Electrical Panel Upgrade Cost
Upgrading an electrical panel from 100 to 200 amps costs $1,300–$1,600 in place, or $1,800–$2,500 with a new service panel. Price your amp jump, fuse-box conversion, and meter box in seconds.
Upgrading an electrical panel from 100 to 200 amps costs $1,300 to $1,600 when the existing panel can be upgraded in place, or $1,800 to $2,500 with a whole new service panel. It's the upgrade hiding behind every EV charger, heat pump, and induction range quote — 200 amps is what modern electric life assumes.
What's the upgrade?
Not sure what you have? The number on the big double breaker at the top of your panel (100, 150, 200) is your current service; round screw-in fuses mean a fuse box. 200 amps is the modern standard — EV chargers, heat pumps, and induction ranges assume it. 60→100 suits older small homes; 400 is for homes stacking EVs, a shop, and electric everything.
Can the existing panel box be upgraded in place?
Your electrician answers this in minutes. Upgrading in place — new guts in the existing box — is the cheaper lane. A new panel is required when the old one is damaged, undersized, being moved, or a Federal Pacific or Zinsco brand, which fail today's safety codes and get replaced on sight.
Does the meter box need replacing too?
The metal box outside holding the utility meter. Old or undersized ones get swapped when service upsizes — your electrician will flag it. Cost scales with amperage.
Cost to upgrade your panel from 100 to 200 amps
$1,300–$1,600
electrician labor, panel and breakers, and permit-ready work — utility service-line changes are separate
Two brand names that change the answer: FPE and Zinsco
Open your panel door and look for Federal Pacific Electric (FPE) or Zinsco — brands installed by the millions from the 1950s–1980s whose breakers can fail to trip on overload. They don't meet today's safety codes, electricians replace them on sight, insurers increasingly ask about them, and finding one moves you into the new-panel lane automatically.
The two calls to make before signing anything
First, your utility: the panel is yours, but the service drop — the wires from the street — is theirs, and if it can't carry the new amperage, that upgrade is a separate conversation with its own cost and timeline. Second, the permit office — or rather, confirm your electrician is pulling the permit. Skipping it risks fines, failed home sales, and insurance problems; a reputable electrician never offers to.
Based on published national ranges: electricians run $40–$100/hour (a full panel replacement takes 8–10 hours), panel hardware retails from about $160, and permits ride inside the quote. Excludes utility service-drop upsizing, whole-house rewiring, new circuits, and relocating the panel. A subpanel — extra breaker space without a service upgrade — runs $500–$1,000 and is sometimes all you need.
💡About this calculator▼
The electrical panel is the quietest bottleneck in the modern house. Every big electrification project — the EV charger, the heat pump, the induction range, the hot tub — arrives with the same fine print: *if your panel has capacity.* For millions of homes still on 100-amp service, it doesn't, which is why the 100-to-200-amp upgrade has become one of the most-quoted electrical jobs in the country.
The good news is that it's cheaper than most people fear. When the existing panel can be upgraded in place — new guts, new breakers, new main — the 100-to-200 jump runs $1,300 to $1,600. When the old panel is damaged, undersized, or one of the recalled brands, a whole new service panel raises that to $1,800 to $2,500. Older small homes making the 60-to-100 jump pay $850–$1,600; big all-electric households pushing to 400 amps pay $2,000–$4,000; and if your basement still has a fuse box with screw-in fuses, converting to breakers runs $1,100–$4,000 and is as much a safety project as a capacity one.
Two names to check before you get quotes: open the panel door and look for Federal Pacific Electric (FPE) or Zinsco. Those brands — installed by the millions from the 1950s through the 1980s — have breakers that can fail to trip on overload, don't meet today's codes, and get replaced on sight.
Pick your upgrade below, answer whether the existing box can stay, and add the meter box if yours is old or undersized — you'll have a range worth holding against your electrician's bid.
