Excavation Calculator

Digging a trench, foundation, or pool requires knowing exactly how much earth you're moving — the Excavation Calculator gives you that volume and what it'll cost to remove it. Enter your pit's length, width, and depth, then select your unit of measurement (feet, meters, or inches). Add an optional cost per cubic unit and waste/extra factor to get your total volume in cubic yards, cubic feet, and cubic meters, plus total excavation cost and estimated truck loads.

Optional: Enter cost per cubic yard/meter/foot for total project cost

Frequently Asked Questions

What is excavation calculation?

Excavation calculation determines the volume of soil, rock, or other materials that need to be removed from a given area. It's essential for estimating project costs, determining truck loads needed, and planning construction timelines.

How do I convert between cubic yards, feet, and meters?

1 cubic yard equals 27 cubic feet. 1 cubic meter equals 35.31 cubic feet or 1.308 cubic yards. Our calculator automatically converts between all units for easy comparison.

Should I add extra for waste or settling?

Yes, it's recommended to add 5-15% extra to account for soil settling, measurement variations, and waste. Our calculator includes a waste factor field to help you plan accordingly.

How many truck loads will I need?

A standard dump truck holds about 10-15 cubic yards of soil. Our calculator estimates truck loads based on 12 cubic yards per load, but check with your hauling contractor for their specific truck capacity.

What are the important factors in excavation planning?

Key factors include soil type, drainage conditions, accessibility for equipment, local regulations, and disposal costs. Always check for underground utilities before digging and consider permits for larger excavations.

Can I use this calculator for different excavation shapes?

This calculator works for rectangular excavations like foundations, trenches, and building sites. For circular or irregular shapes, break the area into rectangular sections and calculate each separately.

How accurate are excavation volume calculations?

Calculations are highly accurate for rectangular areas with uniform depth. Real-world factors like sloped sides, irregular bottom, and varying soil conditions may affect actual volumes by 5-10%.

What's the typical cost range for excavation work?

Excavation costs vary widely by location, soil type, and accessibility, typically ranging from $15-50 per cubic yard. This includes digging, loading, and basic hauling. Get local quotes for accurate pricing.
