A concrete delivery calculator combines two separate planning jobs: working out how much concrete is required and estimating how that quantity may translate into ready-mix deliveries and supplier charges. The first part is geometry. The second part depends on the commercial details of the quote, such as the truck or load capacity, concrete rate, delivery fee, small-load charge and other site-specific services.
The calculator on this page deliberately keeps those inputs editable. It does not assume that every supplier uses the same truck size or the same price per cubic metre. Enter the figures from the quote you are comparing, then use the calculated result as a planning aid before you confirm the order.
For a rectangular slab, pad or similar project, multiply length by width by depth. All three measurements must use compatible units. When thickness is entered in millimetres, divide it by 1000 to convert the depth to metres before multiplying.
Volume (m³) = Length (m) × Width (m) × Depth (m)For example, a 6 m × 4 m slab at 100 mm thick has a base volume of 2.40 m³ because 100 mm equals 0.10 m and 6 × 4 × 0.10 = 2.40. The calculator also includes strip footing and round pad modes, plus a direct known-volume mode for users who already have a take-off.
Real formwork and excavation are not always identical to a perfect drawing. A hand-dug trench can widen, a prepared base can contain low spots, and small changes in edge thickness can affect the final volume. That is why many planning estimates include a modest allowance rather than ordering the exact geometric volume with no buffer.
There is no universal percentage that is correct for every job. A well-formed slab on a controlled base can be easier to estimate than an irregular excavation. Use the waste field to reflect the actual quality of your measurements and site preparation.
Adjusted Volume = Base Volume × (1 + Waste % ÷ 100)Some suppliers accept orders in particular increments. The calculator lets you leave the calculated quantity unrounded or round it upward to 0.01 m³, 0.05 m³ or 0.10 m³. This is a mathematical convenience only. Always ask the supplier how concrete is actually sold and invoiced in your area.
The truck-load estimate is based entirely on the truck capacity you enter. If the supplier tells you that the usable load for your order is a particular number of cubic metres, enter that figure. The calculator divides the order volume by the capacity and rounds up to the next whole load, because a partial final load still represents a delivery.
Estimated Loads = Order Volume ÷ Entered Truck Capacity, Rounded UpConcrete prices can differ by region, mix specification, strength, additives, order size and market conditions. A useful delivery calculator should therefore let you enter the actual A$/m³ figure from a supplier instead of relying on a generic price. The same applies to delivery charges.
The page separates three cost inputs: the concrete rate per cubic metre, the delivery fee per estimated load and an optional short-load or service fee. This makes it easier to compare two quotes that structure charges differently.
| Quote Item | Calculator Input | How It Is Used | Why It Matters |
|---|---|---|---|
| Concrete Supply | A$/m³ | Order Volume × Rate | Usually The Largest Material Component |
| Truck / Load Capacity | m³ Per Load | Order Volume ÷ Capacity | Used To Estimate Delivery Loads |
| Delivery Fee | A$ Per Load | Loads × Fee | Transport Can Change The Delivered Total |
| Short-Load / Service Fee | A$ Total | Added Directly | Useful For Supplier-Specific Extra Charges |
Total = (Order Volume × Concrete Rate) + (Estimated Loads × Delivery Fee) + Other Entered FeesThis is intentionally a simple budgeting formula. It does not automatically add pumps, labour, reinforcement, formwork, excavation, testing, waiting time or placement equipment because those costs depend on the project and may be supplied by different contractors.
Bagged concrete can be practical for small repairs, post holes and compact jobs where truck access is difficult. As the required volume increases, the number of bags and mixing cycles can become substantial. If you are deciding between the two approaches, use the Concrete Bag Coverage Calculator to estimate bags and compare that result with this ready-mix delivery estimate.
For projects where you still need to calculate the underlying cubic metres, the Concrete Calculator Australia can help with slabs, pads, footings and holes. You can then bring the calculated volume back to the known-volume mode on this page.
A correct volume estimate does not guarantee a smooth pour. The delivery vehicle needs a safe route and an appropriate discharge position. Consider driveway strength, overhead clearances, turning space, soft ground, gates, slopes, nearby traffic and the distance from the truck to the placement point. If the truck cannot safely reach the pour, you may need a pump or another placement method.
Do not assume a loaded concrete truck can drive onto any residential surface. Discuss access with the supplier before delivery and keep people clear of vehicle movements. For workplace safety guidance, refer to Safe Work Australia and the safety requirements applicable to your site.
Concrete delivery is time-sensitive. The project team should be ready before the truck arrives, with formwork, reinforcement, tools, access and labour organised. Multiple loads also need sequencing so the placement team can keep up. A delay on site can lead to waiting charges or create placement problems, while deliveries that arrive too far apart can affect continuity.
The calculator estimates how many loads may be required from the capacity you enter, but it does not create a dispatch schedule. Confirm the actual load sequence, interval and discharge expectations with the ready-mix supplier.
Small ready-mix orders can be priced differently from full loads. A supplier may use a minimum order, short-load surcharge, cartage fee or other service charge. The wording and calculation method can vary. Use the optional service-fee field for a known fixed extra charge from your quote rather than trying to guess one.
A pump can be needed when the truck cannot discharge close enough to the work or when the pour layout makes direct chute placement impractical. Pump hire, line setup, minimum hours, travel and labour can materially change the project budget. These are deliberately excluded from the basic delivery total unless you manually include a quoted amount in your broader project budget.
Suppose a slab requires 4.00 m³ before allowance. Adding 10% gives 4.40 m³. If the supplier confirms a 6.00 m³ load capacity, the mathematical estimate is one load. If the entered concrete rate is A$400/m³ and delivery is A$150 per load, the simple total before other fees would be A$1,910. This is only an example to demonstrate the calculation, not a current market price.
| Example Project | Base Volume | Waste | Order Volume | Entered Capacity | Estimated Loads |
|---|---|---|---|---|---|
| Small Patio Example | 1.50 m³ | 10% | 1.65 m³ | 6.0 m³ | 1 |
| Driveway Section Example | 5.40 m³ | 8% | 5.83 m³ | 6.0 m³ | 1 |
| Larger Slab Example | 8.00 m³ | 10% | 8.80 m³ | 6.0 m³ | 2 |
| Footing Example | 3.20 m³ | 5% | 3.36 m³ | 5.0 m³ | 1 |
The calculator estimates quantity, loads and entered costs. It does not choose structural dimensions, reinforcement, concrete strength, slump, exposure classification, joints, curing, pump requirements or site safety procedures. Those requirements should come from the project documents, engineer, builder, supplier or other qualified professional as appropriate.
