EV Charging Cost Calculator & Cost Per Mile / 100 km Estimator

Q: Is charging an electric car cheaper than buying gasoline?

Yes, charging an EV at home typically results in a 60%-75% operational cost reduction compared to fueling an equivalent gasoline internal combustion engine (ICE) vehicle.

Q: Why does public DC fast charging cost so much more than home charging?

Public DC fast charging involves high-voltage infrastructure capital costs, commercial demand charges from utilities to support extreme power spikes, and network margin markups.

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

Charging a Tesla at home typically costs 3.5 to 4.5 cents per mile, whereas equivalent gasoline cars usually cost 12 to 15 cents per mile.

Q: Does cold winter weather increase the cost of charging an EV?

Yes, cold winter weather increases the cost of charging an EV by lowering battery efficiency and requiring cabin HVAC draw, leading to higher Wh/mi consumption.

Q: How much does it cost to charge an EV at a hotel or destination charger?

Destination chargers at hotels can range from complimentary (free for guests) to flat daily fees or standard Level 2 per-kWh rates depending on the property.

Calculate the exact cost to charge any electric vehicle at home or public DC fast chargers. Our ev charging cost calculator models AC-to-DC rectification losses, Time-of-Use off-peak tariffs, and public network pricing to reveal your true cost per mile and net savings over gas.

🇬🇧 United Kingdom

£0.24 / kWh

🇪🇺 Europe (Avg)

€0.28 / kWh

🇦🇺 Australia

$0.30 / kWh

Using the Quick Setup dropdown in our electric car cost per mile calculator above, you can instantly preload standard tariffs, gas prices, and regional currency settings to get an accurate comparison for your local market.

Understanding the 3 Levels of EV Charging Costs

Level 1: Standard 120V Outlet

The slowest method, utilizing a standard household outlet. While the base rate is your standard residential electricity tariff, Level 1 is the least efficient method due to high overhead losses (~20% to 25% of energy is lost to inverter heat).

Level 2: 240V Home Charging

The optimal daily setup. Requires a dedicated 240V circuit. Charging at 90% to 95% efficiency, Level 2 combined with an overnight Time-of-Use (TOU) utility rate is the absolute cheapest cost to charge ev at home vs public station.

Level 3: DC Fast Charging (Public)

Highway superchargers (Electrify America, Tesla Superchargers). While extremely fast, these networks charge a massive premium—often $0.40 to $0.60 per kWh—making them 3 to 4 times more expensive than home charging.

Electric Car Cost Per Mile Calculator: The Mathematical Formulation

1. Billable Grid Energy:

E_meter = (ΔSoC × C_battery) / η_charging

2. Total Charging Session Cost:

Cost_session = (E_meter × Rate_electricity) + Fee_session

3. Cost Per Mile (or km):

Cost_mile = (Wh_mi / (1,000 × η_charging)) × Rate_electricity

4. Gasoline Fuel Cost Per Mile Comparison:

Cost_mile_ICE = Price_gallon / MPG
