Nur Materialschätzung
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

Hole or pad dimensions
Measure the actual excavation or form dimensions. Round holes use diameter; square footings use the finished width.
Sackausbeute
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
Tiefe, width, reinforcement and soil requirements are site and code decisions. This page only estimates concrete quantity after those dimensions are known.
Common planning questions
FAQ zum Betonfundament-Rechner
Wie berechne ich Beton für runde Fundamente?
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.
Wie viele Betonsäcke brauche ich für Pfostenlöcher?
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.
Plant dieser Rechner ein Fundament?
No. It estimates concrete after you know the footing dimensions. Soil, loads, frost depth, reinforcement and local code determine the design.
Soll ich Fertigbeton oder Säcke verwenden?
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.
