Quick Answer
In the examples below, home electricity is the cheaper daily-driving source. Tesla points owners toward home charging for daily use and Supercharging for road trips or long drives, and Tesla's Supercharging support page says site pricing varies and should be checked in the app or vehicle navigation.
Using official EPA-label math for a 2026 Model Y Long Range AWD entry at 27 kWh/100 miles, home charging at $0.16/kWh is about $4.32 per 100 miles. Using owner-data math with 3.7 miles/kWh and 90% home charging efficiency, the home figure becomes about $4.80 per 100 miles.
| Example scenario | Approx. cost per mile | Approx. cost per 100 miles | Notes |
|---|---|---|---|
| Home, EPA-label method | 4.32 cents | $4.32 | Uses 27 kWh/100 mi x $0.16 |
| Home, owner-data method | 4.80 cents | $4.80 | Uses 3.7 mi/kWh + 90% home efficiency |
| Supercharger at example $0.35/kWh | 9.46 cents | $9.46 | Example only |
| Supercharger at example $0.45/kWh | 12.16 cents | $12.16 | Example only |
Tesla Model Y Efficiency: What Number Should You Use?
For charging cost, efficiency matters more than battery size. Battery size helps estimate one charging session. Efficiency tells you what each mile costs.
Current 2026 FuelEconomy.gov entries for the Tesla Model Y range from 24 kWh/100 miles for the Standard RWD with 18-inch wheels to 32 kWh/100 miles for the Performance AWD. That works out to about 4.17 miles/kWh down to 3.13 miles/kWh on a wall-energy basis.
| Model Y trim | Official efficiency | Approx. miles/kWh | What it means for cost |
|---|---|---|---|
| 2026 Standard RWD 18" | 24 kWh/100 mi | 4.17 | Lowest electricity cost per mile in the current federal list |
| 2026 Long Range RWD | 25 kWh/100 mi | 4.00 | Efficient longer-range setup |
| 2026 Standard RWD 19" | 26 kWh/100 mi | 3.85 | Larger wheels raise energy use |
| 2026 Standard AWD | 26 kWh/100 mi | 3.85 | AWD adds some energy use |
| 2026 Long Range AWD | 27 kWh/100 mi | 3.70 | Middle of the current federal list |
| 2026 Performance AWD | 32 kWh/100 mi | 3.13 | Highest electricity cost per mile of the current group |
Tesla's public site uses names such as Premium RWD and Premium AWD, while FuelEconomy.gov currently uses names such as Long Range RWD and Long Range AWD. For charging-cost math, the marketing label is less important than the efficiency number tied to the trim and wheel setup you drive.
Two Ways to Calculate Model Y Charging Cost
Method A: EPA-label math
Cost per 100 miles = EPA kWh/100 mi x price per kWh
Method B: Custom driving-data math
Cost per mile = electricity price / charging efficiency / miles per kWhUse Method A when you are working from FuelEconomy.gov or an EPA window-sticker style number. Use Method B when you are working from your own Tesla Energy app or trip data and want to include home charging losses separately. EPA says EV label values already include charging losses; adding another loss factor to the same label number double-counts the loss.
Basic Formulas
Charging cost = kWh added x price per kWh
Cost per mile = price per kWh / miles per kWh
Adjusted home cost per mile = electricity price per kWh / charging efficiency / miles per kWh
Monthly charging cost = monthly miles / miles per kWh / charging efficiency x electricity priceFor a federal-label shortcut, use:
Cost per 100 miles = EPA kWh/100 mi x electricity priceNREL uses 90% AC charging efficiency as a modeling assumption in a national charging study. For an owner-data estimate, 90% is a defensible AC-charging assumption. Do not add it on top of EPA label efficiency.
Home Charging Cost for a Tesla Model Y
Home charging cost starts with your utility rate. EIA's Electricity Monthly Update showed a U.S. residential average of 17.65 cents/kWh for February 2026, with the issue released April 23, 2026. Actual rates vary by state, utility, and tariff.
The tables below use one calculation setup:
Cost per mile = $0.16 / 0.90 / 3.7 = $0.0480
Cost per 100 miles = $4.80| Monthly miles | Estimated wall kWh | Estimated monthly home charging cost | Estimated annual home charging cost |
|---|---|---|---|
| 500 | 150.15 kWh | $24.02 | $288.29 |
| 1,000 | 300.30 kWh | $48.05 | $576.58 |
| 1,500 | 450.45 kWh | $72.07 | $864.86 |
| 2,000 | 600.60 kWh | $96.10 | $1,153.15 |
As a federal-label cross-check, the 2026 Long Range AWD entry at 27 kWh/100 miles works out to $4.32 per 100 miles at the same $0.16/kWh rate.
Tesla Model Y Supercharger Cost
Tesla Superchargers are fast, but there is no single nationwide price. Tesla says owners are billed per kWh whenever possible, while some areas bill per minute. Tesla also says rates and peak times are shown in the vehicle navigation, and the app provides charging history and downloadable invoices.
