Accurate Material and Cost Calculations

Every tool here works the same way: measurements in, quantities out, then your own prices on top. None of them invent a national average material price, because a price you did not pay is worse than no price — you know what your supplier charges you, and the cost lines only appear once you enter it. Nothing to sign up for, nothing emailed to you.

Concrete Calculator

Yardage, bags and cost for a slab, footing or pour, at your own rates, plus what actually drives the price of a concrete job beyond the ready-mix.

Paint Calculator

Paint quantities and cost for walls and ceilings separately, in gallons, with coats and coverage accounted for, plus what decides an interior or exterior painting price.

Drywall Calculator

Drywall sheets, framing, screws and insulation for a room, by sheet size and waste allowance, plus how drywall repair is priced and why it is not by the square foot.

Tile Calculator

Tiles, boxes and grout for a floor or wall, with the waste allowance that saves the second trip, plus what tile installation costs per square foot and why the rate is not one number.

Drywall Cost Calculator

Price a drywall job: board, compound, tape, screws, hanging and finishing labor, at your own rates, with the cost per square foot at the end.

Painting Cost Calculator

Price a painting job: paint, primer, preparation hours, trim, access and sundries at your own rates, interior or exterior, per square foot.

How much joint compound and tape a job takes, by finish level, converted into the boxes, pails and bags you actually buy.

Wire length and cost for a circuit run, by conductor size and material, plus what decides the price of the job: open walls, the number of openings, and what the panel can take.
