A real price range for a panel upgrade, EV charger, rewire, generator, or repair in about 30 seconds. Built for electricians, free for homeowners.
Updated August 2026
This electrical calculator asks a homeowner what they need, an outlet, a fixture, a panel upgrade, an EV charger, a rewire, a generator, a repair, then prices it as a real low-to-high range. For the bigger jobs it asks one follow-up, a 100 or 200 amp panel, an EV charger with or without panel work, a partial or whole-home rewire, a portable or standby generator, and narrows the number. The homeowner sees a price on screen with no email required.
It is also a free calculator any electrical company can put directly on their own site. Set it up below and every homeowner who runs it on your site becomes a lead in your inbox, full breakdown included.
It captures homeowner leads for you, full name, contact info, and the estimate they got, emailed to you the second someone submits it. Takes one block of code and stays free forever.
A homeowner prices a 200 amp panel upgrade on a Sunday after the breakers tripped again, likes the number, and taps Book this visit. They pick a slot and it is on your calendar before Monday, while the call would still be sitting in your voicemail.

Adding an outlet, upgrading a panel, and rewiring a house are three different amounts of work, so the calculator prices from the type of work first. For an everyday job that is enough to give a real range. For a bigger job the price swings on one more answer.
A panel is not one price, it is a 100 amp price and a 200 amp price, with a service relocate higher still. An EV charger is cheap when the panel has room and a lot more when it does not. A rewire is a handful of circuits or the whole house. A generator is a portable unit you start by hand or a standby unit that starts itself. That is why the calculator asks a single follow-up on those jobs, so the number lands near the real work instead of a wide guess. What it cannot see, the full panel, the out-of-date grounding, the permit your city requires, is measured on the visit and is what turns the range into a firm quote.
This table pairs each job the calculator prices with a national ballpark range and the one thing that moves it most. The ranges are wide on purpose, because panel condition, local rates, and the run all move them hard. Use it as a sanity check, then run the real job through the calculator above.
| Job | Ballpark range | What moves it |
|---|---|---|
| Outlet or switch | $150 to $400 | New run vs a same-box swap |
| Light fixture or ceiling fan | $150 to $500 | Existing box vs new wiring and bracing |
| Troubleshooting or repair | $125 to $350 | How long the fault takes to trace |
| Panel upgrade, 100 amp | $1,200 to $2,500 | Meter and grounding condition |
| Panel upgrade, 200 amp | $1,800 to $4,500 | Service size and utility coordination |
| Service relocate | $3,000 to $8,000 | New mast, trenching, and permit |
| EV charger, level 2 | $500 to $1,500 | Run length from the panel to the garage |
| EV charger with panel work | $1,500 to $4,000 | A full or undersized panel needs a circuit added |
| Rewire, partial | $2,000 to $8,000 | How many circuits and how open the walls are |
| Rewire, whole home | $8,000 to $25,000 | Square footage and knob-and-tube removal |
| Generator, portable with inlet | $600 to $1,800 | Inlet box and interlock kit |
| Generator, standby | $6,000 to $15,000 | Unit size, gas line, and transfer switch |
Everyday devices and repairs cluster in the low hundreds; the spread opens up on panels, rewires, and standby generators, where the type of job matters more than any single part. That spread is exactly what the follow-up questions in the calculator are there to narrow.
Most electrical calls price cleanly off the task. A few do not, because a single label hides two or three very different amounts of work. The calculator prices these by type so a homeowner is not handed a range wide enough to be useless.
A 100 amp panel covers a smaller home; a 200 amp service is the modern standard once there is central air, an EV, or an electric range. Moving the service to a new spot adds a mast, trenching, and utility coordination, which is why it prices higher.
When the panel has an open slot and the garage is close, a level 2 charger is a quick job. When the panel is full or undersized, it needs a new circuit, a subpanel, or a service upgrade, and the price climbs to match.
Replacing a few problem circuits is a different job from pulling new wire through the whole house and tearing out knob-and-tube. How many circuits and how open the walls are set the number.
A portable unit with an inlet and interlock is the budget path you start by hand. A standby unit is permanently installed, runs on gas, and starts itself through an automatic transfer switch, so it costs more to install and less to think about.
Here is the full chain from a homeowner's problem to a real number, the same steps the calculator above runs the instant they answer.
The homeowner picks "EV charger." A new car is arriving and the garage has no 240 volt outlet.
The calculator asks whether the panel has room. The homeowner's panel is a full 100 amp, so they pick "needs panel work."
A level 2 charger with panel work prices near $1,500 to $4,000 on national defaults, or on the electrician's own numbers when they set them.
The homeowner marks it planning, not an emergency, which tells the electrician it can be a scheduled visit rather than a same-day call.
If they choose to send it, the electrician gets the job, the range, the urgency, and the homeowner's contact, emailed the second they submit.
The panel's real capacity, the run to the garage, and the permit are measured on the visit and adjust the final quote from this ballpark.
Two homes can get quotes hundreds or thousands of dollars apart for the same job, and none of it is padding. These are the things a site visit measures that a quick estimate cannot see.
