What drives the price
- Service sizeMoving from 100 to 200 amps is the most common upgrade and often needs a new meter base and service cable.
- Utility workThe power company usually has to disconnect and reconnect service, which affects scheduling.
- Code updatesA new panel often triggers grounding, bonding and breaker updates.
- Why you're upgradingEV chargers, heat pumps and home additions are the usual reasons homes run out of capacity.
How this estimate works
The calculator starts from the installed price range for the type you pick, then adds any extras you tick and typical permit and inspection. The headline number is the midpoint of your range. Low-end prices fit simple jobs in lower-cost areas. High-end prices fit complex jobs, premium brands and high-cost metros.
Get at least three written quotes before you hire. Ask each contractor to list materials, labor, permits and disposal separately so you can compare them line by line. Read how we build our ranges.
Common questions
How long does a panel upgrade take?
The work itself often takes a day, but permits and utility scheduling can stretch the timeline.
Do I need 200 amps?
Many modern homes with electric heating, EV charging or large appliances need 200 amps. An electrician can do a load calculation.
Can I upgrade my panel myself?
Panel work requires a licensed electrician and a permit in most areas, and the utility must be involved.
