How much does it cost to charge a Hyundai Ioniq 5 in California?

California's 12-month average rate, 32.3¢/kWh, is 79% above the U.S. average of 18.0¢/kWh, so the Hyundai Ioniq 5 costs $4.15 more per 100 miles here than at the national rate.

Rates in California are rising: the latest 12-month average is 3.7% higher than in the 12 months before.

In the last 24 months both the cheapest and the most expensive month fell in spring, so the swing reflects price changes rather than a seasonal pattern: April 2025 at 27.8¢/kWh and April 2026 at 35.3¢/kWh, which moves the Hyundai Ioniq 5's monthly charging cost between $82 and $104. The latest published month, August 2026, came in at 29.8¢/kWh, 8% below the 12-month average.

Of the 5 states covered so far, California is the most expensive place to charge the Hyundai Ioniq 5; in Washington it costs $4.12 per 100 miles.

At 29.0 kWh per 100 miles, the 2027 Hyundai Ioniq 5 Standard Range uses less energy than 82% of the 171 2027 EV versions EPA has tested.

EPA rates the 2027 Ioniq 5 Standard Range at the same efficiency as the 2026 version, 29.0 kWh per 100 miles, with the same 245-mile range.

Across all 5 trims of the 2027 Ioniq 5, cost per 100 miles in California ranges from $9.38 for the Standard Range to $11.57 for the AWD XRT, a difference of $267 a year at 1,016 miles a month.

EPA estimates 6.5 hours to charge the Ioniq 5 Standard Range from empty on a 240-volt Level 2 home charger, short enough to finish overnight. At 1,016 miles a month (about 33 miles a day), a day's driving takes roughly 50 minutes on a Level 2 charger.

Electricity would have to cost more than 62.2¢/kWh, 1.9 times California's rate, before the Hyundai Ioniq 5 cost more per mile than the 2026 Hyundai Tucson FWD. Put the other way, gas would have to fall below $2.63 a gallon.

Gas costs use EIA's California retail average for regular gasoline ($5.05 a gallon over the same 12 months, 40% above the U.S. average of $3.61) and the 2026 Hyundai Tucson FWD's EPA rating of 28 mpg combined.
