Takeoff
Interior and exterior finish calculators
How many tiles, sheets, posts, squares of siding, boxes of flooring, bags of grout, and bags of insulation. Each takeoff shows the waste next to the geometry.
Tile Calculator
Tile calculator with straight, diagonal, and herringbone waste. Boxes, thinset, and grout from the joint size.
Drywall Calculator
Drywall calculator for sheets, joint tape, mud, and screws. Openings come off the area before the waste percent.
Fence Calculator
Fence calculator for posts, rails, pickets, gates, and concrete bags per post hole. Bag yields match the concrete calculator.
Siding Calculator
Siding calculator for squares, vinyl panels, fiber-cement planks, starter, J-channel, and corners. Manufacturer coverage and exposure win.
Flooring Calculator
Flooring calculator for square feet, boxes of plank, carpet square yards, and a roll layout. Box coverage and the installation guide win.
Grout Calculator
Grout calculator for pounds and bags from tile size, joint width, and joint depth. The manufacturer’s coverage chart wins.
Insulation Calculator
Insulation calculator for batt packages and blown-in bags, with ENERGY STAR attic R-values. An estimate, not an energy audit or a Manual J.
How these calculators work
Tile starts from the floor area and the tile size. Straight, diagonal, and herringbone each carry a planning waste percent you can change. Boxes round up. Thinset and grout bags use a coverage you type, because the chart on the bag is the one that matters. The joint volume is shown beside that, from the width and the depth of the grout line.
Drywall counts 4 × 8 or 4 × 12 sheets after openings and waste. Tape assumes the sheets hang in a grid, so the seams are the joints between those sheets. Mud and screws are planning rates. A fence is posts at the spacing you set, rails, pickets on the length that is not a gate, and concrete in each hole. The hole is a cylinder minus the dressed post, and the bag yield is the same Quikrete figure as the concrete calculator. A gate hangs on the line posts. It does not add a post.
Siding counts squares, panels or planks, starter, J-channel, and corner posts. A square is 100 square feet. Coverage is the piece length times the exposure. The manufacturer’s sheet wins.
Flooring counts net area, full boxes, and a carpet roll both ways. Waste starts at 10 percent for a straight lay. The coverage on the carton wins. Grout is the joint volume times a density checked against a Custom Building Products chart. The chart on the bag still wins. Insulation counts batt packages from the package coverage, or blown-in bags from the chart on the bag. The R-value table is an estimate, not an energy audit.
