Concrete Footing Cost Calculator

Updated 2026-05-16

Estimate concrete footing material cost from dimensions and price per cubic yard.

Quick estimate: 521 USD for 40 ft by 2 ft slab, 12 in thick, 160 dollars per cubic yard, and 10% waste.

What affects concrete footing cost?

Footing cost depends on trench length, width, depth, concrete price, waste, excavation, forms, rebar, access, inspection requirements, and whether the footing is continuous or stepped.

Footing material cost vs installed footing price

This page estimates concrete material. A real footing budget can include excavation, forming, reinforcement, inspection, pumping, labor, and soil or site requirements.

Stepped footings need separate measurements

When footing dimensions change, calculate each run separately. Steps, pads, corners, and thickened areas can add volume beyond a simple straight run.

Before you calculate

  • Measure the formed dimensions, not just the finished visible surface.
  • Break complex foundations into separate rectangular sections.
  • Use thickness in inches and keep waste visible for excavation and form variation.

Common mistakes

  • Missing thickened edges, grade beams, steps, or separate footing runs.
  • Using plan dimensions without checking actual forms.
  • Treating a material calculator as structural design.

Formula

cost = (length * width * (thickness / 12) / 27) * (1 + wastePercent / 100) * pricePerCubicYard

Assumptions

  • This estimates material cost only.
  • Labor, forms, reinforcement, and engineering are not included.
  • Local prices vary.

Example

Estimated concrete cost: 521 USD

How to estimate concrete pad cost

  1. Measure the concrete pad cost area using slab length and width in feet, then enter the planned concrete thickness in inches.
  2. Convert the slab volume to cubic yards so the price per cubic yard input matches ready-mix pricing.
  3. Add waste for form variation, subgrade unevenness, ordering minimums, and final top-off.
  4. Multiply cubic yards with waste by the editable price per cubic yard to estimate material cost.
  5. Treat the result as material cost unless labor, delivery, forms, reinforcement, base prep, finishing, and permits are included separately.

Before you buy materials

  • Confirm dimensions, reinforcement, and inspection requirements before ordering concrete.
  • Use the estimate as a quantity planning number for supplier conversations.

FAQ

How do I estimate concrete footing cost?

Calculate footing cubic yards, add waste, then multiply by your concrete price per cubic yard.

Does this include rebar?

No. Rebar, chairs, ties, laps, inspection, and labor are separate from concrete material cost.

Can this size a footing?

No. It estimates material cost from dimensions you enter; it does not design footing size, bearing, frost depth, or reinforcement.

Should stepped footings be calculated separately?

Yes. Break stepped or changing footings into separate runs with their own dimensions.
