Your home’s electrical panel connects public utility electrical supply lines to your home’s electrical system, distributing power throughout your house. These panels can last for decades, but if yours is outdated or too small for the amount of power your home needs, you risk both safety and system overloads. The average cost of upgrading an electrical panel from 100 amperes to 200 amps is $1,300–$3,000. Below, we’ll explain what size panel is best for your home, how to tell when it’s time for an upgrade, and cost factors.

What Size Electrical Panel Is Best for Your Home?
The cost to upgrade your electrical panel largely depends on how much power your home uses. In a fixed 120/240-volt system, the power needed is determined by the amperage draw of the circuits in your home. Your home’s size and electrical needs—referred to as its electrical load—will determine the best amperage for your new panel. You can find online calculators to help you come up with a ballpark number, but a more specific figure will require an in-home consultation with an electrician.
Since 2015, new homes have been built with at least 200-amp service, which is the standard. If you have a small home or lack large electrical loads like HVAC systems, you can sometimes use a 100-amp panel without problems. It’s unlikely that you’ll need to upgrade to a 400-amp panel unless you have a very large home or run a home business with commercial electrical equipment.
You should recalculate your home’s electrical load if you add any of the following new appliances or renovations:
- Air conditioners
- Additional kitchen ovens
- Commercial welders, saws, or other shop tools
- Electric vehicle charger
- Finished basement or garage
- Hot tubs
- Room additions

