Compare appliance purchase and electricity costs
Compare the purchase price and running cost of two appliances over the same period.
Compare two options
Option B costs less
over 3 years of ownership
The extra purchase cost is recovered in about 2.89 years at this usage.
Example prices and power values describe hypothetical appliances, not tested products. Costs exclude installation, maintenance, financing and resale.
Compare equivalent jobs
In annual-energy mode, each annual electricity cost is kWh/year × your rate. The hours, days and months fields are not used. Preserve the label’s operating assumptions when comparing standardized annual figures; changing the tariff does not change the test schedule.
Use two appliances that can meet the same room’s needs. A lower-power model that cannot do the job is not an equivalent alternative. Enter measured average consumption under similar conditions where possible.
Total cost = purchase price + (annual running cost × years)
Break-even years = extra purchase cost ÷ annual energy savings
Prices and use remain constant in this model. Break-even is shown only when the higher purchase price comes with lower running costs; it does not predict product lifespan.
