Electrical Upgrade Cost Estimator

1. Select the current and target service sizes. Most residential upgrades go from 100A to 200A. Homes with 60A service are increasingly rare but still exist and may need everything from the weatherhead down replaced. 400A service is for large homes or those adding significant electrical loads like EV chargers plus heat pumps.

2. Choose main panel or sub panel. A main panel upgrade replaces the primary breaker panel and usually involves the service entrance. A sub panel is an add-on panel fed from the main, typically used when you need more circuit spaces without a full service upgrade.

3. Include meter base if needed. If the meter base is undersized, damaged, or does not meet current utility specs, it needs replacement as part of the upgrade. The utility often has specific meter base requirements that vary by region.

4. Add grounding update if applicable. Older homes may have inadequate grounding electrode systems. A grounding update adds ground rods, bonding connections, and water pipe bonds to bring the system up to current code.

Service entrance scope. A simple panel swap in the same location with an adequate service entrance is the most affordable option. When the meter base, weatherhead, mast, and service entrance cable all need replacement, the job grows significantly. If the service needs to be relocated (e.g., from inside to outside), that adds more labor and material.

Current service size gap. Going from 60A to 200A is a bigger jump than 100A to 200A. The 60A upgrade usually means everything needs to be upsized — larger service entrance cable, larger conduit, new meter base, and often a new mast. A 100A to 200A often reuses more of the existing service entrance infrastructure.

Utility coordination. Every service upgrade requires coordination with the local utility. They need to disconnect and reconnect the service, which may require scheduling days in advance. Some utilities charge for this service. In some areas, you need a utility inspection before they will reconnect.

Local code requirements. Some jurisdictions require additional work during a panel upgrade — whole-house surge protection, AFCI circuits for specific areas, updated grounding systems, or smoke detector circuit upgrades. Know your local code before bidding.

Panel brand and features. Basic panels are adequate for most residential work. Smart panels with integrated monitoring, generator interlock compatibility, or built-in surge protection cost more but appeal to homeowners interested in energy management and backup power readiness.

Quick phone estimates. Panel upgrades are one of the most commonly requested electrical services. When a homeowner calls, ask about their current service size and what is driving the upgrade. Plug it in and give them a range on the spot. Fast quoting wins jobs.

EV charger and heat pump add-ons. Many panel upgrades are driven by the need for a Level 2 EV charger or a heat pump installation. When another contractor tells the homeowner they need a panel upgrade first, being able to quote it quickly makes you the go-to electrician for the follow-up work.

Real estate and inspection situations. Home inspectors frequently flag outdated panels, recalled brands, or undersized services. Buyers need a fast quote to factor into their purchase decision. Having a reliable estimating tool lets you respond same-day.
