The short answer: A 2026 Tesla Model Y Long Range AWD costs about $4.69 per 100 miles to charge at home in Iowa, and $15.34 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 17.06¢/kWh, up from 15.48¢/kWh in August 2025 and about 6% below the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $13.80 in a 30-mpg gas SUV at AAA’s Iowa average of $4.140 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.

EV vs gas in Iowa: cost per 100 miles

Iowa’s regular gas averaged $4.140 a gallon on October 28, 2026, the 21st-cheapest among the 50 states and the District (AAA). Electricity in Iowa is the 23rd-highest residential average among the 50 states and the District of Columbia.

Per-100-mile cost uses EPA combined ratings. The yearly column is the same rate times 12,000 miles, a round number chosen for comparison, not a measured average. Electricity is August 2026; gasoline is October 28, 2026.

Checked on the Model Y: 27.50 kWh/100 mi × $0.1706/kWh = 4.6915, which rounds to $4.69 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $4.140 = 13.7993, or $13.80. The break-even electricity price is $13.80 ÷ 27.50 kWh = 50.18¢ per kWh.

Utility EV rates in Iowa

The Alternative Fuels Data Center lists 3 utilities in Iowa with a residential EV time-of-use rate or managed-charging program: Black Hills Energy, Liberty Utilities and MidAmerican Energy Company. AFDC records the program type, not the price, so check the tariff before you assume an off-peak rate.

Why it matters: the state average above blends every rate plan. An overnight EV rate is usually the cheapest power a utility sells, and the car can be scheduled to charge only in that window. Put the off-peak price from your tariff into the calculator to see the difference.

Public charging in Iowa

The AFDC counted 1,306 public charging ports at 487 locations in Iowa on October 28, 2026: 720 Level 2 and 586 DC fast. AFDC also counts about 15,100 battery-electric vehicles registered in Iowa through 2025 (0.5% of light-duty registrations). That is about 11.6 EVs per public port, against 21.7 nationally, the 13th-fewest EVs per port among the 50 states and the District. The two counts are from different dates, so treat the ratio as a rough measure of how busy public charging is.

Paren’s Q3 2026 report does not state a Iowa fast-charging average, so this page uses its U.S. average of $0.540 per kWh (off-peak $0.438, peak $0.637). Tesla Supercharger members averaged $0.396 and non-members $0.569 nationally.

Fast chargers usually bill the energy delivered to the car, which is less than the EPA wall figure. A rough estimate of delivered energy, the wall figure × 0.894 (mean Level 2 AC efficiency from Sears, Roberts, and Glitman, 2014, not a DC fast measurement), puts the Model Y at about $13.28 per 100 miles at $0.540/kWh. Per-minute billing and idle fees are not modeled.

Cost to charge five common EVs in Iowa

Home cost uses 17.06¢/kWh. A full charge is the EPA wall energy to drive the rated range from empty, not a usable-battery figure. Public DC is EPA wall energy × $0.540/kWh (Paren, U.S. average); a station that bills energy delivered to the car will charge somewhat less, one that bills by the minute may charge more.

FAQ: charging an EV in Iowa

How much does it cost to charge an EV at home in Iowa?

At the EIA August 2026 average residential price of 17.06¢ per kWh, a 2026 Tesla Model Y Long Range AWD costs about $4.69 per 100 miles and $15.34 for the wall energy to drive its 327-mile EPA range. Across the five EVs on this page the home cost is $4.15 to $5.36 per 100 miles. EPA consumption is measured at the wall, so charging losses are already included.

Is charging an EV cheaper than buying gas in Iowa?

At home, yes, against a gas SUV. With AAA’s Iowa average of $4.140 a gallon for regular on October 28, 2026, a 2026 Honda CR-V FWD (30 mpg EPA combined) costs about $13.80 per 100 miles, versus $4.69 for the Model Y charged at the August 2026 residential average. A 2026 Toyota RAV4 hybrid (43 mpg) costs about $9.63, so home charging is also cheaper than that hybrid in Iowa. Home charging stays cheaper than the gas SUV until electricity reaches about 50.18¢ per kWh.

Is public DC fast charging more expensive than gas in Iowa?

For the Model Y at Paren’s Q3 2026 U.S. average of $0.540 per kWh, 100 miles of EPA wall energy costs about $14.85. That is more than the $13.80 the gas SUV spends on the same miles at the AAA average, and $10.16 more than charging at home. Prices at a given station vary, and some stations bill by the minute.

Do Iowa utilities offer EV charging rates?

The Alternative Fuels Data Center lists 3 utilities in Iowa with a residential EV time-of-use rate or managed-charging program: Black Hills Energy, Liberty Utilities and MidAmerican Energy Company. AFDC records the program type, not the price, so check the tariff before you assume an off-peak rate.

How many public EV chargers are there in Iowa?

The AFDC station count for October 28, 2026 shows 487 public charging locations in Iowa with 1,306 ports: 720 Level 2 and 586 DC fast. AFDC counts about 15,100 battery-electric vehicles registered there through 2025, or about 11.6 EVs per public port.

Is 17.06¢ per kWh the rate on my Iowa electric bill?

No. It is the statewide average residential retail price for August 2026 from EIA Table 5.6.A, and EIA marks 2026 values as preliminary. A time-of-use period, rider, tax, or fixed fee can move your all-in price. Open the VoltEdge charging-cost calculator and replace the prefilled average with the energy rate on your bill.
