How We Calculate

We combine national panel and labor cost data with your specific inputs (current amperage, target amperage, rewiring needs) to generate a realistic range, not a false single number.

Key Assumptions

Estimates assume a standard residential panel upgrade with reasonable electrical panel access unless otherwise selected.

Accuracy & Limitations

Estimates are for planning purposes only and may vary based on your home's existing wiring, local code requirements and utility coordination fees. Always get multiple local quotes.

Frequently Asked Questions

How do I know if I need a panel upgrade?

Common signs include frequently tripped breakers, a panel with fuses instead of breakers, or adding major appliances/EV chargers that exceed your current capacity.

Is 200 amp enough for a modern home?

200 amps is the standard for most modern homes, though larger homes with EV charging, pools or extensive electronics may benefit from 400 amp service.

Do I need a permit and inspection for a panel upgrade?

Yes, panel upgrades almost always require a permit and utility coordination since they involve your main electrical service.

Why would rewiring be needed?

Homes with old, damaged, or unsafe wiring (such as knob-and-tube or aluminum branch wiring) may need partial or full rewiring alongside a panel upgrade.
