Understanding electricity rates in Montana

VoltSaga uses an estimated statewide residential rate of $0.124/kWh. That keeps the comparison useful across Montana, but your bill may differ because utilities set local tariffs and many plans use time-of-use pricing. Charging overnight on an off-peak plan can be materially less expensive than the statewide average.

For an apples-to-apples comparison, the calculator uses a typical gas vehicle rated at 27 MPG and a Montana gasoline planning price of $3.15 per gallon. It does not include insurance, financing, registration fees, tire wear, or home-charger installation.
