Excavation Cost Calculator: Free Online Digging Cost Estimator
Use our free excavation cost calculator to estimate the cost of digging, trenching, and site excavation for any construction or landscaping project. Designed for general contractors, landscapers, and property developers, this tool calculates excavation costs from volume, soil type, and local rates. Enter your project dimensions to get instant cost estimates for equipment, labor, and hauling.
How to use this calculator.
- Enter your excavation volume. Input the total cubic yards of material to be excavated. If you don't know the volume, use our earthwork calculator first.
- Select the soil type. Choose from topsoil, clay, sandy loam, gravel, or rock. Harder materials require more expensive equipment and take longer.
- Set equipment type. Choose the equipment likely needed: mini excavator, skid steer, backhoe, or full-size excavator based on your project scale.
- Include hauling distance. Enter the distance to the dump site or specify if material stays on site, which eliminates hauling costs.
- Review the breakdown. Results show equipment, labor, hauling, and disposal costs as separate line items.
How do you calculate excavation and earthwork costs?
Excavation costs combine equipment rental (or owned equipment operating cost), labor, hauling, and disposal fees based on volume and conditions.
Total Cost = Volume (cu yd) × (Equipment Rate + Labor Rate + Hauling Rate) + Fixed Costs
Where:
- Equipment rate: $3–$10 per cubic yard depending on soil type and machine size. Rock excavation can reach $20–$50 per cubic yard.
- Labor rate: $1–$3 per cubic yard for machine excavation. Hand digging costs $40–$80 per cubic yard.
- Hauling rate: $0.25–$1.00 per cubic yard per mile one-way, plus dump fees of $20–$60 per truckload.
- Fixed costs: Mobilization ($150–$500), permits ($50–$500), locates (free via 811).
Example calculation.
Let's calculate the cost to excavate for a residential foundation.
Scenario: Excavating 80 cubic yards of clay soil for a house foundation, with material hauled 10 miles to a disposal site.
- Equipment (mid-size excavator): 80 cu yd × $5/cu yd = $400
- Operator labor (8 hours at $75/hr): $600
- Hauling (80 cu yd, 10 miles): 80 cu yd × 1.4 tons/cu yd = 112 tons. At 20 tons per truckload, that is 6 truckloads. 6 × $125 = $750
- Disposal fees: 6 loads × $40 = $240
- Mobilization and permits: $300 + $150 = $450
- Total estimated cost: $400 + $600 + $750 + $240 + $450 = $2,440
Result: Foundation excavation for this home is estimated at approximately $2,400–$2,800 including a 15% contingency.
Tips from the field.
- Call 811 before any excavation. Utility locates are free and legally required in all 50 states. Hitting a utility line costs $1,000–$50,000 in repairs and can cause injury or death.
- Keep excavated material on site when possible. Hauling and disposal often represents 30–50% of total excavation costs. Stockpile topsoil for later landscaping use.
- Don't underestimate rock. If your geotechnical report mentions rock within the excavation depth, add 50–100% to your budget. Rock requires hydraulic hammers, blasting, or rippers.
- Compact fill in lifts. If backfilling the same hole later, place and compact fill in 6–12 inch layers. Full-depth dumping will settle and create low spots.
- Get multiple quotes. Excavation pricing varies dramatically by contractor workload, equipment availability, and competition. Always get at least three written quotes.

Frequently asked questions.
How much does excavation cost per cubic yard?
Excavation costs typically range from $5 to $15 per cubic yard for simple digging, with an average of $8 per cubic yard. Factors affecting cost include soil type (rock costs more), access difficulty, equipment needed, and local labor rates. Use our calculator above for a project-specific estimate.
How is trucking cost calculated for excavation?
Trucking costs are calculated based on the volume of excavated material (in cubic yards), multiplied by a swell factor of 1.35 (excavated soil expands), then multiplied by the hauling distance and per-mile trucking rate, divided by the truck capacity (typically 16 cubic yards per load). For example: (50 cu yd x 1.35) x (10 miles x $5/mile) / 16 = $105.47.
What factors affect excavation costs?
Key factors include: soil type (sandy soil is easier than clay or rock), depth of excavation, site accessibility, utility location requirements, disposal fees, permits, groundwater levels, and whether shoring or slope stabilization is needed. Rocky soil can double or triple excavation costs compared to sandy soil.
How much does basement excavation cost?
Basement excavation typically costs $10,000 to $30,000 for a standard 1,500 sq ft basement at 8 ft depth, depending on soil conditions, site access, and local rates. This works out to approximately $6 to $12 per cubic yard of excavated material. Use our calculator with your exact dimensions for a detailed estimate.
How much does excavation cost?
Excavation costs $50-$200 per cubic yard depending on soil type, depth, and access. Simple topsoil removal: $50-$75/yd³. Foundation excavation: $100-$150/yd³. Rocky soil or tight access doubles costs. Most residential projects cost $1,500-$5,000 total.
Do I need a permit for excavation?
Most jurisdictions require permits for excavations deeper than 3–4 feet or within public right-of-way. Foundation excavations always require building permits. Check with your local building department before digging.
How long does excavation take?
A typical residential foundation excavation (50–100 cubic yards) takes 1–2 days with a mid-size excavator. Large commercial excavations may take weeks. Weather, soil conditions, and rock can significantly extend timelines.
What is the difference between cut and fill excavation?
Cut excavation removes material to lower the grade. Fill excavation involves placing and compacting material to raise the grade. A balanced site minimizes both. Selective excavation may be required for contaminated or unsuitable soils.
How do I find a reliable excavation contractor?
Look for licensed, bonded, and insured contractors with specific excavation experience. Ask for references from recent similar projects. Verify their equipment is appropriate for your job size. A contractor showing up with a mini excavator for a 500-yard job is a red flag.
