Panel upgrades catch most homeowners off guard on cost, and the quotes that come back can vary by thousands of dollars for what sounds like the same job. That gap is almost always explainable — labor markets, panel location, service entrance condition, and permit fees all move independently. This guide breaks each one down so you can read a quote and know what's in it.
A straight panel swap at the same amperage runs $1,200–$2,500. A 200A→400A upgrade — needed for large homes with solar, battery storage, and multiple EVs — starts around $3,000 and can reach $8,000+ when service entrance and utility work are involved.
Cost by Upgrade Type
| Upgrade Type | Typical Cost Range | What's Included |
|---|---|---|
| 100A → 200A upgrade | $1,500–$3,500 | New panel, service entrance work, permit, utility coordination |
| 200A panel swap (same amperage) | $1,200–$2,500 | New panel, permit — no service entrance change required |
| 200A → 400A upgrade | $3,000–$8,000+ | New panel, new service entrance, utility work, permit |
| Fuse box → breaker panel conversion | $1,500–$4,000 | New panel, service entrance likely replaced, permit |
| Add sub-panel only | $500–$1,800 | Sub-panel + feeder circuit — no main service change |
| Replace single circuit breaker | $150–$300 | Labor + breaker — only if the panel itself is sound |
All ranges above assume licensed, permit-pulled work. DIY electrical panel work is illegal in most jurisdictions and will void homeowner's insurance. A permit is always required — see the FAQ below for what that process looks like.
What the Labor Breakdown Looks Like
The cost table above shows the total. Here's what's inside a typical 100A→200A upgrade invoice:
| Line Item | Typical Cost | Notes |
|---|---|---|
| Electrician labor (8–12 hrs) | $800–$1,800 | Master electrician rate + helper; varies by region |
| New 200A panel (materials) | $200–$600 | Square D, Leviton, Eaton — brand matters less than installation quality |
| Permit fee | $75–$500 | Set by municipality — always required, cannot be skipped |
| Utility coordination / reconnection | $0–$500 | Utility-handled at no charge in most areas; some charge a reconnection fee |
| Meter base / service entrance work | $200–$800 | Required when upgrading amperage; usually not needed for a straight swap |

What Drives Costs Above the Typical Range
- Panel in a hard-to-access location. Inside a finished wall, in a tight mechanical room, or mounted unusually high — each adds labor time.
- Service entrance needs replacement. Older homes often have undersized conduit or aluminum wiring at the service entrance that must be upgraded when the panel changes. This is the single most common reason a quote comes in high.
- Meter relocation. If the meter needs to move for an addition, detached garage, or utility requirement, that adds $500–$2,000 to the job.
- Recalled panel brand (Federal Pacific, Zinsco). These require additional safety protocols, and some contractors charge a modest premium. More importantly, many insurers won't renew coverage until they're replaced — so the cost of not replacing them is real.
- Coastal or high-wage markets. Labor rates in LA, NYC, Miami, and Seattle run 20–40% above the national average. If you're in one of these markets, add that multiplier to any national estimate you find online.
Sub-Panel vs. Full Upgrade: The Cheaper Fork
If the trigger is one specific area of the house — a detached garage, a home addition, or an EV charger on the far side of the property — adding a sub-panel is worth pricing before committing to a full service upgrade. A sub-panel runs $500–$1,800 and doesn't require utility coordination or service entrance work. The trade-off: it doesn't add capacity to your main service, so if the main panel is already maxed out, a sub-panel won't help.

Regional Labor Index
| Region | Relative Labor Cost | Typical 200A Upgrade Range |
|---|---|---|
| Northeast (NY, MA, CT) | +25–40% above national avg | $2,200–$5,000 |
| West Coast (CA, WA, OR) | +20–35% above national avg | $2,000–$4,800 |
| Midwest (OH, IL, MI) | Near national average | $1,400–$3,200 |
| Southeast (FL, GA, NC, TN) | 5–15% below national avg | $1,200–$2,800 |
| Southwest (TX, AZ, CO) | Near to slightly below avg | $1,300–$3,000 |
Upgrade vs. Replace: When Replacement Is Actually Cheaper
If your panel is 25+ years old, a full replacement often makes more financial sense than repairing or partially upgrading it. A new panel comes with a 10-year warranty and a fresh inspection, and once labor is already involved, the difference in materials cost between a repair and a full swap is often small. A straight 200A-for-200A replacement typically costs $1,200–$2,500 — and eliminates the question of whether the existing unit will pass inspection.

How to Get Accurate Quotes
The 3-bid approach is standard advice, but knowing what to compare matters more than the number of bids. Ask each electrician to itemize: labor hours, materials with brand, permit fee, and whether utility coordination is included. A low bid that excludes the permit is not actually cheaper — permits are legally required and the cost is real.
Also verify the contractor's license and insurance before anyone pulls a permit. In most states, only licensed master electricians can pull electrical permits for panel work. For a full list of what to ask and red flags to watch for, see: How to Hire an Electrician for a Panel Upgrade.
Financing and Rebate Options
If upfront cost is a barrier, three options are worth investigating:
- IRA Section 25C tax credit — up to $600 for a panel upgrade when it enables a qualifying appliance (heat pump or EV charger). Eligibility conditions apply; consult a tax professional and see our full tax credit guide for current status.
- State and utility rebates — several states and utilities offer separate rebates for panel upgrades tied to electrification. These layer on top of the federal credit in some cases. See our full rebate guide.
- Contractor financing — many electricians offer financing through GreenSky, Mosaic, or similar programs. Rates and terms vary; read the fine print before signing.
