Concrete Math

How to compare ready-mix concrete quotes

Ask each supplier for the total delivered price for the same mix, volume, and address. A quote with a lower rate per cubic metre or cubic yard can cost more once minimum orders and fees are included.

Which numbers should I get from each supplier?

Worked example for a 0.66 m³ pour

Use the following sample prices in the same currency. They illustrate the comparison and are independent of local market prices.

Two quotes for the same pour
ItemSupplier ASupplier B
Rate per m³180205
Minimum order1.00 m³0.50 m³
Order increment0.25 m³0.25 m³
Billed volume1.00 m³0.75 m³
Delivery7055
Short-load fee025 below 1.00 m³
Delivered total before tax250.00233.75

Supplier B costs 16.25 less. Its material charge is 0.75 × 205 = 153.75. Adding delivery and the short-load fee brings the total to 233.75.

When should I compare bags too?

For small jobs, multiply your whole-bag count by the local price per bag. Include transport, mixing equipment, and labour when making a buying decision. Use the metric concrete guide to convert a pour volume into a bag count from the label yield.
