Massachusetts home charging cost for the 2026 Porsche Macan 4 Electric
At Massachusetts's residential electricity rate of 30.06¢/kWh, a 2026 Porsche Macan 4 Electric (rated 35.3 kWh per 100 miles by the EPA) costs $10.61 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is cheaper than gas here: 33.7% less than gas per mile, here specifically.
What a year of driving costs

Filling up the 2026 Porsche Macan 4 Electric, in dollars
Covering the 2026 Porsche Macan 4 Electric's EPA-rated 304-mile range takes about 107.3 kWh, which costs about $32.27 at Massachusetts's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
Where this ranks

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.
