Iowa home charging cost for the 2027 Subaru Solterra AWD

In Iowa, home electricity runs 13.77¢/kWh — put a 2027 Subaru Solterra AWD's EPA-rated 28 kWh/100mi against that and 100 miles costs $3.85, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 76% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2027 Subaru Solterra AWD costs roughly $577 a year to charge at home in Iowa, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,825 a year.

Cost of a full charge

Covering the 2027 Subaru Solterra AWD's EPA-rated 288-mile range takes about 80.5 kWh, which costs about $11.09 at Iowa's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 590 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Subaru Solterra AWD alone ranks 26 of 400 models for efficiency; Iowa alone ranks 9 of 51 states for electricity price.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
