The amount of electricity a toaster, or any appliance for that matter, uses will depend on its wattage. It will also depend on how long, and how many times you use it as power consumption is measured in kilowatt-hours. Toasters energy ratings ordinarily range between 800 and 1500 watts. So to determine how much electricity your toaster is using, and to, therefore, answer the burning question, we need to do some simple math. Multiply the wattage of your toaster by the number of hours you use your toaster per day. If you use a 1200W toaster for an average of 10 minutes, it will use 1200 x 10/60 watt-hours. Which means it uses 200w/h, which works out to 0.2 kW/h. If you use your toaster faithfully on a daily base, it will consume 6 kW/h monthly. Should your average monthly power consumption by, say, 60 kW/h, your toaster can be said to contribute a tenth of your energy bill. Whether this level of energy consumption is high or acceptable will vary from household to household. You can control the amount of energy your toaster consumes by selecting a make with a lower energy rating. Bear in mind, though, that a toaster with a lower rating may not be the most efficient.
