Electrical Panel Upgrade Cost Calculator

Upgrade if any of these apply: existing panel is 100A or less and you plan to add EV charger / heat pump / induction range / solar / hot tub; fuse-box panels (vs breakers); Federal Pacific, Zinsco, or Pushmatic brands (insurance/lender flags); panel is at 80%+ continuous load per NEC 220.83 calc; physical signs (corrosion, double-tapped breakers, melted insulation). 200A is standard for new construction since the 1990s.

Total $1,800-$4,500 typical, breaking down as: panel itself $300-$700, service entrance cable upgrade $500-$1,500 (often required at this amperage jump), meter base + mast $200-$600, permit + inspection $150-$500, electrician labor (8-12 hours) $1,000-$2,000. High-cost states (CA, NY, MA) add 25-40%. Federal Section 25C tax credit: 30% of cost up to $600 for electrification-enabling panel upgrades.

Almost never for residential. 200A handles: 2 EV chargers + heat pump + induction range + electric water heater + electric dryer + AC + general loads, even at simultaneous peak demand, per NEC load calc. 400A makes sense only for: 5,000+ sq ft luxury homes, attached commercial uses (workshop, kiln, dental office), or homes with hot tub + pool heat + 3+ EVs. 400A panel upgrades run $4,000-$8,000+ vs $2,000-$4,500 for 200A.

4-6 hours of electrician labor for a like-location upgrade. Power must be cut at the utility meter while old panel is removed and new one wired - typical outage 2-4 hours. Schedule a utility meter pull and re-set in advance. Permit + inspection usually pulled before work begins; final inspection same-day or next-day. Some utilities require their own meter inspection before re-energizing.
