What affects your real savings
- Where you charge. Home charging at Idaho's 11¢/kWh is the cheap case; leaning on public fast-charging narrows the gap.
- Your miles. More driving means bigger annual savings — the table assumes 12,000 mi/yr.
- The gas car you're replacing. Swapping a thirsty SUV or truck saves far more than replacing an efficient hybrid.
- The EV's price. Fuel savings repay the higher sticker over time — add both prices in the calculator for the break-even. Note the federal EV tax credit ended Sept 30, 2025; check any current Idaho state or utility incentives.
EV savings in Idaho: common questions
How much does an EV save in Idaho?
With Idaho gas around $3.45/gal and home electricity about 11¢/kWh, an efficient EV charged at home saves roughly $1,050 a year in fuel versus a typical 30-mpg gas car at 12,000 miles. The Tesla Model 3 tops the table here.
What does it cost to charge an EV in Idaho?
At Idaho's average home rate of 11¢/kWh, a 3.5 mi/kWh EV costs about 3¢ per mile to charge at home — far less per mile than gas at $3.45/gal. Public DC fast-charging costs more, so your home/public mix matters.
Did the federal EV tax credit change the math in Idaho?
The federal $7,500 EV tax credit ended September 30, 2025, so it no longer offsets an EV's price. Any current Idaho state or utility incentive still can — enter only that in the calculator's break-even, not the expired federal credit.
