Every cost on CentsPerHour is an estimate. We calculate it from an appliance’s wattage, how long it runs, a typical duty cycle and a price per kWh. Each of these can differ from your real situation.

Your actual cost may be higher or lower because of your exact tariff, slab or time-of-use rates, regional prices, taxes and fees, the age and settings of your appliance, the weather, and standby power. Official prices are averages for a past period and may not match what you pay today. Appliance wattages on our pages are typical ranges, not measurements of your appliance.

For the most accurate result, use the price per kWh from your own bill and the wattage from your appliance’s label.

Nothing on this site is electrical, financial or other professional advice. Do not use our results as the only basis for a major purchase, a contract or a financial decision.

For wiring, generators, transfer switches or any other electrical work, hire a licensed electrician. Electrical work can be dangerous, and in many places it must be done by a qualified person by law. Our calculators cannot tell you whether a circuit, cable or generator is safe or big enough.

Our default prices come from official sources, including the U.S. Energy Information Administration, Eurostat, Ofgem and national energy regulators and utilities. We show each source and data period, and we check data before publishing it, but we cannot guarantee that a third-party source is free of errors.

We link to other websites, products and services. Some links are affiliate links. A link is not a guarantee of a product, service or website.

The bill analyzer can read numbers from a photo of your bill using AI. AI can misread a figure, so please check the numbers it finds against your bill before relying on the result.

If you think a result or a fact on the site is wrong, email uzairxdev@gmail.com. We check every report and fix confirmed errors.
