Every dollar figure below is computed from the same disclosed formula — no black box. Your actual cost scales directly with your local electricity rate: North Dakota averages about 12.4¢/kWh, Hawaii 46.6¢, so a "full tank" for a Model Y can genuinely range from about $11 to $44 at home.

Math: usable battery kWh ÷ 88% charging efficiency × 18.83¢/kWh at home (EIA US residential average), and battery kWh × $0.42/kWh at a Supercharger (typical national average — rates vary by site and time of day). ¢/mile uses each variant's EPA range. Full 0→100% shown; real sessions are usually 10-80%. *Tesla doesn't publish battery capacities — usable-capacity estimates from independent pack data.
Home charging costs roughly 40-45% of Supercharger pricing per kWh at national averages — about 4.6-6¢ per mile for a Model 3/Y versus 9-13¢ at a Supercharger. The home figure includes the ~10-15% energy overhead of AC charging (the wall meter records more kWh than the battery stores); DC fast charging bills you for delivered energy. If your utility offers a time-of-use EV plan, overnight rates of 8-12¢/kWh can cut the home numbers in this table nearly in half.
Tesla doesn't publish battery capacities, so we use usable-capacity estimates from independent pack teardown and certification data (about 69.5 kWh for Standard trims, 78-82 kWh for Premium/Performance 3/Y, ~96 kWh for S/X and ~123 kWh for Cybertruck). Real-world sessions are also rarely 0→100%: a typical 10-80% Supercharger stop on a Model Y Premium RWD is about 55 kWh — call it $23 at $0.42/kWh.
Off-peak Supercharging (typically ~$0.25-0.35/kWh) beats the daytime rate by 10-20¢. Some inventory Model S/X purchases since April 2026 bundle lifetime free Supercharging via the Luxe Package — which makes the right column of our table $0 for those cars.
How much does it cost to fully charge a Tesla Model Y at home?
About $15-18 at the April 2026 US-average rate of 18.83¢/kWh — a Model Y Premium RWD works out to roughly $16.90 including charging losses, or about 4.7¢ per mile against its 357-mile EPA range.
How much is a Supercharger session?
A typical 10-80% stop delivers 45-60 kWh on a Model 3/Y — about $19-25 at a typical $0.42/kWh. A full 0-100% equivalent would run $29-34 on a Model 3/Y, $40 on a Model S, and up to $52 on a Cybertruck.
Is charging a Tesla cheaper than gas?
At home, substantially: 4.6-6¢ per mile for a Model 3/Y versus roughly 12-15¢ per mile for a comparable 25-30 mpg gas car at mid-2026 pump prices. Relying mainly on Superchargers narrows that advantage to modest-or-none in high-rate regions — home charging is where the savings live.
What's the cost per mile of a Cybertruck?
The highest of any Tesla: about 8.1¢ per mile at home-average rates and roughly 16¢ per mile on Superchargers, a consequence of the ~123 kWh pack moving 6,600+ lbs.
