Solo estimación de material
This calculator estimates quantity and bag cost. It does not size footings, reinforcement, frost protection, soil bearing capacity, post connections or structural loads. Follow the approved plan and local requirements.
Transparent math
How the footing estimate is calculated
- 1Find the volume of one footing
- 2Add the footings and ordering allowance
- 3Convert volume into bags
Notas de referencia
Qué confirmar antes de comprar
Hole or pad dimensions
Measure the actual excavation or form dimensions. Round holes use diameter; square footings use the finished width.
Rendimiento del saco
Bag coverage varies by product and package size. Use the yield on the current product label instead of relying on a generic bag count.
Footing design
Profundidad, width, reinforcement and soil requirements are site and code decisions. This page only estimates concrete quantity after those dimensions are known.
Common planning questions
Preguntas frecuentes sobre zapatas de hormigón
¿Cómo calculo el hormigón para zapatas redondas?
Convert the diameter and depth to the same unit, calculate π x radius squared x depth for one footing, multiply by the footing count, then add the chosen allowance.
¿Cuántos sacos de hormigón necesito para huecos de postes?
Divide the order volume by the bag yield printed on the product. Round up to full bags and confirm the yield because 50 lb and 80 lb products do not cover the same volume.
¿Esta calculadora diseña una zapata?
No. It estimates concrete after you know the footing dimensions. Soil, loads, frost depth, reinforcement and local code determine the design.
¿Debo usar hormigón preparado o sacos?
Use bags for smaller jobs when the product yield and mixing plan are practical. For larger volumes, compare a ready-mix quote, delivery minimum and placement access with the bag estimate.
