Editorial standards
Clear sources, visible assumptions and reproducible calculations.
What we publish
CostToRunIt publishes electricity-cost calculators and explanatory guides. We distinguish a published rate, a model-specific specification, an illustrative preset and a measured result. The appliance presets are estimates; this site does not claim to have independently tested those products.
Sources and automation
US residential price benchmarks come from the US Energy Information Administration. UK references identify the Ofgem period, payment method and geographic scope. Australian calculators ask for the applicable bill rate; their worked example price is not a national average. Shared templates combine the stated prices with appliance inputs and calculate the results. A page generated from these inputs is not a separately measured household bill. The methodology explains the arithmetic, period conventions and limitations.
External references are linked near relevant guidance. They support the stated method or background; a link to a government agency does not imply that it supplied or endorsed every appliance preset. We avoid attributing figures to a manufacturer without a model-specific reference.
Dates and corrections
Rate periods identify the observations in the data. A more recent rate period does not by itself mean a page’s appliance assumptions have been reviewed. We do not use the current calendar date as evidence of testing or invent reviewer identities, biographies or credentials.
Readers can report an error with a page URL, input values and supporting reference. A correction should identify what changed and why when it materially affects the explanation or result. An uncertain input should remain labelled as an estimate.
Advertising
Advertising, when enabled, is separate from the calculations. The cost formula does not include a paid placement or a preference for an appliance brand. The privacy policy describes configured analytics and advertising.
Calculator privacy
Calculator fields are processed in the browser without submitting those inputs to our server. Site searches are different: a search request includes its query in the URL and can appear in server logs. We do not describe those searches as private local calculations.
