Concrete Calculator

Calculate concrete volume for slabs, footings, columns, walls, stairs, and circular shapes. Enter dimensions in feet, inches, yards, or meters — the app instantly computes cubic yards, cubic feet, and cubic meters.

Convert your calculated volume into 40 lb, 60 lb, or 80 lb bag counts based on standard yield rates. An 80 lb bag yields approximately 0.60 cu ft, a 60 lb bag yields 0.45 cu ft, and a 40 lb bag yields 0.30 cu ft[reference:0]. Get exact bag quantities for your project.

Calculate rebar quantities, spacing, and weight for slabs and footings. Determine wire mesh requirements and gravel base needs. Supports standard rebar sizes and grid configurations for proper reinforcement planning[reference:1].

Get detailed cost projections for ready-mix concrete, bagged mix, rebar, and gravel. Add a customizable waste factor (5–10%) to account for spillage and over-excavation. Adjust unit prices to match local market rates for accurate budgeting[reference:2].

Generate professional PDF estimates and material lists for clients. Include your company name, project details, and itemized cost breakdown. Export results as CSV or PDF for accounting and record-keeping[reference:3].

Work in feet, inches, fractions, yards, or meters. Convert between dimensional formats with a simple tap. All calculations, bag counts, and cost estimates update instantly[reference:4]. Fully functional offline with no internet required.