For this guide, Supercharger prices stay labeled as example rates. Check the Tesla app or vehicle navigation before charging for the selected station price.
| Example Supercharger rate | Cost per mile | Cost per 100 miles | Cost for 500 miles | Cost for 1,000 miles |
|---|---|---|---|---|
| $0.30/kWh | $0.0811 | $8.11 | $40.54 | $81.08 |
| $0.40/kWh | $0.1081 | $10.81 | $54.05 | $108.11 |
| $0.50/kWh | $0.1351 | $13.51 | $67.57 | $135.14 |
These rows are price scenarios, not verified live station prices. In minute-billed locations, the cost structure can differ because Tesla uses speed-based billing tiers.
Home Charging vs. Supercharger Cost
The table below holds vehicle efficiency constant, then changes the charging source. It uses 3.7 miles/kWh, 90% home charging efficiency, $0.16/kWh home electricity, and example Supercharger rates of $0.30, $0.40, and $0.50/kWh.
| Charging type | Price per kWh | Adjusted cost per mile | Cost per 100 miles | Cost per 1,000 miles | Notes |
|---|---|---|---|---|---|
| Home charging | $0.16 | 4.80 cents | $4.80 | $48.05 | Owner-data example with 90% home efficiency |
| Supercharger | $0.30 | 8.11 cents | $8.11 | $81.08 | Example rate only |
| Supercharger | $0.40 | 10.81 cents | $10.81 | $108.11 | Example rate only |
| Supercharger | $0.50 | 13.51 cents | $13.51 | $135.14 | Example rate only |
At $0.16/kWh, home charging undercuts each Supercharger scenario. Supercharging buys speed, route coverage, and fewer charging stops.
Cost to Charge a Tesla Model Y from 20% to 80%
A 20% to 80% session is a familiar trip-planning frame. Tesla's battery-health guidance says vehicles with a recommended daily 80% limit should generally stay around that level for routine driving, with 100% saved for longer trips.
Tesla's public Model Y page does not publish a single usable-kWh battery figure for every trim. This section uses a labeled energy-added example instead of assigning one capacity to the full lineup.
| Charging scenario | Example energy added | Calculation | Estimated cost |
|---|---|---|---|
| Home at $0.16/kWh with 90% efficiency | 45 kWh to battery | 45 / 0.90 x $0.16 | $8.00 |
| Supercharger at example $0.40/kWh | 45 kWh billed | 45 x $0.40 | $18.00 |
The 45 kWh value is an example of energy added, not an official published usable battery capacity.
Cost to Fully Charge a Tesla Model Y
A full-charge price is easier to ask than it is to use for budgeting. Cost per mile and cost per 100 miles compare trims and charging sources more cleanly. For a single-session estimate, assume 60 kWh added to the battery:
Treat these as session examples, not Tesla-published full-battery prices for every trim. Many owners do not charge to 100% every day.
Monthly Tesla Model Y Charging Cost Examples
These scenarios use 3.7 miles/kWh, $0.16/kWh home electricity, 90% home charging efficiency, and an example $0.40/kWh Supercharger rate.
| Scenario | Monthly miles | Home wall kWh | Supercharger kWh | Estimated monthly cost | Estimated annual cost |
|---|---|---|---|---|---|
| Local driver, 95% home / 5% Supercharging | 500 | 142.64 | 6.76 | $25.53 | $306.31 |
| Average commuter, 90% home / 10% Supercharging | 1,000 | 270.27 | 27.03 | $54.05 | $648.65 |
| Heavy driver, 60% home / 40% Supercharging | 2,000 | 360.36 | 216.22 | $144.14 | $1,729.73 |
The cost moves with the charging mix. A Model Y that gets most of its energy at home stays cheaper to run than the same car during a month with frequent Supercharging.
Tesla Model Y Charging Cost vs. a Gas SUV
Gas cost per mile = gas price per gallon / MPG
$3.50 / 28 = $0.125 per mile| Vehicle or charging type | Assumptions | Cost per mile | Cost per 100 miles |
|---|---|---|---|
| Model Y at home | $0.16/kWh, 3.7 mi/kWh, 90% efficiency | 4.80 cents | $4.80 |
| Model Y at a Supercharger | Example $0.40/kWh, 3.7 mi/kWh | 10.81 cents | $10.81 |
| Gas SUV | $3.50/gallon, 28 MPG | 12.50 cents | $12.50 |
That comparison does not mean a Model Y always beats gas by the same margin. Change gas price, home electricity rate, driving efficiency, or Supercharger share, and the gap changes.
Does a Tesla Wall Connector Lower Charging Cost?
A Tesla Wall Connector mainly improves speed and convenience, not the utility's energy rate. It can help you capture cheaper overnight windows if your utility uses time-of-use pricing, but the device itself does not make electricity cheaper.
