Calculator.
Work out how much concrete you need in cubic metres — plus the total cost with delivery and VAT.
Concrete Volume Calculator
Prices shown are for C35 mix. Other grades available at different rates — see full concrete prices. With volumetric concrete you pay only for what you actually use — this is just an estimate.
How the calculator works
Concrete is sold by the cubic metre (m³). To calculate volume, our calculator uses the simple formula:
Length × Width × Depth = m³
For circular columns it uses π × radius² × height.
Pricing is calculated using our current C35 rate of £120 per m³ ex-VAT, plus a fixed £60 delivery charge, plus 20% VAT on the total. Other grades are available at different rates — see full prices.
