Circuit Breaker Replacement Cost (2026 Data & Averages)

Replacing a single circuit breaker costs $130 to $300 in 2026 with a licensed electrician, and the national average lands near $200. The breaker itself is the cheap part — $5 to $20 for a standard breaker, up to $70 for a GFCI or AFCI, and $100 or more for a main breaker — while the other 70 to 80% of the bill is labor and the electrician's $100-$200 service-call fee.

In 18 years of running residential service calls, I have swapped more failed breakers than I can count, and the conversation is almost always the same: the homeowner saw a $12 part on the hardware-store shelf and cannot make sense of the $190 invoice. On one Square D Homeline job last spring, the breaker was $14 and the other $176 was my truck roll, my one-hour minimum, and the ten minutes of actual work it took to pull the dead breaker and seat the new one. The part is never the story — the trip is.

This is the averages-and-data companion to the calculator. The tool prices your exact job; this page gives you the 2026 national benchmarks every quote should fall inside, so you can spot an overcharge before you sign. If you are adding a brand-new circuit rather than swapping a breaker in an existing panel, that is a different and bigger job — jump to the scope section below or price it with the circuit installation cost calculator.

Circuit Breaker Replacement Cost at a Glance (2026)

The single biggest cost swing on a breaker replacement is the breaker type. A standard single-pole 120V breaker is a $5-$20 part; a GFCI, AFCI, or dual-function CAFCI breaker contains internal arc-fault or ground-fault sensing electronics and costs 5 to 10 times more. Here is the 2026 national picture, cross-checked against HomeGuide, Homewyse, and Angi cost surveys updated through early 2026. In every row, the breaker part plus the labor-and-service-call column equals the installed total.

A "replacement" here means a like-for-like swap: same amperage, same panel slot, same brand, with the wire and outlet already in place. That is the $120-$400 job in the table above. The moment new wire, a new outlet, or a higher amperage enters the picture, you leave the breaker-swap band entirely — covered in the scope section below.

What You Are Actually Paying For: Part vs Labor vs Service Call

The reason a $12 breaker costs $190 installed is that the breaker hardware is the smallest line on the invoice. Nearly every licensed electrician in 2026 charges a $100-$200 minimum service-call fee just to roll a truck and walk in the door, and most bill a one-hour minimum on top of it at $50-$130 per hour. The actual on-tools work — popping the panel cover, pulling the old breaker, seating the new one, testing — is 15 to 30 minutes. Here is how a typical standard breaker swap decomposes:

The low column sums to $130 and the high column to $230, which is exactly the standard-breaker band. The takeaway is structural: because the service-call fee dominates, the cheapest way to cut your per-breaker cost is to never send an electrician out for one breaker alone.

GFCI, AFCI, and CAFCI Breakers: Why Specialty Breakers Cost 2-4x More

A standard breaker just trips on overcurrent. A GFCI breaker adds ground-fault sensing, an AFCI breaker adds arc-fault sensing, and a dual-function CAFCI does both — and that internal electronics package is what drives the price. A standard single-pole breaker is $5-$20 of hardware; an AFCI is $40-$60, a GFCI is $40-$70, and a CAFCI is $50-$80. The labor stays roughly flat because the install time is the same once the panel is open, so the price delta you see is almost entirely the part.

The big external driver here is code. NEC 210.12 (NFPA 70) has required AFCI protection on most 15A and 20A 120V branch circuits in bedrooms, living rooms, dining rooms, hallways, closets, and laundry areas since the 2014 cycle. That is why homeowners buying a 1990s or early-2000s house routinely get flagged on a home inspection and asked to retrofit AFCI breakers — typically three to six breakers at $180-$280 each, or a bundled $600-$1,400 visit. GFCI breakers run higher installed ($300-$375) than AFCI because they often need a load-neutral pigtail moved during the swap, which adds a few minutes per breaker.

Double-Pole, Tandem, and Main Breaker Replacement

Not every breaker is a single-pole 120V. Three other types show up regularly on service calls, and each has its own price band:

• Double-pole 240V breakers feed dryers, ranges, water heaters, and AC condensers. They take two panel slots, cost $25-$80 for hardware, and run $200-$400 installed. No new wire is being pulled on a swap — the existing 6/3 or 10/3 cable stays put.
• Tandem (half-size) breakers squeeze two circuits into one slot and run $150-$300 installed. The catch is compatibility: some Square D QOC panels do not accept tandems at their UL listing, so an electrician must check the panel's interior label before ordering one.
• Main breaker replacement is the expensive outlier. The main is the big breaker at the top of the panel that feeds everything. Hardware alone is $100-$300 (more for high-amp or specialty units), and installed it runs $300-$800 because the job requires de-energizing the whole house at the utility disconnect — often a separate $75-$150 utility service call.

Can You Replace a Circuit Breaker Yourself? DIY vs Electrician

This is the question I get most, and the honest answer is: the part is cheap and the swap is mechanically simple, but the panel is the one place in a house where a mistake can kill you. The main lugs at the top of the panel stay energized even with the main breaker switched OFF — only the utility can fully de-energize the panel. Electricians use insulated tools and arc-rated PPE for exactly this reason.

The DIY math looks tempting — you save roughly $120-$210 in labor — but the downside is asymmetric. A wrong-brand breaker (a Siemens dropped into a Square D panel to save $15) voids the panel's UL listing, gets flagged on a resale inspection, and can void your homeowner's insurance on any future electrical fire on that circuit. For most people, paying the $130-$230 for a licensed swap is the right call. If you do swap one yourself, match the brand and amperage exactly and never touch the main lugs.

