Cost by project size
Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| 100-amp panel | $1,800 – $6,200 |
| 150-amp panel | $2,100 – $7,300 |
| 200-amp panel | $2,400 – $8,500 |

Cost by service scenario
Panel work is not one project. Swapping a panel on an existing service is a different job from raising the service capacity with the utility involved. Every row is priced against the Annapolis median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Like-for-like panel replacement | Same amperage, existing service and meter reused | $2,100 – $3,100 |
| 100A → 150A upgrade | New panel and breakers, service conductors evaluated | $3,100 – $4,300 |
| 100A → 200A service upgrade | New panel, meter base, grounding and utility reconnect | $3,900 – $5,500 |
| 200A upgrade with mast/service entrance work | New riser or weatherhead, exterior conductors replaced | $5,100 – $7,000 |
| 400A service | Large home, dual panels or subpanel feed | $7,400 – $10,500 |
- • The utility, not the electrician, controls the disconnect and reconnect window — schedule slippage here is the usual cause of a two-day job becoming a week.
- • Meter base replacement, grounding electrode upgrades and bonding to water and gas are routinely quoted separately; ask for them line by line.
- • Federal Pacific, Zinsco and fuse panels are commonly flagged by insurers and four-point inspections, which is why many replacements are not optional.
- • Overhead-to-underground conversions add trenching and are priced by the foot.
- • If an EV charger, heat pump or solar is coming, size the service for it now — the second trip repeats the permit, the inspection and the utility coordination.
Basis: Each scope is priced as a multiple of the modeled Annapolis median for electrical panel replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
