Cement, Sand & Aggregate Calculator
Estimate cement bags, sand and crush for a concrete mix.
Instant · runs in your browserAbout the Cement, Sand & Aggregate Calculator
Estimate the materials for a concrete mix: number of 50 kg cement bags, sand and crush (aggregate) in cubic feet or cubic metres. Choose a nominal mix such as 1:2:4 or 1:1.5:3, or enter your own ratio.
How it works
Wet concrete volume is multiplied by about 1.54 to get the dry volume of materials, then split according to the mix ratio.
Tip
Add 5–10% for wastage, and follow your engineer's specification for structural work.

Frequently asked questions
How accurate is this calculator?
Calculations use the standard formulas shown on the page, computed in full precision and rounded only for display. The result is only as accurate as the inputs and assumptions listed.
Can I use this for engineering design?
No. These are rough quantity estimates using the assumptions shown (wastage, densities, mix ratios). Get structural and electrical work designed and approved by a qualified engineer.
Is it free?
Yes. All tools are free to use without an account.