Circuit Breaker Replacement Cost by Region

After breaker type, regional labor is the biggest swing factor. A licensed electrician charges $50-$130 per hour in most of the country, but that climbs to $150 and up in dense metros like New York City and San Francisco, per HomeGuide's 2026 electrician labor data. Stack the hourly rate on the service-call fee and the same standard swap can cost 50% more on one coast than the other.

When a Breaker Swap Becomes a Bigger Job

A breaker swap assumes the wire, the outlet, and the panel capacity already exist. When any of those is missing, the job leaves the $100-$400 band fast. This is the most common pricing surprise I see, so confirm your scope against this table before you budget:

Three scenarios routinely escalate a $200 swap into a four-figure project. First, an amperage upgrade the wire cannot support — swapping a 15A breaker for a 20A on 14-gauge Romex is a fire hazard, because the wire overheats before the bigger breaker trips. 15A circuits need 14 AWG, 20A need 12 AWG, 30A need 10 AWG; if the wire does not match, the job becomes a new-circuit install. Second, a full panel with no open or tandem-capable slots — you cannot add a breaker until the panel is upgraded or a subpanel is installed. Third, an obsolete Federal Pacific or Zinsco panel, where the panel itself is the safety issue and a breaker swap solves nothing.

When Should a Breaker Be Replaced vs Just Reset?

Most "bad breaker" calls are not a bad breaker at all — they are a circuit doing its job. A breaker that trips and resets cleanly is protecting you from an overload or a fault downstream, and replacing it fixes nothing. Replace the breaker only when the breaker itself has failed. The tells: it will not reset at all, it trips immediately with nothing plugged in, it feels hot or smells of burnt plastic, or it is visibly scorched. A breaker that trips repeatedly under a known heavy load (a space heater plus a microwave on the same 15A kitchen circuit) is working correctly — the fix is redistributing the load or adding a circuit, not a new breaker.

Breakers do wear out, but slowly — a quality breaker lasts 30-40 years, and most replacements are driven by failure, a code retrofit, or a panel upgrade rather than age alone. If you are tripping the same breaker weekly, price a dedicated circuit with the circuit installation cost calculator instead of replacing a breaker that is doing exactly what it should.

How to Use the Circuit Breaker Cost Calculator

The averages on this page are the national picture; the calculator turns them into a number for your panel. Here is the fastest path:

1. Pick the breaker type — standard, AFCI, GFCI, CAFCI, tandem, or 240V double-pole. This sets the hardware cost.
2. Set the amperage — 15A to 60A for branch breakers. The amperage barely moves a swap price unless you are also changing wire.
3. Choose the panel brand — Square D, Siemens, Eaton, or GE. Brand affects breaker availability and price.
4. Enter how many breakers you are swapping in one visit. This is where bundling savings show up.
5. Add your ZIP to apply the regional labor multiplier so the estimate reflects your metro, not a national average.

Try the circuit breaker install cost calculator now, then compare its number to any written quote you get. Anything more than 20% above the estimate on a like-for-like swap deserves a line-item breakdown.

Frequently Asked Questions

How much does it cost to replace a circuit breaker?

Replacing a single circuit breaker costs $130 to $300 in 2026 with a licensed electrician, averaging near $200, with the breaker part running just $5-$20 for a standard unit and the rest going to labor and the $100-$200 service-call fee. Specialty breakers cost more: GFCI and CAFCI reach $300-$400 installed. Get a ZIP-specific figure from the circuit breaker install cost calculator.

Can I replace a circuit breaker myself?

You can legally replace a like-for-like breaker yourself in most jurisdictions for the $5-$20 cost of the part, but the panel's main lugs stay energized even with the main switched off, so an arc-flash mistake can be fatal — most homeowners are better off paying $130-$230 for a licensed swap. Always match the breaker brand and amperage exactly, because a wrong-brand breaker voids the panel's UL listing and your insurance.

Why does a circuit breaker cost so much more than the part?

Because the part is the smallest line on the bill — a standard breaker is $5-$20, but the electrician's $100-$200 service-call fee plus a one-hour labor minimum makes up 60-75% of a single-breaker invoice. That is why a $12 breaker costs $190 installed, and why bundling two or three breakers in one visit cuts the per-breaker cost 20-40%.

How much is a GFCI or AFCI breaker to replace?

A GFCI breaker runs $300-$375 installed and an AFCI runs $180-$280 in 2026, versus $120-$220 for a standard breaker, because the GFCI and AFCI hardware contains arc-fault or ground-fault sensing electronics that cost 5-8 times more than a standard breaker. A dual-function CAFCI, which does both, runs $300-$400 installed and is often required by NEC 210.12 on bedroom and living-area circuits.

When should a breaker be replaced versus just reset?

Replace a breaker only when it has actually failed — it will not reset, it trips with nothing plugged in, or it feels hot, smells burnt, or looks scorched — because a breaker that trips and resets cleanly is correctly protecting an overloaded circuit and does not need replacing. A quality breaker lasts 30-40 years, so frequent tripping under heavy load usually means you need a dedicated circuit, not a new breaker.

How much does it cost to replace a main breaker?

Replacing a main breaker costs $300-$800 in 2026 — far more than the $130-$230 for a branch breaker — because the main hardware alone is $100-$300 and the job requires the utility to de-energize the entire house, often a separate $75-$150 service call. If the panel is old enough that the main is failing, it is often worth pricing a full panel upgrade instead.

Do I need a permit to replace a circuit breaker?

A like-for-like breaker swap usually needs no permit because most jurisdictions treat it as a repair, but you do need a permit ($50-$150) when you upgrade amperage, add AFCI or GFCI protection a circuit lacked before, or work inside an obsolete Federal Pacific or Zinsco panel. Always confirm with your local building department before a DIY swap, because an unpermitted amperage change can surface as a resale disclosure problem.
