A ground fault circuit interrupter (GFCI) electrical outlet is a good investment because it protects against electric shocks in wet areas. Expect to pay between $130 and $300 to get one installed, with an average price of about $210.

A GFCI outlet is a type of electrical outlet that works by sensing that a person's body is being shocked by the outlet, and then shutting off the power. They are particularly important in areas that may come in contact with water, which is why they’re most common in kitchens and bathrooms. Learn what replacing GFCI outlets will cost you, and what factors into those costs.

How Much Does It Cost to Install a GFCI Outlet per Unit?

A GFCI outlet costs between $7 and $25 each. So as you can see, materials make up a very small proportion of the cost of this project—it's mostly labor. When you’re dealing with electrical work, proper installation is crucial.

How Many GFCI Outlets Can I Get on My Budget?

You have an idea in your head of how much you want to spend, but how much will that get you? This range should give you an idea of how much replacing GFCI outlets will cost you, including labor. 

Average costs for installing GFCI outlets with the outlet itself ranging from $7 to $25

$50

If you have experience as an electrician, the cost to install an outlet could be $50 or less, with the only expenses being the outlet itself and some extra materials like wiring.

$150

This is the low end of what you'd expect to pay to have a professional install a new outlet. A pro may take up to two hours to install a new outlet, so if you get one at the low end of the spectrum ($40 to $50 per hour), you may be able to get a GFCI outlet installed at this price (labor plus the cost of the outlet itself).

$200

This is the average price to get a GFCI outlet installed. Generally, you're paying this much if you're getting an average rate from an electrician and you're getting a couple of outlets installed.

$300

Your price will end up on the higher end if you're getting multiple outlets installed, although the price per outlet will drop steeply after the first. In fact, a skilled electrician can install several outlets in an hour.

$500+

At this price point, you should be able to get a skilled electrician to install GFCI outlets throughout your house.

How Much Does It Cost to Install a GFCI Outlet Yourself?

Because most of the cost of this project is labor, you can save a few hundred bucks by doing the job yourself. However, because of the safety issues involved, it's a good idea to go with an electrician instead.

If you do have experience doing this type of work, here's what you'd expect to pay in terms of materials:

  • GFCI outlet: $7–$25 each

  • Electrical tape: $2–$5

  • Voltage tester pen: $20–$30

  • Wire stripper: $10–$15

  • Screwdriver: $10–$20

  • Flashlight: $20–$25

What Factors Influence the Cost to Install GFCI Outlets?

The factors that affect the price of installing GFCI outlets break down into three main categories: the number of outlets you want installed, whether you hire a professional or do it yourself, and whether you'll need to purchase the tools for the job.

Number of Outlets

The number of outlets you need is the big driver, as obviously you'll need to buy each outlet and then add extra time for the installation of those additional outlets. Fortunately, the more outlets you're installing, the less time it will take per outlet. But you can still expect a big total price difference between installing one outlet versus installing 12.

Hire a Pro or DIY

You can save a lot of money by doing the job yourself since parts are inexpensive. However, as with any electrical work, we highly advise that you not do this work yourself if you don't have the experience. When you are dealing with electrical work, you risk your safety if you don't know what you're doing.

A professional electrician charges an average of $55 per hour, but labor rates can range from $40 to $100 per hour. Depending on your pro, they may charge by the hour or per outlet.

Tools Needed

If you're starting from scratch and don't have the tools for the job, you may need to spend $100 or so on wire strippers, a voltage tester pen, and so on. However, once again, if you don't have the basic tools for the job, it's probably not something you should be doing on your own. Contact an electrician in your area and get a quote.

FAQs About Installing a GFCI Outlet

What special GFCI requirements are there for each room?

You will need to meet the following code requirements for installing a GFCI outlet in the following rooms:

  • Bathrooms: The outlet needs a 20-amp circuit, and all outlets need GFCI protection.

  • Kitchen: The outlet needs at least two 20-amp small appliance circuits for the countertop, and outlets that are within 6 feet of a sink must be GFCI-protected.

  • Laundry room: The outlet needs a 30-amp, 240-volt circuit with four conductors, and all receptacles need GFCI protection.

  • Garage: You will need one outlet for each car space, and all outlets will need GFCI protection.

Does every outlet in a kitchen need to be GFCI?

Not necessarily; just the outlets that serve countertop surfaces. You should install GFCI outlets wherever there could be a lot of wet areas, so any outlet that is near a sink needs to be GFCI.

Does a refrigerator need a GFCI?

You don't need a GFCI outlet for a refrigerator because the outlet would likely go behind the refrigerator, which isn't a wet surface. If it was plugged into a countertop receptacle, for some reason, it would need to be GFCI, but that is not a common situation.

Does a dishwasher need GFCI protection?

Dishwashers generally do not need GFCI protection, or really any appliance, since the outlet would not be near a countertop surface typically. If they are within 6 feet of a sink, however, then yes you would need GFCI protection.

Why does my refrigerator keep tripping my GFCI outlet?

You should put your fridge on a dedicated circuit if you notice it is continually tripping the GFCI outlet. This typically happens when you have multiple appliances plugged into one circuit, which overloads it and causes the GFCI to trip. Try plugging the fridge into a different outlet and see if that fixes the problem.
