2027 Subaru Solterra 20 AWD: home charging cost in Ohio
In Ohio, home electricity runs 18.53¢/kWh — put a 2027 Subaru Solterra 20 AWD's EPA-rated 28.9 kWh/100mi against that and 100 miles costs $5.36, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 66.5% less than gas per mile, here specifically.
What a year of driving costs
Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Subaru Solterra 20 AWD charged at home in Ohio costs about $804/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,599 a year.
Cost of a full charge
A 2027 Subaru Solterra 20 AWD needs roughly 80.4 kWh to reach its EPA-rated 278-mile range, which runs about $14.9 at 18.53¢/kWh in Ohio.
How this compares nationally
This combination ranks 6,331 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Subaru Solterra 20 AWD alone ranks 35 of 400 models for efficiency; Ohio alone ranks 34 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.
Ask a licensed Ohio electrician to quote the install before this math becomes a real decision.
