2027 Subaru Solterra AWD: home charging cost in Massachusetts

In Massachusetts, home electricity runs 30.06¢/kWh — put a 2027 Subaru Solterra AWD's EPA-rated 28 kWh/100mi against that and 100 miles costs $8.4, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 47.5% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Subaru Solterra AWD charged at home in Massachusetts costs about $1,261/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,142 a year.

What one full charge costs

A 2027 Subaru Solterra AWD needs roughly 80.5 kWh to reach its EPA-rated 288-mile range, which runs about $24.2 at 30.06¢/kWh in Massachusetts.

How this compares nationally

This combination ranks 15,666 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; Massachusetts alone ranks 49 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 Massachusetts electrician to quote the install before this math becomes a real decision.
