Add your rooms to find out how many boxes of laminate, vinyl plank, hardwood, or engineered flooring you need — with a waste factor and total cost.
Flooring is sold by the box, and each box covers a set number of square feet. The method is: add up the area of every room, add a waste allowance, then divide by the box coverage and round up. This calculator handles multiple rooms at once and works out the boxes and total cost for you — so you buy enough in one trip without massively overbuying.
1. Room area = length × width, for each room.
2. Total area = sum of all rooms.
3. With waste = total area × (1 + waste % ÷ 100).
4. Boxes = area with waste ÷ box coverage, rounded up.
Add 10% for a standard straight layout and 15% for diagonal installs or rooms with lots of closets, angles, and doorways where you'll make more cuts. It's worth keeping a leftover plank or two as well — flooring colors shift slightly between production runs, so a future repair from a fresh box may not match.

Box coverage varies a lot between products and brands, so don't rely on a generic number. Find the square footage printed on the box (or the product page) and enter it above for an accurate count.
