About this app

Estimate how much concrete your next job needs. ConcreteCalc is a concrete calculator and construction calculator for DIY projects, trades and everyday material planning. Calculate concrete volume on your Android device, even without an internet connection.

SIX PRACTICAL CALCULATORS

• Slab calculator: enter length, width and thickness for a concrete floor or slab.
• Footing calculator: calculate rectangular foundations, including multiple identical footings.
• Round footing and column calculator: use diameter, height and quantity for circular concrete work.
• Concrete bags: enter volume and the yield printed on your bag. Required bags always round up.
• Block calculator: estimate wall blocks from wall and block dimensions, with optional mortar joint width.
• Material cost: estimate ready-mix concrete or bagged material costs using your own prices.

PLAN FOR WASTE

Choose 0, 5, 10 or 15 percent reserve for quantities. See the base requirement and the total with reserve. Transfer a concrete result directly to concrete bags or material costs. Set a custom additional reserve in the cost calculator.

CLEAR RESULTS, SIMPLE INPUTS

Enter dimensions in millimeters, centimeters, meters, inches, feet or yards. Volume inputs support cubic meters, liters and cubic yards; concrete results use metric units. Both decimal commas and points are accepted. Share an estimate through the Android share sheet.

Choose English, German, Spanish, French, Italian or Portuguese, with light or dark appearance and clearly displayed results. All six calculators work offline. No account is required. A legal notice is available in the app without a connection.

OPTIONAL AD REMOVAL

The free version contains ads. ConcreteCalc Pro permanently removes banner and full-screen ads with one in-app purchase. No subscription. Ads, privacy forms and Google Play purchases may require internet access.

ConcreteCalc provides estimates. Check all results, product yields and project requirements before ordering or construction. The block calculator does not deduct doors or windows. No structural or reinforcement calculations. Material costs exclude delivery and labor.
