What to include
If you are suggesting a correction, include the appliance name, model if available, wattage source, and the page URL. Clear source details make updates much easier to verify.
For calculator feedback, include the values you entered for watts, hours, and electricity rate, along with what result you expected. This helps us reproduce the estimate and check whether the page copy needs clarification.
We review practical corrections and appliance suggestions for future site updates.
Editorial corrections
WattCostGuide is built around transparent formulas and practical wattage ranges. If a page lists a wattage range that seems too high, too low, or unclear for a common appliance type, send the source and we will review it for a future update.
We cannot provide utility billing advice for a specific account, but we can improve calculator examples, clarify formulas, and update educational explanations when better information is available.
