EV vs gas car — annual fuel cost
The Tesla Model Y Performance at home rates compared against a typical 28-mpg gas car and a 40-mpg hybrid at the Hawaii fuel price ($4.85/gal).
| Annual mileage | Tesla Model Y Performance (home) | 28-mpg gas | 40-mpg hybrid | EV savings vs gas |
|---|---|---|---|---|
| 6,000 mi | $766 | $1039 | $728 | $273 |
| 10,000 mi | $1277 | $1732 | $1213 | $455 |
| 12,000 mi | $1533 | $2079 | $1455 | $546 |
| 15,000 mi | $1916 | $2598 | $1819 | $682 |
| 20,000 mi | $2554 | $3464 | $2425 | $910 |
Home vs public DC fast charging
Home charging is the default cost optimization. Public DC fast charging in Hawaii runs about 1.4× the home rate. For 12,000 miles/yr entirely on DC fast, annual fuel cost would be $2158 vs $1533 at home — a $625 penalty. Apartment dwellers and road-trippers should price this in; daily commuters with home Level 2 can usually ignore public chargers.
DC fast rate is a network average (Electrify America + EVgo + Tesla Supercharger + ChargePoint). Real prices vary by location, time of day, and membership tier.
EV incentives in Hawaii
Hawaii does not currently run a state-level EV purchase rebate. Federal Section 30D credit of $7,500 still applies for qualifying vehicles (US-assembled with sourced battery components, MSRP cap, household income cap). Check the EV tax credit eligibility list for your vehicle. Some utilities offer charger installation rebates — check with your local utility.

Common questions
- How much does it cost to charge a Tesla Model Y Performance at home in Hawaii?
- About $12.77 per 100 miles at the Hawaii residential electricity rate of 41.20¢/kWh (EIA). For comparison, a 28-mpg gas car at local gas prices costs $17.32 per 100 miles. Annual savings at 12,000 miles: ~$546.
- Home charging vs public DC fast charging — what's the difference in Hawaii?
- Public DC fast charging in Hawaii averages ~58¢/kWh — that's 1.4× home rates. A 100-mile session costs roughly $17.98 at public chargers vs $12.77 at home. For daily commuting, home charging pays off. Public fast charging is for road trips and apartment dwellers without home charging access.
- Are there EV incentives in Hawaii?
- Hawaii does not currently run a state-level EV purchase rebate. The federal Section 30D tax credit ($7,500) still applies for qualifying vehicles, and your utility may run separate charger-installation rebates.
- Does winter weather affect charging cost in Hawaii?
- Yes — cold weather can reduce EV efficiency by 15-30% (battery + heater draw). The numbers above use EPA combined ratings; budget +20% for sustained sub-freezing temps. Hot-state drivers see less impact, but AC use in extreme heat also reduces range.
