The Chevrolet Bolt EV saves you $1,260 over 5 years compared to the Toyota RAV4 in Montana.
What Charging Actually Costs in Montana
Montana's average residential electricity rate is 11.7¢/kWh. That's below the national average, which makes EVs an especially good deal here. Your fuel savings will be higher than in most states.
| Charging Method | Rate | Annual Cost (15K mi) | Monthly | vs Gas |
|---|---|---|---|---|
| Home (off-peak) | 7.6¢/kWh | $319/yr | $27/mo | Save $1,371/yr |
| Home (standard) | 11.7¢/kWh | $491/yr | $41/mo | Save $1,199/yr |
| Public L2 | 21.1¢/kWh | $885/yr | $74/mo | Save $805/yr |
| DC Fast Charging | 41.0¢/kWh | $1,720/yr | $143/mo | +$30/yr |
| Gas (Toyota RAV4, 30 MPG) | $3.38/gal | $1,690/yr | $141/mo | Baseline |
Bottom line: home charging — especially off-peak — gives you the biggest savings. DC fast charging is convenient for road trips but costs almost as much as gas, sometimes more. For daily driving, plug in at home overnight.
Insurance: The Hidden EV Expense
This is where EVs lose some of their cost advantage. The Chevrolet Bolt EV costs about $199/month to insure in Montana — that's $21/month more than a comparable gas suv.
Chevrolet Bolt EV Insurance
$199/mo
$2,388/year
Toyota RAV4 Insurance
$178/mo
$2,140/year
EVs cost more to insure mainly because battery damage is expensive to repair (sometimes totaling the car) and fewer body shops are equipped to work on them. As the repair network grows, this gap should narrow.
Maintenance: Where EVs Really Shine
No oil changes. No transmission service. No spark plugs, timing belts, or exhaust systems. The Chevrolet Bolt EVneeds tires, brakes (which last longer thanks to regen braking), cabin filters, and occasional coolant. That's about it.
Chevrolet Bolt EV Maintenance
$396/yr
Toyota RAV4 Maintenance
$429/yr
That's $33/year less on maintenance — or $165 over 5 years. It won't pay for the car by itself, but it adds up.
