How to Use the Fence Calculator & Material Estimator
This fence calculator helps estimate the materials, quantities and approximate project cost for a new fence. It can be used for pre-made fence panels, individual vertical boards or pickets, and custom fence bays.
Enter the actual dimensions of your fence, gate openings, posts, rails, boards and other materials. The calculator then works out approximate quantities and rounds whole items up where required so you can create a practical materials-to-order list.
Fence Panel Calculator
For pre-made fence panels, enter the total fence run and the actual width of the panel you intend to use. The calculator divides the usable fence length by the panel width and rounds the result up to a whole panel.
Any gate opening you enter is deducted from the fence infill length before the panel quantity is calculated.
Fence Post Calculator
Fence posts are calculated from the number of bays or spans in each fence run. Independent runs include both end posts, while a run connected to a previous run can share the connecting corner post.
Additional posts for gates and spare posts can be entered separately.
Fence Board & Picket Calculator
For individual boards or pickets, enter the board width and the desired gap between boards. The calculator accounts for the fact that a line of boards normally contains one fewer gap than the number of boards.
Fence Rail Calculator
Enter how many horizontal rails are required per fence bay together with the finished rail length and the stock length you intend to buy.
The calculator can work out how many finished rails can be cut from each stock length before calculating the quantity to purchase.
How Fence Board Gaps Are Calculated
Board spacing can easily cause mistakes when estimating a fence manually. If a fence contains 20 boards, there are normally 19 spaces between them, not 20.
Stock Lengths and Cutting Optimisation
Timber is often purchased in lengths longer than the finished pieces used in the fence. The calculator can estimate how many finished boards, rails or bottom boards can be cut from each stock length.
The estimator uses a conservative straight-cut calculation. It does not attempt advanced cutting-stock optimisation and does not automatically allow for saw kerf, defects or unusable timber sections.
Fence Waste Allowance
Different fencing materials can require different amounts of extra material. Rather than forcing a fixed percentage, this calculator lets you enter your own wastage allowance for panels, boards, rails, bottom boards, concrete and fixings.
This makes it easier to distinguish between the exact calculated amount and the quantity you actually intend to purchase.
Fence Post Concrete Estimate
The optional concrete section estimates the volume of concrete around fence posts using either round or rectangular post-hole dimensions.
Where post dimensions and embedment are entered, the calculator deducts the approximate volume occupied by the post itself before applying the concrete waste allowance.
If you want to calculate a larger concrete quantity separately, you can also use the free Concrete Calculator .
This is a material quantity estimate only. The calculator does not determine how deep or wide a post hole should be.
Materials to Order
The Materials to Order section converts the detailed calculation into a practical purchasing list using whole units after wastage allowances and stock sizes have been applied.
- Whole fence panels or bay units
- Fence posts
- Stock boards or pickets
- Stock rail lengths
- Gravel boards or bottom boards
- Approximate concrete quantity
- Whole fixing packs
- Post caps and additional materials
Fence Cost Calculator
Material prices are optional. If entered, the calculator combines the cost of panels or timber with posts, rails, concrete, fixings and additional materials.
Delivery, equipment hire, waste disposal and labour can also be included so the result can be used as a more complete fence job estimate.
For a dedicated trade pricing calculation, you can also use the Handyman & Contractor Job Price Calculator .
Labour, Markup and Customer Price
Tradespeople and contractors can calculate labour using workers and hourly rates, workers and day rates, or a single labour amount.
If you are unsure what hourly or daily rate to use, the Hourly & Day Rate Calculator can help you work out what you need to charge.
Your chosen markup and optional VAT or sales tax are then applied to produce an estimated customer price.
After pricing the job, you can also check whether the work is actually worthwhile using the Job Profit Calculator .
Worked Fence Panel Example
A 10 m fence run with a 1 m gate leaves 9 m of fencing. With 1.8 m panels:
9 ÷ 1.8 = 5 panels.
Adding a 10% allowance gives 5.5, so the purchasing requirement becomes 6 whole panels.
Worked Fence Board Example
A 9 m fence using 100 mm boards with a 20 mm gap requires 76 finished boards.
With a 10% allowance, that becomes 84 finished boards.
If 3.6 m stock boards are cut into 1.8 m finished boards, two pieces come from each stock length.
84 ÷ 2 = 42 stock boards to purchase.
Fence Calculator FAQs
How many fence panels do I need?
Enter the total fence length, any gate opening and the actual width of the panel. The calculator divides the remaining length by the panel width and rounds up to whole panels.
Does the fence calculator round materials up?
Yes. Whole physical purchases such as panels, posts, stock timber and fixing packs are rounded up.
Can I calculate more than one fence run?
Yes. Multiple fence runs can be entered, including connected runs where a shared corner post may be used.
Does a gate reduce the number of panels or boards?
Yes. The entered gate opening width is deducted from the fence infill length before the main material requirement is calculated.
Are gate posts calculated automatically?
Gate requirements vary, so additional gate posts are entered separately rather than assumed automatically.
Can I use this as a picket fence calculator?
Yes. Select the individual boards or pickets option and enter the board width, gap, finished length and stock length.
Does the calculator work in feet and inches?
Yes. Metric and imperial measurement systems are supported.
Can I estimate fence labour costs?
Yes. Labour can be entered using hourly rates, day rates or one total amount.
Can I add VAT or sales tax?
Yes. Enter the percentage that applies to your own job or location. No tax rate is assumed automatically.
Is this a structural fence design calculator?
No. It estimates materials and costs only. It does not determine suitable post depth, spacing, fence height, footing size or wind loading.
Can I print my fence estimate?
Yes. Use the Print / Save Results as PDF button in the results section to create a clean materials and pricing summary.
Can contractors use this as a fence price calculator?
Yes. Materials, labour, other costs, markup and optional tax can all be included to estimate a final customer price.
