About the site

Electricity costs should be easier to understand.

Know Your Power Bill is an independent website built to translate electricity rates, watts, kilowatt-hours, and vehicle efficiency into practical dollar estimates.

Useful before complicated

Our calculators are designed to answer everyday questions quickly, while still showing the assumptions behind the result.

Public data, clearly labeled

State electricity-price data come from the U.S. Energy Information Administration. We identify averages as averages rather than presenting them as individual utility tariffs.

Independent

Know Your Power Bill is not a utility company and is not sponsored by or affiliated with EIA or any electric utility.

How we work

Calculations you can inspect.

We publish the formulas and assumptions used by the calculators, and we automatically refresh the state-rate pages when newer EIA data become available. For details, see Data & Methodology.
