iPhone
Fast, accurate concrete volume calculator. Enter your dimensions, get instant cubic yards, bags needed, and truck loads. Works offline - built for the job site.
ConcreteCalc is the fastest way to figure out how much concrete you need for any pour. Built for contractors, tradespeople, and serious DIYers who need accurate numbers on the job site — no internet required.
CALCULATE ANY SHAPE
Enter dimensions for slabs, footings, columns (sonotubes), walls, steps, or circular pads. Pick from common thicknesses or enter a custom value. Results update instantly.
VOLUME, BAGS & TRUCK LOADS
Get your total volume in cubic yards or cubic metres, the number of bags needed for each bag size, and how many ready-mix truck loads to order — all in one view.
WASTE FACTOR BUILT IN
Choose from standard waste percentages (5%, 7%, 10%, 15%) or enter a custom value. The app adds it automatically so you order the right amount the first time.
PROJECT TOTALS
Save multiple calculations to a single project. See combined volume, total truck loads, and a cost estimate for the entire job. Share a clean summary via text or email.
COST ESTIMATES
Set your local price per cubic yard (or cubic metre) and delivery fee. The app calculates estimated material cost so you can quote with confidence.
IMPERIAL & METRIC
Full support for both unit systems. Enter in feet/inches or metres/centimetres. The app defaults to your country's standard system, and you can switch anytime.
CUSTOMISABLE SETTINGS
Adjust truck capacity, bag sizes, and bag yields to match what is available in your area. Set per-bag and per-truck pricing for detailed cost breakdowns.
BUILT-IN REFERENCE GUIDE
Quick-access tables for bag yields, recommended slab thicknesses, concrete strength (PSI/MPa), sonotube sizes, waste factor guidelines, and ready-mix truck capacities.
WORKS OFFLINE
No account. No internet. No ads. Every feature works anywhere — on the job site, in a basement, or in the middle of nowhere.
