How Much Does It Cost to Replace a Breaker Box?
Replacing a breaker box (electrical panel) typically costs $1,300 to $4,000, with most homeowners around $1,500–$2,500. A like-for-like swap sits at the low end; upgrading amperage, moving the panel, or updating old wiring pushes it higher. A 400-amp service can reach $12,000.
Your breaker box distributes power throughout your home. When it's outdated, unsafe, or full, replacing it restores capacity and safety. Here's what it costs and the signs you're due.

Signs You Need a New Breaker Box
- You still have a fuse box or an old, obsolete panel
- Breakers trip frequently or the panel is full
- The panel is warm, buzzing, rusted, or smells burnt
- You're adding major loads (EV charger, AC, addition)
- Your panel is a brand with known safety recalls
Why it matters: an outdated or overloaded panel is a real fire hazard. Replacing it improves safety, adds capacity for modern demand, and is often required before other upgrades can be done.
