The power consumption of a toaster depends on the number of slices of bread it can take at a time. Using the below calculator you can calculate power consumption of a 2 slice toaster and 4 slice toaster.
The power consumption of a 2 slice toaster is between 700 watt to 1000 watt, with an average being 750 watt.Whereas the power consumption of a 4 slice bread toaster is between 1200 watt to 2500 watt, with an average value being 1400 watt.
Even though the wattage of electric toaster is high their operational time is less hence overall power consumption is less.
Toaster Rated Power:
To calculate the power consumption of your toaster you need to know it’s rated power.
Most 2 slice bread toaster has rated power between 700 watt to 1000 watt, with 750 watt being an average value. If you have a 2 slice bread toaster take 750 watt for all the calculation.
Whereas a 4 slice bread toaster has rated power between 1200 watt to 2500 watt, with 1400 watt being an average value. If you have a 4 slice bread toaster take 1400 watt for all the calculation.
If you want to know your toaster’s exact wattage then look at the specification sticker at the bottom of the toaster or just go to amazon and find your toaster or one which is similar to yours and check the product description to know it’s wattage.
I have pulled up details of a 2 slice and slice toaster from amazon for your reference.
Toaster Power Consumption Calculator:
To calculate your toaster power consumption and interpret the results correctly you need to know and understand the following four parameters:
- Wattage: Wattage is the rate at which your toaster consumes power. A 800 watt toaster uses 800 watts of power every hour.
- Operational Hours: Operational hours is the number of hours you toaster is in operation. For example most toaster run for 10 minutes in a day, hence you can put 10 / 60 = 0.166 hour in the operation hours tab.
- Electricity Tariff: Electricity tariff is the amount your electricity provider charges you for one unit of electricity. I live in Mumbai, India here electricity tariff is Rs 12 / kWh. Type the electricity tariff in your area.
- Unit Of Electricity (kWh): The power consumed by any device is measured in units of electricity (kWh). For example a 500 watt AC running for 8 hours will consumes 500 watt X 8 hours = 4000 watt hours or 4 kWh of electricity.
Now that you know all the above parameter it’s time to use the calculator below.
How to interpret Power Consumption Results:
The calculated results are approximate values and you can expect 10 % error on either side.
If you are not satisfied with an approximate value and want to know exact power consumption of your printer then use a Kill A Watt meter.
Calculate Power Consumption Of A Toaster Using a Kill A Watt Meter:
Kill a watt meter is a simple device used to calculate power consumption of any device.
You can buy it from amazon using this link. Kill A Watt Electricity Usage Monitor
To use the Kill A Watt meter first connect your toaster plug to the Kill A Watt meter and then plug the Kill A Watt meter in your wall socket.
Then start using your toaster the way you do normally and you can see in real time how many kWh (units) of electricity your toaster is using.
Check out this tutorial video from altE to understand how to use a kill A Watt Meter to track your appliance energy consumption.
After calculating the results you would agree that even though the wattage of a toaster is high, their monthly power consumption is less because their operational hours is less (20 minutes / day at max). Hence don’t worry about the the power consumption of your electric toaster and happy toasting.
