About this calculator
Upgrading an electrical panel — say from an outdated 100-amp fuse box to a modern 200-amp breaker panel — is priced around the new panel's amperage capacity, whether the service entrance wire and meter also need upgrading to handle the higher capacity, and permit/inspection fees required by virtually every jurisdiction for panel work. This calculator prices the job as a base panel-and-labor cost that scales with target amperage, an optional service entrance upgrade (needed when jumping amperage significantly, like 60-amp to 200-amp), and a flat permit allowance. 2026 US national averages run about $1,800-$3,200 for a straightforward 200-amp panel upgrade with no service entrance changes, and $3,000-$4,500+ when the meter base, weatherhead, and service entrance cable also need replacing to support the new capacity. Homes needing a full panel relocation (moving it to a new wall or location) or a utility company service upgrade coordination typically run higher still — those variables aren't captured in a simple calculator and need a licensed electrician's on-site assessment.
Worked example
Using the values the calculator loads with:
Inputs
- Target panel amperage: 200 amp — ~$2,200 base
- Service entrance / meter upgrade needed?: No — existing service is adequate
- Service entrance upgrade cost: 1200 $
- Permit & inspection fee: 200 $
Results
- Total panel upgrade cost: $2,400
- Panel + labor cost: $2,200
- Service entrance upgrade: $0
- Permit & inspection fee: $200
What each field means
Inputs
- Target panel amperage
- Pick the option that matches your situation — the maths changes per option. Choices: 100 amp — ~$1,600 base, 200 amp — ~$2,200 base, 400 amp — ~$3,200 base.
- Service entrance / meter upgrade needed?
- Pick the option that matches your situation — the maths changes per option. Choices: No — existing service is adequate, Yes — needs upgrading.
- Service entrance upgrade cost ($)
- The service entrance upgrade cost used in the calculation, measured in $. Starts at 1200 $ so you have a working example on load. Accepted range: 400–3000 $.
- Permit & inspection fee ($)
- The permit & inspection fee used in the calculation, measured in $. Starts at 200 $ so you have a working example on load. Accepted range: 50–600 $.

FAQ
Do I need a 200-amp panel for my home?
Most modern homes with central AC, an electric range, and EV charging or planned solar benefit from 200 amps; smaller homes without those loads can often stay on 100-150 amps. An electrician can calculate your actual load requirement rather than guessing based on panel age alone.
Why does the service entrance sometimes need upgrading too?
The panel is only as capable as the wire and meter feeding it — jumping from a 60-100 amp panel to 200 amps often requires larger service entrance cable, a new meter base rated for the higher amperage, and sometimes utility company coordination to upsize the transformer tap, all of which add cost beyond just the panel itself.
How long does a panel upgrade take?
A straightforward swap with no service entrance changes typically takes a full day, but expect a power outage of several hours during the swap, and the work must pass a municipal electrical inspection before the utility will re-energize service in some jurisdictions.
Does homeowners insurance care about panel type?
Yes — many insurers charge higher premiums or refuse coverage for homes with outdated fuse boxes or certain flagged panel brands (like some older Federal Pacific or Zinsco panels) due to documented fire risk, so an upgrade can sometimes lower insurance costs enough to offset part of the project cost over time.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
