Electrical Panel Replacement Cost Calculator
Aging electrical panels create safety + capacity concerns — plan replacement.
Total project cost
$58,200
Direct cost
$47,800
Shutdown cost
$10,400
How the math works
Direct = equipment + (hours × rate). Total = direct + (shutdown loss × hours).
$28k + 120 × $165 = $47.8k + 16 × $650 = $58.2k total.
How to Use
- Enter panel amperage.
- Enter equipment cost.
- Enter labor hours.
- Enter labor $/hour.
- Enter shutdown loss / hour.
- Enter shutdown hours.
- Read total project cost.
Frequently Asked Questions
Replacement triggers?
Federal Pacific Electric (FPE) Stab-Lok panels: known fire hazard. Replace immediately. Zinsco panels: similar concerns. Aluminum branch wiring: requires specialized terminations. Bus bar damage: scoring, melting indicates immediate replacement. Insurance non-renewal: many insurers exclude FPE/Zinsco coverage. Code upgrade triggered by major renovation.
Cost ranges?
200A residential service: $2-6k. 400A: $4-12k. 800A commercial: $15-50k. 1200A switchboard: $50-150k. 2000A+ commercial main: $100-500k. Multi-meter MRH: $25-200k depending on configuration. New service drop from utility: $5-50k pole work + $5-25k underground. Panel replacement cost dominated by labor + permitting on smaller jobs.
Shutdown cost?
Commercial property: $200-2,000/hour lost revenue/operations. Multi-day shutdown: $5,000-50,000+ depending on tenant impact. Mitigation: temporary generator + bypass: $5-25k. Phased switching (split into two service drops): allows partial operations. Best practice: schedule for low-occupancy weekend with detailed coordination.
Capacity upgrade?
Replace + upgrade: most cost-effective when panel needs replacement anyway. 200A → 400A: $5-15k incremental. 400A → 800A: $15-50k incremental. Triggered by EV charging, solar, heat pump electrification. Plan capacity for 10-20 year horizon, not just current load. Service drop upgrade: utility coordination 6-18 months.
