Soil Excavation Cost Calculator
Estimate the amount of soil to remove and the cost from the pit size and the rate charged per cubic metre.

Formula
How the calculation works
The calculator multiplies the length, width and depth of the pit to get the volume in cubic metres.
It then multiplies that volume by the rate charged per cubic metre to give the total cost.
The depth should be the firm soil to be removed, not counting the sand or gravel fill added back afterwards.
Common mistakes
- Measuring only the surface and forgetting the depth, since the cost depends on the volume and not the area of the pit.
- Ignoring that loose soil takes up more space, which increases the truck trips needed to haul it away.
When to use it
- Builders use it to budget excavation for foundations, septic tanks or pits before hiring labour.
- Homeowners use it to compare the cost of digging by hand with renting a small excavator.
Worked example
A pit 3 metres long, 2 metres wide and 1.5 metres deep holds 9 cubic metres, and at 450 taka per cubic metre the cost is 4050 taka.
Common questions
Does the rate include removing the soil?
It depends on the contractor, so it is worth clarifying whether the rate per cubic metre covers only digging or also loading and carrying the soil off the site.
