A basic panel-only swap typically runs $1,300 to $3,000, a 100A to 200A service upgrade lands between roughly $1,850 and $5,925 installed, and larger 320/400A service jobs cost more once utility coordination is involved. Labor and utility work drive most of that spread, not the panel itself. Before committing, schedule a licensed electrician for an NEC load calculation and a written permit estimate.
TL;DR:
- The cost of a panel replacement or service upgrade often depends more on utility coordination and labor than on the hardware itself.
- A full 100A to 200A upgrade ranges from $1,850 to $5,925, with labor, utility fees, and permits constituting most of the expense.
- Load-management systems and smart panels can often handle additional loads at a fraction of the cost of a full upgrade, typically $500 to $1,500.
- Proper load calculations may reveal that a smaller upgrade or load management can be enough, avoiding unnecessary utility involvement and costs.
- Utility coordination and permits can add significant delays and costs, often extending project timelines beyond a simple swap.

Typical cost ranges by job type
The dollar figure depends almost entirely on whether the utility company has to touch anything.
- Panel-only replacement: Swapping an old panel for a new one of the same amperage, with no service upgrade, usually costs $1,300 to $3,000. It excludes new circuits, rewiring, or meter work.
- 100A to 200A service upgrade: Installer surveys and cost calculators put this job at roughly $1,850 to $5,925 installed, and separate permit and cost guides describe a typical range of $1,800 to $4,500 depending on complexity. It commonly includes a new meter base, service entrance conductors, permit fees, and utility reconnection.
- 200A to 320/400A upgrade: Needed for large homes, workshops, or multiple high-draw appliances like EV chargers and heat pumps running together, this tends to cost more than a standard 200A job because it often requires heavier service conductors and sometimes a transformer review.
- Subpanel additions: Adding a subpanel to serve a garage, workshop, or addition is often cheaper than a full service upgrade, since it avoids touching the utility connection entirely.
Get quotes based on your actual panel size and planned loads rather than a generic average, since a workshop with a welder behaves nothing like a house adding one ceiling fan.
What affects the final price
Two nearly identical homes can get very different quotes, and the reasons usually come down to a handful of variables.
- Labor rates and hours: Electricians typically charge $50 to $150 per hour, and most panel jobs take four to eight hours of work.
- Utility coordination: When the service drop, meter, or transformer needs upsizing, the utility company's schedule and fees can add real time and cost.
- Permits and code fixes: Inspectors sometimes require AFCI or GFCI breakers, updated grounding, or bonding jumpers before signing off.
- Site complexity: Panel relocation, underground service, older knob-and-tube wiring, or a high circuit count all add hours.
Homeowners should expect a significant portion of a panel upgrade's total cost to be labor, according to NerdWallet's cost breakdown, and that share climbs fast once rewiring or relocation enters the picture. Panel hardware itself is a minor line item next to labor and utility coordination.
Line-item cost breakdown: what you'll actually pay for
A written estimate should separate hardware from labor and fees so you can compare bids apples to apples.
- Panel hardware: A quality 200A loadcenter typically runs $200 to $400, a small fraction of the total job.
- Labor: Most panel jobs need four to eight hours at $50 to $150 per hour, the single biggest line item on most invoices.
- Permit fees: Municipal permit costs typically run $75 to $200, and most jurisdictions require the contractor to pull the permit.
- Meter base and service entrance work: Required whenever amperage increases, and one of the pricier optional-turned-mandatory items on a service upgrade.
- Optional add-ons: Surge protection and extra AFCI breakers are common upsells that some homeowners skip and others consider worth the cost.
- Surprise items: Panel relocation, drywall repair, or feeder cable replacement can appear once a contractor opens the wall, so ask about these possibilities up front.
Alternatives to a service upgrade: load-management and smart panels
Not every added EV charger or heat pump needs a full service upgrade. Load-management systems, permitted under NEC 750, monitor total home demand and shed or throttle circuits to stay under your existing service capacity instead of requiring more amperage from the utility.
- Typical installed cost: Load-management devices and smart panels generally run $500 to $1,500 installed, often avoiding a $2,000 to $4,500 service upgrade.
- When it works: A single EV charger or one new major appliance is a common fit for a code-compliant load-management solution.
- When it doesn't: Multiple EVs, a workshop, or planned future electrification usually justify the larger upgrade instead of managing around a tight limit.
