Cost is one of the first questions homeowners ask about a main service panel upgrade. In the USA, you can expect a wide range depending on amperage, location, and the condition of your existing electrical system. Here is a transparent breakdown.
Typical Cost Ranges:
- 100‑amp to 100‑amp replacement: $1,200–$2,500. You’re replacing an old or unsafe panel with a new one of the same capacity.
- 100‑amp to 200‑amp upgrade: $1,800–$4,000. This is the most common upgrade in American homes and includes new service entrance cable, meter socket, and panel.
- 200‑amp to 400‑amp upgrade: $3,500–$7,000+. Required for very large homes, multiple EV chargers, or heavy solar installations.
What Drives the Cost? Labor is the biggest factor, followed by materials. A 200‑amp panel itself costs $200–$600, but the electrician’s time, permit fees, and utility coordination make up the rest. Additional work—like repairing damaged wiring, relocating the panel, or upgrading the grounding system—adds cost. A panel located in a finished wall or hard‑to‑access space also increases labor.
Hidden Costs to Plan For: Permits typically run $100–$300. Some utilities charge a disconnect/reconnect fee. If your home needs a new meter socket or service mast, add $500–$1,500. If drywall repair is needed after the electrician cuts access, budget another $200–$800.
Is It Worth It? A panel upgrade is one of the highest‑ROI electrical improvements you can make. It increases safety, enables modern appliances, and can add resale value. Some upgrades also qualify for incentives—see our article on panel upgrade insurance and incentives.
