Choose a Concrete Calculator
Use these tools to plan your concrete and masonry projects with confidence. Get quick material estimates in metric or imperial and avoid running short by accounting for typical waste and over-excavation.
Concrete Slab Calculator
Estimate cubic yards/meters for slabs, patios, and floors. Includes bag/truck guidance.
Open calculator →Concrete Footing Calculator
Plan concrete for strip footings, pads, and post holes based on your dimensions.
Open calculator →Concrete Bag Calculator
Convert volume to 40/60/80 lb bag counts (or your local bag sizes) for DIY pours.
Open calculator →Rebar Calculator
Estimate bar count, spacing, total length, and steel weight for slabs and footings.
Open calculator →Brick Calculator
Calculate brick quantities and mortar estimates for walls, facades, and masonry projects.
Open calculator →What These Concrete Tools Help You Calculate
- Concrete volume: cubic yards, cubic feet, or cubic meters for slabs, footings, and pads.
- Concrete bags: approximate bag counts for small pours and DIY jobs.
- Ready-mix planning: yardage totals that help you order from a concrete supplier.
- Reinforcement planning: rebar quantities, spacing layouts, and estimated steel weight.
- Masonry quantities: brick counts for walls and common projects.
Quick Tips for Better Concrete Estimates
- Measure twice and round up slightly to cover waste, spillage, and uneven sub-base.
- For larger pours, consider the logistics: access, wheelbarrow distance, or pump truck requirements.
- Use reinforcement where needed (mesh or rebar) and follow local building guidelines.
- Footings and slabs can vary by load and soil conditions — confirm specs before ordering.

Important Estimate Disclaimer
The results provided by these calculators are general estimates only and should not be considered precise engineering measurements. Actual material requirements can vary based on site conditions, local building codes, soil, reinforcement needs, climate exposure, and intended use.
These tools help you plan and budget, but they do not replace professional advice from a qualified contractor, engineer, or building inspector. Always verify dimensions and project specifications before ordering materials.
