100 Amp Panel Replacement
Quick answer
Replacing an old or failing 100-amp panel costs $1,200–$2,500 like-for-like, or step up to 200 amps for $1,500–$4,000. We'll run the load calculation and tell you honestly which your home needs.Typical installed cost: $1,200–$2,500
Not every home needs 200 amps. If your loads are modest and the panel is simply old, unsafe, or out of breaker space, a quality 100-amp replacement restores safety at lower cost, and we'll tell you plainly when the 200A step-up is the smarter money.
About 100 Amp Panel Replacement
There's an honest case for a 100-amp panel: a modest home, gas heat and cooking, no EV on the horizon, and an existing panel that's unsafe, obsolete, or out of space. Like-for-like replacement restores safety and code compliance at the lowest cost.
Where homeowners get burned is replacing at 100A and needing 200A two years later, paying for service work twice. Our assessment prices both options side by side, so the choice is informed, not accidental.
Choose 100A replacement when
- The load calculation fits comfortably within 100A
- No EV, heat pump, or major electrification planned
- The panel itself is the problem, age, damage, recalled brand, no slots
- Budget matters more than future headroom

For a smaller home with gas heat and no EV, often yes. Add an EV charger or heat pump and 100A gets tight, that's when the 200A upgrade earns its cost.
Rule of thumb: replacing a failed panel with no new loads planned → 100A is fine; any electrification plans → the incremental cost of 200A now is far cheaper than a second upgrade later.
Often only $300–$1,500 more when done at the same time, the labor overlaps heavily. That delta is why we quote both.
Yes, new AFCI/GFCI breakers, proper grounding, and a clear main disconnect. Safety isn't about amperage; capacity is.