Research summaries from Lawrence Berkeley National Laboratory note that many homes can electrify fully on a 100A panel with correct load calculations and load management, even though a full utility-side upgrade remains slow and costly when it is genuinely needed.
Pro Tip: Ask your electrician to run the numbers both ways, a load-management device versus a full upgrade, before you decide.
Timeline, permits, and the utility coordination you should expect
A like-for-like panel swap is usually a one-day job. A full service upgrade takes longer once permits and the utility get involved.
- On-site work: Expect one day for a simple swap, and one to two days for a full 100A to 200A upgrade.
- Permits and inspection: The contractor typically pulls the permit, and inspection scheduling can add days to weeks depending on your municipality.
- Utility disconnect and reconnect: The utility company disconnects service before the new equipment goes in and reconnects it after inspection passes, and scheduling a transformer or service-drop change can be the slowest part of the whole project.
Tax credits, rebates, and programs that can offset costs
Some panel-related upgrades qualify for savings if the work supports specific efficiency or electrification goals.
- Federal tax credits: ENERGY STAR documents federal tax credit programs that can offset panel and wiring costs tied to eligible equipment, subject to annual aggregate limits.
- State and utility rebates: Check the ENERGY STAR rebate finder or your state energy office for local electrification rebates, since availability varies widely by location.
- Claiming steps: Keep every invoice, confirm your equipment qualifies before you buy it, and consider spreading eligible upgrades across tax years if you're near an annual limit.
Some panel and wiring upgrades qualify for federal tax credits with annual program limits, according to ENERGY STAR's federal tax credit guidance, so it pays to check eligibility before the work starts rather than after the invoice is paid.
Contractor checklist: preparing for an accurate quote
Before calling an electrician, gather clear photos of your existing panel and its service label, plus a list of major appliances and any planned additions like an EV charger or workshop equipment. That preparation lets a contractor give you a realistic number instead of a rough guess over the phone.
When comparing bids, ask each electrician for the NEC load calculation behind their recommendation, confirm who pulls the permit, and ask about warranty terms and expected timeline. Also ask directly who is responsible for utility coordination, since that answer changes both the schedule and the price. Estimates are typically built around a photo-based consultation followed by a written quote, drawing on local permitting experience to set realistic timelines before work begins.
Why the real decision isn't about panel price at all
The conventional advice on this topic treats the panel swap number as the headline figure, when the number that actually matters is whether your project needs the utility involved at all. Two homeowners can get quotes that differ by $3,000 for reasons that have nothing to do with the electrician's skill and everything to do with whether a service drop needs upsizing.
Most homeowners should ask for the load calculation first and the price second. A documented NEC 220 calculation can reveal that a load-management device solves the problem for a fraction of a full service upgrade, and it protects you from paying for capacity you'll never use. The industry defaults toward recommending the bigger upgrade because it's the safer sell for a contractor, not always because it's the cheaper path for you. Ask for the math before you ask for the invoice.

FAQ
How much does it cost to upgrade an electrical panel from 100 to 200 amps?
A 100A to 200A service upgrade typically costs $1,850 to $5,925 installed, or roughly $1,800 to $4,500 in many typical cases. The final price depends on utility coordination, permit fees, and whether the panel needs to be relocated.
How much do electricians charge to change a panel?
Electricians generally charge $50 to $150 per hour, and most panel jobs take four to eight hours. Labor typically makes up at least $1,000 of the total project cost, more if rewiring or relocation is involved.
Does upgrading to 200-amp service increase home value?
A 200A service is now standard for many newer homes and can make a house easier to sell to buyers planning an EV charger, heat pump, or major appliances, though no source in this guide quantifies a specific resale value increase. Think of it as removing a buyer objection rather than as a guaranteed dollar return.
Do I need a full 200-amp service, or can I use a load-management device instead?
A load-management device installed under NEC 750 can be a code-compliant alternative for many homes adding one major load like an EV charger, and it typically costs $500 to $1,500. If you're planning multiple EVs, a workshop, or other permanent high-draw equipment, a full service upgrade is usually the better long-term fit.
What unexpected costs come up during a panel upgrade?
Common surprises include panel relocation, drywall repair, and feeder cable replacement once a contractor opens the wall and finds outdated wiring. Asking your electrician about these possibilities before work starts helps you budget for them instead of being surprised mid-project.
