How Much Does It Cost to Charge a Tesla Model 3 at Home in 2026?
Charging a Tesla Model 3 at home costs between $9 and $10 for a full charge at the US average electricity rate of $0.16 per kWh. That comes out to roughly $0.035 per mile — making the Model 3 one of the cheapest cars to run in America.
The actual number depends on your trim (Standard Range vs Long Range), your state’s electricity rate, and whether you’re on a time-of-use plan. Here’s the real math with data sources so you can calculate it for your situation.
The Base Calculation
The Tesla Model 3 comes in two battery configurations:
- Standard Range (RWD): 57.5 kWh usable battery
- Long Range (AWD): 75 kWh usable battery (per Tesla’s official spec page)
At the US average residential electricity rate of $0.16/kWh (EIA, 2026), a full charge from empty to 100% costs:
Standard Range: 57.5 kWh × $0.16/kWh = $9.20 (before charging losses) Long Range: 75 kWh × $0.16/kWh = $12.00 (before charging losses)
Charging isn’t 100% efficient — typical Level 2 home charging loses about 10% to heat and conversion. So the actual electricity drawn from your panel is closer to:
Standard Range: 57.5 kWh ÷ 0.90 × $0.16/kWh = $10.22 Long Range: 75 kWh ÷ 0.90 × $0.16/kWh = $13.33
Most owners don’t charge from empty daily. If you drive 40 miles/day and the Model 3 gets ~4 miles/kWh (it’s highly efficient), you’re adding about 10 kWh per day — roughly $1.78/day or $53/month for the Standard Range.
Cost by State (Selected)
Electricity rates vary dramatically by state. Using EIA residential rate data:
| State | Avg Rate ($/kWh) | SR Full Charge | LR Full Charge | Cost per Mile |
|---|---|---|---|---|
| Louisiana | $0.12 | $7.67 | $10.00 | $0.027 |
| Washington | $0.11 | $7.02 | $9.17 | $0.024 |
| California | $0.27 | $17.25 | $22.50 | $0.061 |
| Hawaii | $0.41 | $26.19 | $34.17 | $0.093 |
| US Average | $0.16 | $10.22 | $13.33 | $0.036 |
A Model 3 owner in Washington pays about a third of what a California owner pays for the same charge.
Time-of-Use Plans Can Cut Costs 40-60%
Many utility companies offer time-of-use (TOU) plans where electricity is cheaper during off-peak hours (typically 11 PM – 5 AM). If you charge overnight on a TOU plan:
- Off-peak rate can drop to $0.08–$0.12/kWh (vs. $0.16 average)
- Standard Range full charge drops to $5.11–$7.67
- Annual savings (12,000 miles): $250–$450
The Model 3 is especially well-suited to TOU plans because it charges efficiently overnight — you can schedule charging in the Tesla app to start during off-peak hours.
Level 1 vs Level 2: Does Charger Type Affect Cost?
The charger type affects speed, not the per-kWh cost:
- Level 1 (120V standard outlet): ~3-4 miles of range per hour. Same $/kWh, just slower.
- Level 2 (240V, like a dryer outlet): ~25-30 miles of range per hour. Same $/kWh, much faster.
The electricity costs the same either way. Level 2 is recommended for convenience — the Model 3 can recover a full day’s driving in about 2 hours on a Level 2 charger.
Installation Cost for Home Charging
A Level 2 home charger installation typically costs $1,200–$2,000 total (hardware + electrician + permit). The Tesla Wall Connector hardware itself is about $450; the rest is labor and any panel upgrades.
There’s a federal tax credit (30C) covering 30% of installation costs up to $1,000 — but it’s currently set to expire June 30, 2026. Factor this into your timeline if you’re planning an installation.
Bottom Line
For most US Model 3 owners, home charging costs $35–$60 per month for typical driving — dramatically less than gasoline for a comparable sedan. The Model 3’s efficiency (4+ miles/kWh) makes it one of the cheapest vehicles to operate. The biggest variable is your local electricity rate, so check your utility’s rate sheet and ask about EV time-of-use plans.
