Concrete Calculator Pro

Concrete, tile, paint & gravel calculator. Yards, bags, fast jobsite estimates.

Concrete Calculator Pro is a construction calculator and material estimator for contractors, remodelers and homeowners. Pouring a slab, tiling a bathroom, painting a bedroom or spreading gravel — get the quantity in cubic yards, bags and square feet before you drive to the supply yard.

8 JOBSITE CALCULATORS
• Concrete slab — length x width x thickness in feet and inches, converted to cubic yards, 60 lb or 80 lb bags and mixing water
• Column and footing — round sonotube or rectangular forms, any count
• Tile — room area minus openings, tile size, adjustable 5-15% waste, tiles and boxes to order
• Paint — wall area with doors and windows deducted, coverage per gallon and number of coats, gallons plus a can-size shopping list
• Wallpaper — perimeter, ceiling height and pattern repeat converted to rolls
• Bricks and block — wall area, unit format and joint thickness to units and mortar bags

CONCRETE CALCULATOR AND PRO
The standard version includes the concrete slab, paint, tile and gravel calculators.

Contractors use it to price a driveway pour, a patio slab or a footing before quoting. DIYers use it so they do not end up with six extra bags of ready-mix in the garage, or three boxes of tile short on a Sunday afternoon. Type the dimensions, read the yardage.

Estimates are indicative and intended for planning. Always confirm quantities, mix design and structural requirements with your supplier or engineer, and follow local building codes.

A MATERIAL CALCULATOR FOR THE JOB
One material calculator, eight jobs: concrete slab, tile, paint, gravel and sand are open; the subscription adds column and footing, wallpaper, bricks and blocks, baseboards, plus saved history. The tile calculator works from floor area minus openings, tile size, waste and tiles per box to the number of boxes; the paint calculator from wall run, doors, windows, coats and coverage to gallons and cans. Metric or imperial, optional +10% safety. These are indicative estimates — confirm quantities with your supplier.
