(Panel base + Scope adder), adjusted by Region = Total
The estimate takes the 2026 installed base — $1,600 for 100A, $2,500 for 200A, $4,500 for 400A — adds the scope adder ($0, $800, or $1,800), then applies the region multiplier. The total splits into the panel, breakers, and materials (about 40%) and licensed labor (about 60%: permit, utility coordination, installation, inspection).
Materials ≈ 40% · Labor ≈ 60%
About 40% of the project is materials (the panel, breakers, and wire); the other 60% is labor (the electrician, permits, and inspection).
The low–high range reflects the published band for a standard panel swap.
