Estimate excavation and grading costs per square foot or cubic yard. Enter area, depth, and rates for total grading project cost.
Land grading is the process of leveling and reshaping the earth's surface for construction, drainage, or landscaping. Grading costs depend on the area, depth of cut/fill, soil conditions, equipment needed, and local labor rates. Understanding these factors helps you budget accurately before hiring a contractor.
This calculator estimates grading costs based on area, average depth of cut or fill, and cost rates per square foot or per cubic yard. It also includes estimates for mobilization and site access costs, which are often overlooked in DIY estimates.
Whether you're preparing a building pad, regrading a yard for drainage, or leveling a lot for landscaping, this tool gives you a realistic cost range for planning and comparing contractor bids.
This measurement supports better project estimation, enabling contractors and engineers to deliver accurate bids and avoid costly overruns during the construction process. Precise calculations are essential for meeting regulatory requirements, passing inspections, and ensuring the long-term structural integrity and safety of the completed project.
Grading costs vary widely based on scope and soil conditions. This calculator gives you a baseline estimate to check contractor bids, plan budgets, and understand the cost drivers of your grading project. Regular use of this calculation supports compliance with building codes and inspection requirements, helping projects proceed smoothly through the permitting and approval process.
Volume (yd³) = Area (sq ft) × Depth (ft) ÷ 27 Excavation Cost = Volume × $/yd³ Total = Excavation + Mobilization + Finish Grading
Result: $6,278 total grading cost
Volume: 5,000 × 1 ÷ 27 = 185.2 yd³. Excavation: 185.2 × $15 = $2,778. Finish grading: 5,000 × $0.50 = $2,500. Mobilization: $500. Total: $5,778.
Soil type: sand and loam are easy; clay is harder; rock requires specialized equipment. Depth: shallow cuts (under 6 inches) are simple; deep cuts (over 2 feet) require more equipment time. Access: tight spaces require smaller equipment at lower productivity. Disposal: excess soil hauled off-site adds $10–$25 per cubic yard.
Small areas under 1,000 sq ft with less than 6 inches of grading can be DIY with a rented skid steer. Anything larger, deeper, or near utilities should involve a professional. Improper grading near foundations can cause serious water damage.
Provide contractors with a survey or site plan showing existing and proposed grades. Specify whether topsoil, seed, or sod is included. Ask about the cost of unexpected rock or wet soil. Get the mobilization and hauling fees in writing.
Late spring and fall are the best seasons in most climates — dry enough for equipment but not too hot. Avoid grading during monsoon season or when soil is saturated. Frozen ground is expensive to grade. Schedule 2–4 weeks ahead for popular contractors.
Basic yard grading costs $0.40–$2.00 per sq ft. Rough grading for new construction: $0.50–$1.50/sq ft. Fine (finish) grading: $0.40–$0.80/sq ft. Complex grading with rock or poor access: $1.50–$3.00+ per sq ft.
Excavation and grading typically costs $5–$25 per cubic yard depending on soil type, depth, and hauling distance. Soft soil: $5–$10/yd³. Clay: $10–$20/yd³. Rocky soil: $15–$30/yd³. Hauling adds $10–$25/yd³ if off-site disposal is needed.
Mobilization is the cost to transport equipment to and from the job site. Typical range: $200–$1,000 for residential projects. Larger equipment (excavators, dozers) costs more to mobilize. Some contractors include this in the per-yard rate.
A small residential yard (5,000 sq ft) typically takes 1–2 days with a skid steer. A full lot grading (10,000+ sq ft) takes 2–5 days. Finish grading adds 1–2 days. Weather delays can extend the timeline significantly.
Most jurisdictions require a grading permit when moving more than a specified volume (often 50–100 yd³) or when the grade change exceeds 1–2 feet. Building pads and drainage modifications almost always need permits.
Rough grading establishes the general elevations and slopes using heavy equipment. Finish grading fine-tunes the surface to the final design grade, typically within ±1 inch, and prepares the surface for sod, seed, or paving.
