Pick your Tesla, your charge levels, and where you're plugging in — get cost, time, and range added instantly.
Home charging, Supercharging, and public Level 2 all cost and take wildly different amounts. This calculator uses your Tesla's actual battery size and efficiency to show the real cost, real time, and real savings vs. gas for any charge you're about to do.
Cost to charge
Same charge, four ways to plug in.
Energy needed is your model's battery capacity multiplied by the percentage you're adding. Charging time divides that by an effective charging rate for your chosen source — Superchargers taper well below their peak rate as the battery fills, so this uses a realistic session average rather than the peak number you see advertised. Range added comes from your model's rated efficiency (kWh per mile).
Gas comparison assumes a 32 mpg average gas car and a $3.50/gallon national average price, so you can see the real cost difference for the exact miles this charge will give you.
Yes, usually. Supercharger rates run roughly $0.28–$0.44 per kWh depending on location and time of day, while home electricity averages around $0.16 per kWh nationally — often 2–3x cheaper.
Lithium-ion batteries accept charge fastest between roughly 10% and 70%, then taper to protect battery health as they approach full. This calculator uses an average effective charge rate to account for that taper.
Tesla recommends keeping daily charging around 80-90% and reserving 100% charges for road trips, since consistently charging to 100% and letting the battery sit full can accelerate long-term battery degradation.
It depends heavily on your electricity rate and local gas prices, but most Tesla owners charging primarily at home save 50-70% per mile compared to an average gas car.

Charging times and costs are estimates based on typical battery capacities, national average electricity rates, and published Supercharger pricing ranges. Actual charge speed varies by battery temperature, state of charge, charger availability, and Tesla's live pricing at each location.