For related planning, see the home EV charger cost guide and the time-of-use EV charging guide.
Time-of-Use Rates and Overnight Charging
Time-of-use pricing changes the bill without changing the car. Tesla's Charge Stats page says owners can set a utility rate plan in the app and view home charging by off-peak, mid-peak, and peak periods.
| Input | Value |
|---|---|
| Standard home rate | $0.18/kWh |
| Off-peak home rate | $0.11/kWh |
| Monthly wall kWh for 1,000 miles | 300.30 kWh |
| Monthly savings | 300.30 x ($0.18 - $0.11) = $21.02 |
| Annual savings | $21.02 x 12 = $252.25 |
If your utility offers EV-friendly overnight pricing, scheduling home charging into the off-peak window can reduce Model Y charging cost without changing the vehicle.
What Changes Model Y Charging Cost
Tesla's range guidance and federal testing data both support these variables. Higher speeds, colder weather, less efficient wheel and tire setups, and more HVAC use can raise kWh per mile.
How to Calculate Your Own Cost
Pull the inputs from records you can verify: your utility bill, Tesla Charge Stats, the Tesla Energy app, charging invoices, and FuelEconomy.gov.
| Input | Where to find it |
|---|---|
| Home electricity rate | Utility bill or utility portal |
| Home charging data | Tesla Charge Stats in the app |
| Supercharger price | Tesla app or vehicle navigation pin before charging |
| Charging history and invoices | Tesla app |
| Driving efficiency | Tesla Energy app or trip energy data |
| Official efficiency | FuelEconomy.gov |
| Electricity market context | EIA electricity data |
For a faster estimate, use the CostToCharge.com EV Charging Cost Calculator, then adjust the result with your Supercharger share and Tesla app charging history.
Mistakes That Distort Model Y Charging Cost
Conclusion
At the rates used here, home electricity is the lowest-cost source for a Model Y. Superchargers are better understood as speed and travel infrastructure than as the cheapest day-to-day charging source.
Charging cost = kWh used x price per kWh
Cost per mile = price per kWh / miles per kWhKeep the efficiency method consistent. If you use EPA or FuelEconomy.gov label values, skip the extra charging-loss penalty. If you use your own miles/kWh from driving data, a separate home-efficiency adjustment can be appropriate. For Superchargers, use the price shown in the Tesla app or vehicle navigation before charging.
Frequently asked questions
How much does it cost to charge a Tesla Model Y at home?
In the home-rate scenario used here, a Tesla Model Y costs about 4.80 cents per mile or $4.80 per 100 miles when electricity is $0.16/kWh, efficiency is 3.7 miles per kWh, and home charging efficiency is 90%. Using official EPA-label math for a 27 kWh/100-mile Model Y, the same utility rate works out to about $4.32 per 100 miles.
How much does it cost to charge a Tesla Model Y at a Supercharger?
Station price varies. Tesla says Supercharger pricing is shown in the Tesla app or on the vehicle map pin before charging. At an example rate of $0.40/kWh and 3.7 miles per kWh, the cost is about 10.81 cents per mile or $10.81 per 100 miles.
Is Tesla Supercharging more expensive than home charging?
In the comparison shown here, yes. Home charging costs about 4.80 cents per mile, while a $0.40/kWh Supercharger session costs about 10.81 cents per mile.
How much does it cost to drive a Tesla Model Y 100 miles?
The examples in this guide put home charging at about $4 to $5 per 100 miles and the Supercharger scenarios at about $8 to $14 per 100 miles. Your result changes with the electricity rate, efficiency, and charging mix.
How much does Tesla Model Y charging cost per month?
The three scenarios below show about $25.53 per month for 500 miles with mostly home charging, $54.05 per month for 1,000 miles with a 90/10 home-Supercharger split, and $144.14 per month for 2,000 miles with a 60/40 split.
Does a Tesla Wall Connector save money?
Not directly. A Wall Connector mainly improves speed and convenience. It can help you use cheaper overnight time-of-use pricing if your utility offers it, but it does not make electricity cheaper by itself.
Is charging a Tesla Model Y cheaper than gas?
At the example home rate used here, yes. Home charging is about 4.80 cents per mile, while a gas SUV at 28 MPG and $3.50 per gallon costs about 12.50 cents per mile. The gap narrows as Supercharging becomes a larger share of charging.
How do I check Tesla Supercharger prices?
Check the selected Supercharger pin in the Tesla app or on the vehicle touchscreen before charging. Tesla also provides charging history and downloadable invoices in the app.
Does cold weather increase Tesla Model Y charging cost?
Yes, it can. Cold temperatures can reduce efficiency and increase energy use, especially when cabin heating is needed. That raises cost per mile even if the price per kWh does not change.
What is the best way to lower Tesla Model Y charging cost?
Charge at home when possible, use off-peak rates if available, monitor driving efficiency, maintain tire pressure, and reserve Supercharging mostly for road trips and long drives.
