How this calculator works
For kWh/year, use the value directly. For kWh/100 cycles, divide by 100 then multiply by cycles per week × 365 ÷ 7. For kWh/cycle, multiply by annual cycles. Check the units: label schemes vary across appliance types and jurisdictions.
Cost in pounds = energy in kWh × electricity rate in pence ÷ 100. Monthly costs are annual costs divided by 12; daily costs are divided by 365. These are averages over a year. Calculations retain precision until display rounding.
Get a more useful estimate
Start with the rate on your bill and energy information for your exact model. A plug-in energy monitor can help measure suitable plug-in appliances; follow its safety instructions and power limits. Do not apply full-power wattage for 24 hours to a cycling fridge or freezer.
What is excluded?
Standing charges, gas, water, detergent, maintenance and purchase costs are excluded unless the tool explicitly asks for a purchase premium. Usage and tariffs can change. The reference tariff covers Great Britain and does not represent Northern Ireland or every contract.
