Estimate electric panel upgrade cost from panel or service size in amps or kiloamps, or find the service size implied by a budget.

undefined

Budgeting model: $2,500 per 200 A by default. Real quotes vary. Budget-derived amperage is a model equivalent; an electrician must size the service from its load.

Electric Panel Cost Formula

The calculator uses a simple proportional estimate based on a reference cost of $2,500 for a 200-amp electric panel or service upgrade.

Cost = (A / 200) × 2500
A = (Cost / 2500) × 200
A = kA × 1000
  • Cost = estimated electric panel upgrade cost in dollars
  • A = panel or service size in amps
  • kA = panel or service size in kiloamps
  • 200 = reference service size in amps
  • 2500 = reference installed cost in dollars

Choose estimated upgrade cost to scale a panel or service size, or budget-equivalent amperage to invert the same model. Kiloamps are converted to amps. The default reference is $2,500 for 200 A; an optional reference estimate can be changed. The inverse result is not a service-sizing recommendation.

Common Electric Panel Upgrade Cost Estimates

These values follow the same proportional assumption used by the calculator. Actual installed prices can be higher or lower depending on labor, permits, utility work, panel location, and local code requirements.

Panel or Service Size Estimated Cost Typical Use
100 A $1,250 Smaller or older homes with modest electrical demand
150 A $1,875 Mid-size homes or partial upgrades
200 A $2,500 Common modern residential service size
300 A $3,750 Larger homes or higher electrical loads
400 A $5,000 Large homes, workshops, or heavy electrical equipment

Amps and Kiloamps Conversion

Unit Conversion Example
Amps A = A 200 A = 200 A
Kiloamps A = kA × 1000 0.2 kA = 200 A

Example Problems

Example 1: Estimate the cost for a 200-amp panel

Choose estimated upgrade cost and enter 200 A, using the default reference estimate.

Cost = (200 / 200) × 2500 = 2500

The estimated electric panel upgrade cost is $2,500.

Example 2: Estimate the service size from a $3,750 budget

Choose budget-equivalent amperage and enter a $3,750 budget, using the default reference estimate.

A = (3750 / 2500) × 200 = 300

The estimated panel or service size is 300 A.

FAQ

Is this the actual cost to upgrade an electric panel?

No. This is a rough budgeting estimate. Real electric panel upgrade costs depend on electrician labor rates, permit fees, utility requirements, grounding work, meter work, panel brand, service entrance condition, and how much wiring must be changed.

Why does the cost scale directly with amps?

The calculator uses a simple linear estimate, meaning a larger service size produces a proportionally larger cost. This is useful for quick planning, but real project pricing is not always linear. For example, moving from 100 A to 200 A may require more utility or service equipment work than a simple panel replacement.

What size electric panel do you need?

The right panel size depends on your home’s electrical load. Major loads include heating and cooling equipment, electric water heaters, EV chargers, ranges, dryers, workshops, and future additions. For an actual upgrade, a licensed electrician usually performs a load calculation before recommending a service size.
