What makes up the price
Cost by size
National averages, before any local adjustment. Computed from the same model as the calculator above, so the two always agree.
| Circuits in the panel | Circuits | Typical | Range |
|---|---|---|---|
| 14 circuits | 14 | $2,700 | $2,200 to $3,350 |
| 20 circuits | 20 | $3,000 | $2,450 to $3,700 |
| 24 circuits | 24 | $3,175 | $2,625 to $3,950 |
| 32 circuits | 32 | $3,575 | $2,925 to $4,425 |
| 40 circuits | 40 | $3,975 | $3,250 to $4,925 |
Why two quotes differ by thousands
Almost always because they are not quoting the same job, and the difference has a name that rarely appears on either quote.
Panel only
The existing service cable, mast and meter socket stay. The old load center comes off the wall, a new one goes on, and every circuit is moved across. Around $2,300 for a typical house.
This is only possible if the existing service entrance is already rated for the new panel and is in good condition — which, if the panel is old enough to be replaced, it often is not.
Panel and service entrance
Everything from the weatherhead in: new mast, new meter socket, new service cable, new grounding. Around $3,175, and the usual answer when a 100 amp service becomes a 200 amp one.
Plus utility-side work
If the service drop from the pole, or the underground lateral, has to be upsized, the utility does that part on its own schedule and the electrician works around it. Around $4,300, and several weeks longer.
Ask any electrician which of these three they are quoting. It is the single most useful question on this page.
The amperage is a red herring
A 200 amp load center is under $300 at a big-box store. A 100 amp one is $160. The $140 between them is a rounding error on a $3,000 job.
What actually costs money:
- The circuits. Every one has to be identified, extended if needed, landed and labeled. That is about 18 minutes each, and a typical house has 24 of them.
- The service entrance. Cable, mast, meter socket, two ground rods and the conductor between them — around $420 in parts and most of a day.
- The permit and the inspection, and the wait for both.
- Being without power while it happens, which is four to eight hours.
So going from 100 amp to 200 amp costs almost nothing extra in equipment. If you are replacing a panel at all, there is rarely a good reason to put back a 100 amp service.
When you actually need more capacity
A 100 amp service is genuinely adequate for a house with gas heat, gas water heating and a gas range. It becomes inadequate when things start getting added:
- An EV charger at 40 or 48 amps is the most common trigger.
- A heat pump, especially one replacing a gas furnace.
- An electric range or a heat pump water heater.
- An addition, a shop or an accessory dwelling.
A load calculation is the honest way to answer this, and any electrician proposing a service upgrade should be willing to do one. It is arithmetic on the actual connected load rather than a rule of thumb, and it sometimes shows that an existing 100 amp service is fine and a $3,000 job is not needed.
Panels that are a safety problem, not a capacity one
For some readers this is not an upgrade decision. If your panel is one of these, replacement is a safety matter and the capacity question is secondary.
- Federal Pacific Electric (FPE) Stab-Lok. Breakers that have been shown to fail to trip under overload. Widely installed from the 1950s to the 1980s.
- Zinsco or Sylvania-Zinsco. Breakers that can weld themselves to the bus and fail to trip.
- Challenger, with similar reported failures.
- Fuse boxes, which are not inherently unsafe but are usually attached to wiring of the same age.
Insurers increasingly refuse to cover houses with FPE or Zinsco panels, and home inspectors flag them at sale. If you have one, that is the reason to do this job and the budget question is how, not whether.
Aluminum branch wiring
Separately: houses wired with aluminum branch circuits between about 1965 and 1973 have a connection problem at devices rather than a panel problem. A new panel does not fix it. The accepted remedies are copper pigtails with approved connectors or a rewire, and anybody quoting a panel as the solution has not understood the issue.
What the day looks like
- Power off for four to eight hours. Plan for the refrigerator and anybody working from home.
- The utility pulls the meter at the start and resets it at the end, which has to be booked.
- An inspector has to release the work before the meter goes back, and in some jurisdictions that is a same-day visit and in others it is not.
- Labeling. A properly done panel leaves every circuit identified on the directory. It is the cheapest thing on this list and the most commonly skipped.
Questions worth asking
- Which scope — panel only, panel and service entrance, or utility work too?
- Has a load calculation been done, and what did it show?
- Are AFCI and GFCI breakers included where code now requires them? They are $45-60 each against $10 for a standard breaker, and on a 24 circuit panel that is a real number.
- Who pulls the permit and schedules the inspection?
- How long will the power be off?
- Will the directory be labeled?
Common questions
How much does it cost to upgrade an electrical panel?
Around $3,175 for a 200 amp panel and a new service entrance on a 24 circuit house, with most jobs falling between $2,625 and $3,950. Replacing only the panel and keeping the existing service entrance is closer to $2,300, and work that needs the utility to upsize the service drop is around $4,300.
Why do electrical panel quotes vary so much?
Because they are quoting different scopes under the same name. A panel swap keeps the existing mast, meter socket and service cable; a service upgrade replaces all of it; and a utility-side upgrade adds a new service drop on the utility's schedule. Those three are roughly $2,300, $3,175 and $4,300 for the same house. Asking which one is being quoted is the most useful question you can ask.
Does upgrading from 100 amp to 200 amp cost much more?
Barely anything in equipment — a 200 amp load center is under $300 against $160 for a 100 amp. The cost is in the circuits, the service entrance and the permit, which are the same either way. If you are replacing a panel at all, there is rarely a good reason to put back a 100 amp service.
Do I need a 200 amp service?
Not necessarily. A 100 amp service is genuinely adequate for a house with gas heat, gas water heating and a gas range. It becomes inadequate when an EV charger, a heat pump, an electric range or an addition gets added. A load calculation answers this properly, and any electrician proposing an upgrade should be willing to do one — it sometimes shows the existing service is fine.
Is a Federal Pacific or Zinsco panel dangerous?
Both have documented histories of breakers failing to trip under overload, and both are commonly flagged by home inspectors and increasingly refused by insurers. If you have one, replacement is a safety decision rather than a capacity one, and the question is how to budget for it rather than whether to do it.
How long does a panel upgrade take?
About 15 hours of electrician time for a 24 circuit house, which is usually one long day on site. The power is off for four to eight hours of that. The longer part is scheduling: the utility has to pull and reset the meter, and an inspector has to release the work before it goes back.
Do I need a permit to replace an electrical panel?
Yes, everywhere, and the inspection is not optional — the utility will not reset the meter without it. A permit is typically $150 to $400. Unpermitted service work is both a safety problem and the kind of thing that stops a house sale.
Why is moving the panel so expensive?
Because every circuit in the house has to be extended to reach the new position, usually with a junction box left at the old one. It adds around 40% to the job. If the reason for moving it is cosmetic, it is worth asking whether it is worth that.
What are AFCI and GFCI breakers and do I need them?
Arc-fault and ground-fault breakers, which current code requires on most living-area and wet-location circuits. They cost $45 to $60 each against about $10 for a standard breaker, so on a 24 circuit panel the difference is several hundred dollars. A quote that is notably cheaper than another may be assuming standard breakers where code now requires these.
Will a new panel fix aluminum wiring?
No. Houses wired with aluminum branch circuits between about 1965 and 1973 have a problem at the connections to switches and outlets, not at the panel. The accepted remedies are copper pigtails with approved connectors, or a rewire. Anybody quoting a panel replacement as the fix for aluminum wiring has not understood the issue.
