About the Soil Bearing Capacity Calculator Online Free Tool

The Soil Bearing Capacity Calculator Online Free Tool estimates gross allowable and ultimate bearing capacity from net allowable pressure, foundation depth, width, and factor of safety. It is a planning-level geotechnical helper.

How to Use the Soil Bearing Capacity Calculator Online

1. Enter the required inputs in the fields above using the units shown on the labels.
2. Select any mode, shape, or method options so the calculation matches your scenario.
3. Run the calculation and review the result summary in the output panel.
4. Check the units, assumptions, and project requirements before using the result outside preliminary review.

Choosing Options Correctly

Inputs use kPa for bearing pressure and meters for foundation dimensions. The formula is simplified and should be checked against the project geotechnical report.

Common Use Cases

• Convert a net allowable value into a rough gross allowable value.
• Estimate an ultimate bearing capacity using a safety factor.
• Screen shallow foundation assumptions before detailed review.

Quick FAQ

Is this a geotechnical report?
No. It is a preliminary calculator and cannot replace site investigation, lab testing, or geotechnical sign-off.

Which soil parameters matter?
Unit weight, cohesion, friction angle, footing depth, footing width, and safety factor all affect bearing capacity.

Does it check settlement?
No. Bearing capacity and settlement are separate checks; both can control foundation design.

What is a common mistake?
Using assumed soil values without confirming them from site-specific investigation or a qualified report.
