Colorbond fence calculator: cost for common lengths
Colorbond fencing is priced per metre installed. These are the calculator's estimates on our national fencing figures, with the half share you would pay if a neighbour splits the cost.
| Fence | Colorbond 1.8 m | Your half share | Colorbond 2.1 m |
|---|---|---|---|
| Side fence, 15 m | $1,200 to $2,850 | $600 to $1,425 | $1,800 to $3,750 |
| Back fence, 18 m | $1,440 to $3,420 | $720 to $1,710 | $2,160 to $4,500 |
| Full boundary, 40 m | $3,200 to $7,600 | $1,600 to $3,800 | $4,800 to $10,000 |
Gates are extra: a single gate is $250 to $650 and a double or driveway gate $800 to $2,500. Removing the old fence adds $15 to $50 per metre.
How the calculation works
Panels and posts. The number of panels (or bays) is the fence length divided by the post spacing, rounded up, and a straight run needs one more post than it has panels. The example the calculator opens with is 30 m at 2.4 m spacing: 13 panels and 14 posts. Use the panel width of the product you are buying as the spacing, and add posts for corners and gates.
Cost is the length multiplied by the per-metre row for the fence type you pick. Gates and removal of the old fence each add their own row from the same guide.

Frequently asked questions
How do I work out how many fence panels and posts I need?
Divide the fence length by the post spacing and round up to get the panels, then add one for the posts on a straight run. 30 m at 2.4 m spacing is 13 panels and 14 posts. Add posts for corners and gates.
How much does a fence cost per metre?
Our national fencing guide puts a Colorbond fence at $80 to $190 per metre, with $130 typical. Timber paling is $80 to $190 and picket $60 to $250 per metre. Choose your city in the calculator to use that city's figures.
How much does pool fencing cost per metre?
Our national guide lists glass pool fencing at $300 to $800 per metre and aluminium pool fencing at $100 to $350 per metre.
How much do gates and removing the old fence add?
Our national guide lists a single gate at $250 to $650 installed, a double or driveway gate at $800 to $2,500 installed, and old fence removal at $15 to $50 per metre.
Can it show my half of a shared fence?
Yes. Tick the half share box and the result shows half of the estimate. How the cost of a boundary fence is actually shared is set by the dividing fences law in your state or territory, so check that before you agree a split with your neighbour.
How much does a Colorbond fence cost?
Our national fencing guide puts a standard Colorbond fence at $80 to $190 per metre, typically $130. An 18 m back fence comes to $1,440 to $3,420, so your half of a shared fence would be about half that.
