Excavation Cost Calculator
Estimate excavation costs with itemized breakdown and editable rates for local pricing.
Part of the Excavation & Earthworks calculators — see all tools in this category.
Current result
Costs use illustrative editable defaults. Replace every rate and productivity assumption with current project-specific quotes, hauling terms, disposal pricing, and crew data before using the total for planning or pricing.
Excavation length
Excavation width
Excavation depth
Predefined swell, shrink, and density values are planning defaults only. Moisture, compaction, fragmentation, and project-specific testing can materially change haul weight, truck counts, and reuse assumptions.
Planning defaults: swell 35%, shrink 15%, bank density 1,900 kg/m3, loose density 1,185 kg/m3.
Replace these with project geotechnical, supplier, measured, or contract data when available.
In unit-rate mode, the digging rate is applied to bank volume and should represent the complete excavation production allowance for the cut.
Do not show labor or equipment as additional charges unless you intentionally switch to the crew-cost method instead.

Results
Crew productivity is not used for pricing in unit-rate mode. The digging line item applies directly to bank volume instead.
Bank yd3: 130.8 at 35% swell for loose volume
Loose yd3: 176.57 using 35% swell
Loose density: 1,185 kg/m3 for payload-limited truck counts
Soil assumption basis: Predefined planning defaults
Active pricing method: Unit rate
Productivity basis: Not used for pricing; digging rate applies to 130.8 bank yd3
Swell is used for loose volume and disposal quantity. Loose density is used for payload-limited truck counts. Neither value determines OSHA soil classification.

Edited rates are saved into the shared calculator state and hidden pricing rows stay excluded from the active method total.
| Line Item | Qty | Unit | Rate | Subtotal |
|---|---|---|---|---|
| Excavation/Digging | 130.8 | yd³ | $588.60 | |
| Hauling | 13 | loads | $975.00 | |
| Disposal | 176.57 | yd³ | $2,648.55 | |
| Contingency (10%) | $421.22 | |||

How it works and assumptions
This excavation cost calculator provides a quick estimate with an itemized breakdown you can adjust to match local rates. It combines volume calculation, truckload estimation, and a selectable excavation pricing method in a single tool.
Use the editable assumptions as starting points only, then replace them with current local supplier, hauler, disposal, labor, equipment, and crew-production data before using the estimate for planning or pricing.
For concrete demolition, measure solid concrete before applying a project debris-space factor, and price disposal on the basis the receiver actually quotes. See the concrete debris, weight, and disposal guide for the two-capacity load check and quote checklist.
Self-Contained Volume Calculation
Enter the excavation dimensions (length, width, depth) and select a soil type. The calculator computes the bank volume and applies the swell factor to get the loose volume. Bank volume is the audit basis for excavation production, while loose volume supports hauling and disposal. If you want to validate the geometry or work through a more detailed shape first, use the excavation calculator.
If you have measured or contract-specific earthwork data, choose Custom/project data and enter your own swell percentage plus loose density. Swell is used for loose volume, and loose density is used for payload-limited truck counts.
Those assumptions help estimate hauling and disposal, but they do not determine OSHA soil classification. Use site observations, competent-person procedures, and project geotechnical information for classification decisions.
Pricing Methods and Cost Line Items
Each line item can move significantly based on soil behavior, site logistics, disposal rules, and crew productivity. The excavation cost factors guide explains which field conditions should push you to change the default assumptions.
In Unit rate mode, the digging rate applies to bank volume and should represent the complete excavation production allowance. Labor and equipment are not shown as separate charges in that mode.
In Crew cost mode, labor and equipment are calculated from bank-volume productivity, and the separate digging unit rate is excluded so excavation production is not charged twice.
- Unit rate mode: Excavation/digging rate per bank cubic yard
- Crew cost mode: Labor and equipment rates per hour based on bank yd3/hr productivity
- Hauling: Rate per load applied to number of truckloads
- Disposal: Rate per cubic yard applied to loose volume
Inline Rate Editing
Click any rate in the cost table to edit it with your local pricing. The totals update immediately, which makes the calculator useful for both quick estimates and detailed bidding.
The defaults are illustrative editable placeholders, not market standards. Replace every rate and productivity assumption with current project-specific quotes or crew data.
Contingency
The contingency percentage adds a buffer to the subtotal for unexpected costs. Adjust this based on how well-defined your project scope is. The excavation mistakes guide highlights the scope gaps and field assumptions that usually justify more contingency. Set to 0% for a bare-minimum estimate.
