About Concrete Calculator: Slab
Concrete Calculator opens with a result already on screen — a standard slab, its volume and the bags you need. Change the numbers and it updates as you type. Nothing to set up first.
FOUR SHAPES
• Slab • Footing • Round column • Steps
Each shape opens with sensible dimensions already filled in, so you are never staring at an empty form.
WHAT YOU ACTUALLY NEED TO BUY
• Volume in m³, ft³ and yd³
• Bag count for 40, 60 and 80 lb and 20, 25 and 40 kg bags
• Mix ratios (1:2:3, 1:2:4) broken into cement, sand and gravel
• Total weight
• Waste allowance at 5% or 10%
METRIC AND IMPERIAL
Switch units at any time. The result converts with it — no re-entering anything.
KEEP YOUR POURS
Name and save a job, then pull it back later. The app remembers what you last worked on.
WORKS OFFLINE. No account, no network needed for any calculation.
Remove ads with a one-time purchase, or unlock unlimited saved projects and the full quote export.
Pro: no ads, unlimited use, all features unlocked. One-time purchase.
