Invisible / Electric Dog Fence Cost Calculator
Budget a buried, wireless-boundary dog fence: the boundary wire by the foot plus the transmitter, collar and install, from prices you enter.
Calculator
An invisible/electric dog fence around 500 ft is about $1,500.00 — $1,000.00 of buried wire plus $500.00 of equipment and install. Order a little extra wire for the run back to the transmitter.
An invisible or electric dog fence has no rails or pickets to count — the “fence” is a single buried boundary wire that talks to a transmitter in the garage and a receiver collar on the dog. So the cost has just three parts: the wire by the foot, the equipment (transmitter plus collar), and any install. This tool adds them up from the numbers you enter, with an optional contingency.
Because the wire follows the boundary you want to contain, the length is a perimeter, not an area. If you only know your lot size, convert it to a perimeter first with the cost to fence an acre or yard tool, then bring that footage back here. Order a little extra wire for the twist-back run to the transmitter and for any splices.
Formula
The estimate is the wire cost plus equipment and install, scaled by any contingency:
total = (boundary_ft × price_per_ft + equipment + install) × (1 + contingency_pct)
- boundary_ft — the buried-wire perimeter around the containment area, in feet.
- price_per_ft — installed (or DIY material) cost per foot of boundary wire.
- equipment — the transmitter plus one collar; add for extra dogs.
- install — professional burial and boundary training, or 0 if you do it yourself.
The buried-wire footage is a quantity you should confirm on the ground and pad by ~10% — order a little extra for the transmitter run and corners.
Worked example
A 500-foot boundary at $2/ft installed, a $300 transmitter-and-collar kit, $200 of install, no contingency:
wire = 500 ft × $2/ft = $1,000subtotal = $1,000 + $300 + $200 = $1,500total = $1,500 × 1.00 = $1,500
So about $1,500 for a professionally installed 500-foot system — roughly 500 feet of buried wire plus the equipment and setup. A self-installed kit for the same yard is often far less, since the wire and a basic transmitter kit are the only hard costs.
What an invisible fence does and does not do
It is containment, not a physical barrier. An electric fence keeps your dog in with a warning tone and a static correction; it does nothing to keep other animals, or people, out. For a pool, a road-facing yard, or a dog that will bolt through a correction, a physical fence is the safer choice — price one with the installation cost calculator or, for large rural boundaries, the farm & ranch fence calculator.
Wire length drives the cost. The boundary loop is the perimeter of the area you want to contain, so a big open acre needs a lot of wire. Use the cost to fence an acre or yard tool to turn a lot size into a perimeter, then add a margin for the run back to the transmitter and any interior exclusions (a garden bed, a flower bed) you loop out.
Wireless vs. in-ground. A true wireless system uses a circular radio signal with no buried wire — cheaper and faster, but the shape is a fixed circle and terrain can distort it. An in-ground buried-wire system costs more to install but follows any boundary shape exactly. This calculator sizes the buried-wire type; for a wireless unit, set the per-foot wire cost to 0 and enter the equipment price.
Extra collars and batteries recur. Each additional dog needs its own collar, and collar batteries are an ongoing cost this one-time estimate does not include. Before you dig any wire in, call 811 to locate utilities — a boundary trench is shallow, but irrigation, low-voltage lighting and utility lines still live in the same few inches of soil.
Reference table
| Yard size | Boundary loop (square) | +10% wire to order |
|---|---|---|
| 1/4 acre | 417 ft | 460 ft |
| 1/2 acre | 590 ft | 650 ft |
| 1 acre | 835 ft | 919 ft |
| 2 acres | 1,181 ft | 1,299 ft |
Square-lot assumption — a long, narrow yard needs a longer loop. Add wire for the twist-back run to the transmitter. Labeled planning values, not a containment guarantee.
