Details
These notes make the assumptions explicit, especially where the same search query can mean slightly different things.
Electric bills usually charge for energy in kilowatt-hours, not watts. Use monthly kWh from your bill when possible.
Fixed fees and taxes can make your effective cents per kWh higher than the advertised energy rate.
The calculator does not model tiered pricing, demand charges, seasonal rates, or time-of-use schedules.