The price hangs on two questions: which amp jump you're making, and whether the panel box survives it.
The jump. Each upgrade path carries its own national range: 60→100 amps at $850–$1,100, 100→200 at $1,300–$1,600, 200→400 at $2,000–$4,000, and fuse-box-to-breakers at $1,100–$4,000 (that wide band is capacity — a like-for-like swap sits low, a full 200-amp modernization sits high). These prices cover the electrician's labor (8–10 hours for a full replacement at $40–$100/hour), the panel with main breaker and a standard set of circuit breakers, and permit-ready work.
The panel question. For the 100- and 200-amp jumps, the price splits on whether the existing panel box can be upgraded in place or a new service panel must be hung: $1,300–$1,600 versus $1,800–$2,500 for the 200-amp case. Your electrician answers this in the first five minutes of a site visit — age, condition, location, and brand decide it. The 400-amp and fuse-box paths publish a single range covering both.
The meter box. When service upsizes, the utility meter's enclosure often gets replaced in the same visit — $55–$250 at 100 amps, $85–$680 at 200, $480–$765 at 400. It's the easiest line to forget and the easiest to check: if your meter box is rusty, ancient, or rated below your new service, budget it.
📐How it's calculated▼
Total = panel work + meter box, if it's being replaced.
The panel work is a lookup on your two answers. Going 60 to 100 amps runs $850–$1,100 when the existing box is upgraded in place, or $1,200–$1,600 when a new service panel has to be hung. The classic 100-to-200 jump runs $1,300–$1,600 in place, or $1,800–$2,500 with a new panel. Going 200 to 400 amps runs $2,000–$4,000 either way, and a fuse-box-to-breakers conversion spans $1,100–$4,000, with the capacity you land at deciding where in that band you fall.
Replacing the meter box adds $55–$250 at 100 amps, $85–$680 at 200, or $480–$765 at 400 — the enclosure scales with the service size.
Context for the bands: the national average panel replacement lands at $1,475, with most homeowners spending $1,287–$1,707. The panel hardware itself retails from about $160 — labor is the bulk of every bid at $40–$100/hour, and a full replacement takes 8–10 hours. A subpanel ($500–$1,000) adds breaker spaces without touching your service size, and is sometimes all a full-feeling panel actually needs.
🔍Finding your inputs▼
What's the upgrade? First, find out what you have — it takes thirty seconds. Open your panel door and look at the big double-width breaker at the top: the number stamped on its handle (100, 150, or 200) is your current service size. If you see a column of round, screw-in glass fuses instead of flip switches, you have a fuse box. From there: if you're here because of an EV charger, heat pump, or electrification quote, you're almost certainly looking at 100→200 — that's the jump the modern grid-connected house assumes. Pick 60→100 for older, smaller homes still on tiny service, and 200→400 only if you're stacking multiple EVs, a workshop, or whole-home electric heat.
Can the existing panel box be upgraded in place? Don't agonize — your electrician settles this at the site visit. In-place is the cheaper lane. A new panel becomes mandatory when the existing one is damaged, rusted, in a code-violating location, or branded Federal Pacific or Zinsco. If you already know your brand is one of those two, choose "new service panel."
Does the meter box need replacing too? Walk outside and look: if the box holding your utility meter is rusty, visibly old, or rated below the service you're moving to, say yes. Your electrician or utility will flag it either way, but flagging it yourself now means the bid you compare against includes it.
⚠️Special situations▼
My panel is full but I don't actually need more amps
You may want a subpanel, not a service upgrade. A subpanel ($500–$1,000) adds breaker spaces fed from your existing service — perfect for a finished basement, garage circuits, or a workshop when your total load still fits in 100 or 200 amps. An electrician can do a load calculation to tell you which problem you actually have; it's cheaper than defaulting to the bigger project.
