Fencing cost calculator for India: work out posts, rolls and your price

The estimator asks one question at a time and builds your fence on screen as you answer.

1. Tell us about the site: what you are protecting, what the fence must keep out, anything you want on top, and how big it is, as a boundary length or an area in acres, guntha, hectares or square feet.
2. Choose how long it must last, say where the site is, and who installs it. Your fence builds up on screen as you answer: grade, technology, height, toppings and quantities.
3. Get your price on WhatsApp: leave your name and mobile number, and send the message with your reference code from your own phone. Our team replies with the price.

• What it keeps out decides the technology. Animals: the Q-Knot fixed knot fence, with the graduated grid, tightest at the bottom where boar and small animals push. For nilgai and cattle, SIMO Securon suggests Zeta Nova or Alpha at 6 ft; Pi suits wild boar and smaller animals. People: the ZS-Knot (Anti Climb) 4 x 2 inch grid, with RTHT barbed wire or concertina coil on top. Which height suits which animals: see how to protect crops from nilgai and wild boar and the cattle fencing guide.
• How long it must last decides the grade, by rated life: Pi for 10 years; Zeta Nova for 20 years; Alpha for 35 years or more. ZS-Knot is made in Alpha and Zeta Nova only.
• The site sets the starting design, from SIMO Securon’s suggested designs by site type: farm, plot and farmhouse, solar park or factory and data centre. You can change the toppings.

• Boundary length: as you give it, or from the area and the shape of the plot. A square plot of area A has a boundary of 4 times the square root of A; a rectangle three times as long as it is wide has a longer one.
• Posts (poles): an intermediate post every 5 metres, and a strain post at every corner where the fence is pulled tight, at every 10th post along a straight run, and on each side of every gate. An open run has a strain post at each end.
• Rolls: the boundary length divided by the roll length, rounded up, for the roll lengths made in your grade and height.
• Toppings: RTHT barbed wire per strand, and concertina coil, along the whole boundary.
• Against chain link: the same boundary with conventional galvanised chain link, counted at a post every 2.5 metres (chain link posts stand 2.5 to 3 metres apart). Why the gap differs: knotted fence vs chain link.

A square one-acre plot is about 64 metres a side and about 255 metres around. At a post every 5 metres that is about 51 posts, against about 102 for conventional galvanised chain link at a post every 2.5 metres. The calculator counts each side on its own, rounds it up, and adds a strain post at each corner and every 10th post, so for a square acre with four corners and no gate it shows 52 posts, against 104 for chain link.

For 5 acres, square, with four corners and one gate, the calculator counts 118 posts in all, against 230 for conventional galvanised chain link. The full method, per acre, per metre, per sq ft and per km, and how to compare quotes, is in fencing cost in India.

ISO 9223 grades how corrosive the air is, from C1 (very low) to C5 and CX (very high and extreme). C1 to C3 typically covers inland rural areas, towns and cities, and light industry. Sites within 20 km of the coast, and chemically aggressive sites, are usually C4 or above and need a site-specific recommendation. Tick the box on the screen that asks where the site is, and the estimator flags it for the team, who will advise.
