Electrical Panel Upgrade Cost Calculator

Get a first-pass estimate now. If a term is unfamiliar, the quick guide below explains it before you choose.

How to use this calculator

  1. Choose the current service and target service size if you know them; if not, use the closest label on the panel door or ask an electrician.
  2. Select panel swap only when the outside service and meter are staying mostly unchanged. Use service upgrade when amperage or utility-side work changes.
  3. Treat grounding, bonding, old wiring, permits, and circuit cleanup as items that must be confirmed during inspection.

What changes the price?

  • Target amperage matters, but the bigger swing is whether the job is only a panel swap or a full service upgrade involving utility coordination.
  • Meter location, mast or underground service, grounding and bonding, circuit labeling, and old wiring conditions can expand the scope quickly.
  • Kitchens, HVAC replacements, EV chargers, additions, and insurance concerns often trigger panel work, but the right size should come from a load calculation.

Example projects

  • A 100 amp to 200 amp upgrade with minor meter coordination models a common modernization project.
  • A complex older-home service upgrade with grounding corrections and circuit cleanup models a higher-risk electrical project.

Homeowner checklist

  • Write down the existing panel amperage, target amperage, and why the upgrade is being considered.
  • Ask whether the quote includes utility coordination, permits, meter work, grounding, labeling, and circuit cleanup.
  • Treat old wiring, overloaded circuits, and service changes as inspection-driven items, not cosmetic upgrades.

Assumptions

  • Includes common panel equipment, electrician labor, standard materials, and selected service-related work.
  • Excludes whole-home rewiring, EV charger installation, generator transfer equipment, and utility fees that must be quoted separately.
  • Electrical work is safety-critical and usually permit-driven; use this only as a planning range before licensed inspection.

FAQ

Do I always need a 200 amp panel?

No. The right size depends on a load calculation, the home, and future plans such as HVAC, EV charging, or additions.

Why can panel upgrade quotes vary so much?

Two quotes may include different service, meter, grounding, circuit cleanup, permit, or utility coordination work. Compare the scope line by line.
