What Energy Cost Checker is

Energy Cost Checker estimates electricity costs from the numbers you enter and from published rate and appliance data. Every calculator shows its formula and its source so you can check the result yourself.

Not professional advice

Results are planning estimates, not a bill guarantee, an energy audit, or financial, legal, or engineering advice. Actual costs depend on your utility's full tariff, taxes, and meter, which this tool does not fully model.

Your responsibility

You're responsible for verifying any number before relying on it for a purchase, budgeting, or repair decision. Where you enter your own rate or usage figures, Energy Cost Checker trusts what you provide.

Availability

Energy Cost Checker is provided "as is," without warranty of any kind. Calculators, data sources, and this site may change or become unavailable without notice.

Liability

To the extent permitted by law, Energy Cost Checker and its operators aren't liable for decisions made using this site's estimates.
