Concrete Calculator & Quote

Know how much concrete to order and what your materials may cost before you pour.

Concrete Calculator & Quote turns your measurements into concrete volume, ready-mix order quantities, premix bag counts and material cost estimates. Plan a patio, driveway, footing, wall or fence-post job, then keep the calculations together in a project.

CALCULATE THE SHAPE YOU NEED
Use dedicated calculators for rectangular slabs, footings and pads, rectangular columns, walls with openings, and round shapes. The round calculator covers post holes, tube piers and circular slabs. Dimension diagrams help you check the measurements you entered.

ALLOW FOR OPENINGS AND WASTE
Subtract doors, windows and custom openings from wall volume. For post holes, enter the post diameter to deduct the space occupied by the post. Set a waste allowance and a quantity for repeated elements.

PLAN YOUR CONCRETE ORDER
See the calculated volume, the volume with waste and a suggested ready-mix order quantity based on your settings. Adjust order rounding, minimum order and truck capacity where needed. Estimate premix bags using the selected bag yield.

COMPARE READY-MIX AND BAGS
Enter your own local price per volume unit and price per bag. Compare the entered material costs and include available delivery, pump or short-load fees when relevant. Results depend on your prices and selected assumptions; they are not live supplier quotes.

KEEP THE WHOLE PROJECT TOGETHER
Save named calculations, reopen previous work and combine saved items in a project. View project totals for concrete volume, bags and entered costs. Reuse recent dimensions and saved prices when planning your next pour.

SHARE A MATERIAL ESTIMATE
Copy results, prepare a supplier message or export a Material Estimate PDF. Project PDF export brings your saved items together. Standard PDFs include a watermark. Optional rewarded-ad exports offer a clean supplier PDF or high-resolution image for the current calculation when an ad is available.

METRIC OR IMPERIAL
Work in metric or imperial units and choose your currency. Check the yield printed on your concrete bag; metric bag yields must be confirmed before they are used.

CALCULATE ON SITE, EVEN OFFLINE
Core calculations and saved projects work offline. Advertising and optional rewarded-ad features require connectivity.

Built for contractors, builders and hands-on homeowners who want a practical concrete volume calculator, bag estimator and material cost comparison in one place.

IMPORTANT
This app provides material estimates, not structural engineering or certified mix-design advice. Verify dimensions, bag yields, supplier requirements and site conditions before ordering or construction. Costs exclude labor, tax, permits and other job expenses unless added manually.
