FootingCalc: plain facts

FootingCalc is a free collection of concrete footing calculators — footing volume (cubic yards and bags), linear feet of footing, footing cost, support pad, and deck footing calculators — built by the team behind FootingTakeoff.

Key formulas used: footing volume ft³ = (width in ÷ 12) × (depth in ÷ 12) × length ft; cubic yards = ft³ ÷ 27; 80 lb bag yield ≈ 0.60 ft³; tube volume = π × (diameter ÷ 24)² × (depth ÷ 12).

FootingCalc is built by the team behind FootingTakeoff, an AI takeoff tool that reads entire footing plans and returns total linear feet, pad counts, and contractor invoices automatically.
