Notes
- Where the number comes from. The national price for a 100-amp panel upgrade is $1,700 installed — service panel upgrade pricing published for 2026. Labor is about 68% of that. Electricians near San Jose, CA average $99,650 a year against a U.S. mean of $71,490 — a factor of 1.394 — so the labor half is scaled by that and the material half is not.

- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- What is in the price: the panel, breakers, a new meter base, grounding electrodes, the service mast, permit inspection time, and labor.
- What is not: the utility drop, trenching for an underground service, any rewiring inside the house, and repairs to walls the mast passes through. These are the lines that turn a $2,155 quote into a $2,694 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

$2,155 is the typical number, and three bids on the same scope normally land between $1,521 and $3,170.

Why the city changes the number
About 68% of this job is labor — $1,466 of the $2,155 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

What the quote should include
The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $2,155 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $1,521 – $3,170, that is not automatically wrong — but it is the question worth asking out loud.
