Concrete Footing Cost Calculator

Concrete footings typically cost $3 to $7 per linear foot for materials. Ready-mix concrete is about $125 to $165 per cubic yard. A standard 20-ft continuous footing (2 ft wide, 12 in deep) uses about 1.63 cubic yards with 10% waste, costing roughly $200 to $270 for materials.

Footing depth depends on the frost line and load requirements. Most residential footings are 12 to 24 inches deep and must extend below the frost line (which varies by region from 0 to 72 inches). Always check local building codes for minimum depth requirements.

A general rule is that the footing width should be twice the width of the wall it supports. For a standard 8-inch foundation wall, the footing should be at least 16 inches wide. Footings for heavier loads or poor soil conditions may need to be wider.

Yes, most building codes require rebar in footings. Continuous footings typically use 2 horizontal #4 or #5 bars running the length of the footing. Pad footings use a grid of rebar in both directions. Rebar helps the footing resist cracking from soil movement and loading.

Concrete should not be poured when temperatures are below 40°F (4°C) without special precautions. In cold weather, use hot water in the mix, insulating blankets, and possibly heated enclosures. The concrete must be kept above 50°F for at least 48 hours to achieve proper strength.
