Concrete Volume Calculator

Concrete Volume Calculator helps you turn concrete project measurements into practical planning estimates before you buy bags or call a supplier.

Use it for rectangular slabs, circular slabs, walls, and footings in imperial or metric units. Enter dimensions, waste, and quantity to see concrete volume, cubic yards, cubic meters, and a waste-adjusted order quantity.

Plan DIY bagged concrete with 40, 50, 60, and 80 lb bag counts. Add your local price per bag and sales tax for a planning subtotal and estimated total. For larger jobs, use the ready-mix estimate to compare order quantity, supplier minimums, increments, fees, and tax.

You can add multiple sections, save local projects, reopen estimates, and preview or share a PDF report. The app works offline and does not require an account.
