Estimate slabs, walls, footings, columns, circular pads, post holes and area-based pours—with US/metric units, bag counts, saved history and shareable results.
Plan concrete pours with confidence. Concrete Calculator turns project dimensions into concrete volume and whole-bag estimates for slabs, walls, footings, columns, circular pads, post holes, and known-area pours.
BUILT FOR REAL POUR TYPES
• Concrete slabs for floors, patios, and driveways
• Poured walls with deductions for multiple rectangular openings
• Strip and isolated footings
• Solid round columns
• Circular slabs, pads, and bases
• Round or square post holes with post-displacement deductions
• Area-based slabs for projects where the surface area is already known
VOLUME AND BAG ESTIMATES
See the total concrete required in cubic yards and cubic feet, or cubic meters and liters. Add an adjustable extra percentage for waste, choose a common bag size or enter a custom size, then use the package yield to calculate the number of whole bags to buy.
US AND METRIC UNITS
Work in feet, inches, meters, centimeters, and millimeters. Switch unit systems or mix supported dimension units while preserving the physical measurements of your estimate.
FREE SLAB CALCULATOR + OPTIONAL PRO
The Concrete Slab calculator is free to use. Optional Pro access unlocks six additional calculators: Wall, Footing, Post Hole, Column, Circular Slab, and Area-Based Slab. Choose from available subscription or lifetime purchase options in the app. Purchases are managed by the App Store and can be restored.
SAVE, EDIT, AND SHARE
Save estimates to on-device history, search and sort saved work, rename projects, reopen calculations for changes, and share a clean full-results image with your crew or customer.
CLEAR CALCULATION DETAILS
Review the calculated volume, extra amount, total required volume, package yield, and rounded bag count. Built-in formula references explain how each supported pour type is calculated.
No sign-up is required. After initial setup, calculations and saved history are available on device; purchases and restoration require an internet connection.
Always verify site measurements, product yield, local building requirements, and material needs before purchasing or pouring concrete.