When To Upgrade an Electrical Panel
Electrical panels can last anywhere from 25–40 years. That’s a wide range, so look out for these signs to determine when it’s time for a replacement or upgrade:
- Blinking, dimming, or flickering lights
- Frequent need to reset circuit breakers
- Buzzing, sizzling, or cracking sounds coming from outlets
- Need to stop using appliances to use others
- Damage to the panel
- Appliances running at low efficiency
- An existing panel manufactured by Federal Pacific Electric Panel or Zinsco
Factors Affecting the Cost To Upgrade an Electrical Panel
Below are the factors that determine the total cost to upgrade your electrical panel:
- Panel size: Panel size ranges from 60–400 amps. More amps cost more.
- Installation versus upgrade: It’s more expensive to install an entirely new system than to upgrade an existing panel.
- Other services: You’ll have to pay more if the panel needs relocating or your meter box needs replacing.
Cost To Upgrade Electrical Panel to a 100-Amp Service
Most residential buildings have at least a 100-amp panel, but some older homes may have circuit breaker panels as low as 60 amps. Upgrading to 100 amps is only suitable for homes that use very little electricity.
| Upgrade to 100 amps | Cost |
|---|---|
|
Panel only |
$100–$200 |
|
Panel plus installation |
$800–$1,500 |
|
New installation |
$1,200–$1,600 |
Cost To Upgrade Electrical Panel to a 200-Amp Service
Given the number of electrical devices modern homeowners need to supply power to daily, the standard panel size for modern homes is 200 amps. Most electrical panel upgrades involve replacing a 100- or 150-amp panel with a 200-amp panel.
| Upgrade to 200 amps | Cost |
|---|---|
|
Panel only |
$250–$350 |
|
Panel plus installation |
$1,300–$3,000 |
|
New installation |
$1,800–$2,500 |
Cost To Upgrade Electrical Panel to a 300-Amp Service
Upgrades to 300-amp panels are less common since homeowners who need more than 200 amps typically upgrade to 400 amps. You can still find these panels and have them installed, though.
| Upgrade to 300 amps | Cost |
|---|---|
|
Panel only |
$350–$500 |
|
Panel plus installation |
$1,800–$3,500 |
|
New installation |
$2,000–$4,500 |
Cost To Upgrade Electrical Panel to a 400-Amp Service
Only large, luxury homes need 400-amp electrical service panels. An upgrade of this size is the most costly, especially if it’s a smart panel.
| Upgrade to 400 amps | Cost |
|---|---|
|
Panel only |
$500+ |
|
Panel plus installation |
$2,000–$4,000 |
|
New installation |
$4,000–$6,000 |
Cost To Replace vs. Upgrade an Electrical Panel
Replacing an old panel with a new one of the same size versus upgrading to a larger size won’t save you much money, since roughly the same amount of labor is required to install it. You’ll save about $50–$100 on the new electrical panel itself, but pay the same amount for labor.
Cost To Install a Main Breaker
A panel’s main breaker is the master switch and overload device, controlling the flow of electricity to other circuit breakers. The cost to replace the main breaker switch itself is relatively low. If the hot bus bar, which distributes electricity from the main breaker to the others, is bad, it’s best to install a new breaker panel.
| Service | Cost |
|---|---|
|
Replace main breaker |
$200–$300 |
|
Replace the hot bus bar and main breaker |
$500–$2,000 |
Cost To Install a Subpanel
A subpanel is installed either for capacity, convenience, or cost savings. If you have little space left for more breakers, want them closer to the area where they’re used, or need to eliminate the number of wires, you can use a subpanel. Using a subpanel doesn’t increase the amount of power supplied by the main panel and often requires a main panel upgrade.
| Panel Size | Installation Cost |
|---|---|
|
50 amps |
$400–$1,000 |
|
100 amps |
$500–$1,200 |
|
150 amps |
$600–$1,750 |
Cost To Move an Electrical Panel
In some cases, upgrading may mean moving the electrical panel to fit new building codes or improving access to it. The cost of this process depends how far the panel needs to move and how much new wiring is needed.
| Service | Cost |
|---|---|
|
Low-end (e.g., moving panel 10 feet) |
$800–$1,000 |
|
High-end (e.g., extensive rewiring) |
$1,000–$3,000 |
Cost To Install an Electric Meter Box
The meter socket is an integral piece in many recent panels, but you may need a new box to house the meter in some cases. The electric meter box measures energy usage in your home. Typically the meter is removed and reset by the electric utility since it owns it, but the box installation and wiring to the main panel is done by electricians.
If you get an electrical service upgrade, you may also need a new meter box to measure the energy usage in your home. The meter box will need replacing if it’s old or damaged. Typically, this service is performed by your local electrical company instead of an electrician.
| Upgrade | Cost |
|---|---|
|
Meter box only |
$50–$250 |
|
Meter box plus installation |
$1,800–$3,500 |
Cost Factors for Electrical Panel Upgrades
On top of circuit breaker panel replacement, here are some other potential upgrades your electrical system may need:
- Replacing a fuse box with a circuit breaker box: This will cost approximately as much as installing a new electrical panel at $1,200–$4,500, depending on size.
- Replacing a circuit breaker switch or fuse: This is comparable to replacing a main breaker at $150–$250 per switch.
- Indoor versus outdoor electrical panels: Moving an indoor panel outdoors is usually labor-intensive and will usually cost $1,000–$3,000.
- Specialty breakers: Arc fault connection interrupter breakers (AFCI) cost $35–$50, and ground fault connection interrupter (GFCI) breakers cost $35–$60.
- Labor costs: Licensed electricians typically charge $50–$120 per hour.
- Permits: Your electrician will help you get a permit, which may cost $50–$300, depending on your location.
- Additional repair work: If the panel is moved or rewiring is necessary, you may have to pay for separate repair costs like new drywall, siding, and paint.

Pros and Cons of Upgrading Electrical Panels
DIY vs. Professional Electrical Panel Installation
There’s a reason electricians must be trained and licensed: Working with household electrical systems can be dangerous or create hazardous conditions. Upgrading or replacing your electrical panel isn’t a job you can do yourself. According to the National Fire Protection Association, an average of 46,700 house fires are caused by faulty electrical wiring every year. Electrical work is best performed by those who are trained in the correct electrical codes and should always be inspected.
How To Hire a Professional
Here are some tips for hiring an electrician:
- Make sure the person working on your home is currently licensed and insured.
- Check the electrician’s Better Business Bureau (BBB) page and online reviews from previous customers.
- Ask about their experience with this type of job, especially if you want an upgrade of more than 200 amps.
- Look for an electrician who offers a warranty on their work.
- Get all estimates in writing and make sure you have a signed contract before beginning.
