Tesla charging calculator
Charging a Tesla at home from 10 to 80 percent takes about 5.4 to 8.5 hours on a 48 amp Wall Connector, 6.3 to 12.7 hours on a 32 amp Mobile Connector plugged into a NEMA 14-50 outlet, and 33.6 to 67.8 hours on a standard 120 volt outlet; a full charge costs $12.57 to $25.32 at the US average rate of 18.16 cents per kWh.

Chargers matched to the Tesla Model 3, from its buying guide
Selection rule, in full
for the Tesla and model year selected, the rows the car's own buying guide prints: chargers that fit its charge port, the lowest verified price that reaches its onboard limit plugged in, hardwired and portable, and a cheaper, slower one where it exists. Rows are the lowest verified prices among the chargers that match, ties by name; nothing is ranked on quality.
The charge port for this model year is not verified, so no charger is matched; check the charge port door.

This model on each home charger
| Charger | 10 to 80% | 20 to 100% |
|---|---|---|
| 120 V outlet, 12 A | 44.4 h | 50.8 h |
| Mobile Connector, NEMA 14-50, 32 A | 8.3 h | 9.5 h |
| Wall Connector, 48 A | 5.6 h | 6.3 h |
Time is the energy the car draws from the wall divided by the power it can take: the lower of the charger's output and the car's own onboard limit. Energy for the session is the chosen share of EPA's kWh per full charge, measured at the wall, so charging losses are already inside it; the onboard limits are Tesla's own published figures. Rates are August 2026 residential averages by state from the EIA.

Hours are straight-line arithmetic: the share of a full charge divided by the power the car accepts. The last few percent before 100 run slower, so the 20 to 100 column is the floor for that session. Where a charger can deliver more current than the car's onboard charger takes, the extra amps go unused and the time does not improve; the table marks those cells. A range means the figure differs across the EPA-listed trims the row covers.
Sources: onboard limits from Tesla's Wall Connector charging page; energy per full charge from EPA fuel economy data; electricity rates from the U.S. Energy Information Administration (August 2026). Each row covers the trims Tesla's page names for that limit. Also left out rather than guessed: 10 EPA-listed trims whose name the source does not use (2026 Cybertruck Dual Motor AWD, 2026 Cybertruck Long Range (20in Cyber wheels), 2026 Model 3 Premium AWD, 2026 Model 3 Premium RWD, 2026 Model 3 Standard RWD, 2026 Model Y Standard AWD, 2026 Model Y Standard RWD (18in Wheels), 2026 Model Y Standard RWD (19in Wheels), 2025 Cybertruck Long Range, 2025 Cybertruck Long Range (20in Cyber wheels)).
Tesla charging questions
- Does the Wall Connector charge every Tesla faster than the Mobile Connector?
- No. The car takes the lower of the charger's output and its own onboard limit. Tesla publishes 32 amps (7.7 kW) for the Tesla Model 3 Rear-Wheel Drive, so a 48 amp Wall Connector leaves 16 amps unused and charges it no faster than a 32 amp supply. Trims with a 48 amp limit do charge faster on the Wall Connector.
- How much does it cost to charge a Tesla at home?
- A full charge costs $12.57 to $25.32 at the US average residential rate of 18.16 cents per kWh (EIA, August 2026), from EPA's measured energy per full charge for each model. For the 2026 Model 3 Performance that is $11.63 in Nevada, the cheapest state, and $43.12 in Hawaii, the most expensive.
