Quick answer: A DIY wireless dog fence runs $95-$350 all-in; a DIY buried-wire kit for a 1-acre yard runs about $270-$765 (typical $460 with a second dog); professionally installed invisible fences run $1,200-$2,000 for the first acre plus $200-$500 per additional acre. A wood privacy fence around that same acre runs about $20,871 at the $25/ft national typical — roughly 14 times the pro install.

National ranges, late 2025. Wood-fence comparison uses $17-$36 per linear foot installed (typical $25) around an 835-ft square 1-acre perimeter, matching our physical fence cost calculator. Pro pricing reflects dealer systems like Invisible Fence and DogWatch; independent installers often quote 10-20% less.

Perimeter = 4 × √(43,560 × acres) for a square lot; irregular shapes and doubled-back sections need more. Add 5-10% for slack and driveway crossings. Use direct-burial or UV-rated 14-18 AWG solid-core wire — cheap stranded wire fails where it's spliced.

How the Electric Dog Fence Calculator Works

Electric containment prices land in four very different buckets depending on who buries the wire and whether there is any wire at all. The calculator prices all four from the same acreage and dog count so the comparison is honest.

The formula

Wireless: base unit $95-$350, plus one collar per extra dog. DIY buried-wire: kit $150-$500 (including 500 ft of wire and one collar), plus extra 500-ft spools at ceil((perimeter − 500) ÷ 500) each, plus collars and flags. GPS: one $300-$1,500 unit per dog, subscription excluded. Pro: $1,200-$2,000 for the first acre, $200-$500 per additional acre, $100-$200 per extra collar, training included. Wire figures assume a square lot: 4 × √(43,560 × acres).

How to use it

Enter your containment acreage and dog count, then flip between systems. The wire-need figure updates with acreage — if you're splitting the yard (front only, or keeping the dog out of a garden), use the actual contained area, not the lot size. Adjust the spool and collar prices to match the hardware you're pricing.

A worked example

One acre, two dogs, DIY buried-wire: the kit is $300 with 500 ft of wire and one collar, the perimeter needs 835 ft so one extra spool adds $60, the second dog's collar adds $80, and flags run $20 — $460 typical, with a national range of $270 to $765. The same yard done professionally at 3 acres and two dogs runs $1,500 + (2 extra acres × $300) + $150 for the second collar = $2,250 typical ($1,700-$3,200), training sessions included.

Now the alternative: 835 linear feet of wood privacy fence at the $25-per-foot national typical is $20,871. Even the professional electric install at ~$1,500-$2,000 is roughly a fourteenth of that — which is the whole case for electric containment, and also its limit: it keeps dogs in, but nothing else out, and it satisfies exactly zero HOA architectural rules. Price the wood version properly with the fence cost calculator before deciding.

Frequently Asked Questions

How much does an invisible dog fence cost installed?

Professionally installed buried-wire systems (Invisible Fence, DogWatch, and local dealers) run $1,200-$2,000 for up to an acre, typically $1,500, plus $200-$500 for each additional acre and $100-$200 per extra dog collar. A 3-acre property with two dogs lands near $2,250 at typical pricing. The quote includes the wire burial, collars, and the training sessions that make the system work.

How much is a DIY wireless dog fence?

A stationary wireless system (base unit plus collar) runs $95-$350 all-in, with extra collars $60-$150 each. It covers a roughly circular area up to about half to three-quarters of an acre and takes an afternoon to set up - no burial, no wire. The trade-off is boundary wobble near strong interference and less precise edges than buried wire.

How much wire do I need for an underground dog fence?

Plan the perimeter of your containment zone: a square 1-acre area needs about 835 feet of wire, half an acre 590 feet, 2 acres 1,181 feet, 5 acres 1,867 feet, and 10 acres 2,640 feet. Most DIY kits include 500 feet, so 1 acre needs one extra 500-ft spool, 2 acres two, and 5 acres three. Add 5-10% for slack, driveway crossings, and layout tweaks.

Is an electric dog fence cheaper than a real fence?

Dramatically. A wood privacy fence around a square 1-acre lot runs about $20,871 at the $25-per-foot national typical ($17-$36/LF) - roughly 14 times a professional electric install and 45 times a DIY buried-wire kit. The physical fence buys a visible barrier that also contains kids, blocks wildlife, and satisfies HOA rules; the electric fence buys containment at a fraction of the price.

Do GPS collar fences like SpotOn and Halo cost less?

Up front they run $300-$1,500 depending on brand and bundle, with no wire or installation at all - but most carry a $5-$30 monthly subscription for the GPS services and boundary features, which is $60-$360 a year forever. For one or two dogs on a large or irregular property they're often the practical choice; for a fixed yard, buried wire wins on lifetime cost.

Does an electric fence actually work without training?

No - the training is the system. Dogs learn the boundary from flag training over roughly two weeks, and professional packages include those sessions for a reason. Skipping the flags and graduated lessons is the single most common reason DIY installs fail. Budget $0 DIY (your time, 14 days) or use the pro's included training.
