Calculate excavation or trench volume from length, width and depth with cubic yards, cubic meters and a sourced US cost benchmark.
Excavation and trench volume
Enter the excavation length, width and depth. The result is available in cubic meters, cubic feet or cubic yards.
Why excavation prices vary
Soil, rock, access, disposal, groundwater, equipment, shoring and safety requirements can change the final cost substantially. The displayed US range is a sourced planning benchmark, not a contractor quote.
Frequently asked questions
How do I calculate trench volume?
Multiply trench length by width by depth.
Can I convert to cubic yards?
Yes. Select cubic yards as the output unit.
Does excavation cost include hauling?
Not necessarily. The benchmark is a planning range and hauling, rock, shoring and disposal may be additional.
Why can excavation quotes vary so much?
Soil, access, depth, groundwater, equipment and disposal conditions can materially change the job.
What does Excavation & Trench Calculator calculate?
The calculator uses the measurements and values you enter and applies a defined deterministic formula. Change the inputs and the result is calculated again from those values.
Can I save this calculation to a project?
Yes. After calculating, use “Add to my project estimate” to save the result in your current Calcavera project estimate. You can repeat this with other calculators to build a multi-item project.
Can I print or save the estimate as a PDF?
Yes. Open the saved project estimate, then use the “Print / Save PDF” button. Your browser can print the estimate or save it as a PDF file.
Can I use metric and imperial units?
Yes. Where supported by the calculator, you can mix common metric and imperial input units. Calcavera converts measurements before running the calculation and shows the selected output unit.
Are the cost figures a contractor quote?
No. Cost ranges are planning estimates and appear only when an active market rate is available. Supplier pricing, labor, taxes, delivery, specifications and site conditions can change the final cost.
