Earthwork — how much material is in the ground?

Work out how much material comes out of the ground — or has to go back in. Rectangular and circular excavations, sloped side walls, trench cross-sections and spoil volumes, in cubic yards, cubic feet or cubic metres.

01Excavation CalculatorBank volume in cubic yardsCubic yards of material to be dug out — including battered side walls, over-excavation and swell.02Cut and Fill CalculatorCut, fill, net and total movedCut, fill and net earthwork by the grid method — the one a site engineer uses, not area times average depth.03Trench Excavation CalculatorTrench and spoil volumeSpoil, backfill and bedding quantities for a run of trench — from the cross-section up.04Swell Factor CalculatorBank, loose and compacted volumeConvert bank, loose and compacted volumes both ways from your own swell and shrinkage, or work out your swell factor and load factor from two things you measured. No soil factor is assumed.

Cost — what will the work cost?

Turn quantities into money using rates you supply. These tools never guess a market price — you enter what you actually charge or were quoted, and the calculator handles the quantities, the unit conversions, the add-ons and the markup.

01Excavation Cost CalculatorTotal cost, at your ratesPrice an excavation from the dimensions up, using your unit rates or your hourly rates.02Trenching Cost CalculatorCost per foot and totalPrice a run of trench per linear foot, per cubic yard or by the hour — with backfill, bedding and restoration.03Land Clearing Cost CalculatorCost by acre or by lotPrice clearing a parcel by the acre, by the square foot or by the hour — plus trees, stumps and debris.04Construction Markup CalculatorPrice, markup and marginPrice from cost and markup, markup from cost and price, or the markup you need for a target margin — with the margin shown every time.05Labor Burden CalculatorBurdened hourly labor rateAdd payroll taxes, workers’ comp, insurance and benefits to a wage and get the fully burdened hourly rate — and the rate per hour actually worked.

Hauling — how many truck loads is that?

Convert a volume of material into truck loads — accounting for swell, for the difference between a truck that fills up by volume and one that fills up by weight, and for the round trips the job actually needs.

01Dirt Hauling CalculatorTruck loads and round tripsTruck loads, haul time and cost — including whether your trucks fill up by volume or by weight first.

Measurement — what is the quantity?

The everyday geometry behind every other tool on the site: cubic yards from feet and inches, areas from dimensions, and clean conversions between imperial and metric.

01Construction Slope CalculatorGrade, ratio, angle, lengthRise, run, percent grade, ratio and angle — enter any one and get the others.02Roof Pitch CalculatorPitch, angle, rafter, squaresPitch as X in 12, the angle, grade and pitch factor from a rise and run, a pitch or an angle, plus the rafter line length with overhang and the roof area in squares.03Stair CalculatorRisers, treads and stringer layoutRiser height, treads, total run, stair angle and the stringer layout from your total rise, with a cut list in feet, inches and sixteenths and in millimetres.04Square Footage CalculatorSquare feet of rooms and shapesSquare feet, square yards, square metres and acres for one shape or up to six added together, with cut-outs subtracted.05Cubic Yard CalculatorCubic yards from any shapeCubic yards from length, width and depth, from a square-foot area and a depth, or from a volume you already have in cubic feet or metres.06Board Foot CalculatorBoard feet, linear feet and costBoard feet from the thickness, width and length of each piece, for up to four lumber sizes, with the linear feet and, at your own price, the cost.
