How to Use This Calculator

How to Use the Fence Cost Calculator

  1. Choose metric or imperial units and your currency.
  2. Enter the total fence length and the width of one panel (standard UK panels are 1.83 m / 6 ft).
  3. Enter the price per panel, per post, and the concrete or postcrete cost per post.
  4. Add a flat figure for gravel boards, caps and other extras if needed.

How the Cost Is Worked Out

  • Panels = fence length ÷ panel width, rounded up.
  • Posts = panels + 1 (a run of fence always needs one more post than panels).
  • Total = (panels × panel price) + (posts × post price) + (posts × concrete per post) + extras.

Tips

  • Add a spare panel and post if your run includes corners or changes of direction.
  • Gravel boards lift timber panels off the ground and greatly extend their life — well worth including.
  • This is a material estimate — add labour and waste removal separately.

Common Questions

How many posts do I need for a fence?

Always one more than the number of panels — each panel sits between two posts, so a 5-panel run needs 6 posts. This calculator works that out automatically.

What is the standard fence panel width?

In the UK, fence panels are typically 1.83 m (6 ft) wide. The calculator uses this as the default, but you can enter any panel width.

Should I include concrete in the cost?

Yes — most posts are set in concrete or postcrete. Enter the cost per post (usually one or two bags of postcrete each) so it is included in the total.

Does this include labour?

No, it estimates materials only. If you are hiring a fitter, get a separate labour quote based on the fence length and ground conditions.

How can I reduce the cost of a new fence?

Choosing standard panel sizes, setting posts yourself and avoiding bespoke heights all cut costs. The calculator lets you compare options by adjusting the prices.
