When do I need to upgrade to a 200-amp panel?
Upgrade to 200A when: you're adding an EV charger, heat pump, or induction range; your breaker space is full; your existing panel is 100A or smaller; or your panel brand is Federal Pacific or Zinsco regardless of amperage.

A 200A service is the modern standard for almost all single-family homes built in the last 25 years because it provides headroom for the loads homes now actually carry: HVAC, EV charging, induction cooking, heat pumps, whole-home batteries, hot tubs, and workshop tools.
You should upgrade if your panel is 60A or 100A (common in homes built before 1985), if you have no physical breaker space left and keep adding tandems, if you have a Federal Pacific or Zinsco panel (safety issue), or if you're planning to add an EV charger, heat pump, or induction range and the load calculation says you're past capacity.
A 200A upgrade is typically a 1-day job with permit and inspection.
