How much does it cost to charge a Tesla at home?

Multiply wall energy by your utility rate. Wall energy is higher than battery energy because charging is not 100% efficient. Enter the rate from your electricity bill for a local estimate.

How much does a Tesla Supercharger cost?

Supercharger pricing varies by station, location, and time. This calculator does not fetch live prices, so enter the per-kWh price shown in the Tesla app or at the station.

Is charging a Tesla cheaper than buying gas?

It can be, especially with lower home electricity rates, but the result depends on driving efficiency, charging mix, gas price, and the comparison vehicle's MPG. All of those assumptions are editable here.

Why is the 0-100% estimate different from a normal charging session?

The 0-100% figure is a standardized comparison based on estimated usable capacity. Most drivers charge across a smaller range, and actual energy use changes with weather, speed, battery temperature, and accessories.

How Much Does It Cost to Charge a Tesla?

Q: How much does it cost to charge a Tesla?

The cost depends on battery energy added, charging loss, and the price per kWh. With the calculator defaults, a 20% to 80% Model 3 charge costs less at home than at the entered Supercharger rate.

Calculate Tesla charging costs at home or at a Supercharger by model, electricity rate, battery level and annual mileage.

How the Tesla charging cost calculator works

The calculator keeps a single charging session separate from long-term driving cost. Every result comes from the inputs shown above.

One charging session

Battery energy added = usable capacity × (target SOC - starting SOC).

Wall energy = battery energy added ÷ charging efficiency.

Session cost = wall energy × the home or Supercharger rate.

Example: a 75 kWh usable battery charged from 20% to 80% adds 45 kWh. At 90% efficiency, the charger supplies about 50 kWh.

Long-term driving cost

EPA/DOE monthly wall energy = miles × wall-side Wh/mi ÷ 1,000. The published efficiency value already includes charging loss, so the calculator does not add that loss again.

Tesla trip-meter mode

A Wh/mi value read from the Tesla Trips or Energy screen is battery-side. In that mode, wall energy = miles × Wh/mi ÷ 1,000 ÷ charging efficiency.

More than battery size × rate

Compared with a basic charging-cost formula, this calculator adds:

Separate scopes: one session, full-charge benchmark, distance cost, monthly budget, and annual budget.
A valid charging mix: one slider always keeps Home and Supercharger shares at 100%.
Energy-basis control: EPA/DOE wall-side estimates and Tesla battery-side trip data use different formulas.
Local inputs: official state averages remain editable for a real utility tariff or live Supercharger price.
A like-for-like gas check: recurring energy cost is compared separately from ownership costs.

Why the result is still an estimate

Usable battery capacity varies by model year, trim, software buffer, temperature, and battery condition. Driving energy also changes with speed, weather, elevation, tires, cabin conditioning, and accessory loads.

State electricity prices are planning averages, not utility tariffs. Tesla Supercharger prices can vary by location and plug-in time. Replace both rates with the prices you actually expect to pay.
