Three everyday questions
What does this appliance cost to run? How does it compare with another option? What do my selected appliances add up to? The three calculators are connected so an input can follow you from the first question to the next.
Your rate. Visible assumptions.
Electricity tariffs vary, and appliance labels use different units. You supply the rate and energy information that fit your situation. Every estimate states its source and assumptions, and the methodology explains the formulas.
Simple by choice
You do not need an account or an email address to calculate. Appliance inputs are processed in your browser. You can choose to save a budget on the same device or download a JSON copy.

The calculators are currently free. Advertising may support the site in the future. If advertising or optional analytics are enabled, the privacy notice and consent choices will describe them. The initial calculator version contains no affiliate product rankings or paid appliance recommendations.
