Why this rating: A click floor is accessible once moisture, flatness, and transitions are resolved.
Applies to: A simple dry room using the selected product system.
Get help when: Stop for moisture, unknown old flooring, soft subfloors, or installation conditions outside product limits.
A planning guide, not a safety certification. Conditions at your home can change the difficulty. Ratings are independent of contractor relationships.

PermitsNone
Permits & safety: No permit needed. Wear knee pads and keep fingers clear when scoring, snapping, or saw-cutting planks.
Plan the whole project as you go. Add each calculator result to a named project, then edit quantities and supplier prices, check off purchases and stages, and export CSV, print/PDF, or JSON.
1Acclimate the planks
Lay the unopened boxes flat in the room for at least 48 hours so the flooring reaches the room’s temperature and humidity before you lock it in.
2Prep the subfloor
The subfloor must be clean, dry, and flat to within ~3⁄16” over 10 ft. Grind high spots and fill lows with self-leveler — an uneven base is the #1 cause of failed click joints.
3Add underlayment if needed
Install foam underlayment (and a 6-mil vapor barrier over concrete) only if it isn’t already attached to the planks. Never stack two pads — it makes the floor spongy and stresses the joints.
4Plan the layout and expansion gap
Set plank direction, balance the first and last rows, and stagger end joints 6–12”. Leave a ¼–⅜” expansion gap at every wall and fixed object, kept continuous all the way around. Buy 5–10% extra for waste.
Measuring a room — multiply length × width for each rectangle, break odd shapes (closets, bays) into separate rectangles and add them, then add 5–10% for cuts and waste.
5Click the planks together
Angle each plank’s tongue into the groove and lower it until it clicks, tapping the long seam tight with a block and snugging end joints with a mallet, row by row. Rip the last row to width and pull it tight with a pull bar. The calculator sizes your flooring and underlayment.

How this estimate works
Room area × (1 + waste % ÷ 100) gives coverage needed. Divide by box coverage and round up to whole boxes. Cost uses whole boxes × box coverage × your price per sq ft. Start at 10% waste for a simple layout; complex cuts may need more.
Optional underlayment rounds up to 100-sq-ft rolls at a sample $35 per roll. Turn it off for attached-pad products or when separate foam is not permitted. Trim, transitions, adhesives, removal, and subfloor repairs are not included; edit supplier prices in My Projects.

6Add transitions and trim
Install T-moldings at doorways and large spans, then cover the expansion gap with baseboard or quarter-round nailed to the wall, never the floor, so the floor can still move. The calculator sizes the baseboard run.

Laminate has a wood-fiber core with a printed layer and is water-resistant; LVP is all-plastic and waterproof, so LVP suits kitchens, baths, and basements.
Do I need underlayment?
Only if it isn’t already attached to the planks. Many planks ship with bonded backing — adding a second pad makes the floor spongy and can crack the joints.
How big should the expansion gap be?
¼” at every wall for a normal room, up to ⅜–½” on large floors. It must be continuous around the whole perimeter.
How much extra flooring should I buy?
Order 5–10% over your square footage for cuts and mistakes — 10% for diagonal patterns or rooms with lots of corners.
