What Affects Pergola Cost?
- Pergola type and roof style: The biggest driver of pergola price is the structure you choose. Mid-range supply and install rates start at $280/m² for timber open or slatted pergolas, rise to $380/m² for aluminum fixed open designs, $520/m² for solid roof options, and $650/m² for adjustable louvre roofs.
- Project size: This is an area-based calculator, so your total pergola installation cost is mainly worked out from the pergola footprint in square metres. Larger pergolas cost more overall because the per-square-metre rate is multiplied across a bigger area.
- Existing slab condition: If the slab is in good condition, the standard tier rate applies. If slab repair is needed, add $45/m² to the selected rate before multiplying by the total area, which can noticeably increase the final estimate.
- Minimum job charge: Very small jobs may still be priced at the minimum charge of $4,500 AUD. That means if the area-based calculation falls below this amount, the displayed estimate will default to the minimum instead.
Pergola Cost - Frequently Asked Questions
Pergola cost in Australia depends on the style selected and the total footprint. Midpoint supply and install rates are $280/m² for timber open or slatted, $380/m² for aluminum fixed open, $520/m² for solid roof, and $650/m² for adjustable louvre roofs. If the calculated total is very low, a minimum job charge of $4,500 AUD applies.
The pergola cost calculator uses the pergola footprint in square metres and applies the relevant mid-rate for your chosen type. It then shows an estimate range based on ±18% around that midpoint, with slab repair adding $45/m² before the area is multiplied. A minimum job charge of $4,500 AUD applies where needed.
For a typical 16 m² pergola in good slab condition, the midpoint estimate is $4,500 AUD for timber open or slatted because the calculated $4,480 falls below the minimum charge. The midpoint is about $6,080 for aluminum fixed open, $8,320 for solid roof, and $10,400 for an adjustable louvre roof. The displayed estimate range is then calculated at ±18% around each midpoint.
If slab repair is required, add $45/m² to the selected tier before calculating the total. For a 16 m² job, that takes the midpoint to about $5,200 for timber open or slatted, $6,800 for aluminum fixed open, $9,040 for solid roof, and $11,120 for adjustable louvre. These figures are before applying the displayed ±18% estimate range.
The aluminum pergola cost is higher than the timber pergola cost based on the calculator rates. Aluminum fixed open pergolas are priced at $380/m², while timber open or slatted pergolas are priced at $280/m². For a 16 m² project in good condition, that works out to about $6,080 for aluminum versus the $4,500 AUD minimum for timber.
A louvre pergola cost is the highest-priced option in this calculator because it is a premium outdoor room style. Adjustable louvre roofs are priced at $650/m², compared with $520/m² for solid roof, $380/m² for aluminum fixed open, and $280/m² for timber open or slatted. On a 16 m² footprint in good condition, the midpoint is about $10,400 AUD before the ±18% displayed range is applied.
