Interior Finish Calculators

Three flooring materials priced the way they are actually sold: carpet by the roll width, hardwood by the bundle, vinyl plank by the carton — each with its own waste and its own underlayment.

Tile quantity is area divided by tile size and then rounded up twice — once for cuts, once for the box. Wet areas add waterproofing that is priced by the roll, not the square foot.

Kitchens are quoted in linear feet of cabinet run and square feet of countertop, which is why a kitchen estimate rarely matches a floor-area estimate.

Sheet goods and millwork: how many boards a room takes with the mud and tape that go with them, and how much trim a stair or a wainscot run consumes.

Tile, thinset, grout and edge trim for a backsplash.

Base and wall cabinet linear feet, and what they cost.

Square yards of carpet, pad and installed cost.

Countertop area, edge footage and fabricated cost.

Sheet count, mud, tape and screws for a room.

Square footage, waste and installed cost for hardwood floors.

Box count, underlayment, transitions and cost for LVP flooring.

Tile, thinset, grout and waterproofing for a shower.

Tread, riser and nosing counts for finishing a staircase.

Panels, chair rail and baseboard for a wainscoted room.
