Free Concrete Materials Calculator – Estimate Quantities

Cement-Sand-Aggregate Ratio Calculator for Construction

Builder using cement-sand calculator on tablet — Precisely calculate materials for your next concrete project

Planning your next concrete project? Our free Concrete Mix Calculator takes the guesswork out of estimating materials, ensuring you get the exact quantities of cement, sand, and aggregate needed for any mix ratio—whether standard (1:2:4, 1:3:6) or custom. Perfect for slabs, footings, columns, and DIY projects, this tool helps builders, contractors, and homeowners optimize material usage and reduce waste.

Simply enter your wet concrete volume (in cubic meters, feet, or yards), select your preferred mix ratio, and choose output units (kg, lbs, or cement bags). The calculator automatically factors in the 1.54 dry volume multiplier (accounting for compaction and voids) to deliver precise results. Instantly view:
✔ Cement required (in bags or weight)
✔ Sand volume
✔ Aggregate quantity
✔ Total dry volume

Key features include:
✅ Interactive pie chart visualizing material distribution
✅ Step-by-step breakdown of calculations for transparency
✅ Multilingual support (10 languages, including RTL for Arabic/Urdu)
✅ Printable & shareable results for contractors and clients
✅ Mobile-friendly design for on-site use

Whether you’re a professional builder ensuring accurate estimates or a DIY enthusiast planning a patio, this tool saves time and money by eliminating manual errors. It follows industry-standard formulas (ASTM/IS codes) for reliability, helping you avoid over-ordering or last-minute shortages.

For slab calculations, first determine volume (Length × Width × Height), then input here to get instant material quantities. Need stronger concrete? Adjust ratios (e.g., 1:1.5:3 for higher strength) and compare results.
