Including concrete supply, wastage, and basic labour
Professional-grade calculator for patio slabs, outdoor entertaining areas, and backyard spaces
Estimate concrete volume, thickness, and total patio concrete cost in minutes. Designed for Australian homeowners, builders, and landscapers using current 2026 material rates.
Plan your outdoor patio concrete budget accurately before you pour
Enter your patio length, width, and slab thickness to calculate concrete volume in cubic metres, then apply 2026 Australian concrete rates to estimate total supply and pour cost.
See how much you may spend on concrete, pump hire, mesh reinforcement, and basic labour so you can compare quotes from local concreters with confidence.
Use typical patio slab thickness and strength options for alfresco areas, garden paths, and outdoor entertaining spaces while following good practice from AS 3600 concrete design.
Enter patio dimensions, thickness, and concrete rate below
Simple rectangular patio slab representation – measure from finished edge to edge and choose a suitable thickness for your use.
This patio concrete cost calculator multiplies your slab area by thickness to determine volume, then applies your selected 2026 concrete rate plus a per-square-metre allowance for labour and extras to estimate total project cost.
100mm Slab: Suitable for light-duty patios and garden sitting areas with no vehicle traffic.
120mm Slab: Common choice for covered alfresco areas, outdoor kitchens, and high-use patios.
150mm Slab: Recommended where vehicles may occasionally drive or park on the slab.
Note: Always confirm thickness and reinforcement with your engineer or concreter.
25 MPa: Standard domestic grade concrete used for most backyard patios.
32 MPa: Higher strength mix often used for exposed aggregate or drive-on areas.
40 MPa: Heavy-duty slabs and commercial or high-load applications.
Tip: Check finish type, exposure and drainage when selecting strength.
Concrete Rate: Supply and delivery cost per cubic metre of ready-mix concrete in 2026.
Labour & Extras: Includes placing, finishing, formwork, mesh, and basic pump allowance.
Wastage: Covers small level changes, spill, and site overbreak during excavation.
Reminder: Always compare calculator results with written quotes.
The calculator uses straightforward volume and rate formulas so you can easily check the numbers or adjust them for more complex patio shapes.
The table below shows typical example cost ranges for common patio sizes and slab thicknesses using mid-range 2026 concrete prices and standard labour allowances.
| Patio Size | Area (m²) | Thickness (mm) | Volume (m³) | Approx. Total Cost |
|---|---|---|---|---|
| Small Patio | 12 | 100 | 1.20 | $1,500 – $2,000 |
| Medium Patio | 20 | 100 | 2.00 | $2,400 – $3,200 |
| Large Alfresco | 30 | 120 | 3.60 | $4,200 – $5,400 |
| Entertaining Area | 40 | 120 | 4.80 | $5,500 – $7,000 |
| Drive-on Patio | 50 | 150 | 7.50 | $8,500 – $11,000 |
Good planning of levels, drainage, joints, and finishes helps your patio concrete slab last longer and look better with less maintenance.
