Electrical Panel Upgrade Cost Calculator

Upgrading an electrical panel typically costs about $1,300–$4,500 for a standard 100-to-200-amp service, and more for a 200-to-400-amp upgrade or a brand-new service. The formula the calculator runs is: total = panel + breakers + electrician labor + meter/mast (if needed) + permit & inspection. The amperage tier is the biggest driver. The panel and breakers are nationally-priced equipment, so only the labor-like costs scale with your region, and a permit plus inspection always applies to a real job. This guide walks the exact math and a worked example. Every figure is an estimate, not a quote.

The Amperage Tier Is the Driver

What moves the price most is how big a service jump you're making. Going from 100 to 150 amps is the smallest job. The most common upgrade — 100 to 200 amps — is the calculator's reference and typically runs $1,300–$4,500 all-in depending on the rest of the work. Jumping from 200 to 400 amps is a much bigger job, with a larger panel, heavier wire, and more labor. A brand-new service (where none existed) sits in between, since it adds a service drop and entrance.

The calculator prices the tier as a relative multiplier on an editable panel and labor base, so switching tiers moves both the equipment and the labor lines together.

• 100→200A standard ≈ $1,300–$4,500 all-in
• 200→400A costs more (bigger panel, heavier wire, more labor)
• Tier sets both the panel and the labor baseline

Meter, Mast, and Extra Circuits

Beyond the panel swap, two add-ons can move the number a lot. Replacing the meter and, especially, the service mast or entrance (the overhead conduit and weatherhead) is real extra work — each is priced as hardware plus install. If the upgrade requires a new mast, expect a meaningful jump.

Adding circuits is a lighter add-on: each new circuit is a breaker plus a bit of labor. The calculator lets you add circuits to capture a panel upgrade that also branches out to new loads, like an EV charger or a finished basement.

• Meter replacement = hardware + install
• Service mast / entrance upgrade is a big add
• Each added circuit = a breaker + labor

What Your Region Changes — and What It Doesn't

A panel, its breakers, the meter, and the mast are nationally-priced manufactured goods — they cost about the same everywhere. So the calculator does NOT scale the equipment by your region. What it scales is the labor-like side: the electrician's time, the install, and the permit and inspection fees, which all track local costs.

That's why the same 200-amp upgrade can total more in a high-cost metro than a rural county — the panel is the same, but the licensed-electrician hours and the permit cost more. Pick your state and only the labor-like lines move.

• Panel, breakers, meter, mast = commodity (not region-scaled)
• Electrician labor + permit + inspection = region-scaled
• Same panel, different metro = different labor, same equipment

Permit and Inspection Are Not Optional

A panel upgrade is permitted work everywhere. Pulling a permit and passing inspection protects you and is required for insurance and resale — skipping it is never worth it. The calculator always includes a permit-and-inspection line for a real job, scaled to your region.

Always hire a licensed electrician for panel work. This is not a DIY project: it involves the service entrance and the utility connection, and getting it wrong is a fire and electrocution risk.

• Permit + inspection always applies — it's in the estimate
• Required for insurance, resale, and safety
• Panel work is licensed-electrician work, never DIY

Worked Example: A 100→200A Upgrade

Take a 100-to-200-amp upgrade with a standard main breaker panel, keeping the existing meter and mast, no extra circuits, at the national-average region.

The panel and breakers are $500. Electrician labor is $1,300. There's no meter or mast work. Permit and inspection add $350. That totals $2,150. Add a meter and a new service mast and the meter/mast line adds about $1,200, pushing the total near $3,350 — and stepping up to a 200-to-400-amp tier roughly doubles the panel and adds labor on top.

• Panel + breakers: $500 · Labor: $1,300 · Permit: $350
• Total: $2,150 (bare 100→200A)
• Add meter + mast: ~+$1,200 → ~$3,350

Why the Total Is a Range

Panel upgrades vary with the condition of the existing wiring, the panel location, and local code requirements, so the calculator brackets the realistic figure with a low end at 0.85x and a high end at 1.5x. The upside covers surprises like aluminum wiring that needs pigtailing, a panel in a hard-to-reach spot, code-required arc-fault or surge protection, or utility coordination for a service change.

Budget toward the middle for a clean, straightforward swap and toward the top if your home is older or the panel feeds a lot of circuits. Always get an on-site quote from a licensed electrician before committing.

• Low = realistic x 0.85 · high = realistic x 1.5
• Upside covers old wiring, code add-ons, and utility coordination
• Older homes and full panels push toward the high end

The bottom line

Electrical panel upgrade cost is driven first by the amperage tier — 100→150A smallest, 100→200A the common standard, 200→400A and new service the most — then by whether you also replace the meter or service mast and how many circuits you add. The panel and breakers are nationally-priced equipment, so your region scales only the electrician labor and the permit and inspection. The Electrical Panel Upgrade Cost Calculator runs all of it and returns a panel, labor, meter/mast, and permit breakdown with an honest low-to-high range — a planning number to size up the job and read a licensed electrician's quote against, not a guaranteed bid.
