapor barrier under the underlayment, or a product that includes it, or the flooring can cup from ground moisture. Vinyl plank often has attached pad; do not stack pads.
Once installed, keep at least one full unopened box in a closet. Manufacturers change dye lots and even discontinue lines within a few years, and matching a repair section later is often impossible. That extra box is the cheapest insurance you can buy.
