2026 Tesla Model 3 Performance, HI Charging Cost

Charging a 2026 Tesla Model 3 Performance at home in Hawaii

At Hawaii's residential electricity rate of 45.95¢/kWh, a 2026 Tesla Model 3 Performance (rated 29.6 kWh per 100 miles by the EPA) costs $13.59 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. That works out to 15.1% cheaper per mile than gasoline in Hawaii, charging at home is cheaper than gas here.

Annual cost, at 15 thousands miles a year

Hawaii owners putting 15,000 annual miles on a 2026 Tesla Model 3 Performance spend about $2,039 on home electricity, compared to about $2,403 a gas-car equivalent would spend on fuel. Call it about $364 saved annually, at this mileage.

What one full charge costs

At Hawaii's rate, fully covering this 2026 Tesla Model 3 Performance's 309-mile EPA range costs about $42.01 (91.4 kWh), the energy the EPA test actually used, not the battery's rated size.

Where this ranks

Among all 20,400 state-and-model combinations this site tracks, charging a 2026 Tesla Model 3 Performance in Hawaii ranks 19,729 for cost savings versus gas, 1 being the best deal nationally. Separately, the Tesla Model 3 Performance ranks 52 of 400 EV models for raw efficiency, and Hawaii ranks 51 of 51 for cheapest residential electricity.

Next step: home charger installation

Everything above is the per-mile and per-year cost once a home charger exists, getting one installed is a separate electrical job whose price depends on your panel and wiring, not the state average used here.

Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.