I found "FPE" or "Zinsco" on my panel door
Plan the replacement now rather than during a crisis. These brands' breakers can fail to trip on overload — the one job a breaker exists for — and they no longer meet code. Expect the new-service-panel lane ($1,800–$2,500 for 200-amp service), tell your insurer once it's done (some carriers surcharge or decline homes with FPE panels), and keep the paperwork — it's a resale asset.
The utility says my service drop can't handle 200 amps
This is the scenario that blows up panel-upgrade budgets, and it's entirely utility-controlled: the wires from the street, the transformer, sometimes the mast on your roof. Some utilities upgrade their side free as infrastructure; others bill you, especially for underground service requiring trenching. Get the utility's answer in writing before signing the electrician's contract — the sequencing matters, and a panel rated for amps the street can't deliver helps no one.
I'm upgrading specifically for an EV charger or heat pump
Tell the electrician about every planned load, not just this one — the right panel size is a load calculation across your next decade (second EV? induction range? ADU?), and going 100→200 once costs far less than doing it twice. Also ask about load-management devices: a smart splitter or EV charger with load sharing sometimes squeezes a charger onto existing service and defers the whole upgrade.
Can I replace the panel myself?
This is the wrong project for DIY, and not just legally. The service side of the panel stays energized even with the main breaker off — the only dead panel is one the utility has disconnected at the street. Permits universally require licensed work on service equipment, unpermitted panel work surfaces at home sale and insurance claims, and the failure mode is fire or fatality. The $400–$800 of labor in a typical bid is the best money in the whole project.
❓Common questions▼
How much does it cost to upgrade an electrical panel from 100 to 200 amps?
The 100-to-200-amp upgrade costs $1,300 to $1,600 when the existing panel can be upgraded in place, or $1,800 to $2,500 when a whole new service panel is required — the panel's age, condition, and brand decide which lane you're in. Add $85–$680 if the meter box gets replaced in the same visit. Utility service-drop upgrades, when needed, are separate.
Do I need 200-amp service?
If your home is heading electric, probably. 200 amps is the modern standard, and the loads driving upgrades — EV chargers (typically 40–60 amps), heat pumps, induction ranges, hot tubs — stack up fast against 100-amp service. The honest test is a load calculation by an electrician, not the panel's fullness: a crowded 100-amp panel sometimes just needs a $500–$1,000 subpanel, while a half-empty one can still be over capacity on paper.
How long does an electrical panel upgrade take?
A full panel replacement takes 8 to 10 hours — one long day — including the new panel, main breaker, and a standard set of circuit breakers. Expect the power to be off for most of it, since the utility typically disconnects service at the meter while the panel is swapped. Simpler in-place upgrades run shorter; jobs adding a meter box or waiting on utility coordination can stretch across visits.
What is the cost to replace a fuse box with breakers?
Converting a fuse box to a modern breaker panel costs $1,100 to $4,000, with capacity driving the spread — a like-for-like amperage swap sits at the low end, while bringing the service up to 200 amps at the same time sits high (and is usually the smarter spend, since the labor overlaps). Fuse boxes predate modern electrical loads, and the common workaround of installing bigger fuses is a genuine fire hazard.
Does a panel upgrade require a permit?
Always — and that's protective, not bureaucratic. The permit brings an inspection that verifies the service equipment powering your home was done right, and unpermitted panel work resurfaces at the worst moments: home sales, insurance claims, refinance appraisals. You can be fined for skipping it. A reputable electrician pulls the permit as a matter of course; one who offers to skip it is telling you something.
Will my homeowners insurance care about my electrical panel?
Increasingly, yes. Insurers commonly ask about panel type and service size on older homes, and Federal Pacific (FPE) and Zinsco panels — whose breakers can fail to trip — draw surcharges, remediation requirements, or declined coverage from some carriers. Fuse boxes raise similar flags. After an upgrade, send your insurer the permit and inspection paperwork; it can help your rate, and it papers the file for any future claim.
