The cost of professionally installing an electric fence usually relates to the size of the yard. It may cost up to $2,000 or more in 2011 for a basic fence that contains only one pet.
Do-it-yourself electric fence kits cost $100 to $350 in 2011, according to Cost Helper. If you need additional wires or lines to encompass more space in your yard, expect to pay up to $70 per length of wire.
If you have more than one animal outside, you need to purchase additional collars. The cost for each additional collar is $55 to $130 in 2011, depending on the manufacturer of the electric fence.
