Replacing your electrical panel is a significant upgrade for your home, but it’s not something that comes cheap. The cost to replace electrical panel can range from $1,500 to $12,800 or more, depending on various factors. On average, homeowners can expect to pay around $5,000 for a panel replacement. However, several factors influence this price, making a simple replacement more complex and costly than expected.
What is an Electrical Panel?
An electrical panel (also known as a breaker box or service panel) is the central hub that distributes electrical power throughout your home. It connects your home’s electrical system to the utility grid, housing circuit breakers or fuses that protect your home from electrical overloads. If your current panel can’t handle the electrical load, it’s time to upgrade or repair it.
Factors That Influence the Cost of Replacing an Electrical Panel
1. Amperage Upgrade
Upgrading your panel is typically the primary factor affecting the cost.
- 100-amp to 200-amp: Costs between $1,400 and $4,500 for homes with newer electrical appliances or central air conditioning.
- 200-amp to 400-amp: Costs can go up to $5,125 to $12,800 for larger systems or homes with higher energy demands.
2. Rewiring
Older wiring may not support the increased power load from a newer, larger electrical panel. Rewiring your home can cost between $3,850 and $10,300.
3. Panel Accessibility
If your electrical panel is in a difficult-to-reach location (behind finished walls or in crawl spaces), the labor costs will increase by $500 to $2,000.
4. Permits and Inspections
Electrical panel replacements require permits to ensure that the work meets local safety codes. Permits typically cost between $200 and $500.
5. Additional Circuits and Upgrades
If you’re adding new circuits for modern appliances or a home addition, expect to budget $100 to $250 per circuit. Upgrading your grounding system may add between $200 and $500 to the total cost.
Signs of a Dangerous or Damaged Electrical Panel

If you notice any of these signs, it’s time to consult a licensed electrician:
- Burning Smells or Discoloration: A burning smell or visible burn marks on the panel or nearby outlets.
- Overheating: The panel feels warm or hot to the touch.
- Visible Damage: Rust, corrosion, or other physical damage to the panel or wiring.
- Old or Unsafe Brands: Panels from faulty manufacturers like Federal Pacific Electric or Zinsco.
- Fuse Boxes: If your home still uses a fuse box, upgrading to a modern circuit breaker panel is a safety recommendation.
Signs Your Electrical Panel Can’t Meet Your Needs
If your home experiences any of the following issues, it might be time to upgrade:
- Frequent Breaker Trips: If circuit breakers trip often, the system is likely overloaded.
- Dimming or Flickering Lights: Lights dim or flicker when appliances turn on.
- Intermittent Power: Appliances or lights turn off unexpectedly.
- Inability to Power Appliances: Your electrical system can’t support multiple heavy appliances simultaneously.
When Should You Upgrade Your Electrical Panel?
Consider upgrading your electrical panel if you’re planning any of the following:
- Home Renovations: Expanding your home or adding new circuits requires a panel that can handle the increased electrical load.
- New, High-Demand Appliances: Installing appliances like hot tubs, electric vehicle chargers, or large HVAC systems will require an upgraded panel.
- Using Too Many Extension Cords: If you rely on multiple extension cords, it may indicate the need for more outlets, which typically requires a panel upgrade.
Cost Breakdown (Estimates)
- Panel Replacement/Upgrade (100-amp to 200-amp): $1,400 – $4,500
- Rewiring: $3,850 – $10,300