The panel is the biggest one: an open slot and modern grounding make a circuit quick, while a full or out-of-date panel turns the same job into a service upgrade. After that come the length and path of the wire run, whether it crosses a finished wall or floor; the condition of the existing wiring, since old knob-and-tube or aluminum may have to be replaced rather than reused; the permit and inspection fee, which varies by city; the utility's role on a meter or service change; and any grounding or bonding the inspector brings up to current code. An emergency or after-hours call adds a premium on top. That is why the calculator gives a range and the on-site visit gives the firm number.

What comes up before installing the calculator, pricing a repair, or quoting a bigger job.
Yes. There is no subscription, no trial period, and no card required, for the electrician installing it or the homeowner using it. Homeowners see a real price range with no email required to see a number, and electrical companies who install it on their own site keep it free forever.
No. Enter your business name and email once to get your embed code, hosted link, and QR code, that is the whole setup. There is no dashboard to log into and no account to manage.
Every submission is emailed to you instantly, with the homeowner's name, contact info, the job they picked, and the price range their answers produced. Lead emails start once you click the one-time confirmation link we send when you set up your embed. The calculator still works for homeowners before that, it just is not emailing you yet.
Yes. Set a low-to-high range for the everyday jobs like outlets, fixtures, and troubleshooting, and a range for each type of the bigger jobs, a 100 or 200 amp panel, a level 2 EV charger with or without panel work, a partial or whole-home rewire, a portable or standby generator. Every estimate your calculator gives then runs on your numbers. Leave any of them blank and that job falls back to a solid national default.
The credit line is what keeps the calculator free. Keep it in place and the calculator, the leads, and the emails stay free forever.
Most residential electricians bill somewhere between $75 and $200 an hour, with the higher end in big metros and for a licensed master electrician. Many shops price by the job rather than the hour using a flat-rate book, so a homeowner sees one number for the task instead of a running clock. A service call often carries a trip or diagnostic fee, and emergency or after-hours work adds a premium. This calculator prices by the job, which is how most homeowners actually get quoted.
It depends on the electrical load of the home. A 100 amp service covers a smaller home with gas heat and cooking and no big electric loads. A 200 amp service is the modern standard and is what most homes need once you add central air, an electric range or dryer, a hot tub, or an EV charger. If breakers trip under normal use, the panel is full with no open slots, or you are planning any of those additions, a 200 amp upgrade is usually the right call. The calculator prices both so the homeowner sees the gap.
A level 2 home charger commonly runs $500 to $1,500 installed when the panel has room and the run to the garage is short. It climbs to roughly $1,500 to $4,000 when the panel is full and needs a new circuit or a subpanel, when the run is long, or when the panel itself has to be upgraded to carry the load. The charger hardware, the wire run, the breaker, and any panel work are what move the number, which is why the calculator asks whether panel work is needed.
Most homes do not, but some do. Knob-and-tube or cloth-wrapped wiring, aluminum branch wiring, two-prong ungrounded outlets throughout, breakers that trip for no clear reason, or scorch marks at outlets are the signs that point to a rewire. A partial rewire replaces the problem circuits; a whole-home rewire replaces everything and is usually done when the walls are already open or the wiring is a safety issue across the house. The calculator prices a partial and a whole-home rewire separately because they are far apart.
It comes down to how much you want automated. A portable generator with an inlet box and an interlock kit is the budget path: you roll it out, plug it in, and start it by hand when the power goes, commonly $600 to $1,800 for the electrical work. A standby generator is permanently installed, runs on natural gas or propane, and starts itself within seconds of an outage through an automatic transfer switch, commonly $6,000 to $15,000 installed depending on the unit size and gas line. The calculator prices both paths.
Often yes. Most jurisdictions require a permit and an inspection for panel upgrades, service changes, new circuits, EV chargers, generators, and any rewire. A like-for-like device swap such as replacing a single outlet or switch usually does not. Permit and inspection costs vary by city and are part of the quote a licensed electrician gives, which is one reason the on-site number can sit above a rough estimate. The calculator's ranges assume permitted work where a permit applies.
The condition behind the wall moves an electrical price more than the fixture does. Adding a circuit is quick when the panel has an open slot and the run is short; the same job turns into a bigger one when the panel is full, the grounding is out of date, or the wire has to cross a finished floor. The age of the service, the utility's role in a meter change, local permit costs, and whether old wiring is safe to reuse all shift the total. That is why the calculator gives a range and treats the on-site visit as the exact figure.
A complete estimate covers the labor, the devices and materials, the breaker and wire, any permit and inspection fee, and cleanup. For a bigger job it also accounts for the panel or service work the load requires, any grounding or bonding brought up to current code, patching where a wall had to be opened, and utility coordination on a meter or service change. The by-type pricing in the calculator shows how the scope behind the wall, not just the device on it, moves the number.
Treat it as a solid ballpark that gets a homeowner oriented before anyone visits. It prices the job from the type of work and a few follow-up answers, on regional defaults or the electrician's own numbers. An in-home visit opens the panel, checks the grounding and the existing wiring, and accounts for the run and local permit costs, which is what turns the ballpark into a firm price. The calculator's job is to give a real number fast and start the conversation, not to replace the site visit.
No. The calculator shows a real price range on screen from the homeowner's answers before it asks for anything. Contact details are only requested if the homeowner wants that estimate sent to an electrician or wants a call back. That is deliberate, a tool that shows a number first earns more finished submissions than one that gates the result behind a form.
