Electrical Subpanel Installation Cost: In 2026
Estimate electrical subpanel installation cost — with the free electrical calculator.
A subpanel brings power to a garage, workshop, basement or addition — without re-feeding the whole house. Here's the real 2026 cost.
THE SHORT ANSWER
The short answer
Electrical subpanels run $400–$2,000 installed in 2026 (typical $900–$1,500; national average ~$1,200). The panel runs $100–$500; labor and materials the rest. Permits add $100–$500. A 100-amp subpanel with full run runs $1,200–$2,000.
What it costs
A subpanel runs $400–$2,000 installed. The panel itself runs $100–$500. The feed cable, breakers and labor add the rest. A 100-amp subpanel with a long feed run runs $1,200–$2,000. Permits add $100–$500.
- Installed: $400–$2,000
- Typical: $900–$1,500
- Panel alone: $100–$500
- Permits: $100–$500
When you need one
Add a subpanel when a garage, workshop, addition or EV charger needs its own circuits — or when the main panel is full. It's cheaper than upgrading the main panel ($1,500–$3,000) and keeps new circuits local.
