Build a grading and excavation planning scenario from entered earthwork volume, equipment, fill material, hauling or disposal, compaction, erosion-control material, labor, access, and permit assumptions. The calculator is not a survey, utility locate, geotechnical evaluation, excavation-protection plan, drainage design, grading design, or permit determination.

This earthwork planning result is derived from entered cubic-yard volume and equipment cost per cubic yard, fill materials, haul or disposal, compaction, erosion control, labor, permit, site access, and matching ZIP inputs; it does not estimate volume from an unverified site shape.
This page answers what the entered inputs produce under the calculator's documented assumptions. It does not answer what a local provider will charge, approve, diagnose, finance, or guarantee.
Use the result to compare like-for-like scenarios, then replace placeholders with current project records, bids, supplier quotes, authority requirements, or qualified professional review before acting.
For the grading-excavation model, the calculator multiplies earthworkVolumeCubicYards by equipmentCostPerCubicYard, adds fillMaterialAllowance, haulDisposalAllowance, compactionAllowance and erosionControlAllowance, adds laborHours times laborHourlyRate adjusted only by siteAccess, and adds permitAllowance.
Example entered grading and excavation scenario
With open access and neutral matching factors: 80 x $35 + $900 + $700 + $400 + $250 + 30 x $75 + $200 = $7,500.
The modeled planning total is $7,500 for the entered earthwork assumptions, not a surveyed quantity or safe-work determination.
Model a roof-replacement planning range from roof area, a reference asphalt installed-cost baseline, material, pitch, complexity, tear-off, and available ZIP factors. It is not a contractor quote or market price.
Model grading and leveling from area, depth, equipment hours, your crew/equipment rate, soil, access, material, haul-off, allowances, and available location factors. It is not a contractor quote.
Build an input-derived termite-treatment planning scenario from the perimeter, treatment-rate assumption, bait stations, inspection or monitoring, and any structural or fumigation allowance you enter. It is not an inspection or contractor quote.
Build a sprinkler-system installation planning scenario from measured area, zones, heads, pipe, labor, access, controller or backflow equipment, permit or design allowances, and available geographic factors.
Build a well-drilling planning scenario from entered drilling depth and rate, access, casing, pump or pressure equipment, electrical or plumbing, testing or permit allowances, and available geographic factors. It does not determine whether a site can produce safe or adequate water.
Model a blown-in insulation planning scenario from area, added R-value, your material and labor assumptions, access, air sealing, removal or cleanup, and available geographic factors. It is not an installer quote or an energy-savings prediction.

Fill in the form to get your estimate
Enter the cut, fill, or handled volume from the documented project takeoff. The calculator does not derive volume from area, slope, contours, or soil conditions.
Enter a documented equipment or earthwork-service amount using the same volume basis. It remains unindexed and is not a supplied market rate.
Enter a material-only allowance for the specified imported fill, aggregate, topsoil, or other approved material. The calculator does not select or approve fill.
Enter the quoted or budgeted hauling, tipping, and disposal amount. It remains unindexed and does not classify soil or waste or select a facility.
Enter the documented allowance for the defined compaction service, equipment, or testing coordination. It remains unindexed and does not define a specification or verify results.
Enter a material-only allowance for the project-specific erosion and sediment controls. The calculator does not design or approve controls.
Enter billable labor hours from the documented layout, site preparation, earthwork, hauling support, compaction, controls, cleanup, and closeout scope.
Enter a documented billable rate matching the labor-hours definition. The calculator does not supply a current local wage or contractor rate.
Enter only a current amount verified with the applicable authority. This field does not determine grading, excavation, stormwater, environmental, or other approval requirements.
Apply an explicit labor-only access factor. It does not assess trench hazards, protective systems, utilities, soil classification, slopes, groundwater, equipment paths, or safe work methods.
Used only for available material, labor, or permit factors. It does not provide a survey, locate utilities, supply a design, issue an approval, or establish safe excavation conditions.
