Notes

Where the number comes from. The national price for a 400-amp service upgrade is $6,000 installed — service panel upgrade pricing published for 2026. Labor is about 68% of that. Electricians near Oklahoma City, OK average $62,550 a year against a U.S. mean of $71,490 — a factor of 0.875 — 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 $5,490 quote into a $6,862 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.

a 400-amp service upgrade in Oklahoma City, OK

$5,490 is the typical number, and three bids on the same scope normally land between $3,660 and $8,235.

That is $510 less than the same job priced at the national average.

Why the city changes the number

About 68% of this job is labor — $3,733 of the $5,490 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 $5,490 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 $3,660 – $8,235, that is not automatically wrong — but it is the question worth asking out loud.
