About Electricity Cost Estimator
A focused website for one practical task.
Purpose
Compare appliance running costs using average power, daily hours, period days, and your per-kWh rate. For cycling appliances, average measured power is more accurate than maximum nameplate power.
The tool is intended to work without accounts. In this starter version, calculations run in the browser and there is no form-submission backend.
Accuracy and limitations
Actual bills include other loads, fixed fees, taxes, rate tiers, and seasonal behavior. This is not electrical safety advice.
Formulas and assumptions are shown so visitors can review the result; no particular outcome is guaranteed.
