Frequently asked questions
Is Concrete Calculator a final answer?
No. It is an estimate based on the inputs and formula shown on the page; verify it against your contract, rules, and circumstances.
Why is the result different from another source?
Inputs, rounding, fees, rates, dates, and formula conventions can all produce different results.
Can I use this for a medical, financial, or legal decision?
Do not rely on it alone. Consult a qualified professional for health, lending, tax, investment, or legal decisions.

Concrete-volume method
Volume = length × width × depth, after converting depth from cm to m. The tool converts m³ to yd³ and divides by 0.018 m³ per 40 kg ready-mix bag, rounding bag count up.
Example check: a 5 m × 4 m slab at 10 cm depth is 2 m³; at the page's bag assumption, that is ceil(2 ÷ 0.018) = 112 bags.
