Concrete Math Pro gives estimates to help you plan a concrete job. Please read the points below before you rely on a result.
- Quantities are estimates. Real pours vary with ground conditions, form accuracy and how the concrete is placed. Add a waste allowance and confirm the order with your supplier.
- Prices are placeholders. The prices shown when a calculator loads are examples. Enter the prices from your own store and supplier.
- Bag yields are approximate. We use the yields published by the manufacturer for standard concrete mix. Other products can differ, so check the bag.
- Thickness and reinforcement are not designed here. Typical figures on this site describe common practice. Your local building code and, where needed, an engineer decide what your project requires.
- Outside links. We link to manufacturers and other sources for reference. We do not control those sites.
The formulas and assumptions behind every result are listed on the How We Calculate page.
