Panel Upgrade Cost Estimator
Estimate the total cost of upgrading your home's electrical panel based on amperage size, region, permit requirements, and additional complexity factors.
Current Panel Amperage
60A (older home) 100A (standard) 150A (mid-size) 200A (modern)
Upgrade To (New Amperage)
100A 150A 200A 400A (large home / EV)
Region / Cost of Living
Rural / Low Cost Suburban / Average Urban / High Cost Major Metro (NYC, SF, etc.)
Permit Required?
Yes No
Meter Socket Upgrade Needed?
No Yes
Grounding / Bonding Update Needed?
No Yes
Number of Circuits to Reconnect
Service Entrance Cable Replacement?
No Yes

#### Formula
Total Cost = (Base Panel Cost + Circuit Cost + Add-on Costs) × Regional Multiplier
- Base Panel Cost: 100A → $850 | 150A → $1,100 | 200A → $1,500 | 400A → $2,800 (includes panel unit + standard labor)
- Circuit Reconnection Cost = Number of Circuits × $20/circuit
- Permit Fee: $250 (if required)
- Meter Socket Upgrade: $400 (if needed)
- Grounding / Bonding Update: $350 (if needed)
- Service Entrance Cable Replacement: $800 (if needed)
- Regional Multiplier: Rural 0.80× | Suburban 1.00× | Urban 1.30× | Major Metro 1.60×
- Estimate Range: ±15% around the central estimate
