Most homeowners only think about their electrical panel twice: when a breaker keeps tripping, and when an electrician at a separate job mentions the box is outdated. How much does a new electrical panel cost in 2026 depends on three variables — amp capacity, brand, and whether the meter base, service line, or grounding system need replacing along with the panel. Realistic budgets run from $1,800 for a straightforward 100-amp swap to $7,500 for a 400-amp service upgrade with new mast and meter.
The Quick Answer
National average cost ranges for a full panel replacement in 2026:
- 100-amp panel replacement — $1,800 to $3,200
- 200-amp panel replacement — $2,500 to $4,800
- 200-amp service upgrade from 100-amp — $3,500 to $6,500
- 400-amp panel (large homes) — $5,000 to $9,500
- Sub-panel addition — $1,200 to $2,800
These numbers assume a licensed electrician, permit fees, inspection, and a one-day shutoff. DIY is not legal in most jurisdictions for service-side work, and even where permitted, the savings rarely justify the risk.
What Drives Panel Replacement Cost
Five factors move the quote up or down within those ranges:
Amp capacity — 200-amp service is now the standard for any home over 1,500 sq ft or with central AC. Upgrading from 100A to 200A adds $1,000 to $2,500 because the meter base, service entrance cable, and grounding usually need upgrading too.
Panel brand — Square D QO and Eaton CH are premium brands at $400 to $700 for the panel alone. Siemens and GE run $250 to $450. Bargain panels save $100 to $200 but use cheaper breakers that may not be stocked at every hardware store.
Number of circuits — a 20-space panel costs less than a 40-space. More circuits means more breakers ($8 to $50 each) and more labor terminating them.
AFCI and GFCI requirements — modern code requires AFCI breakers ($40 to $55 each) on most living-space circuits and GFCI breakers ($45 to $65 each) on wet-area circuits. A code-compliant 200A panel typically needs 10 to 15 of these, adding $400 to $900 over standard breakers.
Mast and meter replacement — if the weatherhead, service entrance cable, or meter base are corroded or undersized, expect $800 to $2,000 in additional work.
Labor Breakdown
Labor accounts for roughly 50 to 60 percent of a panel replacement cost. A typical 200-amp swap takes a two-person crew 8 to 12 hours and runs $1,200 to $2,000 in labor.
Labor includes shutting off power at the meter, removing the old panel, installing the new panel and grounding, terminating every existing circuit, installing new breakers, coordinating with the utility for meter reconnection, and the inspection appointment. The work cannot be rushed — every circuit must be properly identified and torqued to specification.
Permits and Inspection
Every jurisdiction in the US requires a permit for panel replacement. Permit fees range from $75 to $400 depending on city and county. Most areas require both an electrical inspection and a final utility inspection before power is restored.
Skipping the permit is a serious mistake. Unpermitted electrical work is a frequent insurance denial point after a fire, and it surfaces during the disclosure process when you sell the home. Always confirm in writing that the electrician pulls the permit.
When You Definitely Need a New Panel
Five conditions make panel replacement essentially mandatory:
- Recalled brand — Federal Pacific Stab-Lok, Zinsco, or Sylvania panels have documented failure rates and should be replaced regardless of age
- Fuse box instead of breakers — fuse boxes max out at 60 amps and cannot support modern loads
- Frequent breaker trips — especially on circuits that should not be overloaded
- Hot panel cover or burning smell — turn off the main breaker immediately and call an electrician same-day
- Adding major loads — EV charger, hot tub, electric vehicle, heat pump conversion, or ADU
If any of these apply, get three written estimates within the same week. Bid spreads on panel work commonly exceed 30 percent.
100-Amp vs. 200-Amp: Which Do You Need?
For a typical 1,500-square-foot home with gas heat and gas water heater, 100 amps is technically adequate. For anything larger, anything all-electric, or any home planning an EV charger in the next five years, 200 amps is the right answer.
The marginal cost of upgrading to 200 amps during a planned panel replacement is $500 to $1,500. Doing it later as a standalone project costs three to five times more because the crew has to re-pull permits and revisit work they would otherwise have done in one trip.
EV Chargers and Future-Proofing
If an electric vehicle is anywhere in your five-year plan, factor in the panel capacity now. A Level 2 home charger draws 30 to 50 amps continuously while charging. Adding it to a marginal 100-amp panel can trip the main breaker; even on a 200-amp panel, it occupies two valuable spaces.
Specify a panel with at least 8 to 12 empty spaces for future expansion, or install a sub-panel in the garage at the same time the main panel is replaced. The combined work runs $3,500 to $5,500 versus $1,800 to $2,800 to add the sub-panel separately a year later.
How to Get an Accurate Estimate
A reliable quote needs three things: an in-person walkthrough (not a phone estimate), a written scope of work listing brand, amperage, breaker count, and any service-side upgrades, and a separate line for permit fees and inspection.
Avoid contractors who quote sight-unseen, refuse to pull permits, or pressure you to decide on the spot. Licensed electricians in every state list their license number on every estimate — verify it on your state’s licensing board website before signing. Spend an hour on this step and you will save thousands on the wrong job done wrong.
