Electrical Panel Upgrade Cost: 100, 200 and 400-Amp Prices (3 References)

Upgrading an electrical panel costs $850 to $4,500 for most homes, with 200-amp service the common target.¹² Angi’s replacement average is $1,347; HomeGuide’s breaker-box average is $1,475; Fixr’s national average for a 100-to-200-amp upgrade is $3,000.¹²³ Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on amperage, wiring condition, permits, and whether the panel moves. This is licensed-electrician work, not a DIY project.

$1,300 – $1,600

100 to 200-amp upgrade, HomeGuide

Quick math: the three references disagree on a 200-amp upgrade. HomeGuide says $1,300 to $1,600 (or $1,800 to $2,500 with a new service panel), Fixr says $1,800 to $4,500, and Angi’s $1,347 replacement average sits with HomeGuide.¹²³ Fixr’s band assumes more rewiring; for a same-spot swap on healthy wiring, $1,300 to $2,500 is the realistic planning range, our judgment from the overlap.

Cost by amperage

Upgrade target	HomeGuide	Fixr (labor included)
To 100 amps	$850 – $1,100 (from 60A)	$1,200 – $1,800
To 150 amps	—	$1,500 – $2,800
To 200 amps	$1,300 – $1,600 (from 100A)	$1,800 – $4,500
To 400 amps	$2,000 – $4,000 (from 200A)	$8,000 – $12,000

The 400-amp rows disagree by a factor of two to four — Fixr’s figure includes new panel placement and substantial new wiring, while HomeGuide’s is a straighter swap.²³ The panel hardware itself is cheap: Angi puts a 200-amp box at $250 to $350 parts-only ($100 to $200 for 100 amps, $500+ for 400 amps).¹ HomeGuide found 200-amp panels retailing for $41 (16-space) to $387 (42-space) at home improvement stores.²

Cost by component

Component	Cost	Source
Main breaker panel	$500 – $2,000	Angi
Fuse box replacement	$1,500 – $2,000	Angi
Main lug panel	$400 – $1,750	Angi
Subpanel	$400 – $2,000 (Angi); $500 – $1,000 (HomeGuide)	Both
Single breaker switch	$100 – $200 installed; $5 – $20 parts	Angi
Electric meter box	$100 – $650	Angi

Breaker type changes parts cost: a standard breaker runs about $10, while GFCI and AFCI breakers run $30 to $100 each — a panel full of code-required AFCI breakers adds real money.¹

Labor

Labor is most of the bill, but the references disagree on hours. Angi says panel replacement with associated components takes at least 20 hours, sometimes 30+, at $50 to $150 per hour — $1,000 to $4,500 in labor.¹ HomeGuide says the job takes 8 to 10 hours at $40 to $100 per hour — $400 to $800 in labor.² Fixr says 4 to 8 hours with two electricians at $40 to $120 per hour.³ The gap is scope: Angi’s figure assumes wiring updates and component work around the swap, while HomeGuide and Fixr describe the panel swap itself.

Permits and extras

Electrical permits run $50 to $300 and usually include the post-job inspection (Angi).¹ Opening walls adds drywall repair at $1.50 to $3 per square foot; replacing faulty wiring runs $600 to $4,500; adding an outlet is $125 to $200; trenching for a new feed is $600 to $2,100 (Angi).¹ Fixr’s $12,000 high-end — a 400-amp upgrade with new panel placement and substantial new wiring — shows how fast the extras stack.³

Worked examples

Example 1 — standard 100-to-200-amp upgrade, panel stays put. HomeGuide: $1,300 to $1,600, or $1,800 to $2,500 if a new service panel is needed.² Fixr: $1,800 to $4,500, averaging $3,000.³ Plan on $1,300 to $3,000 depending on wiring condition, our judgment from the three bands.

Example 2 — fuse box swapped for a breaker panel. Angi prices the fuse box replacement at $1,500 to $2,000, landing right at its $1,347 to $2,193 replacement band.¹

Example 3 — average job with common extras. Angi’s $1,347 average replacement + permit ($50 to $300) + 50 sq. ft. of drywall repair ($75 to $150, our arithmetic at $1.50 to $3 per foot) + faulty wiring found mid-job ($600 to $4,500) = roughly $2,072 to $6,297 all-in, our arithmetic.¹

FAQ

How much does it cost to upgrade to 200-amp service? $1,300 to $1,600 for a like-for-spot upgrade, $1,800 to $2,500 with a new service panel (HomeGuide); Fixr’s band runs higher at $1,800 to $4,500 because it assumes more rewiring.²³

Can I replace an electrical panel myself? No. Angi is explicit that panel replacement is not safe as DIY — it requires a licensed electrician and a permit with inspection.¹

How long does the job take? 4 to 10 hours for the swap itself (Fixr, HomeGuide); Angi’s 20-to-30-hour figure includes associated wiring and component work.¹²³

Why is 400-amp so much more? The box alone is $500+ (Angi), and the upgrade usually means new service wiring — Fixr’s $8,000 to $12,000 band assumes that full scope, HomeGuide’s $2,000 to $4,000 assumes less.¹²³

What adds cost beyond the quote? Permits ($50 to $300), drywall repair ($1.50 to $3 per sq. ft.), wiring replacement ($600 to $4,500), and meter box work ($100 to $650), all per Angi.¹
