EV Charging Cost Calculator
Estimate your EV charging cost — by state, model, and charging type. Get accurate per-charge, per-mile, and monthly costs in seconds.
📐 How It's Calculated
Energy needed = (Target% − Current%) ÷ 100 × Battery Capacity
Energy from grid = Energy needed ÷ Charging Efficiency
Cost = Energy from grid × Electricity Rate
Efficiency: 90% for AC (home/public) · 93% for DC Fast. Rates from EIA state averages.

- ⚡ Charging efficiency losses (10–15%) are included in our calculator for real-world accuracy.
How Much Does It Cost to Charge an EV?
At the U.S. average residential electricity rate of $0.16/kWh, charging a typical EV (e.g., Tesla Model 3 with 75 kWh battery) from 20% to 80% costs about $7.20. A full 0–100% charge costs roughly $12–$14. However, your actual cost depends on your electricity rate, vehicle efficiency, and charging location.
- Home charging (Level 2): $0.12–$0.18/kWh → ~$0.03–$0.05 per mile
- Public Level 2: $0.20–$0.30/kWh → ~$0.07–$0.14 per mile
- DC Fast Charging: $0.30–$0.53/kWh → ~$0.12–$0.22 per mile
EV Charging Cost by State
Electricity rates vary significantly across the U.S. Here are the average residential rates (as of 2026) from the U.S. Energy Information Administration (EIA). Use our calculator above to get a precise estimate for your state.
| State | Rate ($/kWh) | Cost to charge (75 kWh, 20→80%) |
|---|---|---|
| Oklahoma | $0.08 | $3.60 |
| Washington | $0.09 | $4.05 |
| Texas | $0.12 | $5.40 |
| Florida | $0.13 | $5.85 |
| California | $0.22 | $9.90 |
| New York | $0.19 | $8.55 |
| Hawaii | $0.40 | $18.00 |

How the EV Charging Cost Calculator Works
Our calculator uses a transparent methodology to give you the most accurate estimate:
- Energy needed = (Target% – Current%) ÷ 100 × Battery Capacity (kWh)
- Energy from grid = Energy needed ÷ Charging Efficiency (90% for AC, 93% for DC Fast)
- Total cost = Energy from grid × Electricity Rate ($/kWh)
We also factor in charging losses (10–15% for AC charging) and time-of-use rates to reflect real-world conditions.
Home Charging vs Public Charging vs DC Fast Charging
The table below compares typical costs for a 75 kWh battery (e.g., Tesla Model 3) charged from 20% to 80% (45 kWh delivered to the battery).
| Charging Type | Rate ($/kWh) | Cost (45 kWh) | Cost per Mile |
|---|---|---|---|
| Home (Level 2) | $0.16 | $7.20 | $0.046 |
| Public Level 2 | $0.25 | $11.25 | $0.072 |
| DC Fast Charging | $0.40 | $18.00 | $0.115 |
EV Charging Cost Examples
Tesla Model 3 (75 kWh battery, 4.2 mi/kWh)
Charging from 20% to 80% (45 kWh) at the U.S. average rate of $0.16/kWh costs $7.20. Driving 40 miles per day costs $1.52 – about $46 per month.
Ford Mustang Mach‑E (88 kWh battery, 3.3 mi/kWh)
Charging from 20% to 80% (52.8 kWh) costs $8.45. Daily 40-mile cost: $1.94 – about $58 per month.
Chevrolet Bolt (65 kWh battery, 3.9 mi/kWh)
Charging from 20% to 80% (39 kWh) costs $6.24. Daily 40-mile cost: $1.64 – about $49 per month.
EV Charging Cost vs Gasoline
At $3.50 per gallon and 25 mpg, a gas car costs $0.14 per mile. An EV at $0.16/kWh and 3.5 mi/kWh costs $0.046 per mile – about 3× cheaper. Over a year (13,500 miles), the EV saves roughly $1,270 in fuel costs.
| Vehicle | Cost per Mile | Annual Cost (13,500 mi) |
|---|---|---|
| EV (home charging) | $0.046 | $621 |
| Gas car (25 mpg, $3.50/gal) | $0.140 | $1,890 |
| Annual Savings | — | $1,269 |
Frequently Asked Questions
How much does it cost to charge an EV at home?
Home charging costs $0.12–$0.18 per kWh on average, making a full charge for a 75 kWh EV about $12–$14. With off-peak rates, this can drop significantly.
Is EV charging cheaper than gas?
Yes. EVs typically cost $0.03–$0.05 per mile vs. $0.12–$0.18 for gas, saving $800–$1,500 annually.
Why does DC fast charging cost more?
DC fast chargers require expensive equipment and demand charges from utilities, leading to higher rates ($0.30–$0.53/kWh).
How does weather affect charging cost?
Cold weather reduces battery efficiency and range, increasing the energy needed per mile and thus the cost per mile.
What is charging efficiency?
Charging efficiency is the percentage of electricity from the grid that actually reaches your battery. AC charging is ~90% efficient; DC fast is ~93%.
