Electric car running cost
Efficiency is wall-to-wheel, so charging losses are already in the kWh figure. The public price and the gas price are examples. Replace them with the prices where you charge and fill up.

Hyundai Ioniq 5 charging cost by trim
| Trim | kWh per 100 mi | EPA range | Cents per mile | 1,000 miles | 240 V charge |
|---|---|---|---|---|---|
| Standard range | 29.0 | 245 mi | 5.0 | $50 | 6.3 h |
| RWD | 30.0 | 318 mi | 5.2 | $52 | 9.1 h |
| AWD, 19 inch wheels | 31.7 | 290 mi | 5.5 | $55 | 8.2 h |
| AWD, 20 inch wheels | 34.5 | 269 mi | 5.9 | $59 | 8.2 h |
| AWD XRT | 35.8 | 259 mi | 6.2 | $62 | 8.2 h |
| N | 43.0 | 221 mi | 7.4 | $74 | 8.7 h |
Source: U.S. EPA and DOE, fueleconomy.gov, model year 2026, checked October 10, 2026. The highlighted trim is the one used for the headline figures. Prices: 17.23 cents per kWh, the 2025 US residential average from EIA Form EIA-861. The least efficient trim uses about 48 percent more electricity per mile than the most efficient.
About the Hyundai Ioniq 5 and its energy use
The Ioniq 5 is a crossover with six versions in the 2026 EPA data. The standard-range version is the most efficient at 29.0 kWh per 100 miles, and the high-performance N uses 43.0, about 48 percent more.
EPA gives times to charge from empty on a 240 volt connection between 6.3 and 9.1 hours. On a fast public charger, the charging speed is set by the car and the station, and the cost per kWh is usually higher than at home.

If you use public fast chargers
Public fast charging prices are set by each network and change with the place and the time. Check the price on the charger or in the app. This table shows what the Hyundai Ioniq 5 would cost per mile at four example prices, compared with charging at home at the US average.
| Price per kWh | Cents per mile | 1,000 miles | Versus home at US average |
|---|---|---|---|
| $0.30 | 9.0 | $90 | 1.7 times |
| $0.45 | 13.5 | $135 | 2.6 times |
| $0.60 | 18.0 | $180 | 3.5 times |
| $0.75 | 22.5 | $225 | 4.4 times |

Break-even gas price
| Where you charge | 25 mpg car | 30 mpg car | 35 mpg car | 40 mpg car |
|---|---|---|---|---|
| North Dakota price | $0.89 a gallon | $1.06 a gallon | $1.24 a gallon | $1.42 a gallon |
| US average price | $1.29 a gallon | $1.55 a gallon | $1.81 a gallon | $2.07 a gallon |
| Hawaii price | $3.03 a gallon | $3.64 a gallon | $4.24 a gallon | $4.85 a gallon |
If gas where you live costs more than the figure in the table, charging at home costs less per mile than driving a gas car with that fuel economy. If gas costs less, the gas car is cheaper per mile on fuel alone.
How we calculate it
Cost per mile is the EPA kWh per 100 miles, divided by 100, times the price per kWh. EPA measures efficiency at the wall, so charging losses are already inside the figure. Real efficiency changes with speed, temperature, tires and load, so use the EV charging cost calculator with your own numbers.
Hyundai Ioniq 5 charging cost questions
How much does it cost to charge a Hyundai Ioniq 5?
At about 30.0 kWh per 100 miles for the RWD version, 1,000 miles uses about 300 kWh. Use the tables on this page for the US average and for the cheapest and costliest states.
Why does the Ioniq 5 N use so much more electricity?
It is a performance version with more power and wider tires, so EPA measures about 43 kWh per 100 miles. The other versions use between 29 and 36.
How much does it cost to drive Hyundai Ioniq 5 100 miles?
At about 30.0 kWh per 100 miles and the 2025 US average price of 17.23 cents per kWh, 100 miles costs about $5.17 when you charge at home.
How much does a full charge cost for Hyundai Ioniq 5?
