How much does it cost to charge an electric car in Hawaii?
Power is expensive in Hawaii: 40.5¢ per kWh is 153% above the national average, so time-of-use rates and overnight charging matter more here than almost anywhere. Gas is pricey too — around $4.49 a gallon, 28% above the $3.50 reference price — which pushes the savings back up.
At Hawaii's average rate, adding 100 miles to a Model 3 costs about $10.13 at home, and a full 60 kWh charge costs about $24.30. Over a year of 13,500 miles with 85% home charging, the EV charging cost in Hawaii comes to about $1,390 — roughly $116 a month. The U.S. average for the same car is $687.
EV charging cost in Hawaii: home vs station
Home charging at $0.405 per kWh works out to 10.1¢ a mile in a Model 3. Public DC fast charging, often around $0.45 per kWh, is 11.3¢ a mile. If you could only fast charge, the yearly bill would be about $1,519, still $375 less than gas. Ask your utility about EV or time-of-use plans; overnight rates are frequently well below the average shown here.

Is an electric car worth it in Hawaii?
Hawaii ranks #42 of 50 for EV fuel savings, near the bottom, so the case rests more on driving a lot, charging at home overnight and lower maintenance. For the Model 3 to cost the same to fuel as a Camry, gas in Hawaii would have to drop to about $3.29 a gallon. Add lower upkeep — no oil changes and less brake wear — and the yearly gap typically grows by a few hundred dollars. Whether the switch pays off depends mostly on the price difference you pay up front; enter it in the payback field above.
