At home, Tesla charging costs the amount of electricity used multiplied by the rate your utility charges when the car is charging. As a U.S. illustration, 50 kWh at the U.S. Energy Information Administration’s 2025 residential average of 17.30 cents per kWh comes to $8.65. Your bill will differ with your electricity tariff, charging energy and any charging losses.
How to calculate your home charging cost
Use the energy used for charging, in kilowatt-hours (kWh), and the electricity price that applies at that time:

Charging cost = charging energy (kWh) × electricity rate ($/kWh)
For example, 50 kWh × $0.173 per kWh = $8.65. This is the cost of 50 kWh at that rate—not a claim that every charging session adds 50 kWh to the battery or draws exactly 50 kWh from the meter. Charging losses and the energy actually recorded affect the result.

The EIA reports a 2025 annual average U.S. residential retail electricity price of 17.30 cents per kWh. It identifies the figure as preliminary and cites Electric Power Monthly Table 5.3, February 2026. It is a national comparison point, not a quote for your home; electricity prices vary by locality. See the EIA’s residential electricity price data.
Estimate a session, monthly bill, or cost per mile
One charging session
Multiply the charging energy for the session by the rate that applied while charging. Tesla Charge Stats can show charging energy in kWh and an estimated cost by location. For a useful estimate, compare the vehicle’s recorded energy with your actual utility tariff.
A month of home charging
Multiply total home-charging kWh for the month by the applicable rate. If your utility has time-of-use pricing, calculate energy charged in each rate period separately and add the costs. For example, overnight charging may have a different price from daytime charging; the plan determines whether the overnight period is cheaper.

Engineered for Tesla-style charging standards, it ensures reliable daily home charging performance. Note: For J1772-equipped EVs, a compatible J1772 adapter is required (adapter not included)
Cost per mile
To estimate what home charging costs for your driving, use the Tesla’s actual or otherwise reliable energy consumption for your model and trim, convert it to kWh per mile, and multiply by your rate. Miles driven alone are not enough: consumption changes with model, trim and driving conditions, and a battery’s nominal capacity is not the same as the energy drawn from the wall.
Use your own utility rate, not a national average
Your rate is the key input. Check your current utility bill or tariff for the price that applies to EV charging, including applicable delivery charges and time-of-use periods. The EIA’s 17.30-cent 2025 average is useful for context, but it does not establish what a particular household pays.
Tesla’s calculator displays a residential electricity assumption of $0.14 per kWh. That is a calculator input, not a current rate quote for your address. For your estimate, use your own tariff; for a dated national comparison, the EIA reports its preliminary 2025 average. View Tesla’s charging-cost calculator.

Check Tesla Charge Stats against your bill
Tesla Charge Stats lets owners configure a home electricity rate by selecting a listed utility plan or entering a custom plan, including time-of-use and seasonal periods. The displayed cost is an estimate based on the rate configured there, so check that it matches the tariff on your bill and the periods when the car charges.

- Set the home rate using a listed utility plan or enter the applicable custom rate, including time-of-use or seasonal periods if relevant.
- Compare the configured rate with your current utility bill or tariff, including applicable delivery charges.
- When optimizing spending, schedule charging during a lower-priced period if your utility plan actually offers one. See Tesla’s Charge Stats guidance.
Tesla recommends prioritizing off-peak charging to manage spending, but savings depend on the customer’s actual tariff and whether charging can take place during the discounted period.

A charger or outlet setup affects one-time equipment, installation, convenience and charging speed. It does not change the electricity cost for a given amount of energy at a given rate. Tesla’s U.S. home-charging page, observed October 4, 2026, lists these purchase prices and estimated installation ranges; prices and estimates can change.

| Home charging option | Tesla-listed equipment price | Tesla estimated installation range | What to know |
|---|---|---|---|
| Mobile Connector | $300 | $0–$1,500 | Portable; can be used with supported household outlets and compatible 240 V outlets, subject to suitability and installer approval. |
| Wall Connector | $585 | $750–$1,500 | Fixed home unit; Tesla describes it as an optimal fast-charging option. |
| Universal Wall Connector | $660 | $750–$1,500 | Tesla says it supports NACS and J1772. |
These are Tesla listings and estimates, not an installed-price guarantee. Site conditions and electrical work can affect installation cost. Tesla identifies possible extra work such as a long wire run, an additional electrical panel, trenching, a main-panel upgrade, pedestal installation or cable concealment; seek a site-specific quote from a certified installer. See Tesla’s home-charging equipment and support information.
Do you need a Wall Connector?
No. Tesla says a Wall Connector is not required for home charging. A Mobile Connector may work with a standard 120 V household outlet or a suitable, approved 240 V outlet and compatible adapter. Confirm that the vehicle, outlet, adapter and circuit are compatible and suitable with Tesla and a qualified installer.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsTesla’s support page says a Mobile Connector on a standard 120 V outlet may provide 2–3 miles of charge per hour; with an approved 240 V outlet and suitable adapter, it may provide up to 30 miles per hour. Tesla says the Mobile Connector and Wall Connector offer the same maximum 32 A, up-to-30-miles-per-hour rate for Model 3 Rear-Wheel Drive and Model Y Rear-Wheel Drive. These are Tesla charging-speed claims, not a reduction in the kWh needed for the same driving.
What determines whether home charging is cheaper?
- Your electricity tariff: the price per kWh, including applicable delivery charges and time-of-use periods, determines the energy cost.
- Energy used: charging kWh depends on how much energy the car needs, not merely the charger’s advertised speed.
- Charging schedule: an off-peak period can lower the cost only if your plan has a lower rate then and charging occurs during that period.
- Setup costs: equipment, installation and any electrical upgrades are separate one-time costs, not part of the recurring electricity calculation.
Tesla says home charging is often the cheapest option, and that savings may increase with an EV time-of-use plan where available. Your own comparison depends on your rates and charging circumstances.
