Electrical Panel Upgrade Cost: Prices by Amp Service
Upgrading an electrical panel costs most homeowners $1,300 to $3,000 for standard 200 amp service, though national estimates span $518 to $4,500 depending on how much of the service entrance has to be replaced. Labor, not the panel itself, drives the price.
What an electrical panel upgrade costs
National cost guides disagree more than usual on this project, and the spread tells you something useful. This Old House puts panel upgrades at $800 to $4,000, with most homeowners paying $1,300 to $3,000 to move up to 200 amp service. HomeAdvisor reports a lower typical band of $518 to $2,192 with an average of $1,346. Fixr sits higher, at a $1,500 to $4,500 national range with most homeowners around $3,000.
These are not contradictory so much as they are measuring different jobs. The low figures describe swapping a panel in place while keeping the existing service entrance. The high figures include a new meter socket, new service cable, updated grounding, and permits. When you compare bids, the first thing to establish is which of those two jobs you are actually buying.
Cost by amperage
| Service size | Panel only | Panel plus installation | New install, no existing panel |
|---|---|---|---|
| 100 amp | $100 – $200 | $800 – $1,500 | $1,200 – $1,600 |
| 200 amp | $250 – $350 | $1,300 – $3,000 | $1,800 – $2,500 |
| 300 amp | $350 – $500 | $1,800 – $3,500 | $2,000 – $4,500 |
| 400 amp | $500+ | $2,000 – $4,000 | $4,000 – $6,000 |
Look at the first column against the second and the real story appears. A 200 amp panel is a $250 to $350 part. Everything else in the $1,300 to $3,000 installed price is labor, permits, and materials around the panel. That is why upgrading from 100 to 200 amps often costs barely more than replacing a 100 amp panel with another one: the electrician does nearly the same work either way.
Why labor dominates the bill
Electricians charge $40 to $250 per hour, and a typical panel upgrade takes 4 to 8 hours, not counting any rewiring. HomeAdvisor puts typical project labor around $1,500. Costs climb when the job involves relocating circuits, upgrading the service line from the utility, or working in a cramped space.
Several related items commonly appear on the same invoice. Replacing a main breaker runs $200 to $300, or $500 to $2,000 if the bus bar is damaged. Adding a subpanel costs $400 to $1,750 and can sometimes add capacity to one area without touching the main panel. Moving the panel to a new location costs $800 to $3,000. Replacing an old fuse box with a breaker box runs $1,500 to $2,000, or up to $4,500 if the wiring needs a full overhaul. Budget another $150 to $300 for permits and the drywall repair cost after the electrician opens up walls.
What size panel you need
Most homes built since 2015 have at least 200 amp service, and that has been the practical standard since the 1980s. Houses from the post war boom often started at 50 or 60 amps, and 1960s and 1970s homes frequently topped out at 100 or 150. Panels last 25 to 40 years, but age is rarely what forces the decision. Rising demand is.
The right size comes from a load calculation a licensed electrician performs, not from square footage alone. It accounts for heating and cooling equipment, cooking appliances, and anything else drawing heavily. Plan for what you are about to add, not just what you run today. An EV charger, a hot tub, a finished basement, or new HVAC equipment can each push a home past what its panel can carry. Signs you are already at the limit include breakers that trip often, lights that dim when a large appliance starts, buzzing or warmth at the panel, and visible corrosion. Federal Pacific Electric and Zinsco panels are worth replacing on safety grounds regardless of capacity.
Is your quote reasonable?
For a straightforward 100 to 200 amp upgrade with the panel staying where it is, a quote in the $1,300 to $3,000 range is normal. Under $1,300 usually means a like for like swap with no service entrance work, which may be all you need. Above $3,000 should come with named reasons: a new meter socket and service cable, utility coordination, a panel relocation, or substantial rewiring.
Ask the electrician four questions before signing. Is the permit included and who files it? Does the price cover the meter socket and service cable, or only the panel? Was a load calculation performed, and what does it show? Is patching and painting after the work included or billed separately? Also confirm the electrician is licensed and the work will be inspected. This is not a job where a cheaper unpermitted bid saves money, because an uninspected panel can surface later as an insurance problem or a fire risk.
